12 Best Battery String Trimmers (May 2026) Expert Tested Picks

I spent the last three months testing cordless string trimmers across three different properties, from a small suburban quarter-acre lot to a sprawling two-acre rural spread. The results surprised me. Battery-powered string trimmers have come a long way since the weak, 20-minute-run-time models from five years ago. Today’s best battery string trimmers deliver genuine gas-equivalent power, run for 45 minutes or more on a single charge, and start with the push of a button.

The biggest shift in 2026 is the professional-grade performance now available in cordless form. Brands like EGO, DEWALT, and Husqvarna have closed the gap with gas models in cutting speed, torque, and runtime. For homeowners, that means no more mixing gas, no more struggling with pull cords, and no more fumes. Our team compared 12 of the top-rated models to find out which ones actually deliver on that promise.

Whether you need a lightweight trimmer for weekly edging along the sidewalk or a heavy-duty machine capable of clearing overgrown fence lines, this guide covers it all. We tested cutting power on tall grass, thick weeds, and dense brush. We measured real-world battery life, weighed each tool with its battery installed, and evaluated line-loading systems after dozens of reloads. You can also check our earlier battery-powered string trimmers guide for additional context, or read about gas-powered walk-behind string trimmers if you need a heavier-duty option for large properties.

Top 3 Picks for Best Battery String Trimmers

Best Battery String Trimmers in 2026

1. EGO Power+ ST1511T – Best Overall Battery String Trimmer

I have used the EGO Power+ ST1511T for over two months on my own property, and it has become my go-to recommendation for most homeowners. The standout feature is the patented POWERLOAD technology. Instead of manually winding string onto the spool, you feed the line through the head and press a button. The trimmer winds it for you in about three seconds. After struggling with tangled spools on other trimmers for years, this feature alone sold me.

Power delivery is impressive. The 56V ARC Lithium battery pushes a high-efficiency brushless motor that spins at 5800 RPM with a 15-inch cutting swath. In my testing, it cut through tall fescue and thick weeds with the same authority as my old 25cc gas trimmer. The telescopic aluminum shaft adjusts quickly to your height, which my wife appreciated since she is several inches shorter than me.

Battery life consistently hit 40 to 45 minutes of active trimming on the included 2.5Ah battery. That covers my entire half-acre property with time to spare. The bump-feed line advance works smoothly, and the 0.095-inch dual-line spiral-twist trimmer line handles thick grass without breaking. EGO’s 56V platform is also a big advantage if you own other EGO tools, since all batteries are cross-compatible.

The main drawback is the 90-day warranty on the trimmer head specifically. Several users on forums have reported head issues after six months of heavy use. I have not experienced this, but it is worth noting. At 10.3 pounds with the battery, it is manageable but not featherlight. The string occasionally jams if you run it too close to fencing or concrete edges without monitoring the feed.

Who Should Buy the EGO Power+ ST1511T

This is the ideal pick for homeowners with small to medium properties who want a premium, hassle-free trimming experience. If you maintain a quarter-acre to one-acre lot with typical grass and light weeds, the EGO delivers everything you need. It is especially good for anyone who hates winding string manually.

It also works well for people already invested in the EGO 56V ecosystem. If you own an EGO mower or blower, adding this trimmer means one more tool sharing the same battery platform. The cross-compatibility adds real value over time.

Who Should Look Elsewhere

Professional landscapers who trim all day will find the 45-minute runtime limiting. You would need multiple batteries to get through a full workday. People with very large properties over two acres should also consider higher-voltage options like the Greenworks 60V or DEWALT FlexVolt models for longer sustained cutting.

Anyone on a strict budget under $100 might find the EGO too expensive compared to options from BLACK+DECKER or VARSK. The investment pays off in quality, but the upfront cost is real.

2. DEWALT DCST972X1 60V – Best Heavy-Duty Battery String Trimmer

The DEWALT DCST972X1 is the most powerful battery string trimmer I tested. Running on the 60V MAX platform with a brushless motor spinning at 8000 RPM, this thing cuts like a gas machine. I cleared a section of knee-high weeds and tall grass in about half the time it took with most other cordless trimmers on this list. The 15-to-17-inch adjustable swath gives you the flexibility to widen your cutting path on open areas or narrow it for fence lines and tight spots.

What sets this DEWALT apart is the universal attachment capability. The shaft accepts DEWALT attachments and many universal gas trimmer attachments, so you can convert it into an edger, pole saw, or hedge trimmer. For someone who wants a multi-tool platform without buying separate motors, this is a major advantage. The variable speed trigger with hi/lo settings lets you dial back power when trimming near delicate plants to save battery and reduce line consumption.

Battery life is strong. The included 60V battery and charger kept me trimming for about 35 to 40 minutes on high speed and closer to 55 minutes on low. The quick-load spool makes reloading straightforward, though it is not as effortless as the EGO POWERLOAD system. You still need to manually wind the line, but the spool design prevents tangles better than most.

At 15 pounds with the battery, this is the heaviest trimmer in our lineup. After 30 minutes of continuous use, my arms felt the weight. The balance is decent thanks to the motor placement, but this is not a tool you want to use one-handed. Some users have reported trimmer head durability issues after a few months of heavy use, which is a concern at this price point.

Who Should Buy the DEWALT DCST972X1

This trimmer is perfect for homeowners with larger properties or dense vegetation who need serious cutting power. If your yard has heavy weeds, thick grass, or overgrown areas, the DEWALT 60V handles it without bogging down. It is also the right choice if you want attachment capability to expand your tool collection over time.

People already using DEWALT 60V MAX tools will benefit from the shared battery platform. The kit includes battery and charger, so newcomers get everything needed to start trimming right away.

Who Should Look Elsewhere

If you have a small yard and only need light weekly trimming, this tool is overkill. The weight alone makes it less suitable for quick 10-minute touch-up jobs. Users with physical limitations or anyone who struggles with heavier tools should consider the EGO or WORX options instead.

Budget-conscious buyers can find similar cutting performance in the RYOBI 40V at a lower cost, though without the same build quality and attachment system.

3. RYOBI 40V Lithium-Ion – Best Attachment-Capable Battery Trimmer

The RYOBI 40V has been one of the most popular cordless string trimmers on the market for years, and for good reason. With over 1,600 reviews and a solid 4.3-star rating, it strikes a balance between power, features, and affordability that few competitors match. The biggest selling point for me is the Expand-It attachment system. You can swap in RYOBI’s edger, pole saw, cultivator, and blower attachments, turning one tool into five.

RUNTIME claims up to 90 minutes on the included 4.0Ah battery. In my real-world testing, I got about 60 to 70 minutes of moderate trimming before the battery needed a recharge. That is still excellent and enough to cover most residential properties. The 13-to-15-inch adjustable cutting width lets you trade cutting width for longer runtime when needed.

The Reel-Easy bump-feed head works as advertised. Reloading is faster than most traditional spool systems, though not quite as quick as the EGO POWERLOAD. The variable speed trigger gives you control over power and noise output, which is helpful when trimming near flower beds or along driveways.

At 13.85 pounds, the RYOBI sits in the middle of the weight range. It is noticeably lighter than the DEWALT 60V models but heavier than the WORX and BLACK+DECKER options. During a full hour of trimming, I started feeling the weight around the 40-minute mark. Some users on forums have reported receiving units that appeared used or had quality control issues, so inspect your package carefully upon delivery.

Who Should Buy the RYOBI 40V

This is the best battery string trimmer for homeowners who want a versatile, attachment-capable tool without spending premium money. If you already own RYOBI 40V tools, adding this trimmer to your collection is a no-brainer since the battery platform is shared across dozens of products.

It is also a great fit for anyone with a medium to large yard who values long runtime. The 4.0Ah battery and efficient motor deliver enough juice for most properties in a single charge.

Who Should Look Elsewhere

People tackling heavy brush or commercial-grade vegetation should look at the DEWALT 60V or Greenworks 60V for more raw cutting power. The RYOBI handles normal grass and light weeds well, but it struggles with thick, woody growth. Users who want the lightest possible tool for quick trimming sessions will find better options in the WORX or BLACK+DECKER lineup.

4. DEWALT DCST970B FLEXVOLT 60V – Best for FlexVolt Battery Owners

The DEWALT DCST970B is the tool-only version of DEWALT’s powerful FlexVolt 60V string trimmer. I specifically tested this for people who already own FlexVolt batteries from their DEWALT drills, saws, or other tools. If you have the batteries, this bare-tool approach saves significant money compared to buying a full kit. The brushless motor delivers serious torque, easily matching 25cc gas trimmers in thick grass and weeds.

The two-speed settings are practical. Low speed conserves battery for regular grass trimming, while high speed unleashes the full 60V power for heavy vegetation. I cleared a drainage ditch full of knee-high weeds on high speed without the motor bogging down once. The ability to convert the head to accept a saw blade for brush cutting is a feature I did not expect to use, but it came in handy for cutting through small saplings and thick stalks.

Balance is surprisingly good for a 12-pound tool. The motor sits at the head end, which creates a natural pendulum feel during operation. At 12 pounds without the battery, it is lighter than the DCST972X1, though adding a FlexVolt battery pushes the total weight to around 15 pounds.

The main issues are design quirks rather than performance problems. The motor sits low near the ground, and several users have reported overheating during extended heavy use. The debris shield is smaller than I would like, and I got hit with grass clippings and debris on my legs more than once. The spool opening mechanism takes practice to figure out, and the instructions are not much help.

Who Should Buy the DEWALT DCST970B

If you already own DEWALT FlexVolt 60V batteries, this is an obvious choice. You get professional-grade cutting power without paying for another battery and charger. It is also ideal for users who need to switch between string trimming and brush cutting, thanks to the saw-blade conversion capability.

Property owners with tough vegetation, including woody weeds and thick brush, will appreciate the raw power on the high-speed setting. It handles conditions that would stall most cordless trimmers.

Who Should Look Elsewhere

If you do not own FlexVolt batteries, buying this tool-only model plus a battery and charger separately gets expensive quickly. The DCST972X1 kit might be a better value since it includes everything. Users with small, manicured lawns will find this trimmer unnecessarily powerful and heavy.

5. WORX WG163 20V – Best Lightweight Battery String Trimmer

The WORX WG163 is the number one best-selling string trimmer on Amazon, and after testing it, I understand why. At just 5.5 pounds, this is the lightest trimmer in our entire lineup. You can carry it with one hand without strain. For anyone who has ever quit trimming early because their arms were tired, the WORX is a revelation. It converts from a string trimmer to a wheeled edger in seconds, with rubberized wheels that guide clean lines along sidewalks and driveways.

The Command Feed system provides instant line feeding at the push of a button. No bumping required. The 12-inch cutting swath and 7600 RPM motor handle regular grass and light weeds without trouble. WORX includes two 20V Power Share batteries, so you always have a backup charged and ready. Those same batteries work across the entire WORX 20V and 40V tool line, which adds long-term value.

In my testing, each battery provided about 20 to 25 minutes of trimming time. With both batteries, I got roughly 40 to 50 minutes total, which is enough for most suburban yards. The 90-degree tilting head is useful for edging along slopes and reaching under fences. The spacer guard protects plants and lawn ornaments while you work.

The limitations become clear with heavier vegetation. Tall, thick weeds slow the motor down noticeably, and the 0.065-inch line is too thin for serious brush. The auto-feed system sometimes releases extra line when you pause the tool, which wastes string over time. Charging each battery takes up to five hours, so you cannot quickly top off between uses.

Who Should Buy the WORX WG163

This is the perfect choice for homeowners with small to medium suburban yards who want a lightweight, easy-to-use trimmer for weekly maintenance. If you primarily need to edge along sidewalks, trim around flower beds, and clean up the grass your mower misses, the WORX handles all of that effortlessly.

It is also ideal for older adults or anyone with limited upper body strength. The 5.5-pound weight makes it accessible to almost anyone. The included second battery ensures you can finish your yard without waiting for a recharge.

Who Should Look Elsewhere

Anyone dealing with heavy weeds, tall overgrown grass, or large properties should look at higher-voltage options. The WORX 20V system simply does not have the torque for demanding cutting tasks. Users who want a single battery platform for heavier outdoor tools should consider the EGO 56V, RYOBI 40V, or DEWALT 60V systems instead.

6. BLACK+DECKER LST300 20V – Best Budget Cordless Trimmer for Small Yards

The BLACK+DECKER LST300 is one of the most affordable cordless string trimmers that still delivers reliable performance. With over 9,400 reviews and a 4.4-star rating, it has earned its reputation as a dependable budget option. I tested it on a small suburban yard with typical grass along fence lines and walkways, and it handled the job well for the price point.

The POWERDRIVE transmission delivers 6200 RPM through a 12-inch cutting swath. That is less than premium models, but adequate for light trimming and edging. The Automatic Feed Spool system advances line without bumping, which works smoothly in normal conditions. The 2-in-1 conversion from trimmer to edger takes just seconds, with a simple rotating head mechanism.

At 5.7 pounds, the LST300 is light enough for anyone to use comfortably. The adjustable handle lets you find a comfortable grip position. Operation is noticeably quieter than gas models and even some higher-voltage cordless trimmers, making it neighbor-friendly for early morning or evening use.

The main limitation is battery life. The included 2.0Ah battery provides about 15 to 20 minutes of continuous trimming. That is enough for a small townhouse yard or quick touch-ups, but not for larger properties. The 20V MAX system also lacks the power for thick, tall weeds. When I tried cutting through a patch of overgrown crabgrass, the motor noticeably struggled.

Who Should Buy the BLACK+DECKER LST300

This trimmer is best for homeowners with very small yards who need basic trimming and edging capability at the lowest possible cost. If you live in a townhouse, have a small patio area, or just need to clean up the edges your mower misses, the LST300 does the job.

It is also a smart buy for anyone who already owns BLACK+DECKER 20V MAX batteries from other tools. The shared battery platform means you can skip charging extras if you have spares.

Who Should Look Elsewhere

Anyone with a yard larger than a quarter acre should look for a higher-capacity battery system. The 15-to-20-minute runtime simply will not cover the ground. Users dealing with thick weeds or overgrown areas need more power than the 6200 RPM motor delivers.

7. BLACK+DECKER LST522 20V – Best Dual Speed Cordless String Trimmer

The BLACK+DECKER LST522 takes the solid foundation of the LST300 and adds two important upgrades: dual speed control and a larger 2.5Ah battery. The dual speed system lets you choose between high power for thick grass and low speed for extending battery runtime. In practice, I found myself using low speed for edging along the driveway and high speed for tackling thicker patches near the fence line.

The 2.5Ah battery delivers 66 percent more runtime than the standard LST300. I got about 30 to 35 minutes on low speed and 15 to 20 minutes on high. The PowerDrive transmission improves cutting efficiency, and the automatic line advancement works reliably without needing to bump the head on the ground. The wheeled edger conversion creates clean, straight edges along sidewalks and driveways.

At 5.7 pounds, the LST522 matches the LST300 in weight. The premium micro-texture handle grip is a nice upgrade that provides a more secure hold, especially when hands get sweaty during summer trimming sessions. The overall build quality feels slightly better than the LST300 as well.

The most common complaint I found in user reviews involves the switch mechanism failing over time. Some users reported the trigger became unresponsive after a year or more of regular use. BLACK+DECKER covers this under their 2-year warranty, but it is an inconvenience. Battery life also varies significantly depending on which speed setting you use, so the published runtime numbers can be misleading.

Who Should Buy the BLACK+DECKER LST522

The LST522 is ideal for homeowners who want the versatility of dual speed control without moving up to a more expensive 40V or 60V platform. If you alternate between light trimming and moderate weed clearing on a small to medium property, the two speed settings let you match power to the task.

It is also a good fit for anyone who values the wheeled edger feature for creating professional-looking edges along driveways and walkways without buying a separate tool.

Who Should Look Elsewhere

Users who need more than 35 minutes of runtime should look at higher-voltage options. The 20V MAX platform has inherent limits on sustained power delivery. Anyone with heavy vegetation or large properties would be better served by the EGO 56V, RYOBI 40V, or DEWALT 60V systems.

8. BLACK+DECKER LCC340C 40V – Best Trimmer and Sweeper Combo Kit

The BLACK+DECKER LCC340C is unique in our lineup because it gives you two tools for the price of one. The kit includes both a 13-inch string trimmer and a cordless sweeper (leaf blower), sharing the same 40V battery and charger. For homeowners who need both trimming and blowing capability, this combo represents excellent value. I used the trimmer for fence-line cleanup and the sweeper for clearing the driveway and walkway afterward.

The 40V POWERDRIVE high-torque transmission provides noticeably more cutting power than the 20V BLACK+DECKER models. The 13-inch cutting swath handles moderate grass and weeds effectively. The Automatic Feed Spool advances line without bumping, and the overall feel is more substantial than the brand’s 20V offerings.

The sweeper produces 130 MPH airflow, which is sufficient for clearing grass clippings, leaves, and light debris from hard surfaces. It is not a replacement for a dedicated gas blower, but for cleanup after trimming, it does the job. The state-of-charge indicator on the battery is a helpful feature that lets you check remaining power at a glance.

My main complaint is the edger guide design. Previous BLACK+DECKER models had a proper guide wheel, but this version uses a flimsy metal guide that does not track as cleanly along edges. The sweeper also struggles with wet leaves and heavy debris. Some users have reported that the battery voltage drops sharply near the end of the charge cycle, giving you less warning before the tool shuts off.

Who Should Buy the BLACK+DECKER LCC340C

This combo kit is perfect for homeowners who need both a string trimmer and a basic leaf blower but do not want to buy two separate tools with different battery systems. If your yard work consists of trimming edges and then blowing off the driveway and walkways, this kit handles both tasks efficiently.

It is also a strong choice for anyone already using BLACK+DECKER 40V outdoor tools, since the battery is cross-compatible with the rest of the lineup.

Who Should Look Elsewhere

If you need a dedicated, high-performance string trimmer without the sweeper, you can get better cutting performance for the same money from the RYOBI 40V or Greenworks 40V. Anyone with a large property who needs extended runtime should also look at higher-capacity battery options.

9. Greenworks 40V 12 Inch – Best Mid-Range Battery String Trimmer

The Greenworks 40V 12-inch string trimmer occupies the sweet spot between budget and premium. With nearly 4,000 reviews and a 4.4-star rating, it has built a strong following among homeowners who want more power than 20V models offer without paying for 60V systems. The 7500 RPM motor with a 12-inch dual-line cutting path handles tall grass and moderately thick weeds with confidence.

I was impressed by the cutting power relative to the price. This trimmer handled a patch of tall fescue that had grown to about 10 inches without stalling. The auto feed line system advances 0.065-inch dual line without bumping, and in my testing it worked reliably. The variable speed trigger is a nice touch at this price point, letting you conserve battery on lighter tasks.

The Greenworks 40V platform is one of the biggest in the outdoor power equipment space, with over 75 compatible tools. If you buy this trimmer, you are investing in a battery ecosystem that powers everything from mowers to chainsaws. The 3-year warranty on both the tool and battery is also above average for this category.

Battery runtime is the main weakness. I got about 25 to 30 minutes of moderate trimming on a full charge. That covers small to medium yards, but anyone with a half-acre or more will need a second battery. Some users have also reported issues with the charge indicator lights on the battery not displaying correctly, though the battery itself charges and performs normally.

Who Should Buy the Greenworks 40V

This trimmer is an excellent choice for homeowners with quarter-acre to half-acre properties who want a step up in power from 20V models without the cost of 60V systems. If you are already in the Greenworks 40V ecosystem, adding this trimmer is a natural expansion.

Anyone who values a strong warranty will appreciate the 3-year coverage on both tool and battery, which is longer than most competitors at this price point.

Who Should Look Elsewhere

Users with properties larger than half an acre should look at higher-voltage options for longer runtime. The 25-to-30-minute battery life is a real limitation for bigger jobs. Anyone needing to cut through heavy brush or woody weeds should step up to the Greenworks 60V model for significantly more cutting power.

10. Greenworks 60V 16 Inch – Most Powerful Battery String Trimmer

The Greenworks 60V 16-inch string trimmer is the most powerful model in our roundup, and by a significant margin. The brushless motor spins at a blistering 10,000 RPM through a 16-inch cutting swath. That combination of speed and width makes this the fastest cutter I tested. I cleared a dense strip of weeds along a fence line in a single pass that would have required two or three passes with most other trimmers.

The Load N’ Go line head is Greenworks’ answer to the EGO POWERLOAD. You thread the line through and it self-winds. It is not quite as seamless as the EGO system, but it is far easier than traditional manual winding. The attachment-capable design accepts Greenworks’ expanding line of 60V attachments, including edgers, pole saws, and blowers. The included shoulder strap is essential given the tool’s weight.

Battery life impressed me. The 4.0Ah 60V battery delivered over an hour of runtime on low speed and about 35 minutes on high. For reference, high speed on this trimmer cuts faster than any gas trimmer I have used in the past decade. The 4-year warranty on both tool and battery is the longest in our lineup and reflects Greenworks’ confidence in the build quality.

The elephant in the room is the weight. At 18.7 pounds with the battery installed, this is the heaviest trimmer we tested by far. Even with the shoulder strap, my shoulders and arms were fatigued after 30 minutes. This is not a tool for quick touch-up jobs. Some users have also reported concerns about long-term head durability, though the 4-year warranty provides some peace of mind.

Who Should Buy the Greenworks 60V

This trimmer is built for people who need maximum cutting power in a cordless package. If you have a large property with heavy vegetation, overgrown fence lines, or dense brush patches, the Greenworks 60V handles it all. Professional landscapers who want to transition away from gas without sacrificing performance should also consider this model.

Anyone already invested in the Greenworks 60V ecosystem gets the benefit of sharing batteries across 75+ tools. The 4-year warranty also makes this a confident long-term investment.

Who Should Look Elsewhere

If you cannot comfortably handle an 18.7-pound tool for extended periods, look at lighter options. The EGO Power+ and RYOBI 40V offer strong performance at significantly lower weights. Homeowners with small, well-maintained lawns do not need this level of power and would be paying for capability they never use.

11. Husqvarna 320iL 40V – Best Professional-Grade Battery Trimmer

The Husqvarna 320iL brings professional-grade engineering to the cordless string trimmer category. Husqvarna has been building professional landscaping equipment for decades, and that experience shows in the design details. The tool body itself weighs just 7 pounds, making it one of the lightest in its power class. The dual-direction trimmer head lets you switch cutting direction to manage where clippings fall, which is a feature typically found only on commercial-grade gas trimmers.

The Power Boost mode delivers 20 percent more power for heavy grass and dense vegetation. I used it to clear a section of thick, wet grass near a downspout, and the boost mode pushed through without bogging down. The active cooling system keeps the motor running at optimal temperature, and the LED on/off indicator is a simple but thoughtful touch that prevents accidentally leaving the tool on.

The Rapid Replace trimmer head allows you to swap heads without tools, which is a huge time-saver if you switch between different line types or need to replace a worn head in the field. The 4.0Ah battery is compatible with all Husqvarna 40V handheld equipment, giving you access to the brand’s full cordless lineup.

The main concern is runtime under sustained professional use. While the battery lasts long enough for average homeowner needs, landscapers working all day will need multiple batteries. Some users have reported overheating during extended sessions, which contradicts the active cooling system’s purpose. The included trimmer line is also thinner than I would expect at this price point and may need upgrading for heavy use.

Who Should Buy the Husqvarna 320iL

This trimmer is ideal for homeowners who want professional-grade build quality and design features at a reasonable cost. The dual-direction head and Power Boost mode set it apart from most homeowner-grade options. If you already own Husqvarna 40V tools, adding the 320iL completes your cordless outdoor collection.

Semi-professional users who need a reliable, well-built trimmer for regular use will also find value here. The lightweight design and thoughtful engineering make long sessions more comfortable.

Who Should Look Elsewhere

Full-time professional landscapers who need all-day runtime should look at the Greenworks 60V or DEWALT FlexVolt systems, which offer more power and longer sustained operation. Budget-conscious buyers can find similar cutting performance from the RYOBI 40V at a lower price point.

12. VARSK 20V 12 Inch – Best Budget Cordless Weed Wacker Kit

The VARSK 20V is the most affordable trimmer in our lineup, and it packs an impressive amount of value into a budget package. For the price, you get the trimmer, two 2.0Ah batteries, a charger, and six replacement spools. That is a complete trimming setup that most competitors would charge significantly more for. I tested it on a small townhouse yard, and it handled regular grass trimming and light edging without any issues.

The 8700 RPM motor is actually faster than several more expensive models in our lineup. The 2-in-1 design converts between trimmer and edger with a 90-degree head rotation. The automatic line feed eliminates the need to bump the head on the ground, and the 180-degree adjustable handle combined with the 80-degree pivoting cutting head lets you attack grass from multiple angles comfortably.

Each battery provides about 25 to 30 minutes of runtime, and having two batteries means you can trim for nearly an hour total. The 6.73-pound weight makes this one of the lightest options available, easy for anyone to handle. Assembly is straightforward, and the included spools mean you will not need to buy replacement line for months.

The trade-offs are clear when you push the VARSK beyond its intended use. Thick weeds and tall, overgrown grass cause the motor to struggle. The small spools run through line quickly in heavy conditions. This is a light-duty tool through and through, designed for regular maintenance on small properties, not for reclaiming overgrown lots.

Who Should Buy the VARSK 20V

This trimmer is the perfect entry-level option for first-time homeowners, renters, or anyone with a small yard who needs basic trimming and edging capability. The complete kit with two batteries and six spools means you have everything you need from day one with no additional purchases required.

It is also a smart backup trimmer to keep in a garage or shed for quick touch-ups. The low price makes it easy to justify even if you already own a primary trimmer.

Who Should Look Elsewhere

Anyone with a yard larger than a quarter acre or properties with heavy vegetation needs more power and runtime. The VARSK handles maintained lawns well but cannot tackle overgrowth. Users looking for a long-term primary trimmer should consider investing in a higher-voltage platform like the EGO 56V or RYOBI 40V, which offer better durability and performance over years of use.

How to Choose the Best Battery String Trimmer for Your Yard

Picking the right battery string trimmer comes down to matching the tool’s capabilities to your specific yard and needs. After testing 12 models, here are the key factors that actually matter when making your decision. You might also find our guides on cordless electric lawn edgers and garden equipment guides helpful for building out your complete lawn care toolkit.

Voltage and Power

The voltage of your battery platform directly correlates with cutting power. Here is a practical breakdown of what each tier delivers:

20V systems like the WORX WG163 and BLACK+DECKER LST300 are best for small yards with light, maintained grass. They handle regular trimming and edging without trouble but struggle with anything beyond moderate vegetation. These are perfect for townhouse lots and small suburban properties.

40V platforms from RYOBI, Greenworks, BLACK+DECKER, and Husqvarna hit the sweet spot for most homeowners. They deliver noticeably more torque than 20V systems while keeping weight manageable. The RYOBI 40V with its 90-minute runtime and the Husqvarna 320iL with its dual-direction head both demonstrate what this voltage class can do.

56V and 60V systems from EGO, DEWALT, and Greenworks are where you find gas-equivalent performance. These models handle heavy weeds, thick brush, and large properties with authority. The Greenworks 60V spinning at 10,000 RPM and the DEWALT 60V with its attachment system represent the top tier of cordless cutting power.

Cutting Swath Width

Cutting swath determines how wide a path you cut with each pass. Wider swaths cover ground faster but reduce runtime since the motor works harder. Most models range from 12 to 17 inches. For small yards with tight spaces, 12 inches is ideal. For open areas and larger properties, 15 to 17 inches saves significant time. Several models, including the DEWALT DCST972X1 and RYOBI 40V, offer adjustable swath widths so you can switch between efficiency and precision on the fly.

Battery Runtime and Ecosystem

Real-world battery life varies significantly from manufacturer claims. Based on my testing, expect 70 to 80 percent of advertised runtime under normal use conditions. More importantly, consider the battery ecosystem. Buying into a platform like EGO 56V, DEWALT FlexVolt 60V, or Greenworks 40V/60V means your batteries power multiple tools. This is one of the biggest factors in long-term value.

The forum discussions I reviewed consistently highlight battery platform ecosystem as a top concern. Users on r/lawncare and LawnSite repeatedly emphasize choosing a brand based on which other tools you might eventually need, since batteries are the most expensive part of any cordless system.

Weight and Ergonomics

Weight matters more than most people realize until they are 30 minutes into a trimming session. The difference between the 5.5-pound WORX WG163 and the 18.7-pound Greenworks 60V is dramatic. For users with physical limitations or small yards that require precision rather than raw power, lighter tools are the better choice. Look for models with adjustable shafts, telescopic handles, and included shoulder straps to manage heavier weights.

Line Loading System

How a trimmer loads new line might seem minor, but it affects your experience every time you need to reload. The EGO POWERLOAD system is the gold standard, winding line automatically at the push of a button. Greenworks’ Load N’ Go system is nearly as convenient. Traditional bump-feed and manual-wind systems work but are more frustrating and time-consuming. If you hate dealing with tangled string, prioritize models with automatic loading systems.

Final Thoughts on the Best Battery String Trimmers

After three months of testing 12 cordless trimmers across different properties and conditions, the EGO Power+ ST1511T remains my top recommendation for most homeowners. Its POWERLOAD system, reliable 45-minute runtime, and gas-equivalent cutting power make it the most well-rounded battery string trimmer you can buy in 2026. For heavier work, the DEWALT DCST972X1 delivers the raw power and attachment versatility that larger properties demand.

For budget-conscious buyers, the WORX WG163 and VARSK 20V prove that you do not need to spend a lot to get capable cordless trimming. Both include multiple batteries and handle regular yard maintenance effectively. The RYOBI 40V remains the best value for users who want attachment capability and long runtime without premium pricing.

The battery platform you choose matters more than any single tool. Think about what other outdoor power equipment you might need, because your battery investment carries across the entire lineup. Whether you go with EGO, DEWALT, Greenworks, or RYOBI, all of these brands offer comprehensive ecosystems. You can also check our latest string trimmer deals to find current discounts on these models.
