Keeping your lawn edges crisp and your fence lines clean takes the right tool for the job. After testing these string trimmers across weeks of real yard work, I can tell you that not every model lives up to its marketing claims. The best string trimmers balance power, comfort, and ease of use in ways that matter when you are actually out there sweating in the sun.
Our team put each of these trimmers through the same routine: thick weeds along a wooden fence, overgrown garden beds, tight corners around trees, and standard edge trimming after mowing. I paid close attention to the things that frustrate real owners. Line loading systems that jam, batteries that die before you finish, handles that leave your forearms aching after twenty minutes, and motors that bog down the moment they hit something thicker than a dandelion.
What I found after all this testing is that the string trimmer market has changed dramatically in 2026. Battery powered trimmers now rival gas models for most homeowners. They start instantly, produce no emissions, require almost no maintenance, and deliver enough runtime to finish a typical yard. The gap between cordless and gas performance that existed just five years ago has largely closed for residential use.
Innovative line loading systems have also eliminated what was arguably the single most annoying part of trimmer ownership. The EGO PowerLoad system, WORX Command Feed, and BLACK+DECKER EasyFeed all approach this problem differently, but each one reduces the frustration of dealing with tangled, broken, or jammed line. If you have ever spent twenty minutes on your garage floor trying to rewind a trimmer spool, you know how significant this improvement is.
Whether you have a small city lot with minimal edging needs or a sprawling suburban yard with extensive fence lines, garden beds, and tree bases to maintain, this guide covers eight models that earned their spot through hands-on testing. I tested corded electric trimmers, cordless battery platforms, and a gas-powered option to give you a complete picture of what is available.
I broke down every model by who it suits best, where it falls short, and the technical details that actually affect your buying decision. You will not find recycled spec sheets here. Instead, you will find honest observations from someone who has been maintaining lawns long enough to know the difference between a trimmer that lasts for years and one that frustrates you by midsummer. Let me walk you through what I found.

Top 3 Picks for String Trimmers in 2026
EGO Power+ 15-Inch ST1511T
- PowerLoad Technology
- 45 min runtime
- 15-inch swath
- Brushless motor
The EGO Power+ ST1511T takes our top spot because it solves the biggest headache in trimmer ownership with its PowerLoad system.

1. EGO Power+ ST1511T 15-Inch with PowerLoad Technology
EGO Power+ 15" Cordless Weed Trimmer with Battery and Charger - ST1511T
15-inch swath
PowerLoad tech
45 min runtime
Brushless motor
10.27 lbs
Pros
- PowerLoad makes line loading nearly effortless
- 45 minutes of runtime handles most yards
- Professional-grade 0.095 inch line
- 5-year tool warranty with 3-year battery warranty
Cons
- Heavier than budget options at over 10 lbs
- Some users report PowerLoad system learning curve
The first time I used the EGO Power+ ST1511T, I realized why this trimmer consistently tops professional reviews from sites like Pro Tool Reviews and Wirecutter. The PowerLoad technology is not just a gimmick. It genuinely eliminates the most frustrating part of owning a string trimmer. You feed the line through the head, press a button, and it winds itself. No more taking the spool apart on your garage floor while line tangles in every direction.
In my testing, the 15-inch cutting swath made quick work of my normal trimming route. What usually takes me about 25 minutes with a smaller 12-inch trimmer took roughly 18 minutes with the EGO because each pass covers 25 percent more ground. The brushless motor delivers consistent power through thick patches of crabgrass without bogging down or requiring me to slow my pace.
Battery life landed right around the claimed 45 minutes during normal edge trimming. When I pushed it through heavier weeds along my fence line, including some woody stalks that had been growing for weeks, I got about 35 minutes before needing a recharge. That is still enough to finish a typical suburban yard on one charge. The 56V 2.5Ah battery recharges in under an hour, so even if you run out, the downtime is minimal.
The telescopic aluminum shaft adjusts easily to accommodate different user heights. I am about 5 foot 10, and I found the default length comfortable, but the adjustment range should handle users from roughly 5 foot 2 to 6 foot 4 without issues. The variable speed control is a feature I grew to appreciate. Running on low speed for light trimming along the sidewalk extends battery life significantly.
Cranking the speed to high for thick weeds near the fence drains the battery faster but powers through stuff that would stall a lesser trimmer. I noticed a clear difference in how the EGO handled tall, wet grass compared to the 20V models from BLACK+DECKER and WORX. The 56V platform simply has more torque available when you need it.
At 10.27 pounds, this is one of the heavier options in our lineup. I noticed the weight after about 30 minutes of continuous use, particularly in my forearms and shoulders. The balance is good thanks to the battery placement at the rear of the shaft, which counterbalances the motor. If you have a very large property or struggle with arm fatigue during extended use, you may want to consider the lighter EGO ST1502SA instead.
The EGO platform is a major selling point if you own or plan to buy other EGO tools. The 56V ARC Lithium battery works across their entire lineup, including push mowers, backpack blowers, chainsaws, hedge trimmers, and snow blowers. That shared battery ecosystem adds real long-term value to this purchase, since each additional EGO tool you buy effectively comes without a battery cost if you already own one.
The 5-year tool warranty and 3-year battery warranty are among the best in the cordless industry. Most competitors offer 2 to 3 years on the tool and 1 to 2 years on the battery. This longer warranty period reflects EGO’s confidence in their build quality and gives you protection against premature failure.
Battery Runtime and Charging Details
The included 2.5Ah battery delivers 45 minutes of runtime under normal trimming conditions and recharges in approximately 50 minutes. If you have a larger property, consider upgrading to the 5.0Ah battery for roughly double the runtime at about 90 minutes per charge. The fast charging means that even with a single battery, you can cycle through charges efficiently. The battery is interchangeable with all EGO Power+ tools, which significantly increases its value if you standardize on the EGO platform for all your outdoor equipment.
Who Should Buy This Trimmer
This is the trimmer I recommend to most homeowners with medium to large yards who want a no-compromise cordless solution. The PowerLoad system alone justifies the investment if you have ever struggled with reloading string on a traditional spool head. Skip it only if you need maximum portability for a very large property where gas still makes sense, or if you are on a tight budget and want to spend under 100 dollars. For everyone else, this is the cordless trimmer to beat in 2026.
2. WORX WG163 12-Inch with Command Feed
WORX Cordless String Trimmer & Lawn Edger, 12" Electric Weed Wacker with Command Feed, 20V Weed Eater with 5.5 LBS, 2 Batteries & Charger Included, WG163
12-inch swath
Command Feed
90 degree tilt
Free spools for life
5.52 lbs
Pros
- Free spools for life saves money long-term
- Command Feed button dispenses line instantly
- 90 degree tilting head handles slopes
- Rubberized wheels for edging guidance
- Massive 28k review base with 4.3 star average
Cons
- Smaller 12-inch swath takes more passes
- 0.065 inch line is thinner than pro-grade
The WORX WG163 is the best selling string trimmer on Amazon for good reason. With nearly 28,000 reviews and a 4.3-star average rating, this trimmer has earned its reputation through years of reliable performance across thousands of real-world yards. I found it to be the smartest value pick in this entire roundup, offering features and accessories that competitors charge significantly more for.
The standout feature here is the free spools for life program. Most trimmer owners spend 15 to 30 dollars per year on replacement line, and over five years that adds up to 75 to 150 dollars in ongoing costs. WORX eliminates that expense entirely. You register your trimmer on their website, and whenever you need replacement spools, you pay only for shipping. Over the life of the trimmer, this savings effectively reduces your total cost of ownership below what you would pay for a cheaper trimmer plus its line replacements.
Command Feed works differently from bump-feed or fully automatic systems. Instead of tapping the head on the ground or waiting for the trimmer to sense that you need more line, you press a button on the handle. Line feeds out instantly and cleanly. I found this system more reliable than any bump-feed mechanism I have used, and it eliminates the jarring sensation of slamming the trimmer head into the ground every minute or two.
The 12-inch cutting swath is smaller than the EGO models, which means more passes to cover the same area. For small to medium yards, this is not a noticeable problem. For large properties, you will spend extra time completing your trimming route. The tradeoff for the smaller swath is a lighter overall weight of just 5.52 pounds, which makes this trimmer much easier to handle for extended periods.
The 90-degree tilting head is a feature I did not know I needed until I had it. Trimming along slopes, drainage ditches, and uneven terrain becomes much easier when you can angle the head rather than twisting your wrists into uncomfortable positions. The rubberized guide wheels help maintain a consistent cutting height when edging along sidewalks and driveways, producing clean lines without scalping the soil.
The adjustable spacer guard is a thoughtful detail that protects your flowers and garden plants from accidental contact with the trimmer line. I tested this feature extensively along a flower bed border, and the guard effectively prevented any damage to plants that were within an inch or two of the cutting area. The guard retracts when you do not need it, so it does not interfere with open-area trimming.
WORX Power Share battery compatibility is another strong selling point. The 20V batteries work across dozens of WORX tools, from drills and circular saws to blowers and hedge trimmers. If you already own WORX Power Share tools, this trimmer becomes an even better value since you can share batteries between devices and always have a charged backup ready.
The package includes two 20V Power Share maxLithium batteries and a charger. Having two batteries means you always have a backup, which effectively doubles your runtime. The batteries charge in about 3 hours each, so you can charge one while using the other. For homeowners with yards under a quarter acre, this dual-battery setup provides more than enough power to complete the job in one session.
Free Spools for Life Program Details
The program requires registering your trimmer on the WORX website within 30 days of purchase. Once enrolled, you order replacement spools as needed and pay only for shipping, typically around 8 dollars per order. The spools arrive pre-wound with 0.065-inch line and are compatible with the WG163 and several other WORX trimmer models. This program has been running for years and WORX continues to honor it, which speaks to the brand’s commitment to customer loyalty. I have seen forum posts from owners who have received dozens of free spools over the years without issue.
Ideal User Profile
This trimmer is perfect for homeowners with small to medium yards who want maximum value over the long haul. The free spools program and battery sharing make it incredibly cost-effective compared to alternatives that require ongoing line purchases. It is not ideal for heavy brush or commercial use, and the 0.065-inch line diameter limits its effectiveness against very thick weeds. For standard residential lawn maintenance including edge trimming, fence line cleanup, and garden bed borders, it is hard to beat the WG163 on value.
3. WORX WG170 3-in-1 Revolution Trimmer, Edger, and Mini Mower
WORX 3 in 1 Cordless String Trimmer/Lawn Edger/Mini Mower, 12" Electric Weed Wacker with Command Feed, 20V Weed Eater with 5.5 LBS, 2 Batteries & Charger Included, WG170
3-in-1 trimmer edger mower
12-inch
7600 RPM
2 batteries
5.5 lbs
Pros
- Converts to edger and mini mower for tight spaces
- 7 handle adjustments and 6 rotating head settings
- Includes 2 batteries and 3 trimmer spools
- Command Feed instant line system
Cons
- 5 hour charging time is notably slow
- Mini mower function works only on very small patches
The WORX WG170 takes everything good about the WG163 and adds a third function that actually proves useful. This 3-in-1 tool works as a string trimmer, an in-line edger, and a mini lawn mower. I was skeptical about the mini mower mode at first, since multi-function tools often compromise on each individual function. But the WG170 actually came in handy for a small strip of grass between my driveway and the property line where my full-size mower simply cannot reach.
In trimmer mode, the WG170 performs nearly identically to the WG163. The Command Feed system works the same way, with a push button on the handle that feeds line instantly without bumping or waiting. The 7600 RPM motor provides plenty of power for standard residential grass and light weeds. I noticed no significant performance difference between this model and the WG163 when trimming along fence lines and garden borders.
The conversion between modes is where this tool shines. Switching from trimmer to edger takes about 15 seconds with a simple shaft rotation and adjustment. Going to mini mower mode requires attaching the included support wheels and adjusting the head angle to horizontal. It is not something you do every minute, but it is quick enough for practical use during a typical yard maintenance session.
With 7 handle adjustments and 6 rotating head settings, I was able to find a comfortable configuration for my height and trimming style. This level of adjustability matters more than you might think. An uncomfortable trimmer leads to sloppy work and skipped areas, while a well-adjusted tool makes the job faster and more precise. Multiple household members of different heights can each find their preferred settings.
The package includes 2 batteries and 3 trimmer spools, which is generous at this price point. Having a backup battery means you can keep working while the second battery charges. The 3 included spools give you months of trimming before you need replacements, and the WG170 is also covered by the free spools for life program if you register it. Just be aware that the 5-hour charge time per battery is slower than competitors, so plan ahead if you have a larger yard.
At 5.5 pounds, this is one of the lightest trimmers in our roundup. That light weight makes it a great choice for anyone who experiences arm fatigue or needs to trim for extended periods. The tradeoff is that lighter weight means less momentum and inertia for cutting through thick weeds. For standard residential grass, this is a non-issue. For overgrown areas with woody stems, you may need to slow your pace.
The support wheels included for mini mower mode also double as edging guides when you are using the tool in edger configuration. I found these wheels helpful for maintaining straight lines along my driveway, though they do add a bit of bulk when you are using the tool as a standard trimmer. The wheels are easy to attach and remove with a simple clip mechanism.
Mini Mower Mode Limitations
The mini mower attachment works well on small, isolated patches of grass up to roughly 12 inches wide and a few feet long. It is not designed to replace your primary lawn mower for any significant area. Think of it as a precision tool for strips and patches that your main mower leaves behind, such as the strip between a driveway and sidewalk, or small isolated patches near garden borders. The support wheels maintain a consistent cutting height of about 1.5 inches, which is adequate for most warm-season grasses.
Best Use Cases for the 3-in-1 Design
This trimmer suits homeowners who value versatility and have limited storage space. Instead of owning a separate edger and trimmer, you get both in one tool plus a bonus mini mower function. It is especially appealing for townhouse owners, condo dwellers, apartment renters with small courtyard areas, or anyone with a small yard where multi-function tools make more sense than dedicated equipment. If storage space in your garage or shed is tight, the WG170 replaces two or three separate tools with one compact package.
4. BLACK+DECKER LST522 20V MAX 12-Inch with Dual Speed
BLACK+DECKER 20V MAX 12 Inch Weed Eater Cordless String Trimmer and Wheeled Edger Lawn Tool with Spool, 2.5Ah Battery and Charger Included, Lightweight, 2 Speed PowerDrive (LST522)
12-inch
20V MAX
Dual speed
AFS auto feed
5.7 lbs
Pros
- Dual speed control optimizes power or runtime
- AFS automatic line feed requires no bumping
- PowerDrive transmission boosts cutting torque
- Converts to wheeled edger in seconds
Cons
- Single battery included
- Low speed still drains battery faster than expected
BLACK+DECKER has been making dependable homeowner tools for decades, and the LST522 shows why they remain a trusted name in the outdoor power equipment space. This 20V MAX cordless trimmer earned the highest individual rating in our roundup at 4.5 stars across more than 6,400 reviews. I found it to be a reliable, no-surprises performer that does exactly what it promises without any gimmicks.
The standout feature for me was the dual speed control. Most trimmers in this price range offer a single speed setting, which means you are using full power even when you are trimming delicate grass along a flower bed. Having two speeds lets you conserve battery on light grass and crank up the power for thick patches. I ran on low speed for about 70 percent of my trimming route and only switched to high for the dense weeds along my back fence.
The AFS automatic feed system dispenses line without any bumping or button pressing. It senses when the line gets short from normal wear and breakage, and feeds more automatically as needed. In my testing, it worked reliably about 90 percent of the time. Occasionally I had to manually bump the head to get a fresh feed, but that was rare and never became a recurring problem during any single trimming session.
The PowerDrive transmission is a fancy name for a gear system that delivers more torque to the cutting head than a direct-drive design. Whatever you call it, the result is noticeable. This trimmer cuts through thicker grass than you would expect from a 20V tool. It is not going to match the EGO 56V system for raw power, but for the price point, the cutting performance impressed me across a range of grass types and conditions.
Converting from trimmer to wheeled edger takes about 10 seconds with a simple rotation of the shaft. The integrated wheel helps guide a straight line along sidewalks and driveways without requiring you to freehand the edge. I used the edger mode for about 100 feet of sidewalk edge during testing and was happy with the clean, consistent line it produced. The wheel also prevents the trimmer head from contacting concrete, which extends line life significantly.
The premium soft grip handle is more comfortable than the basic plastic handles found on some competitors. I trimmed for about 30 minutes without any hand cramping or discomfort. The adjustable height settings accommodate users of different heights, and the overall balance feels good even though the battery is mounted at the rear of the shaft.
My main complaint is that only one battery is included in the package. For a tool marketed toward homeowners who may not own other BLACK+DECKER 20V tools, having a single battery means downtime while it recharges after about 25 to 30 minutes of use. If you already own BLACK+DECKER 20V MAX tools like their drill or impact driver, the shared battery system makes this less of an issue since you likely have a spare battery already.
The extended runtime battery, which BLACK+DECKER claims delivers 66 percent more runtime than their standard battery, did seem to last longer than expected. I got approximately 30 to 35 minutes per charge during normal trimming, which is above average for a 2.5Ah 20V battery in this category. The PowerDrive transmission likely contributes to this efficiency by requiring fewer passes through thick grass.
Dual Speed Control Real-World Impact
In my testing, low speed delivered approximately 35 minutes of runtime while high speed reduced that to about 20 minutes. The difference in cutting power is most noticeable on grass taller than 6 inches or on dense weeds with woody stems. For typical weekly maintenance of a manicured lawn where you are trimming growth that is only a few days old, low speed handles everything comfortably and extends your battery life significantly. I recommend defaulting to low speed and only switching to high when you encounter resistance that slows the cutting head.
Battery Ecosystem and Upgrade Path
The included 2.5Ah battery works with all BLACK+DECKER 20V MAX tools, which is one of the largest budget tool ecosystems available on the market. The platform includes drills, impact drivers, circular saws, reciprocating saws, blowers, hedge trimmers, and other outdoor equipment. If you want longer runtime, the LBXR2520 extended battery provides roughly 66 percent more runtime per charge. The standard charger that comes with the LST522 charges a depleted battery in approximately 4 hours, which is slower than the EGO charger but adequate for overnight charging.
5. EGO Power+ ST1502SA 15-Inch with Rapid-Reload Head
EGO POWER+ String Trimmer, Battery Powered, 15" Trimmer for Weeds and Grass with Rapid Reload, Split Shaft, Includes 56V 2.5Ah Battery and Charger - ST1502SA
15-inch
Rapid-Reload head
Split shaft
50 min runtime
7.4 lbs
Pros
- Rapid-Reload head for quick manual line changes
- Split shaft design for easy storage
- 50 minutes of runtime per charge
- Variable speed and IPX4 weather resistance
- 5-year tool warranty
Cons
- Not as powerful as gas trimmers for heavy brush
- Split shaft feels slightly less rigid than one-piece
The EGO ST1502SA is the sibling to our top pick, and it offers a different approach to the line loading problem. Instead of the fully automatic PowerLoad system found on the ST1511T, this model uses a Rapid-Reload head that lets you manually reload line in about 30 seconds without taking the head apart. I tested both systems extensively and found them both effective, just designed for different user preferences and budgets.
At 7.4 pounds, this is significantly lighter than the ST1511T which weighs 10.27 pounds. That weight difference was immediately noticeable during extended trimming sessions. If arm fatigue is a concern for you, or if you have a larger property that requires 30-plus minutes of continuous trimming, the ST1502SA is the EGO model to get. The tradeoff is that the lighter weight means it does not feel quite as planted when you are pushing it through very thick growth.
The 50-minute runtime claim actually held up in my testing for light to medium trimming along edges and garden borders. When I encountered heavy weeds with thick stems, expect closer to 35 minutes of runtime. The 56V 2.5Ah battery recharges in about 50 minutes, which means you can cycle through batteries efficiently if you own multiples from the EGO platform. The fan-cooled charging system prevents overheating during repeated charge cycles, which extends overall battery lifespan.
The split shaft design is a feature I did not appreciate until I needed to store the trimmer in a crowded garage. The shaft separates into two pieces with a simple push-button mechanism. This makes storage and transport much easier, especially if you need to fit the trimmer in a car trunk for a vacation property or on a narrow storage shelf between other tools and equipment.
I noticed the split shaft introduces a very slight flex under heavy load compared to a one-piece design. It is not enough to affect cutting performance for normal residential use, but it is perceptible when you push the head into very dense vegetation. Professional users tackling thick brush might find this flex annoying. For homeowners doing standard weekly maintenance, the storage convenience far outweighs this minor tradeoff.
The variable speed control and IPX4 weather resistance are shared features with the ST1511T. Both are genuinely valuable in practice. Variable speed lets you balance cutting power against battery runtime depending on what you are trimming. The IPX4 weather resistance rating means you can safely trim after a light rain or in humid conditions without worrying about water damage to the motor or electronics.
The 15-inch cutting swath with dual feed spiral twist 0.095-inch line puts this trimmer in the same cutting performance class as the ST1511T. Both EGO models cut wider paths than the 12-inch WORX and BLACK+DECKER models, which means fewer passes and faster completion times on larger properties. The professional-grade line diameter also means fewer breaks and less frequent line replacement compared to the 0.065-inch line used by most budget trimmers.
Rapid-Reload vs PowerLoad Comparison
The Rapid-Reload head requires you to manually feed line through two eyelets and wind it onto the spool by hand. It takes about 30 seconds with practice, and the design makes it nearly impossible to cross-thread or tangle the line. PowerLoad on the ST1511T automates this process entirely with a motorized winding system. If you change line infrequently, perhaps once or twice per season, the Rapid-Reload system is perfectly adequate. If you trim heavily and find yourself reloading line every few weeks, the PowerLoad system on the ST1511T saves meaningful time and frustration.
Storage and Transport Advantages
The split shaft reduces the stored length from about 60 inches to roughly 30 inches per section. This makes it the most garage-friendly trimmer in our roundup, fitting easily on standard shelving or in a compact storage closet. The shaft connection uses a robust locking mechanism, and I noticed no wobble or play after repeated assembly and disassembly during testing. If you live in an apartment, condo, or townhouse with limited storage, this design consideration alone may justify choosing the ST1502SA over other options.
6. VARSK 12-Inch 20V Cordless with Automatic Line Feed
VARSK 12 Inch 20V Cordless Weed Wacker with Automatic Line Feed, 2 in 1 String Trimmer and Edger, Includes 2 X 2.0Ah Batteries/1 X Charger/6 X Replacement Spools, Weed Eater for Lawn, Garden, etc
12-inch
20V cordless
8700 RPM
2 batteries included
6.73 lbs
Pros
- Two 2.0Ah batteries included for extended runtime
- Automatic line feed requires no user intervention
- 8700 RPM motor speed is class-leading
- Includes 6 bonus replacement spools
- 180 degree adjustable handle
Cons
- Requires assembly out of the box
- Lesser known brand with shorter warranty period
The VARSK 12-inch cordless trimmer surprised me in ways I did not expect. I went into testing with low expectations since VARSK is a lesser-known brand compared to EGO, WORX, and BLACK+DECKER. But it held its own against those more established names in nearly every category. With over 5,500 reviews and a 4.4-star average, clearly other homeowners have discovered what I found, which is that this trimmer punches well above its weight class.
The biggest selling point right out of the box is the inclusion of two 2.0Ah batteries and six replacement spools. Most competitors at this price point include one battery and zero spare spools. Having a second battery means you can work continuously without waiting for a recharge, since one battery charges while you use the other. The six replacement spools provide months of trimming before you need to buy more line.
The 8700 RPM motor speed is actually the highest in our entire roundup, beating the WORX models at 7600 RPM and the EGO at 5800 RPM. In practice, higher RPM means the line tip moves faster, which translates to cleaner cuts through grass stems. I noticed the VARSK produced visibly cleaner cut edges compared to the BLACK+DECKER models, which run at lower RPMs. The cleaner cuts are not just cosmetic. They are healthier for your grass, since ragged cuts invite disease and pest problems.
The automatic line feed system worked well during my testing. It dispenses line without bumping or button pressing, sensing when the line gets short from normal wear. I did experience one jam during about two hours of total use, which I cleared by opening the head and rethreading the line. Not ideal, but not a dealbreaker at this price point. The auto-feed was reliable enough that I rarely thought about it during normal trimming.
The 2-in-1 design converts between trimmer and edger with a 90-degree head rotation. The pivoting head offers 80 degrees of adjustment, which I used for trimming along a sloped garden bed where a fixed-angle head would have been awkward. The 180-degree adjustable handle accommodates different grip preferences and user heights, making this trimmer adaptable to a wide range of users.
Assembly is required out of the box, which took me about 15 minutes using the included instructions. The process involves attaching the shaft sections, installing the handle, and attaching the debris guard. The instructions were clear enough with illustrated diagrams, but if you are not comfortable with basic tool assembly, this might be a drawback. Once assembled, the trimmer felt solid and well-constructed for its price range.
The inclusion of a fast charger means you can replenish a depleted battery in about 90 minutes, which is faster than the WORX charger at 3 hours. With two batteries and a 90-minute charge time, you can effectively trim continuously by swapping batteries as needed. This is a significant practical advantage over single-battery competitors that leave you waiting during recharge cycles.
Battery Performance and Charging
Each 2.0Ah battery delivers approximately 30 minutes of runtime under normal trimming conditions along edges and garden borders. With heavy weeds, expect closer to 20 minutes per battery. With two batteries, you get about an hour of total trimming time, which covers most residential yards. The included charger replenishes a battery in roughly 90 minutes. The batteries are VARSK-specific and not compatible with other tool brands, which is a limitation compared to the shared battery platforms offered by WORX, BLACK+DECKER, and EGO.
Value Proposition Analysis
When you factor in the two batteries, six spare spools, and the charger, the VARSK offers the most complete package in our roundup relative to its price. The main risk is brand longevity, as VARSK is a newer name in outdoor power equipment with a shorter track record than established brands. The one-year warranty is shorter than the two to five year warranties offered by competitors. If you are willing to accept the brand risk in exchange for a more complete accessory package, the VARSK delivers excellent value for budget-conscious buyers.

If you have a small yard with access to an outdoor outlet, this may be all the trimmer you will ever need. I was genuinely impressed by how capable this budget option proved to be during testing.
The biggest advantage of corded power is unlimited runtime. There is no battery to charge, no gas to mix, and no gradual power degradation as the energy source runs down. You get full 6.5-amp power from start to finish, every single time, for as long as you want to trim. For homeowners who are tired of battery anxiety or who simply want a dependable tool that always works when they pick it up, corded tools are hard to argue against.
The 14-inch cutting swath is the second widest in our roundup, behind only the gas-powered Husqvarna at 17 inches. That wider coverage means fewer passes to trim the same area compared to the 12-inch WORX and BLACK+DECKER cordless models. I found the cutting width more than adequate for standard residential edge trimming, fence line cleanup, and garden bed maintenance.
EasyFeed is BLACK+DECKER’s push-button line advancement system, and it is one of the best features on this trimmer. Press a button on the handle and line feeds out smoothly. No bumping required. I tested this system extensively across multiple trimming sessions and it worked flawlessly every time. The system is simple, reliable, and eliminates the most common complaint about budget trimmers, which is finicky line feed mechanisms.
The 6.5-amp motor with POWERDRIVE Transmission delivers more cutting torque than you might expect from such a lightweight tool. The POWERDRIVE system uses a geared transmission to multiply the motor’s torque at the cutting head. In practice, this means the BESTE620 cuts through thicker grass than other budget trimmers that use a direct-drive design. It will not tackle woody brush, but for normal residential grass and weeds, the power is more than sufficient.
At 5.3 pounds, this is the lightest trimmer in our roundup by a significant margin. The difference between 5.3 pounds and the 10-plus pound EGO and Husqvarna models is dramatic and immediately noticeable. If you have any arm or shoulder issues, or if you simply want to minimize fatigue during trimming, this lightweight design makes the job much more comfortable. I was able to trim for 40 minutes without any discomfort.
The 2-in-1 design includes a wheeled edge guide for converting to edger mode. The adjustable handle and multiple height positions accommodate users of different heights and arm lengths. The cord retention system is a thoughtful detail that prevents the extension cord from accidentally disconnecting mid-trim, which is a common frustration with corded tools that lack this feature.
Corded Trimmer Limitations and Workarounds
The main limitation is range. You are tethered to an electrical outlet, which means you need a suitable outdoor-rated extension cord to reach all areas of your yard. For most small to medium yards, a 100-foot 14-gauge extension cord provides adequate reach without significant voltage drop. The cord does take some getting used to, as you need to manage it while trimming to avoid cutting it with the trimmer line or tangling it around obstacles. The tradeoff of unlimited runtime and consistent power is worth it for many homeowners, especially those with smaller properties.
Extension Cord Requirements
BLACK+DECKER recommends a minimum 14-gauge extension cord for runs up to 50 feet and a 12-gauge cord for runs up to 100 feet. Using an undersized cord causes voltage drop that reduces cutting power and can damage the motor over time. Budget an additional 25 to 40 dollars for a quality outdoor extension cord if you do not already own one. Look for cords rated for outdoor use with a W designation on the jacket, and avoid indoor-only cords which can degrade or short-circuit when exposed to moisture.

17-inch
22cc 2-cycle gas
SmartStart
T25 head
10.58 lbs
Pros
- 17-inch cutting swath covers maximum area per pass
- SmartStart system for reliable pull-starting
- Straight shaft reaches under bushes and obstacles
- Compatible with Husqvarna attachment system
- Gas power means unlimited runtime
Cons
- Requires fuel mixing and regular engine maintenance
- Louder and heavier than electric alternatives
The Husqvarna 122LK is the only gas-powered trimmer in our roundup, and it earns its place for specific use cases where electric tools still fall short. The 22cc 2-cycle engine delivers consistent power that does not fade as the session goes on, making it ideal for large properties and heavy brush where battery tools would require multiple battery swaps or simply lack the torque to cut effectively.
The 17-inch cutting swath is the widest in our lineup by a significant margin. Each pass covers 42 percent more ground than the 12-inch electric models from WORX and BLACK+DECKER. On my test property, I trimmed the same fence line in about 40 percent less time compared to the 12-inch models. That width advantage adds up quickly on large properties, transforming an hour-long job into a 35-minute task.
Husqvarna’s SmartStart system addresses the most common complaint about gas trimmers, which is the difficulty of starting them. The engine and starter have been designed so the machine starts quickly with minimum effort, reducing resistance in the starter cord by approximately 40 percent compared to conventional designs. I was able to start the 122LK within 2 to 3 pulls every time during testing, which is a dramatic improvement over older gas trimmers that could take 10 or more pulls when cold.
The straight shaft design lets you reach underneath bushes, decks, fences, and low-hanging branches that curved shaft trimmers simply cannot access. This matters more than you might expect if you have dense landscaping with lots of obstacles. Professional landscapers strongly prefer straight shafts for exactly this reason, and it is the standard design for all commercial-grade trimmers.
The T25 string trimmer head is Husqvarna’s proven tapping head that feeds line when you bump it against the ground. It is a simple, reliable system that has been refined over decades of professional use. The T25 head is easy to open for line reloading, and it accepts a wide range of line diameters from 0.080 to 0.105 inches. Reloading line requires removing the head cap and winding manually, which takes about 5 minutes with practice.
Compatibility with Husqvarna’s attachment system turns this trimmer into a multi-tool platform. You can swap the trimming head for a brush cutter blade, pole saw, edger, tiller, or other attachments from the Husqvarna range. If you want one power head that handles multiple yard tasks throughout the seasons, this capability adds significant value and reduces the total number of engines you need to maintain.
The 122LK runs at approximately 7200 RPM, which combined with the 17-inch swath and the ability to use thick 0.105-inch line, makes it the most capable trimmer in our roundup for cutting through heavy vegetation. It handles woody brush, thick weeds, and overgrown areas that would stall any of the battery-powered models. The tradeoffs are noise, weight at 10.58 pounds, and the ongoing maintenance requirements of a gas engine.
Fuel Mixing and Maintenance Requirements
The 22cc 2-cycle engine requires a 50:1 fuel-to-oil mixture, which means 2.6 ounces of high-quality 2-cycle oil per gallon of unleaded gasoline. Husqvarna sells pre-mixed fuel in cans that eliminates the measuring step entirely, and many users prefer this option for its convenience and long shelf life. Regular maintenance includes cleaning or replacing the air filter every few months depending on usage, replacing the spark plug annually, cleaning the muffler spark arrestor screen, and occasionally cleaning or replacing the fuel filter. While more involved than battery tools, the maintenance is straightforward and well-documented in the included manual.
When Gas Still Makes Sense Over Battery
Gas power remains the best choice for properties over one acre, areas without reliable power outlets for battery charging, and heavy brush clearing tasks. The tradeoffs are noise during operation, exhaust emissions, the ongoing cost of fuel and oil, and more complex maintenance. If your trimming needs fall within typical suburban yard maintenance on a property under an acre, any of the battery or corded models in this roundup will serve you better with significantly less hassle. The Husqvarna is the right choice when you need maximum cutting power, unlimited runtime, and the ability to reach remote areas of a large property without worrying about battery life or cord length.
Buying Guide: How to Choose the Best String Trimmer in 2026?
Choosing the right string trimmer comes down to understanding your yard size, your budget, and your tolerance for maintenance. I have broken down the key factors that should drive your decision, based on hundreds of hours of testing and the real-world feedback from homeowner forums and professional landscaper communities. Read through these sections to identify which factors matter most for your specific situation.
Power Source: Corded, Cordless, or Gas
The power source is your first and most important decision. Each type has distinct advantages and limitations that determine the type of user it suits best. Getting this decision right narrows your options significantly and prevents you from buying a trimmer that does not match your needs.
Corded electric trimmers like the BLACK+DECKER BESTE620 offer unlimited runtime and the lowest cost of any option. They are perfect for small yards with nearby outdoor outlets, typically under a quarter acre. The tradeoff is that you are tethered to a cord, which limits your range and requires managing the cord as you work around trees, garden beds, and other obstacles. For townhomes, small city lots, and condo patios, corded trimmers are often the most practical choice because they deliver consistent power with zero maintenance.
Cordless battery trimmers dominate our roundup because they offer the best balance of convenience and power for most homeowners. Modern lithium-ion batteries deliver 30 to 50 minutes of runtime on a single charge, which covers most residential yards. The main considerations are battery life under real-world conditions, charge time, and whether the battery is compatible with other tools you own or plan to buy. Battery platforms from EGO at 56V, WORX at 20V Power Share, and BLACK+DECKER at 20V MAX each include dozens of tools that share batteries across a single platform.
Gas trimmers remain relevant for large properties and heavy-duty use where electric tools cannot match the required runtime or cutting power. They deliver consistent power without battery anxiety and can run as long as you have fuel. The tradeoffs are noise during operation, emissions, maintenance requirements including fuel mixing and filter cleaning, and the hassle of storing fuel safely. For properties over an acre or situations involving heavy brush clearing on a regular basis, gas is still the most reliable and capable option available.
Cutting Swath and Line Diameter
The cutting swath is the width of grass the trimmer cuts in a single pass. Wider swaths mean fewer passes and faster completion times. In our roundup, swaths range from 12 inches on the WORX and BLACK+DECKER cordless models to 17 inches on the Husqvarna gas trimmer. The EGO models sit in the middle at 15 inches.
For small to medium yards, a 12 to 14-inch swath is perfectly adequate. You will spend a few extra minutes compared to a wider trimmer, but the lighter weight and lower cost of narrower models often outweigh the time savings. For larger properties or if you simply want to finish your trimming as quickly as possible, the 15-inch EGO models or the 17-inch Husqvarna will save significant time per session. The tradeoff with wider swaths is that they require more motor power and drain batteries faster than narrower configurations.
Line diameter affects both cutting performance and line durability. Most homeowner trimmers use 0.065-inch line, which is adequate for standard residential grass and light weeds. Professional-grade trimmers like the EGO models use 0.095-inch line that handles heavier growth and breaks much less frequently during normal use. The Husqvarna can handle up to 0.105-inch line for serious brush cutting and heavy-duty applications. Thicker line costs more per foot but lasts significantly longer between replacements.
Line quality matters as much as diameter, if not more. Cheap generic line becomes brittle and breaks constantly, which is one of the most common complaints on homeowner forums. Investing in quality line from brands like Echo (Black Diamond line), Oregon, or Husqvarna significantly reduces frustration and replacement frequency. Quality line also produces cleaner cuts, which is healthier for your grass.
Battery Runtime and Charging Considerations
Battery runtime claims from manufacturers tend to be optimistic. Real-world runtime depends on grass thickness, cutting speed setting, line diameter, how much line you are feeding, and whether you are trimming wet or dry grass. In my testing, I consistently got 20 to 30 percent less runtime than advertised when trimming thick grass compared to the manufacturer claims measured under ideal conditions.
For yards under a quarter acre, a single 2.0Ah to 2.5Ah battery typically provides enough runtime to complete the job in one session. For larger properties between a quarter acre and a half acre, consider models that include two batteries or plan to purchase a spare battery. The EGO platform’s fast charging, roughly 50 minutes for the 2.5Ah battery, makes cycling between batteries practical even with a single charger.
Battery platform compatibility is a critical long-term consideration that many buyers overlook. When you buy a cordless trimmer, you are effectively buying into that brand’s battery ecosystem for all future tool purchases. EGO’s 56V platform, WORX’s 20V Power Share system, and BLACK+DECKER’s 20V MAX line each include mowers, blowers, hedge trimmers, chainsaws, and other outdoor tools. Choosing a platform you can grow into saves money over time because additional tools can be purchased as bare tools without batteries.
Battery lifespan is another consideration. Lithium-ion batteries typically last 3 to 5 years before noticeable capacity degradation, depending on usage patterns and charging habits. Storing batteries at moderate temperatures rather than extreme heat or cold extends their life. Avoiding complete discharges and storing batteries at 40 to 60 percent charge during off-seasons also helps preserve long-term capacity.
Weight, Balance, and Ergonomics
Weight directly affects how long you can trim comfortably before fatigue sets in. The lightest trimmer in our roundup is the BLACK+DECKER BESTE620 at 5.3 pounds, while the heaviest is the Husqvarna at 10.58 pounds. That difference is immediately noticeable and becomes more pronounced the longer you work. As a general rule, every additional pound of weight reduces comfortable trimming time by roughly 5 to 10 minutes.
Balance matters as much as raw weight. A well-balanced trimmer feels lighter than a poorly balanced one of the same weight, because the weight distribution reduces the torque your wrists and forearms must counteract. The EGO ST1511T at 10.27 pounds feels manageable because the battery weight at the rear of the shaft counterbalances the motor at the cutting head. Some budget trimmers put nearly all the weight at the head end, which creates fatigue-inducing torque on your wrists even if the total weight is modest.
Adjustable handles and telescoping shafts accommodate different user heights and arm lengths. I am approximately 5 foot 10 and found all the trimmers in our roundup usable at their default settings, but shorter or taller users should pay close attention to shaft adjustability. The EGO models and the WORX WG170 offer the most adjustment range in our lineup. A telescoping shaft that can be shortened for storage is also valuable if garage space is limited.
Vibration control is an often-overlookored comfort factor. Gas trimmers produce the most vibration, which can cause numbness and tingling in your hands during extended use. Battery-powered trimmers with brushless motors produce significantly less vibration. The EGO models in particular feel smooth and controlled during operation, with minimal hand vibration even at high speed settings.
Line Loading Systems Explained
Line loading is the single most frustrating part of string trimmer ownership based on my analysis of forum discussions and owner reviews. Every manufacturer has tried to solve this problem differently, with varying degrees of success. Understanding the different systems helps you choose one that matches your patience level and technical comfort.
Bump feed systems require you to tap the trimmer head against the ground to release more line. This is the oldest and most common system, and it is what the Husqvarna T25 head uses. It works reliably in grass and soft soil but can be frustrating when the mechanism sticks or when you are trimming over hard surfaces like concrete where bumping is impractical or damages the head.
Automatic feed systems sense when line is getting short and feed more without any user intervention. The BLACK+DECKER AFS system and the VARSK auto-feed system both use this approach. In my testing, they worked reliably about 90 percent of the time. These systems are convenient because you never have to think about line management, but they add mechanical complexity that can fail.
Push-button feed systems let you dispense line with a deliberate button press on the handle. The WORX Command Feed and BLACK+DECKER EasyFeed systems both use this approach. I found these to be the most reliable and user-friendly systems for homeowners. You control exactly when and how much line feeds out, which prevents waste and ensures you always have sufficient line for the task at hand.
The EGO PowerLoad system is in a category of its own and represents the current state of the art in line management. It automates the line winding process entirely, eliminating the need to manually wind line onto the spool. For users who find line loading intimidating or who have struggled with traditional spool systems in the past, this feature alone justifies the EGO’s higher price point compared to budget alternatives.
Attachment-Capable vs Dedicated Trimmers
Attachment-capable trimmers accept different tool heads, turning one power shaft into a multi-tool platform that can handle trimming, edging, pruning, and tilling. The Husqvarna 122LK supports this capability with compatible brush cutter, pole saw, edger, and tiller attachments from Husqvarna’s attachment lineup. This versatility can save money and storage space compared to buying dedicated tools for each task.
The tradeoff is that attachment-capable trimmers are typically heavier than dedicated trimmers and may not trim quite as well as a purpose-built tool at the same price point. The attachment coupling adds weight to the shaft and creates a slight flex point. If you only need a trimmer and have no interest in other attachments, a dedicated trimmer offers better value and performance per dollar.
I recommend attachment-capable trimmers for homeowners who value versatility and have storage constraints. If you need a trimmer, an edger, and a pole pruner, buying one power head and three attachments is more economical than three separate tools with their own motors. The Husqvarna attachment system is particularly well-regarded for its build quality and the range of available attachments.
Brand Reliability and Warranty Considerations
Brand reputation matters for long-term satisfaction and warranty support. Based on forum discussions and long-term owner reports, EGO leads the cordless market for build quality and customer support. The 5-year tool warranty and 3-year battery warranty on EGO products are among the best in the cordless industry. EGO’s customer service is frequently praised on homeowner forums for responsiveness and willingness to replace defective components.
Husqvarna has decades of reputation in gas-powered outdoor equipment. Professional landscapers consistently name Husqvarna, Stihl, and Echo as the most reliable gas trimmer brands based on years of daily commercial use. The 2-year consumer warranty on the 122LK extends to 5 years with qualifying Husqvarna fuel purchases, which is a nice bonus for owners who use the brand’s pre-mixed fuel.
WORX and BLACK+DECKER occupy the value segment with 2-year to 3-year warranties that are standard for their price tier. Their build quality is adequate for regular homeowner use, and their battery platforms are well-supported with widespread retail availability of replacement parts and accessories. WORX’s free spools for life program is a unique value-add that no other brand in this roundup matches.
