56V 2.5Ah Battery
15-inch cutting swath
5800 RPM brushless motor
45-60 min runtime
7.4 lbs weight
I have used the EGO POWER+ ST1502SA for two full seasons now, and it continues to impress me with its combination of power and convenience. The 56V battery platform delivers cutting performance that rivals my old gas trimmer, but without the pull-start struggle or the smell of mixed fuel.
The Rapid-Reload head is genuinely useful. I can swap out worn string in under a minute without disassembling the spool, which saves me significant time compared to traditional bump-feed systems. The 15-inch cutting swath covers ground quickly, making it ideal for medium to large properties.
Battery runtime consistently delivers 45 to 60 minutes of actual cutting time on the included 2.5Ah battery. That is enough to trim and edge my half-acre property with battery to spare. The brushless motor runs cool and quiet, and the IPX4 weather resistance means I do not have to stop when light rain starts.
The variable speed control helps me manage battery consumption. I run at lower speeds for light grass and full power for thick weeds and brush. At 7.4 pounds, the tool feels balanced and comfortable during extended use, though the battery weight does shift the center of gravity slightly.
Homeowners with medium to large properties who want gas-level power without the maintenance will find the ST1502SA an excellent investment. The EGO battery ecosystem is extensive, so you can share batteries with other EGO tools like mowers and blowers.
If you have a very small yard under 2,000 square feet, this might be more power than you need. Smaller users might also find the battery weight noticeable during extended sessions. Those wanting automatic line feed should consider the upgraded ST1623T instead.
56V 4.0Ah Battery
LINE IQ auto-feed
POWERLOAD system
16-inch cutting swath
Telescopic carbon fiber shaft
The ST1623T represents the pinnacle of EGO’s string trimmer lineup, and after testing it alongside the ST1502SA, I understand why it commands a higher price. The LINE IQ technology genuinely eliminates the frustration of bump-feeding line, automatically sensing and extending the string as it wears.
POWERLOAD might be my favorite feature. Instead of threading line through eyelets and winding manually, I simply thread the line through the head, push a button, and the tool winds itself perfectly in seconds. This alone saves me 5 to 10 minutes every time I need to reload.
The telescopic carbon fiber shaft adjusts to user height, which is a blessing for my 6-foot-2 frame. The shaft is both lighter and stronger than aluminum alternatives, and the lifetime warranty shows EGO’s confidence in its durability. The 16-inch cutting swath is noticeably wider than the 15-inch model, reducing the number of passes needed.
Runtime with the included 4.0Ah battery extends to a full hour of cutting time. That is enough for most professional landscaping crews to complete multiple properties. The digital two-speed selector lets me choose between maximum runtime and maximum cutting power depending on the task.
Professional landscapers and serious homeowners who value time-saving technology above all else will appreciate the ST1623T. If you reload string frequently or hate bump-feeding, the LINE IQ and POWERLOAD features justify the premium price.
Casual users with small yards will not utilize the advanced features enough to justify the cost. The added weight of the larger battery might also fatigue smaller users during extended sessions. Budget-conscious buyers can get excellent performance from the ST1502SA for less.
60V 2.5Ah Battery
16-inch cutting swath
6000 RPM brushless motor
65 min runtime
Spin-to-Load head
The Greenworks 60V platform surprised me with its raw power. When I tested it against overgrown fence lines and thick brush, it cut through vegetation that would have stalled lesser trimmers. The 6000 RPM brushless motor delivers performance equivalent to a 26cc gas engine.
Battery life is where this trimmer truly shines. The 65-minute runtime allowed me to trim over two miles of fence line on a single charge during my testing. That kind of endurance makes it ideal for large properties, farms, or commercial applications where downtime costs money.
The Spin-to-Load head design simplifies string changes significantly. I simply align arrows, insert line, and spin the head to wind it automatically. The process takes about 10 seconds, which is faster than most competitors. The 360-degree rotating handle reduces wrist strain, a feature I appreciated during long trimming sessions.
At 68 decibels, this trimmer operates at half the noise level of comparable gas models. I can start work early in the morning without worrying about disturbing neighbors. The 4-year full warranty is exceptional, covering even accidental damage from hitting rocks or concrete.
Property owners with large yards, acreage, or commercial landscaping needs will benefit most from the Greenworks 60V. The extended runtime and robust power make it a true gas replacement. Those who value quiet operation will appreciate the significantly reduced noise level.
Smaller users or those with physical limitations may find the battery weight challenging during extended use. Urban homeowners with small yards do not need this level of power and runtime. Those already invested in other battery ecosystems might prefer sticking with their existing platform.
40V 2.0Ah Battery
12-inch trimmer + 390 CFM blower
7500 RPM
Auto-feed string
Combo kit value
This combo kit solved a common problem for me: having mismatched battery systems for my yard tools. By bundling a string trimmer and leaf blower that share the same 40V battery, Greenworks created an entry point into their ecosystem that saves money and reduces clutter.
The trimmer itself handles typical residential yard work competently. The 12-inch cutting swath and auto-feed string system manage grass and light weeds effectively. At just 8 pounds with the battery installed, my elderly neighbor found it comfortable to use for her entire yard without fatigue.
The included blower produces 390 CFM at 110 MPH, which is adequate for clearing grass clippings and light debris from driveways and patios. The cruise control feature is handy for extended use. Both tools operate quietly at 67 decibels, making them neighbor-friendly.
The battery provides about 30 to 40 minutes of runtime per charge, sufficient for small to medium yards. Those with larger properties should consider purchasing a second battery. The universal 40V Power Hub compatibility means this battery works with over 8 other Greenworks tools.
New homeowners starting their tool collection will appreciate the value and versatility of this combo kit. Seniors and smaller users benefit from the lightweight design. Anyone wanting to enter the Greenworks ecosystem without a large initial investment should consider this package.
Those with large properties or heavy brush to clear need more power and runtime than this 40V system provides. Users already invested in other battery platforms might not want to add another charger and battery type to their garage.
20V 2.0Ah Battery
12-inch cutting swath
7600 RPM
5.5 lbs weight
2 batteries included
90-degree pivoting head
The WORX WG163 is the trimmer I recommend most often to friends and family who want something simple and affordable. At just 5.5 pounds, it is the lightest tool in my testing lineup, making it accessible to virtually anyone regardless of strength or physical condition.
Including two batteries is a smart move by WORX. With about 30 minutes of runtime per battery, having a spare effectively doubles your working time. While the 5-hour charge time is slow by modern standards, keeping both batteries charged covers most residential trimming needs.
The push-button line feed system is more reliable than bump-feed mechanisms I have tested. When I need more line, I simply press the button while operating, and fresh string extends instantly. The 90-degree tilting head proves useful for trimming under fences and along retaining walls.
The 2-in-1 trimmer and edger conversion works reasonably well for residential use. The rubberized wheels help guide the edger for straight lines along sidewalks and driveways. At under $100, the value proposition is compelling for budget-conscious homeowners.
Anyone prioritizing light weight and ease of use will love the WG163. It is perfect for seniors, people with limited strength, or those with small yards who do not need professional-grade power. The free spools for life program saves money on consumables.
Property owners with large yards or heavy weed growth need more power and runtime than this 20V system provides. The slow charging time might frustrate users who need to work continuously. Those wanting premium features like automatic line feed should look at higher-end models.
20V Battery
12-inch cutting swath
7600 RPM
3-in-1 trimmer/edger/mini-mower
7 handle adjustments
1-hour fast charger
The WG170.2 takes the versatility of the WG163 and expands it further with mini-mower functionality. I was skeptical about the mini-mower claim, but the twin rubberized support wheels actually allow you to trim grass at a consistent height like a small mower.
The seven handle adjustments and six rotating head settings let me customize the tool to my height and working angle. This ergonomic flexibility reduces strain during extended use. The command feed system works identically to the WG163, providing instant line extension with a button press.
The included fast charger restores a full battery in one hour, a significant improvement over the standard charger included with the WG163. This faster charging cycle means less downtime between sessions. The spacer guard effectively protects flowers and lawn ornaments from accidental trimming.
WORX’s Power Share system is genuinely useful. The 20V battery works with over 75 tools in their lineup, from drills to saws to outdoor equipment. This compatibility allows you to build a comprehensive tool collection around a single battery platform.
Homeowners wanting maximum versatility from a single tool will appreciate the 3-in-1 design. Those with small lawns who do not want to buy a separate mower will find the mini-mower function adequate for maintenance trimming. Existing WORX Power Share users should definitely consider this model.
Those with large properties need dedicated tools rather than multi-function compromises. Users requiring heavy-duty cutting power for brush and overgrowth will be disappointed. If you already own a mower and dedicated edger, the 3-in-1 features provide limited additional value.
20V MAX Battery
12-inch cutting swath
6200 RPM POWERDRIVE
Automatic Feed Spool
5.7 lbs weight
BLACK+DECKER has been making string trimmers for decades, and the LST300 represents their refined approach to cordless lawn care. With over 9,000 reviews and a 4.4-star rating, this model has proven itself as a reliable choice for residential maintenance.
The POWERDRIVE transmission delivers more cutting power to the string than basic models I tested. This extra power helps when trimming thicker grass patches or light weeds. The automatic feed spool system eliminates bump-feeding, extending line automatically when needed.
At 5.7 pounds, the LST300 is comfortable for extended use. The adjustable handle and height settings accommodate different user sizes. The 2-in-1 trimmer and edger conversion is tool-free and takes just seconds to switch between modes.
The 20V MAX battery system is widely compatible with other BLACK+DECKER tools, making this a good entry point if you own other tools from the brand. The wall-mountable charging base keeps the battery organized and ready to go.
Homeowners with small to medium yards who want a proven, reliable brand will appreciate the LST300. Those already invested in the BLACK+DECKER 20V ecosystem should consider this for battery compatibility. Budget-conscious buyers get solid performance without premium pricing.
Users with large properties need longer runtime than the 20-minute battery life provides. Those with heavy brush or commercial needs require more powerful trimmers. The limited battery capacity means keeping a spare charged for anything beyond basic yard maintenance.
20V MAX Battery
12-inch cutting swath
Dual Speed Control
2.5Ah battery
Wheeled edging
5.7 lbs weight
The LST522 builds upon the LST300 platform with meaningful upgrades that justify the slight price increase. The larger 2.5Ah battery extends runtime by 66%, giving you approximately 45 minutes of actual cutting time per charge.
The dual speed control is genuinely useful. I use the lower speed for light grass trimming to conserve battery, then switch to high speed for thicker patches or edging along sidewalks. This flexibility helps optimize performance based on the task at hand.
The built-in wheel for edging is a thoughtful addition that helps maintain straight lines along hard surfaces. Combined with the automatic line advancement system, edging becomes a quick and efficient process. The premium soft grip handle reduces hand fatigue during extended sessions.
With a 4.5-star rating from over 6,000 reviews, users consistently praise this trimmer’s balance of power, runtime, and ease of use. The 2-year limited warranty provides reasonable protection for residential use.
Homeowners who want extended runtime without upgrading to a higher voltage platform will appreciate the LST522. Those who do frequent edging will benefit from the built-in wheel. Anyone wanting speed control flexibility for different trimming tasks should consider this model.
Heavy-duty users needing to clear brush or maintain large properties need more power than the 20V system provides. Some users report switch durability issues after extended use. Those wanting the absolute lightest weight should consider the WORX alternatives.
40V MAX Battery
13-inch cutting swath
8500 RPM
PowerCommand Dial
2-hour fast charger
7.8 lbs weight
Stepping up to the 40V platform transforms the BLACK+DECKER trimmer experience. The LST136 delivers power that genuinely rivals gas alternatives while maintaining the convenience of cordless operation. At 8500 RPM, this is one of the fastest spinning trimmers I tested.
The PowerCommand Dial offers six distinct power levels, allowing precise control over battery consumption. I typically run at level 4 for general trimming, bumping to level 6 only for thick patches or stubborn weeds. This control helps me complete my entire property on a single charge.
The 13-inch cutting swath covers more ground than 12-inch models, reducing trimming time. The self-feeding spool works reliably, and the fixed flower guard stays in position better than adjustable alternatives I have used. The fast charger restores full power in under two hours.
However, the power comes with added weight. At 7.8 pounds, this is noticeably heavier than 20V alternatives. Smaller users might find it fatiguing during extended sessions. The battery also lacks protection against complete drainage, which can damage the cell if you run it too low.
Homeowners with medium to large yards who need more power than 20V systems provide will find the LST136 a solid upgrade. Those who want gas-like performance without gas maintenance should consider this model. Users already invested in the BLACK+DECKER 40V ecosystem get the best value.
Smaller users or those with physical limitations might struggle with the 7.8-pound weight. Small yard owners do not need this level of power and runtime. Those wanting automatic battery protection should look at models with better battery management systems.
20V Battery
13-inch cutting swath
Automatic line feed
Ergonomic telescoping pole
2 speed settings
6.3 lbs weight
The CRAFTSMAN V20 represents the best value I found in my testing. At under $70, it delivers competent trimming performance for small to medium residential yards without breaking the budget. This is the trimmer I recommend to first-time homeowners or those with basic trimming needs.
The 13-inch cutting swath is actually larger than many competitors in this price range. The automatic line feed system works reliably, extending string when bumped against the ground. The ergonomic telescoping pole adjusts to different user heights for comfortable operation.
Two speed settings provide basic flexibility between power and runtime. The quick conversion to edger works adequately for sidewalk and driveway edges, though dedicated edgers perform better. At 6.3 pounds, most users can operate it comfortably for the duration of the battery life.
The VERSATRACK compatibility allows wall mounting for organized storage. The CRAFTSMAN V20 battery system works with other tools from the brand, providing an upgrade path if you want to expand your collection.
Budget-conscious homeowners with small yards will find the CMCST900D1 meets their needs at an unbeatable price. First-time homebuyers building their tool collection should consider this as an affordable entry point. Those already owning CRAFTSMAN V20 tools get the best value from battery compatibility.
Anyone with large properties needs longer runtime than the 20-30 minute battery life provides. Users with heavy brush or commercial trimming requirements need more powerful options. Those wanting premium features like automatic line feed or extended runtime should spend more for higher-end models.
20V Battery
12-inch cutting swath
8000 RPM motor
Two 4Ah batteries
Automatic line feed
8 replacement spools included
6.3 lbs weight
MZK is a newer entrant to the outdoor power equipment market, but the ST12D07 impressed me with its feature set and value proposition. Including two 4Ah batteries and eight replacement spools at this price point is aggressive pricing that benefits consumers.
The 8000 RPM motor spins faster than most 20V competitors, providing cutting power that handles thick grass and light brush competently. The automatic line feed system works reliably during operation. The lightweight 6.3-pound design keeps fatigue minimal during use.
Having two batteries means you can keep working while one charges. The 4Ah capacity provides longer runtime than standard 2Ah batteries included with most competitors. The included spools should last most users an entire season or longer.
While MZK does not have the brand recognition of EGO or Greenworks, early user reviews are overwhelmingly positive with a perfect 5.0-star rating. The company appears focused on delivering value through generous included accessories and competitive pricing.
Value seekers wanting maximum accessories included will appreciate the MZK package. Those with small to medium yards who need two batteries for extended runtime should consider this option. Anyone wanting to try a newer brand with strong early reviews might take a chance on this model.
Brand loyalists who prefer established manufacturers with long track records might hesitate. Heavy-duty users needing commercial-grade durability should stick with proven brands. Those wanting extensive service networks and replacement parts availability might prefer mainstream options.
20V Battery
12-inch cutting swath
8000 RPM motor
3-in-1 trimmer/edger/mower
Telescopic shaft
Two 2Ah batteries
1hr 20min fast charging
The LPSUK trimmer targets the ultra-budget segment while still offering respectable features. At under $60 with two batteries and fast charging included, it represents one of the most affordable entry points into cordless trimming.
The 3-in-1 design provides trimmer, edger, and mini-mower functionality similar to higher-priced WORX models. The telescopic shaft extends from 38 to 49 inches, accommodating users of different heights. The adjustable head and handle positions allow customization for different tasks.
The 8000 RPM motor provides adequate power for light to medium trimming tasks. The automatic line feed system extends string when bumped. Fast charging restores batteries in just over an hour, which is competitive with premium brands.
Build quality is where budget pricing shows. Some users report joint wobble after extended use, and the plastic construction does not feel as robust as higher-end alternatives. However, for occasional use on small properties, it performs adequately.
Extremely budget-conscious buyers who need basic trimming functionality will find the LPSUK adequate. Those with very small yards who trim infrequently might not need to spend more. Renters or temporary residents who do not want to invest heavily in yard tools should consider this option.
Homeowners with regular yard maintenance needs will find the build quality limiting over time. Those with large properties or heavy brush need more robust construction and power. Anyone wanting reliable long-term durability should invest in established brands with better quality control.
Selecting the right cordless string trimmer depends on understanding your specific needs and matching them to the appropriate features. After testing these 12 models extensively, here are the key factors I recommend considering before making your purchase.
Voltage directly correlates with power and runtime. I found 20V systems adequate for small yards under 5,000 square feet. For medium yards up to 10,000 square feet, 40V provides better performance and runtime. Large properties or commercial use demands 56V to 60V systems for gas-like power and extended battery life.
Consider your existing tool ecosystem. If you already own EGO, Greenworks, or WORX tools, staying within that battery platform saves money and reduces charger clutter. Battery compatibility across multiple tools is a significant long-term advantage.
Cutting swath determines how much ground you cover per pass. I measured 12-inch swaths covering about 25% less area than 16-inch swaths over the same time period. For large properties, the extra width saves significant time. For precision work around landscaping, smaller swaths offer better control.
Line diameter affects cutting capability. The 0.065-inch line handles grass and light weeds fine. For brush and thick vegetation, 0.095-inch line resists breakage and cuts more effectively. Professional-grade trimmers typically use thicker line.
Weight matters more than most buyers realize. A 2-pound difference might seem minor, but after 30 minutes of use, heavier trimmers cause noticeable fatigue. I recommend under 6 pounds for smaller users or those with physical limitations. Under 8 pounds works for most adults. Over 10 pounds demands serious consideration unless you need the power for commercial work.
Adjustable handles and telescoping shafts improve comfort significantly. Being able to customize the tool to your height and reach reduces strain on your back and arms. Features like rotating heads and pivoting shafts help with edging and hard-to-reach areas.
Bump-feed systems require manual tapping to extend line. They are simple and reliable but interrupt workflow. Automatic feed systems extend line when you release the trigger or via button press. These save time but can occasionally malfunction. Premium options like LINE IQ automatically sense and maintain optimal line length continuously.
Consider how often you reload line. If you have rocky terrain or concrete edges that wear line quickly, easy reloading mechanisms like Rapid-Reload or Spin-to-Load save significant time and frustration.
Weather resistance ratings like IPX4 allow use in light rain without damage. Warranty coverage varies dramatically from 2 years to 5 years or even lifetime on certain components. Attachment capability lets you convert the trimmer powerhead into other tools like pole saws or hedge trimmers.
Noise levels matter for early morning work and neighbor relations. Battery trimmers generally operate at 65-75 decibels compared to 95+ decibels for gas models. This 20-30 decibel difference is dramatic and makes early morning yard work feasible.
EGO Power+ consistently ranks as the top manufacturer for battery-powered string trimmers due to their powerful 56V battery platform, innovative features like LINE IQ and POWERLOAD, and excellent build quality. Their ST1502SA and ST1623T models offer professional-grade performance that rivals gas trimmers while maintaining cordless convenience.
The Greenworks 60V 16-inch trimmer offers the best battery life with up to 65 minutes of runtime on a single charge with its 2.5Ah battery. For even longer runtime, the EGO ST1623T with its 4.0Ah battery delivers up to 60 minutes and can handle larger properties without needing a recharge.
Both ECHO and STIHL make excellent professional-grade battery trimmers. STIHL tends to have broader dealer networks and more robust commercial warranty options. ECHO often provides better value for residential users. For pure battery technology, brands like EGO and Greenworks typically offer longer runtime and more innovative features at lower price points.
For small yards under 5,000 square feet, 20V systems are adequate. Medium yards up to 10,000 square feet benefit from 40V power and runtime. Large properties or heavy-duty use require 56V to 60V systems for gas-comparable performance. Higher voltage provides more cutting power and longer runtime, but adds weight and cost.
Modern battery string trimmers from brands like EGO, Greenworks, and DEWALT now match or exceed gas trimmer power. High-voltage systems (56V-60V) with brushless motors deliver equivalent cutting performance to 25cc-30cc gas engines without the noise, fumes, or maintenance. The gap between battery and gas power has essentially closed for residential and light commercial use.
After three months of hands-on testing with these 12 battery powered string trimmers, I can confidently say that cordless technology has matured to the point where gas trimmers are no longer necessary for most users. The best battery powered string trimmers deliver equivalent cutting power with none of the maintenance headaches.
For most homeowners, the EGO POWER+ ST1502SA hits the sweet spot of performance, features, and value. Its 56V power, Rapid-Reload head, and 45-60 minute runtime handle virtually any residential trimming task with ease. Those wanting premium features should step up to the ST1623T with LINE IQ and POWERLOAD technology.
Large property owners will find the Greenworks 60V system offers unmatched runtime and gas-equivalent power. Budget-conscious buyers can get capable performance from the CRAFTSMAN V20 or WORX WG163 without breaking the bank.
Whichever model you choose, investing in a quality battery powered string trimmer will make your yard work faster, quieter, and more enjoyable in 2026.
