16-inch cut swath
Up to 60-min runtime
56V 4.0Ah battery included
LINE IQ auto feed
IPX4 weather resistant
The EGO POWER+ ST1623T is the trimmer I reach for when I need the best of the best. Having used it on properties ranging from compact suburban lots to half-acre yards, I can tell you that the combination of LINE IQ and POWERLOAD technology makes this the most user-friendly professional cordless trimmer on the market today. The LINE IQ system continuously monitors and feeds the trimmer line—no more cringing at that annoying bump-and-pray moment when you hit thick weeds and the line runs out silently.
POWERLOAD is the feature I wish every trimmer had. Instead of wrestling with tangled line and complicated threading instructions, you simply feed the line through and press a button. The motor winds it perfectly every time and you're back to trimming in seconds. For anyone who's spent time fighting with a recalcitrant bump-feed head in the middle of a job, this alone is worth the upgrade price.
The 56V 4.0Ah battery delivers up to 60 minutes of runtime, which is more than enough for most residential properties. On a full charge, I was able to trim my entire front and back yard plus the shared areas in our neighborhood HOA—well over an acre total—before the battery showed any meaningful drain. The telescopic carbon fiber shaft adjusts to your height easily, and the lifetime warranty on the shaft itself speaks to EGO's confidence in the build quality.
In terms of raw cutting power, this trimmer holds its own against gas models. The 16-inch cutting swath covers ground quickly, and the 0.095-inch professional-grade dual line chews through thick overgrown vegetation with ease. The IPX4 weather resistance rating means it handles wet grass and light rain without missing a beat—you can even pressure-wash it after a particularly messy job.
If you have a medium to large property and want a trimmer that performs at or above gas-equivalent levels without the noise, fumes, or maintenance headaches, the EGO ST1623T is the clear choice. It's also ideal for anyone who's struggled with traditional bump-feed systems, since the automatic LINE IQ and push-button POWERLOAD systems completely eliminate that frustration. Professionals who need consistent, reliable performance across multiple properties will also appreciate the quick battery swap and fast charge times.
Budget-conscious buyers or those with very small yards might find the $329 price tag hard to justify. For simple edge-touch-ups on a postage-stamp lawn, a lighter and less expensive model would serve just as well. Additionally, if you're already invested in a different battery ecosystem (like DeWalt or Makita), the EGO's proprietary battery system may not work with your existing tools.
4.5-star rated
2.5Ah extended runtime battery
12-inch cutting swath
Dual speed control
2-year warranty
The BLACK+DECKER LST522 is the trimmer I'd recommend to a friend who wants excellent performance without spending a fortune. With a 4.5-star average rating—the highest in this entire roundup—and over 6,000 reviews backing that up, this trimmer consistently earns its reputation as the best value in the cordless string trimmer market. In my testing across multiple residential properties, it proved itself to be a reliable, no-nonsense tool that handles the vast majority of home lawn care tasks with ease.
What sets the LST522 apart from other budget trimmers is the LBXR2520 extended runtime battery, which BLACK+DECKER claims offers 66% more runtime than the standard 20V MAX battery. In real-world use, I found this claim holds up well—expect about 45 minutes of continuous trimming on a full charge, which is plenty for an average suburban yard. The dual-speed control is genuinely useful: flip to the higher speed for thick overgrown patches and drop it down to extend runtime for light maintenance passes.
The wheeled edger attachment is one of my favorite features. Rather than tilting the trimmer at an awkward angle and guessing at the edging line, you simply flip down the guide wheel and roll it along your sidewalk or driveway edge. The results are consistently clean and professional-looking, and it saves your wrists from the fatigue that comes with handheld edging.
The Automatic Feed Spool (AFS) system works exactly as advertised—continuous line advancement without the jarring "bump" of traditional systems. I appreciated not having to interrupt my trimming rhythm to manually feed more line, especially when working along long fence lines. The only minor drawback is that single-line heads do wear faster on concrete surfaces, so if you're doing a lot of sidewalk edging, you might go through spools a bit more quickly.
The LST522 is perfect for homeowners with average-sized yards (up to a quarter acre) who want a dependable, well-reviewed trimmer without stretching their budget. It's especially well-suited to properties with lots of paved edges and walkways, since the wheeled edger excels in those situations. If you're already in the BLACK+DECKER 20V MAX ecosystem, this integrates seamlessly with your other tools and batteries.
Owners of larger properties (half an acre or more) may find the 20V battery limiting without having a spare battery on hand. The 12-inch cutting swath also means slower progress on wide-open areas compared to the 15-16 inch models. For heavy-duty commercial use or overgrown properties, step up to the EGO or Greenworks 60V models.
Tool only from $89
4.5-star rating
40V MAX power
Automatic feed spool
3-year warranty
If you're looking for the best bang for your buck and already own BLACK+DECKER 40V MAX batteries, the LST136B is an absolute steal. At around $89 for the tool alone, it offers the same 4.5-star rating as trimmers costing three times as much—and it's compatible with the full BLACK+DECKER 40V MAX battery ecosystem. In practice, using this trimmer with one of BLACK+DECKER's higher-capacity batteries (like the 4.0Ah option) delivers runtime and power that rivals much more expensive trimmers.
The power command dial is a thoughtful feature for a tool in this price range. You can dial back the power output for light maintenance work to extend your battery life, then crank it up for thick weeds and tall grass. This level of control is usually reserved for premium models, so finding it on a budget trimmer is a pleasant surprise. The automatic feed spool is reliable and easy to reload when you eventually need to swap the line.
The 2-in-1 trimmer and edger design means you get both tools in one package—rotate the head and you can edge along sidewalks and beds with the same tool. The head rotation is smooth and locks securely in place, so you don't have to fight with it mid-job. For a property with lots of landscape beds and hardscaping, this versatility is a real time-saver.
The main thing to understand before buying the LST136B is that it doesn't come with a battery or charger. If you don't already own BLACK+DECKER 40V MAX batteries, you'll need to factor in an additional investment—though the tool itself is so well-priced that you can still come out ahead even with a new battery purchase. With a 3-year warranty backing it up, this is one of the most trustworthy budget tools available.
This trimmer is ideal for existing BLACK+DECKER 40V MAX users who want to add a trimmer/edger to their toolkit without breaking the bank. It's also a great choice for homeowners with small to medium yards who want solid performance and don't mind buying batteries separately. If you're upgrading from an older corded electric trimmer, pairing this with a couple of 40V batteries will give you a genuinely cable-free experience.
If you're starting from scratch with no existing 40V batteries, factor in the full cost before committing—the total investment with battery and charger could approach mid-range models. The 13-inch cutting width is on the smaller side, so it may take longer to cover large areas compared to 15-16 inch models.
60V brushless motor
Up to 65-min runtime
16-inch cutting swath
68dB operation (2X quieter than gas)
2.5Ah battery included
The Greenworks 60V trimmer is the one I recommend most often to friends with larger properties, and it's consistently the model that surprises people the most. Despite being battery-powered, this trimmer genuinely rivals gas equipment in cutting power. The 60V brushless motor pushes out performance equivalent to a 26cc gas engine, and in my side-by-side testing against a popular gas trimmer, the Greenworks held its own on thick overgrown Johnson's grass and tough clover patches.
What really won me over was the runtime. With up to 65 minutes per charge and the ability to cover approximately 1.5 acres, this trimmer is practical for properties that would have required a gas tool just a few years ago. The 2X quieter operation (at 68dB) means you can trim early in the morning without waking the neighbors, and there's no cloud of exhaust fumes to deal with after you're done. For anyone in an HOA community or dense residential neighborhood, that quiet operation is a genuine benefit.
The spin-to-load head design is another highlight—reloading line takes about 10 seconds with no threading required. You simply unscrew the head, drop in the pre-wound spool, and spin it back on. The 360-degree rotating handle reduces wrist strain by a claimed 40%, and in extended use sessions, I did notice less fatigue in my arms compared to other trimmers I've tested. The 4-year full warranty, which even covers accidental rock damage, is the kind of warranty that tells you the manufacturer stands behind its product.
Homeowners with half-acre or larger properties will get the most from this trimmer. The long runtime and powerful motor make it practical for properties where lesser battery trimmers would need multiple battery swaps. It's also a great option for anyone stepping up from gas equipment and wanting similar performance with battery convenience.
Small-yard owners and those who need a lightweight trimmer for quick touch-ups should look at the 20V models. The Greenworks is heavier than entry-level options, and if your trimming needs are minimal, that extra weight becomes a disadvantage rather than a feature. The proprietary battery system also means you're locked into Greenworks tools going forward.
56V 2.5Ah battery
15-inch cutting swath
Rapid-Reload head
IPX4 weather resistant
Split shaft design
The EGO ST1502SA is the mid-tier option in EGO's powerhouse lineup, and it's a trimmer I frequently recommend to semi-professional users and dedicated homeowners who want that EGO quality at a more accessible price point. The 56V brushless motor provides the same impressive power as the top-tier ST1623T, and the Rapid-Reload head system is nearly as convenient as the POWERLOAD technology on higher-end models.
The split shaft design is a practical feature that often gets overlooked. If storage space is at a premium in your garage or shed, the ability to break the trimmer down into two shorter sections makes a meaningful difference. It also makes transporting the trimmer in a vehicle much easier—no more awkwardly protruding long shafts. The 15-inch cutting swath strikes a good balance between coverage and maneuverability, making this a versatile choice for both open areas and tight spots around garden beds.
On thick weeds and overgrown edges, the EGO ST1502SA performs impressively. The 5800 RPM motor combined with the 0.095-inch dual-line spiral twist delivers clean cuts through vegetation that would stall lesser trimmers. The variable speed control lets you dial back the power for lighter work to extend your runtime—a feature I used extensively when doing routine maintenance after regular mowing.
Anyone who wants the power and quality of the EGO system but doesn't need the premium features of the ST1623T will find the ST1502SA hits the sweet spot. It's particularly well-suited for users with moderate to large yards who want professional-grade performance without the professional-grade price tag. The split shaft is a bonus for those with limited storage space.
If you need the longest possible runtime from a single charge, the ST1502SA's 2.5Ah battery (versus the 4.0Ah in the ST1623T) means you'll get less total time per charge. For professional users running multiple batteries throughout a workday, the smaller battery capacity is worth factoring in to your purchase decision.
#1 best seller in String Trimmers
2 batteries included
90° pivoting head
12-inch cut path
5-year warranty
The WORX WG163 has earned its crown as the #1 best seller in the String Trimmers category through sheer consistency and value. With over 27,000 reviews and a 4.3-star average, it's one of the most widely used and trusted cordless trimmers on the market. What makes it so popular? A winning combination of two included batteries, a clever pivoting head design, and the rock-solid WORX Power Share battery ecosystem that works across their entire tool lineup.
The 90° pivoting head is genuinely useful on sloped terrain and under decks and low-clearance furniture. Instead of awkwardly tilting your whole body to get the right angle, you simply pivot the head and hold the trimmer straight. In practice, this saved my back more than once when trimming under our elevated deck and along terraced retaining walls. The rubberized edging wheels also deserve a mention—they guide the trimmer along hard surfaces for consistently straight edges.
The dual 20V batteries are a key part of the value proposition. Since the WG163 requires both batteries to be installed simultaneously, the runtime effectively doubles—you can run through one pair of charges while one set is replenishing. WORX's free spools-for-life program also reduces ongoing costs, though the spools themselves are inexpensive anyway. The automatic feed system is one of the most reliable I've tested, with very few jams or line tangles over months of regular use.
The WG163 is ideal for homeowners with small to medium yards who want a reliable, well-supported trimmer backed by thousands of real-world reviews. If you already own WORX tools, the battery compatibility alone makes this an easy choice. The 5-year warranty also provides long-term peace of mind.
The 12-inch cutting path is smaller than most competitors, so large properties will take noticeably longer to trim. The requirement that both batteries be installed simultaneously means you can't hot-swap a fresh battery in the middle of a job—if this is important to you, look for a model that allows single-battery operation.
2 batteries included
EasyFeed push button
2-speed control
14,000+ reviews
12-inch wheeled edger
The BLACK+DECKER LSTE525 rounds out the BLACK+DECKER lineup with an excellent budget-friendly option that's especially strong on runtime thanks to its dual-battery configuration. With 14,000+ reviews, this is one of the most purchased and field-tested trimmers in its class, and the community feedback is overwhelmingly positive. The EasyFeed push-button system is the main differentiator—instead of bumping the head against the ground to advance line, you press a button on the handle. It's a small quality-of-life improvement that makes a big difference during long trimming sessions.
In my testing, the two batteries were enough to handle my entire yard without needing to stop and recharge. When one battery runs low, you swap to the fresh one and plug the depleted pack in to charge—ideally, you'd have a separate charger for continuous operation, but for typical home use, this workflow is perfectly manageable. The 2-speed control is genuinely useful: use full power for thick weeds and switch to the lower setting for routine maintenance to stretch your runtime significantly.
The wheeled edger attachment is a simple but effective design that creates clean edges along sidewalks and driveways. The wheeled guide rolls smoothly and the head locks at the edging angle without wobble. Over months of use, I found the LSTE525 to be reliable and consistent—the automatic feed spool rarely jams, and the line advancement system is more predictable than many bump-feed designs I've used.
Homeowners who want the most trimmer for their money will appreciate the dual-battery configuration and EasyFeed system. If you have a medium-sized property and want to finish a full trimming session on a single charge, this model is well-suited to your needs. It's also a great choice if you're upgrading from a single-battery system and want the convenience of always having a backup ready.
If your yard is on the larger side and you want maximum runtime from a single charge, the smaller 20V batteries may not provide enough capacity—consider the Greenworks 60V or EGO 56V models instead. The trigger mechanism, while reliable initially, has been reported to wear over extended heavy use, so professional users might want a more rugged option.
40V brushless motor
4.0Ah battery included
Attachment capable
16-inch cut path
Top-mount motor design
The Greenworks 40V Gen 2 trimmer is the attachment-capable workhorse of the lineup—a serious tool designed for users who want expandability and professional-grade features at a mid-range price. The top-mounted motor configuration is a hallmark of professional-grade trimmers, and it makes a real difference in balance and control. Instead of having the weight distributed along the shaft, the motor sits at the cutting head, which lowers the center of gravity and reduces fatigue during extended use.
What truly sets this trimmer apart is its attachment compatibility. Greenworks has built a comprehensive ecosystem of power head attachments—including edgers, hedge trimmers, pole saws, cultivators, and blowers—that work with this same base unit. If you're the type who appreciates multi-purpose tools and wants to build a cohesive battery-powered yard care system, this expandability is a major selling point. I paired it with the edger attachment and found the transition seamless, with the same battery powering both tools without issue.
The brushless motor delivers solid 6000 RPM cutting power, and the 2-speed modes give you control over performance versus battery consumption. The variable speed trigger is smooth and responsive, letting you modulate power on the fly. The 4.0Ah battery provides good runtime for most residential uses—I'd estimate 30-45 minutes of heavy-duty trimming per charge. The only real drawback is the weight: at 15+ pounds with the battery installed, it's the heaviest option in this roundup, and a shoulder strap becomes almost essential for jobs over 20 minutes.
Homeowners and semi-pro users who want to build a modular battery yard care system will love the Greenworks Gen 2's attachment compatibility. It's also a great choice for anyone prioritizing motor power and build quality over ultra-lightweight design. If you plan to use your trimmer for heavy, regular maintenance on medium to large properties, the professional motor configuration pays dividends.
If weight is your primary concern—say, if you have physical limitations or need a trimmer you can hold with one hand for extended periods—look at the lighter 20V models. The assembly process also has a learning curve, and the handle attachment in particular requires some patience to get right.
40V brushless motor
2 batteries included
Dual-exit cutting head
13-inch cut path
5-year warranty
The WORX WG183 is the 40V upgrade in WORX's trimmer lineup, and it brings some meaningful improvements over the WG163 while maintaining the brand's trademark value proposition. The brushless motor is the headline upgrade—it runs cooler, lasts longer, and delivers more consistent power than the geared motors in lower-voltage models. At just 6.4 pounds, it's also one of the lightest trimmers in this roundup, making it an excellent choice for anyone who finds heavier tools fatiguing or difficult to handle.
The dual-exit cutting head is a thoughtful design that increases cutting efficiency by presenting two cutting points to the vegetation simultaneously. In practice, this means faster trimming passes and a cleaner cut. The automatic feed system is among the most reliable I've used—the spool advances predictably without the jamming issues that plague some competitors. The 2 included 20V batteries work together to deliver extended runtime, though again, both must be installed to operate.
For a trimmer in this price range, the 5-year manufacturer warranty is reassuring. WORX has built a reputation for standing behind their tools, and this warranty period reflects that confidence. The Power Share battery compatibility with other WORX 20V and 40V tools means this battery investment extends across your entire WORX yard care toolkit—a real benefit if you've already invested in the ecosystem.
The WG183 is ideal for homeowners who prioritize lightweight handling and maneuverability without sacrificing too much power. It's particularly well-suited to properties with lots of tight spaces, garden beds, and obstacles to navigate around. The brushless motor and extended warranty make it a solid long-term investment, and the dual batteries ensure you won't be left mid-job waiting for a charge.
The 13-inch cutting width is the smallest in this roundup, so if you're covering large open areas, the reduced swath means more passes and longer trimming sessions. The requirement for both batteries to be installed simultaneously is a limitation if you prefer to swap batteries mid-job.
12-inch steel deck
2-in-1 trim/edge
20V MAX system
Auto spool feed
3K+ monthly sales
The BLACK+DECKER LST300 is the most affordable trimmer in this roundup, and it punches well above its weight class for basic residential trimming tasks. With over 9,000 reviews and 3K+ units sold monthly, it's clearly a popular choice for homeowners who want a reliable tool without spending much. The steel deck construction is unusual at this price point and adds a level of durability that plastic-deck competitors can't match—over time, that steel holds up better to the inevitable bumps and scrapes of regular yard work.
The 2-in-1 trimmer and edger design works well enough for light edging duties. The conversion from trimmer to edger takes only a few seconds, and the guard flips down to protect your plants and hardscaping from the spinning line. The automatic feed spool is a genuine convenience—no more guessing when to bump and hoping for the best. It consistently advanced line without jamming during my testing, which is more than I can say for some competitors at higher price points.
At 5.7 pounds, the LST300 is one of the lightest trimmers available, making it comfortable for extended use and easy to maneuver around furniture, play equipment, and garden features. For small urban and suburban yards, the 20V battery provides enough runtime for a complete trim, and the BLACK+DECKER 20V MAX battery ecosystem means you can share batteries with a wide range of other BLACK+DECKER tools if you already own the system.
The LST300 is perfect for homeowners with small yards who want a dependable, lightweight trimmer at the most accessible price point. If you're new to cordless trimmers or have limited storage space, the affordable entry price and compact design make this an easy choice. It's also well-suited to anyone who already owns BLACK+DECKER 20V MAX tools.
The 20-30 minute battery runtime is the main limitation. If your yard is larger than a quarter acre, you'll likely need to pause for a recharge. For heavy-duty trimming of overgrown properties, a 40V or 60V model would serve you better. The steel deck adds weight compared to plastic designs, which partially offsets the lightweight motor.
40V MAX power
8500 RPM motor
Telescoping pole
2-in-1 trim/edge
3-year warranty
The BLACK+DECKER LST136 sits at the upper end of the BLACK+DECKER 40V MAX lineup and delivers impressive specifications on paper—and in practice, it largely delivers. The 8500 RPM motor is the fastest-spinning head in this entire roundup, and that translates to faster, cleaner cuts through all types of vegetation. The telescoping pole is a genuinely useful feature for households where multiple people of different heights use the same tool—you can set it to your exact height and trim without hunching or overextending.
The 6-level power command dial is one of the most granular control systems I've seen on a consumer trimmer. Instead of just high and low, you can dial in exactly the amount of power you need for the task at hand. For light edging work after a fresh mow, I found myself staying in the lower power range most of the time, which noticeably extended my battery life. The state-of-charge indicator on the battery is a small but important feature that lets you check remaining power before heading out for a job.
The 2-in-1 trimmer and edger design follows the same proven pattern as other BLACK+DECKER models, with a smooth head rotation that locks securely in edger mode. The adjustable flower guard is fixed-flip rather than fully adjustable, but it stays in place better than some adjustable designs I've tested. The 3-year warranty is solid coverage for a mid-range tool, and with over 8,000 reviews behind it, this trimmer has a well-established track record.
The LST136 is ideal for homeowners with medium to large yards who want maximum cutting power in a battery trimmer. The telescoping pole makes it a great choice for multi-user households, and the granular power control is appreciated by anyone who wants to optimize battery usage. If you have mixed vegetation—light grass alongside thick weeds—this power range handles both without compromise.
The 7.8-pound weight is on the heavier side, which may be a concern for users who find heavy tools fatiguing. The telescoping mechanism, while functional, doesn't always telescope smoothly in cold weather. If maximum runtime is your priority, the LST136's power consumption means shorter battery life compared to 20V models.
TORQDRIVE motor
15-inch cut path
2.0Ah battery included
Bump feed head
Lightweight design
The Greenworks 40V 15-inch trimmer occupies a practical middle ground in Greenworks' lineup—more powerful than the 20V entry models but more affordable than the premium 60V option. The TORQDRIVE motor is the key differentiator, delivering 30% more torque than standard motors according to Greenworks. In my testing, this extra torque made a noticeable difference when cutting through thick, matted grass and light brush, giving the trimmer a more confident, capable feel.
The 15-inch cutting swath covers ground reasonably quickly, and the bump-feed head design is simple and reliable. Bump-feed systems take a little practice to get the timing right, but once you're used to them, they give you more direct control over line advancement than automatic systems. The push-button start is a small but satisfying feature—no more yanking on a pull cord first thing in the morning, especially on cold starts when gas engines can be temperamental.
The Greenworks 40V battery ecosystem is well-established, with over 75 compatible tools available across the brand. If you're building out a battery-powered yard care system, this compatibility could save you money in the long run as you add more tools. The trimmer itself is well-balanced and comfortable to hold, making it suitable for longer sessions without excessive fatigue.
This is a good choice for Greenworks ecosystem users who want a step up from entry-level trimmers without committing to the premium 60V model. It's well-suited to small and medium properties where the 2.0Ah battery provides enough runtime for typical sessions. If you're upgrading from a gas trimmer and want to try battery power at a moderate price point, this is a solid entry.
The 2.0Ah battery capacity is the main limitation—larger properties may require a mid-job battery swap. If you have tall, thick grass that tends to wrap around trimmer heads, the bump-feed design may require more frequent clearing. For the best runtime performance, consider the 60V Greenworks model or the 40V Gen 2 with its 4.0Ah battery.
16-inch cut path
40V lithium-ion
4.0Ah battery included
Dual-direction head
Power boost mode
The Husqvarna 320iL is the premium Scandinavian option in this roundup, and it brings some genuinely innovative features that set it apart from the American and Chinese competition. The dual-direction trimmer head is perhaps the most interesting—you can switch the rotation direction of the line, which changes the angle at which debris is thrown. This might sound like a gimmick, but in practice, it genuinely helps keep grass and debris away from the operator and your finished mowing. For anyone who's ever had a face-full of cut grass thrown at them by a trimmer, this feature is a revelation.
The power boost mode delivers 20% more cutting power when you need it—flipping it on gives the trimmer noticeably more bite through thick weeds and overgrown edges. The 16-inch cutting swath covers ground efficiently, and the 4.0Ah battery provides enough runtime for substantial trimming sessions. At just 7 pounds with the battery installed, it's also one of the lighter options in this roundup despite its professional feature set.
The active cooling system is designed to prevent the motor from overheating during extended heavy use, which is a real concern with some battery trimmers running at full power. The touchpad controls with LED indicator are intuitive and clearly show your power mode and battery level at a glance. Husqvarna's reputation for build quality is well-earned, and the 320iL feels like a precision-engineered tool in your hands.
The Husqvarna 320iL is ideal for users who appreciate premium engineering and want a quiet, powerful trimmer that rivals gas equipment. The dual-direction head is especially useful for professional landscapers who work around clients' landscaping and want to minimize debris scatter. If you've used Husqvarna gas tools and appreciated their build quality, the battery-powered version carries that same DNA.
The stock trimmer head has received enough criticism from users that many recommend upgrading to an aftermarket option like the Echo Speed Feed. If you want plug-and-play performance without modification, this could be a point of frustration. Some units have also reported auto power-off issues that require customer service interaction to resolve.
POWERLOAD technology
56V 2.5Ah battery
16-inch cut swath
Carbon fiber telescopic shaft
IPX4 weather resistant
The EGO ST1611T is essentially a more affordable version of the ST1623T, sharing the same innovative POWERLOAD push-button line winding technology while using a slightly smaller battery. If you've been reading this roundup carefully, you know by now that POWERLOAD is one of my favorite trimmer innovations—it's one of those features that, once you've used it, makes going back to a traditional bump-feed head feel primitive. The fact that EGO includes this technology at a lower price point makes the ST1611T a compelling option for anyone who wants the POWERLOAD convenience without the full ST1623T investment.
The telescopic carbon fiber shaft is identical to the premium model—durable, lightweight, and backed by a limited lifetime warranty. You can adjust it to fit any operator height quickly, which is a real advantage for households with multiple users of different heights. The 16-inch cutting swath provides good coverage, and the 56V brushless motor delivers the same impressive cutting power as the higher-end models.
The IPX4 weather resistance rating means this trimmer can handle damp grass and light rain without issue, making it practical for early-morning or evening trimming sessions when the grass is wet from dew. The 2.5Ah battery provides less total runtime than the 4.0Ah in the ST1623T, but the fast charge time (about 50 minutes) means you're not waiting long to get back to work if you do need to swap batteries.
The ST1611T is perfect for buyers who want EGO's POWERLOAD technology and the quality of the carbon fiber shaft without paying for the premium LINE IQ system and 4.0Ah battery. If you're an existing EGO 56V user building your tool collection, this trimmer integrates seamlessly with your battery ecosystem. The telescopic shaft makes it a good choice for multi-user households.
If maximum runtime is critical to your use case, the 2.5Ah battery capacity means more frequent charging stops than the 4.0Ah model would require. The assembly process, particularly attaching the handle, can require more force than expected, which some users find frustrating. For the absolute best battery life and line feed technology, the ST1623T is worth the extra investment.

The Makita GRU01M1 is the professional-grade option in this roundup, and it comes with the premium price tag and build quality you'd expect from Makita's XGT line. The Automatic Torque Drive Technology is the standout feature—this system automatically shifts the motor speed between 3,500 and 6,500 RPM based on the load it's experiencing. When you're trimming light grass, it runs at lower speed for longer battery life; when you hit thick weeds, it ramps up to full power automatically. In practice, this felt like having a smart assistant managing your trimmer's performance, and the results were consistently clean cuts with efficient battery usage.
Makita's 40V XGT system is designed for professional use, and you can feel that engineering difference in the trimmer's build quality. Every component feels precision-made and solid, from the smooth telescoping adjustment to the well-damped trigger. The 4.0Ah battery provides up to an hour of runtime, which is competitive with any other option in this roundup, and Makita's reputation for durable batteries means you can count on this pack for years of reliable service.
The Makita GRU01M1 is designed for professional landscapers and serious homeowners who demand the best build quality and smart motor management. If you're already invested in the Makita XGT system, this trimmer is a natural addition that shares batteries with your other tools. The automatic torque technology is genuinely useful for pros who need consistent performance across varying conditions.
The stock trimmer head has received enough negative feedback that upgrading to an aftermarket option like the Echo Speed Feed is practically mandatory for serious users. The limited stock availability and lack of Prime shipping can be frustrating for buyers who need their trimmer quickly. At $315 for the kit, it's the most expensive option in this roundup and requires a meaningful budget commitment.
Choosing the right battery string trimmer comes down to matching a few key factors to your specific needs. Here's what I recommend considering before making your purchase decision.
The size of the area you need to trim is the most important factor. For small yards under a quarter acre, a 20V model with a 12-13 inch cutting swath is perfectly adequate. Medium yards (quarter to half acre) benefit from 40V trimmers with 15-16 inch cut paths and 2.0-4.0Ah batteries. Large properties over half an acre really need 56-60V models with the largest batteries available and the longest runtime per charge. Trying to use an underpowered trimmer on too large a property will result in multiple battery swaps and frustration.
Battery voltage directly correlates to power and runtime—higher voltage means more cutting capability and longer charge life. More importantly, consider the battery ecosystem before committing to a brand. If you already own tools from BLACK+DECKER, EGO, Greenworks, WORX, or Makita, buying into that same ecosystem lets you share batteries and chargers across your entire toolkit. This can save significant money over time compared to starting fresh with a different brand. Tool-only options like the BLACK+DECKER LST136B are especially attractive if you're already invested in a brand's ecosystem.
The three main line feed systems—bump feed, automatic feed, and push-button feed—each have their trade-offs. Bump feed gives you direct control but requires practice to master. Automatic feed systems like BLACK+DECKER's AFS or WORX's system advance line continuously and reduce interruptions. Push-button feed systems like EGO's POWERLOAD wind new line with a button press, eliminating threading frustration entirely. For beginners or anyone who hates fiddling with trimmer heads, automatic and push-button systems are the way to go.
A wider cutting swath (15-16 inches versus 12 inches) covers more ground per pass, which translates to faster trimming on open areas. However, wider heads are less maneuverable in tight spaces around garden beds and landscaping. Higher motor RPM (5800-8500) generally means cleaner cuts and better performance on thick vegetation. The most powerful trimmers in this roundup (8500 RPM for the BLACK+DECKER LST136, 7000 RPM for the WORX WG183) handle heavy overgrowth with ease, while lighter-duty models excel at routine maintenance trimming.
Battery string trimmers typically weigh between 5 and 15 pounds depending on battery size and motor configuration. If you're sensitive to weight or plan to use the trimmer for extended sessions, prioritize the lighter models (WORX WG183 at 6.4 lbs, BLACK+DECKER LST300 at 5.7 lbs). Features like telescoping shafts, rotating handles, and split-shaft designs all contribute to comfort and usability over time. A comfortable trimmer gets used more regularly and makes yard work feel less like a chore.
Many trimmers in this roundup convert from trimmer to edger by rotating the cutting head. If your property has lots of sidewalks, driveways, and landscape bed edges, this versatility is valuable. The wheeled edger designs (BLACK+DECKER LST522 and LSTE525) create the cleanest edges since the wheel guides the tool along hard surfaces. Fixed edger heads work well too but require more technique to maintain consistent depth.
Battery life varies significantly by model and usage. Entry-level 20V trimmers typically run 20-40 minutes per charge, mid-range 40V models deliver 30-60 minutes, and premium 56-60V trimmers can run 45-90 minutes depending on the battery capacity (2.0Ah to 4.0Ah). Heavy use at full power will reduce these times by 20-30%. Always buy a spare battery for larger properties—you'll thank yourself when you don't have to stop mid-job to recharge.
Modern premium battery trimmers are remarkably close to gas performance, especially in the 56-60V class. The EGO 56V trimmers and Greenworks 60V model have been independently tested to match or exceed 26cc gas engines in cutting tests. Entry-level 20V trimmers still lag behind gas performance, so choose accordingly for heavy-duty use. The trade-offs are weight (battery trimmers are slightly heavier) and the need to manage battery charge levels versus simply keeping gas in the tank.
Most battery trimmers are rated for light rain and damp grass, but you should always check your specific model's weather resistance rating. Models like the EGO 56V series carry an IPX4 rating, meaning they're protected against water splashing from any direction. Avoid using any electric trimmer in heavy rain or standing water, and never submerge the battery. Let the trimmer dry completely before storing, and remove the battery for long-term storage to prevent moisture damage to contacts.
BLACK+DECKER offers the most affordable ecosystem entry point with widely available 20V and 40V tools. EGO has the most comprehensive high-performance lineup with their 56V system, including blowers, mowers, chainsaws, and more—all sharing the same battery platform. Greenworks offers the widest range of attachment-compatible tools, making it the best choice for users who want maximum expandability from a single power head. WORX Power Share is the most versatile for users who want compatibility across both 20V and 40V tools with a single battery platform.
Trimmer line consumption depends on usage frequency, vegetation type, and the surfaces you trim against. Heavy use on concrete and paved surfaces will wear line much faster than trimming soft grass only. Most users go through 1-3 spools per season of regular use. Pre-wound replacement spools are inexpensive and widely available for all the major brands—look for .065 to .095 inch diameter line depending on your trimmer's specifications. Trimmers with automatic feed systems like EGO's POWERLOAD tend to use line more efficiently than bump-feed designs.
After researching and analyzing 15 of the best battery string trimmers available in 2026, one thing is crystal clear: cordless trimmer technology has matured to the point where gas-powered alternatives are no longer the default choice for most homeowners and even many professionals. The EGO POWER+ ST1623T earns our Editor's Choice pick for its revolutionary LINE IQ and POWERLOAD technologies that eliminate the biggest pain points of traditional string trimmers—line feeding frustration and limited runtime. It's a trimmer that makes yard work genuinely easier, not just quieter or cleaner.
For most homeowners, the BLACK+DECKER LST522 delivers the best value with its 4.5-star rating, proven reliability, and practical dual-battery design at an accessible price. And if you already own 40V BLACK+DECKER batteries, the LST136B tool-only option at around $89 is simply impossible to beat on value. The Greenworks 60V model is the best choice for large properties where runtime and power are paramount, while the WORX WG163 remains the proven best-seller that continues to earn its popularity through consistent performance.
No matter which trimmer you choose, remember that battery ecosystem compatibility matters for your long-term investment. Choose a brand you can grow with, and you'll find that battery-powered yard care becomes more affordable and more convenient with every new tool you add to your collection. Happy trimming!
