The best electric grass trimmers balance cutting reach, usable runtime, and comfortable handling for the size of your yard. My best overall pick is the Husqvarna 320iL, which pairs a 40V-class tool with a 4 Ah battery and charger for buyers who want a capable cordless setup. For value, the WORX WG163 offers a practical 2-in-1 trimmer-and-edger design, while the BLACK+DECKER BESTE620 suits shoppers who prefer a corded tool and do not want to manage battery charge. The main tradeoffs are cordless freedom versus runtime and corded consistency versus outlet reach, along with full-size cutting power versus compact tools for light trimming. Read on for the full breakdown, buying advice, and picks matched to different yards and budgets.

Key Takeaways
- The lineup splits into three useful groups: full-size cordless models for broader trimming, corded trimmers for steady power near an outlet, and compact shear-style tools for light detail work.
- Battery capacity and included batteries matter together: a larger battery can support longer sessions, while a second battery can reduce pauses if you can charge or swap it.
- Two-in-one edger designs add flexibility, but buyers should check how easily the tool switches modes and whether its cutting width fits their edging style.
- Brushless construction is a meaningful differentiator in the Greenworks 24V model; it can appeal to buyers prioritizing motor efficiency over simply choosing the highest voltage label.
- Product names can overstate the comparison: voltage alone does not establish cutting performance, so shaft design, cutting width, battery setup, and intended workload all belong in the decision.

More Details on Our Top Picks
Cordless Electric String Trimmer with Two Batteries
For compact yards, I’d favor this trimmer’s 5.3-pound weight and straightforward switch between trimming and edging over a wider, heavier machine. Its 12-inch cutting path suits routine grass and border cleanup, while automatic line feed removes the need to bump the head during work. Two included batteries give you a spare to swap in, but they don’t change the key limitation: listed average runtime is only about 12 minutes per battery. That makes this a better fit for short sessions than for clearing a large, overgrown lawn. Compared with the WORX WG183, it is lighter and explicitly converts to edging, but the WORX has a slightly wider head and batteries that work across its 20V and 40V tool range. I’d choose this for quick, modest jobs—not broad coverage.
Pros:- Light 5.3-pound build helps reduce fatigue during brief yard-care sessions
- Converts between string trimming and lawn edging
- Two 2.0 Ah batteries and a charger are included
- Automatic line feed and adjustable handle simplify routine use
Cons:- Listed average runtime is about 12 minutes per battery, limiting coverage
- Its 12-inch cutting width is less suited to large areas than the 16-inch Husqvarna 320iL
- Designed for small yards and everyday garden areas rather than demanding clearing
Best for: Owners of small, regularly maintained yards who want a lightweight trimmer that can also edge and prefer having a spare battery ready.
Not ideal for: People with large lawns or heavy weed growth who need longer uninterrupted runtime or a wider cutting path.
- Power source:Battery powered
- Battery voltage:21 V
- Batteries included:Two 2.0 Ah lithium batteries
- Listed average battery life:About 12 minutes per battery
- Cutting width:12 inches
- Motor speed:9,000 rpm
- Weight:5.3 pounds
- Functions:String trimming and lawn edging
- Line feed:Automatic
Our verdict“Choose this for a small yard and quick trim-and-edge jobs, but skip it if short battery sessions would interrupt your work.”
WORX WG183 40V 13-Inch Cordless String Trimmer
The WG183’s strongest reason to make my list is its WORX Power Share compatibility: owners of compatible 20V and 40V tools can use the included batteries across more than one device. For trimming, its 13-inch dual-exit head covers a little more ground per pass than the 12-inch heads on the HEYWORK and small-yard Cordless Electric String Trimmer. Automatic feed also keeps the job moving without manual bumping, and the package includes two batteries plus a dual charger. The tradeoff is that, at 6.4 pounds, it is heavier than the small-yard pick, while its listed 7,000 rpm motor speed is lower than that model’s 9,000 rpm figure. The supplied details don’t specify runtime, so I can’t rank it confidently for long sessions. It makes most sense for buyers who value battery-platform flexibility and a useful middle-ground cutting width.
Pros:- Batteries are compatible with WORX 20V and 40V Power Share tools
- 13-inch cutting width covers more ground than the 12-inch models in this batch
- Two 2.0 Ah batteries and a dual charger are included
- Automatic-feed spool and adjustable auxiliary handle support convenient operation
Cons:- At 6.4 pounds, it weighs more than the 5.3-pound small-yard trimmer
- No battery runtime is provided in the supplied specifications
- Battery usefulness beyond this trimmer depends on owning compatible WORX tools
Best for: WORX 20V or 40V Power Share owners who want a cordless trimmer with two included batteries and a cutting path suited to routine residential lawns.
Not ideal for: Shoppers outside the WORX battery platform who prioritize the lightest tool or need clearly stated runtime for larger jobs.
- Model:WG183
- Power source:Battery powered
- Cutting width:13 inches
- Speed:7,000 rpm
- Batteries included:Two 20V 2.0 Ah lithium-ion batteries
- Charger:2.0A dual charger
- Weight:6.4 pounds
- Cutting head:Dual-exit head with automatic-feed spool
- Battery compatibility:WORX 20V and 40V Power Share tools
Our verdict“Pick the WG183 if you already use WORX Power Share tools and want a 13-inch trimmer, rather than the lightest option in this group.”
HEYWORK 20V 12-Inch Cordless String Trimmer and Edger
The HEYWORK stands apart from the small-yard Cordless Electric String Trimmer by pairing its trimming-and-edging conversion with two larger-capacity 4.0 Ah batteries and eight replacement spools. That bundle may appeal to buyers who want supplies on hand and fewer pauses to restock line. Its 12-inch cutting width and 8,000 rpm motor put it in the compact-yard class, not the broad-coverage tier of the Husqvarna 320iL, whose 16-inch path is better suited to covering open ground. At 6.3 pounds, the HEYWORK is still manageable, and automatic feed avoids stopping to bump the spool. The main reservation is the missing usable runtime figure: the listed “40 years” battery-life entry is not a meaningful per-charge estimate. I’d treat this as a useful bundle, not a proven choice for long sessions.
Pros:- Switches between string trimming and edging
- Includes two 20V 4.0 Ah lithium-ion batteries
- Eight replacement spools are supplied
- Automatic line feed and adjustable grip support easier routine trimming
Cons:- No credible per-charge runtime is specified; the listed 40-year battery-life entry does not clarify runtime
- 12-inch cutting width covers less ground per pass than the Husqvarna 320iL’s 16-inch path
- At 6.3 pounds, it is heavier than the 5.3-pound small-yard trimmer
Best for: Small-yard owners who want a convertible trimmer and edger, multiple spare spools, and two higher-capacity batteries included.
Not ideal for: Buyers who need dependable runtime information or a wide cutting path for large lawns and extended trimming sessions.
- Model:G-DC2505-HY
- Power source:Battery powered
- Voltage:20 V
- Cutting width:12 inches
- Motor speed:8,000 rpm
- Weight:6.3 pounds
- Batteries included:Two 4.0 Ah lithium-ion batteries
- Line feed:Automatic
- Included accessories:Charger and eight replacement spools
Our verdict“Choose the HEYWORK for its battery-and-spool bundle and edging function, but not if you need a reliable runtime estimate before tackling a long job.”
Husqvarna 320iL Cordless String Trimmer with 4 Ah Battery and Charger
For buyers who want to cover more ground per pass, the Husqvarna 320iL earns its place with a 16-inch cutting width—four inches wider than the HEYWORK and small-yard picks. That wider path can reduce passes across open lawn, while the brushless motor and vibration reduction are aimed at more comfortable use. A dual-direction head gives control over which way clippings move, and Rapid Replace makes string loading less fussy than a conventional winding process. The included 40V, 4 Ah battery and charger mean it can be used out of the box, though the single battery still sets a limit on work between charges. Unlike the WORX WG183, this model does not come with a second battery or a stated cross-tool battery platform. I’d put it ahead for coverage and loading convenience, but not for buyers who prize the lightest setup or spare-battery flexibility.
Pros:- 16-inch cutting width covers more ground per pass than the other reviewed trimmers
- Brushless motor and vibration reduction are designed to support comfortable trimming
- Rapid Replace system simplifies string loading
- Includes a 40V 4 Ah battery and charger
Cons:- Only one battery is included, so longer sessions may require a recharge break
- At 7 pounds, it is heavier than the compact-yard options
- The supplied details do not state runtime for the included battery
Best for: Homeowners with medium or larger lawns who value a wide cutting path, easier line replacement, and a battery and charger included in the package.
Not ideal for: Owners of very small yards seeking a lighter tool, or buyers who need a spare battery included for longer uninterrupted sessions.
- Model:970480104
- Power source:Battery powered
- Cutting width:16 inches
- Battery:One 40V 4 Ah lithium-ion battery
- Motor:Brushless
- Weight:7 pounds
- Cutting head:Dual-direction
- String loading:Rapid Replace system
- Included:Battery and charger
Our verdict“Choose the 320iL for a wider cutting path and easier line loading, provided one included battery suits the length of your trimming sessions.”
WORKPRO 7.2V Cordless Grass Shear and Shrub Trimmer
This WORKPRO is a different kind of pick from the string trimmers here: its interchangeable shear and shrub blades suit precise edging and light shaping, not clearing long lawn borders. At just 0.82 pounds, it is much lighter than the WORX WG183 or Husqvarna 320iL, making one-handed detail work more manageable. The tradeoff is scale: its grass blade is only 4.17 inches wide, and the shrub blade is intended for small growth up to the listed 7.95 mm branch thickness. That makes it a useful companion for neat, small patches rather than a substitute for a 12- or 16-inch string trimmer. USB-C charging and tool-free blade changes add convenience, but the 2,000 mAh battery can need a recharge after extended storage or infrequent use. I’d choose it for delicate maintenance, and pair it with a full-size trimmer for general lawn edges.
Pros:- Very light 0.82-pound design supports one-handed detail work
- Interchangeable blades handle grass and small-shrub trimming
- USB-C charging works with common USB power sources
- Tool-free blade changes and dual safety locks are included
Cons:- The 4.17-inch grass blade is far narrower than the string-trimmer heads in this roundup
- Shrub blade is suited only to branches up to the listed 7.95 mm thickness
- Battery may need recharging after extended storage or infrequent use
Best for: Gardeners who maintain small grass borders and lightly shape compact shrubs, and who want a very light, one-handed cordless tool.
Not ideal for: People looking to trim lawn edges quickly, clear weeds, or cut branches thicker than the listed 7.95 mm limit.
- Model:W159029AE
- Voltage:7.2 V
- Battery capacity:2,000 mAh
- Weight:0.82 pounds
- Charging:USB-C; approximately 2–3 hours
- Shrub blade length:5.9 inches
- Grass blade width:4.17 inches
- Maximum branch thickness:7.95 mm
- Safety:Dual lock
Our verdict“Pick the WORKPRO for precise grass and small-shrub touch-ups, not as your main trimmer for ordinary lawn edges.”
BLACK+DECKER 14-Inch Electric String Trimmer (BESTE620)
The BESTE620 is my pick for buyers who want a straightforward, lightweight trimmer and have an outdoor outlet within reach. Its 14-inch cutting width covers more ground per pass than the Greenworks 40V 12-inch trimmer, while the 6.5-amp motor and POWERDRIVE transmission are aimed at grass, weeds, and overgrowth. EASYFEED advances line at a button press, avoiding the bump-feed routine; the tool also converts to a wheeled edger for tidier lawn borders. At 5.3 pounds, it is lighter than the cordless BLACK+DECKER LST136, though that model offers freedom from a cord. The main compromise is tethered operation: you need an outlet and must manage the cord around beds and obstacles. I’d choose this for regular, nearby lawn work, not for large or cord-free yards.
Pros:- 14-inch cutting width handles more ground per pass than the 12-inch Greenworks 40V model.
- EASYFEED advances the line with a button press rather than requiring bump feeding.
- Converts to a wheeled edger for controlled lawn borders.
- Light 5.3-pound body with adjustable handle and height.
Cons:- Requires a power cord and nearby outlet, limiting range and maneuverability.
- Cord management can be awkward around landscaping and obstacles.
Best for: Homeowners with small to medium lawns, an accessible outdoor outlet, and a preference for a light trimmer that can also edge.
Not ideal for: People trimming far from an outlet or working around many trees, beds, and obstacles where a power cord can restrict movement.
- Power source:Corded electric
- Motor:6.5 amp
- Cutting width:14 inches
- Weight:5.3 pounds
- Line feed:EASYFEED, button-operated
- Modes:String trimmer and wheeled edger
- Warranty:2-year limited warranty
Our verdict“Choose the BESTE620 for broad, routine trimming close to an outlet; pick the cordless BLACK+DECKER LST136 if freedom of movement matters more.”
Black+Decker 40V Max 13-in String Trimmer/Edger Cordless with Adjustable Telescoping Pole, 2-in-1 Weed Wacker Lawn Edger, Includes Battery and Charger (LST136)
The LST136 is the stronger fit for buyers who want one battery-powered tool for trimming and edging without managing an extension cord. Its 40V MAX battery and PowerDrive transmission support fast cutting, while the listed speed reaches 8,500 RPM. Unlike the corded BLACK+DECKER BESTE620, it can move freely around a yard; its automatic feed spool also advances line without bumping. The 13-inch path is slightly narrower than that corded model’s 14-inch cut, and at 7.8 pounds it weighs more than the BESTE620, which may matter during long sessions. The telescoping pole and soft-grip handle offer ways to adjust the fit, and conversion to edger adds flexibility. I’d favor it for medium yards without convenient outlet access, but not for buyers prioritizing the lightest tool.
Pros:- Cordless 40V MAX platform allows movement without an extension cord.
- PowerDrive transmission and listed 8,500 RPM speed support brisk cutting.
- Automatic feed spool advances line without bumping.
- Converts to an edger and has an adjustable telescoping pole.
Cons:- At 7.8 pounds, it is heavier than the corded BLACK+DECKER BESTE620.
- Its 13-inch cutting width is narrower than the BESTE620’s 14-inch path.
Best for: Homeowners with medium yards who want cordless trimming, automatic line feed, and a tool that can edge lawn borders.
Not ideal for: Buyers who need the lightest possible trimmer or want a wider cutting path; the 7.8-pound weight and 13-inch width are less appealing than the corded BESTE620’s figures.
- Voltage:40V MAX
- Battery:2.0 Ah lithium-ion, included
- Cutting width:13 inches
- Speed:Up to 8,500 RPM
- Weight:7.8 pounds
- Line feed:Automatic feed spool
- Warranty:3-year limited warranty
Our verdict“Pick the LST136 if cordless range and edging versatility matter more than the lighter weight and wider cut of the BESTE620.”
Greenworks 40V Cordless String Trimmer, 12-Inch, with 2.0 Ah Battery and Charger
The Greenworks 40V 12-inch trimmer is a sensible match for lighter yard maintenance where controlling pace matters more than covering a wide swath. Its variable speed control lets the operator dial back for careful work near plants or use more speed on open grass, while the auto-feed system handles line advancement without bumping. The included 2.0 Ah battery and charger make it a ready-to-use cordless kit, unlike a bare tool. Compared with the 13-inch BLACK+DECKER LST136, this Greenworks has a narrower path and a lower listed speed of 7,500 RPM, so it is less suited to quick coverage of larger areas. The product data describes a lightweight ergonomic design, though its listed weight is 12 pounds, a figure buyers should check against their handling needs. I’d reserve it for grass and light weeds rather than demanding overgrowth.
Pros:- Variable speed control helps adapt cutting pace to grass and nearby plants.
- Auto-feed line system advances line without bumping.
- Includes a 2.0 Ah battery and charger.
- Three-year limited warranty covers both tool and battery.
Cons:- The 12-inch cutting width requires more passes than the 13-inch BLACK+DECKER LST136.
- Product description is aimed at grass and light weeds, not heavy overgrowth.
- Listed weight is 12 pounds, which may feel substantial during longer sessions.
Best for: Owners of modest lawns who want cordless convenience and variable speed for trimming around delicate planting or mixed yard areas.
Not ideal for: People tackling large areas or tough, dense weeds who would benefit from a wider cut and stronger cutting pace, such as the BLACK+DECKER LST136 offers.
- Model:2101602
- Power source:Battery powered
- Voltage:40V
- Cutting width:12 inches
- Line system:0.065-inch dual line, auto feed
- Speed:7,500 RPM
- Battery:2.0 Ah lithium-ion, one included
- Weight:12 pounds
- Warranty:3-year limited warranty for tool and battery
Our verdict“Choose this Greenworks for controlled cordless trimming on lighter-duty lawns, but favor the BLACK+DECKER LST136 for faster coverage and more demanding work.”
Greenworks 24V 13-Inch Brushless String Trimmer with 4.0Ah Battery
This Greenworks stands out for combining a brushless motor and 13-inch cutting path with a notably light listed tool weight of 5.51 pounds without the battery. That makes it a compelling fit for buyers who want a more manageable trimmer than the 12-pound-listed Greenworks 40V model, while still getting a wider path than that model’s 12 inches. Automatic line feed and a trimmer-to-edger setup cover everyday lawn borders and touch-ups. The included 4.0 Ah battery, USB-C charger, cable, and plastic blades add flexibility, though the source information is inconsistent about the battery and charger inclusion, so I’d verify kit contents before buying. The plastic blades may also be less versatile than standard line for some trimming jobs. I’d choose it for lighter handling and routine yard care, not rough, heavy-duty clearing.
Pros:- Brushless motor paired with a 13-inch cutting path.
- Listed tool weight of 5.51 pounds without the battery supports easier handling.
- Automatic line feed and trimmer-to-edger modes cover two common lawn tasks.
- Compatible with the Greenworks 24V platform.
Cons:- Source information is inconsistent about whether the battery and charger are included.
- Plastic blades may not suit every trimming task.
- Battery-free listed weight does not reflect the full carry weight.
Best for: Buyers seeking a light 2-in-1 trimmer for routine grass and edging work, especially those already using Greenworks 24V tools.
Not ideal for: People clearing dense or woody growth, or anyone who needs confirmed kit contents and prefers conventional string over plastic blades.
- Voltage:24V
- Motor:Brushless
- Cutting width:13 inches
- Line diameter:0.080 inches
- Line feed:Automatic
- Weight:5.51 pounds without battery
- Battery:4.0 Ah; inclusion described inconsistently
- Charger:65W USB-C; inclusion described inconsistently
- Warranty:3 years
Our verdict“Pick this Greenworks for a light, brushless trimmer-and-edger setup, provided you confirm the kit contents and your work is not heavy-duty.”
24V Electric Weed Wacker Edger Lawn Tool with 2.0 Ah Batteries
This 24V tool takes a different approach from the string trimmers in this lineup: its five interchangeable blades are intended to handle soft grass, thicker weeds, and small branches, while a pivoting head and auxiliary wheel support edging and angled work. The adjustable 35–47-inch pole gives buyers a way to set reach without bending as much. At a listed 3 pounds, it is lighter than the BLACK+DECKER LST136, though its 6-inch cutting width is far narrower than that model’s 13-inch path and makes broad lawn trimming slower. Two 2.0 Ah batteries are listed, but the supplied information also warns that capacity may limit continuous work on very large properties. I’d choose it for varied spot jobs and edging rather than as a fast replacement for a full-width string trimmer.
Pros:- Five interchangeable blade types offer options for grass, weeds, and small branches.
- Adjustable 35–47-inch pole and pivoting head support angled trimming and edging.
- Listed 3-pound weight and auxiliary wheel support easier control.
- Two 2.0 Ah batteries are included according to the product data.
Cons:- The 6-inch cutting width is much narrower than the 13-inch BLACK+DECKER LST136.
- The product data notes that battery capacity may limit continuous runtime on very large properties.
- Interchangeable blades make this less like a conventional string trimmer for routine broad-area cutting.
Best for: Gardeners with mixed small-scale trimming needs who want interchangeable blades, adjustable reach, and a pivoting head for edges and slopes.
Not ideal for: People maintaining large lawns or regularly cutting wide stretches of grass; the 6-inch path will need many more passes than the BLACK+DECKER LST136.
- Power source:Battery powered
- Voltage:24V
- Motor power:650W
- Speed:11,000 RPM
- Cutting width:6 inches
- Batteries:Two 2.0 Ah batteries
- Blade types:Five interchangeable metal, saw, and plastic blades
- Pole length:Adjustable from 35 to 47 inches
- Weight:3 pounds
Our verdict“Choose this tool for varied, small-scale blade work and adjustable reach, but pick a wider string trimmer for covering a lawn efficiently.”
Glenvera 20V 12-Inch 2-in-1 Cordless String Trimmer and Lawn Edger
The Glenvera stands out among these 12-inch cordless options for including two 4.0Ah batteries, a useful setup for yard work that may outlast a single battery. It switches between trimming and edging, and its automatic line feed avoids the bumping routine required by some trimmers. At six pounds, it is also fairly light for a kit with this battery capacity. Compared with the WORX WG163, Glenvera includes higher-capacity batteries, while WORX is lighter and offers wheeled guidance for cleaner edging on slopes. The tradeoff is that Glenvera’s stated runtime is still up to 60 minutes, so extensive work may need a pause, and its 12-inch swath covers less ground per pass than wider models. I’d shortlist it for buyers who want a ready-to-use cordless kit and value battery capacity over edging wheels.
Pros:- Two included 20V 4.0Ah batteries offer more capacity than the WORX WG163’s 2.0Ah batteries.
- Converts between string trimming and lawn edging.
- Automatic line feed reduces manual line adjustment.
- Adjustable head and rotating handle support different trimming positions.
Cons:- Runtime is listed as up to 60 minutes, which may not cover bigger jobs.
- The 12-inch cutting width takes more passes than a wider trimmer.
Best for: Homeowners with small-to-medium yards who want two higher-capacity batteries included for trimming and edging without a cord.
Not ideal for: People maintaining large properties or cutting broad, dense areas who need a wider swath or longer uninterrupted runtime.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Motor speed:Up to 9,000 RPM
- Batteries included:Two 20V 4.0Ah batteries
- Runtime:Up to 60 minutes
- Weight:6 pounds
- Included accessories:Charger and 8 spool lines
Our verdict“Choose the Glenvera if you want a lightweight cordless trimmer-edger supplied with two higher-capacity batteries for routine yard care.”
WORX 20V 12″ 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
The WORX WG163 earns its place for homeowners who want more guidance when shaping borders, rather than simply the broadest cutting path. Its rubberized wheels and 90-degree tilting head help track a straight edge, including along sloped ground, while the tool converts quickly from trimming to edging. At 5.5 pounds, it is the lightest option in this five-product group. That makes it easier to maneuver than the Glenvera, though Glenvera’s two 4.0Ah batteries offer more capacity than the WORX pair of 2.0Ah batteries. The WORX’s 12-inch width suits detail work but means more passes across open ground, and the battery runtime may fall short for larger yards. I’d favor it for tidy borders and manageable lawns, not for long sessions or fast coverage.
Pros:- Rubberized wheels help guide straight edging cuts.
- A 90-degree tilting head supports edging on sloped terrain.
- At 5.5 pounds, it is lighter than the other listed trimmers in this batch.
- Includes two batteries, a charger, and an instant line-feed push button.
Cons:- The two 2.0Ah batteries may limit runtime on larger yards.
- The 12-inch cutting width requires extra passes over broad areas.
Best for: Gardeners with small-to-medium yards who want a lightweight cordless trimmer that can guide edging along sidewalks and sloped borders.
Not ideal for: People with large lawns or long trimming sessions who need extended runtime or a wider cutting path.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- No-load speed:7,600 RPM
- Line diameter:0.065 inches
- Batteries included:Two 20V 2.0Ah lithium-ion batteries
- Weight:5.5 pounds
- Edging features:Rubberized wheels and 90-degree tilting head
Our verdict“Pick the WORX WG163 for lightweight handling and wheel-guided edging, but choose the Glenvera if battery capacity matters more.”
WeGofly 13-Inch Cordless 4-in-1 String Trimmer
The WeGofly is the most versatile pick here: it combines trimming, edging, mini mowing, and brush cutting in one cordless tool. Its 13-inch cutting width is also broader than the 12-inch paths of the WORX WG163 and Glenvera, helping cover open ground with fewer passes. A listed 15,000-rpm brushless motor and two 21V 6.0Ah batteries make this the most ambitious kit in the group on paper, while the telescopic pole and adjustable head give it more setup flexibility. The tradeoff is added uncertainty: the product information conflicts on whether one or two batteries are included, so I’d verify the package contents before buying. Its multiple functions may also be unnecessary for someone who only needs basic line trimming. The three-year tool warranty and two-year battery warranty add a stated coverage advantage.
Pros:- Four listed functions cover more yard tasks than the 2-in-1 Glenvera and WORX models.
- The 13-inch cutting width is wider than those two 12-inch alternatives.
- Brushless motor is listed at 15,000 RPM.
- Includes adjustable components and has a stated three-year tool warranty.
Cons:- Battery information conflicts: the description says two batteries, while the product information lists one.
- The extra functions may add complexity for buyers who only need trimming and edging.
Best for: Homeowners who want one cordless tool for trimming, edging, light mowing, and brush-cutting tasks, and are willing to confirm battery contents.
Not ideal for: Buyers seeking a simple, clearly specified trimmer for routine grass edges, or anyone unwilling to verify the battery configuration.
- Power source:Battery powered
- Model:WEG21T
- Cutting width:13 inches
- Motor type:Brushless
- Motor speed:15,000 RPM
- Battery configuration:Description says two 21V 6.0Ah batteries; product information lists one
- Functions:String trimmer, lawn edger, mini lawn mower, brush cutter
- Weight:5.2 pounds
- Warranty:3 years for the tool; 2 years for batteries
Our verdict“Choose the WeGofly for its four-tool versatility, provided you confirm the number of batteries included before ordering.”
BLACK+DECKER BESTA510 14-Inch Electric String Trimmer and Lawn Edger
The BESTA510 is the only corded pick in this batch, and that changes the buying decision: it trades freedom of movement for continuous power without battery-runtime limits. Its 14-inch cutting width is wider than the 12-inch paths on the Glenvera and WORX WG163, so it can cover more ground per pass. The wheeled edger conversion and automatic feed spool also suit routine border work without bumping the head to advance line. At 6.3 pounds, it remains manageable to carry, but the cord restricts reach and can snag around trees, beds, and other obstacles. The cord retention system helps keep the connection secure; it does not remove the need for a nearby outlet and suitable extension cord. I’d choose it for accessible yards where steady power matters more than cordless convenience.
Pros:- 14-inch cutting width covers more ground per pass than the 12-inch Glenvera and WORX.
- Corded power avoids battery runtime limits.
- Converts to a wheeled lawn edger.

20V Cordless String Trimmer with Two 2.0Ah Batteries and Charger
This unnamed 20V trimmer is best distinguished by how it stores: its shaft folds 180 degrees, a practical advantage for buyers with limited garage or shed space. The adjustable head and handle support both trimming and edging, and automatic line feed keeps routine operation simple. Its 12-inch cutting width is similar to the WORX WG163, but the WORX offers wheel-guided edging that this model does not list. The two included 2.0Ah batteries provide up to 30 minutes of combined runtime, which places it behind the Glenvera’s stated up-to-60-minute runtime and makes it a better fit for quick maintenance than larger jobs. The product information also warns against excessively thick or dense grass, where line can break. I’d pick it for compact storage and short sessions, not heavy overgrowth.
Pros:- Folding shaft supports compact storage.
- Includes two 20V 2.0Ah lithium-ion batteries and a charger.
- Adjustable head and rotatable handle support trimming and edging positions.
- Automatic line feed avoids manual bumping.
Cons:- Up to 30 minutes of combined runtime may not cover longer jobs.
- Not suited to excessively thick or dense grass, where the line may break.
Best for: Apartment dwellers or homeowners with small yards and limited storage who need a foldable trimmer for short maintenance sessions.
Not ideal for: People with large yards, dense grass, or frequent heavy trimming who need longer runtime and greater cutting capacity.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Motor speed:9,500 RPM
- Batteries included:Two 2.0Ah lithium-ion batteries
- Combined runtime:Up to 30 minutes
- Line feed:Automatic
- Adjustments:90-degree head, 180-degree rotatable handle, and shaft that folds 180 degrees
Our verdict“Pick this model for a foldable, easy-to-store trimmer for brief yard maintenance, not for large or overgrown lawns.”
How We Picked
I compared these 15 trimmers around the jobs buyers actually need them to do: cleaning up lawn borders, cutting grass around obstacles, edging paths, or handling small patches of growth. I gave more weight to practical fit than to voltage labels alone, looking at cutting width, power source, battery and charger inclusion, stated battery capacity, and features that can make a tool easier to adapt or store. I also separated full-size string trimmers from compact grass-shear tools, since they are built for different workloads and should not be ranked as direct substitutes.
The order favors models with a convincing balance of capability, flexibility, and a ready-to-use power setup. A cordless tool with a supplied battery and charger can be easier to use across a yard, while corded options remain relevant for buyers who work near an outlet and want to avoid battery planning. Two-in-one and multi-function designs earn consideration for versatility, but added modes do not outweigh a mismatch with the buyer’s yard or trimming workload. Where the provided product information does not establish runtime, weight, or cutting results, I avoid treating those details as proven advantages.

Factors to Consider When Choosing Best Electric Grass Trimmers
Before choosing a model, match the tool to the work you repeat most often. A broad lawn, a few path edges, and fine trimming around beds call for different combinations of reach, runtime, and control.
Choose Cordless or Corded Based on Your Working Area
Cordless models make it easier to move around trees, fences, and separate lawn areas without managing an extension cord. Their limits depend on battery capacity, charge time, and whether a spare battery is included, so think about how long your typical session lasts rather than relying on voltage alone. A corded trimmer avoids mid-job battery charging, but its practical reach is set by the cord and outlet location. Extension cords also require care around the cutting line and can be awkward around obstacles. For a small yard near an outdoor outlet, corded can be a sensible choice; for scattered trimming locations, cordless usually offers simpler movement.
Read Battery Details as a Complete Setup
Battery voltage describes the tool’s electrical platform, not a guaranteed amount of runtime or cutting power. Amp-hour capacity gives another useful clue, but actual working time varies with growth, cutting technique, and how often the tool runs at full speed. Check whether the package includes a battery and charger, and whether it includes one battery or more than one. A second battery is most useful when you have enough work to outlast one charge and can swap batteries without waiting. Buyers already invested in a compatible battery platform should also check whether a bare tool would make better sense than paying for another charger.
Match Cutting Width and Tool Type to the Job
A wider cutting swath can cover open grass faster, but it may be less convenient in narrow borders or tight planting beds. Compact grass shears are meant for detailed, light trimming and cannot stand in for a full-size string trimmer on larger areas. For mixed jobs, a standard trimmer with an edging mode can replace some hand work along paths and borders. Do not buy a multi-function label alone: check which attachments or modes are included and whether they address tasks you actually do. If most of your work is edging, a design that switches cleanly between trimming and edging may matter more than maximum cutting width.
Prioritize Handling for the Places You Trim
Tool balance, shaft length, grip position, and adjustability affect comfort during repeated passes, even when product listings give more attention to voltage and cutting width. If you are shorter or taller than average, adjustable shafts and handles can help you keep the head at a workable angle. A heavier tool may feel manageable for a quick edge but tiring across a large perimeter. Check whether the tool has a guard and whether its layout gives you room to control the head around fences and garden beds. When possible, compare the tool’s stated weight with the battery attached, since the battery contributes to what you hold.
Know What Maintenance and Line Feeding Involve
String trimmers need replacement line, and the spool system affects how much attention the tool demands during yard work. Check the compatible line size, whether replacement spools are easy to find, and whether the feed is manual, bump-fed, or automatic. These systems trade convenience against control: automatic feeding reduces interruptions, while simpler systems may be easier to understand and maintain. Keep the guard clear of grass buildup and inspect the line before each session to avoid preventable stoppages. Compact shear tools use cutting blades rather than standard trimmer line, so their upkeep and best applications differ.
Pay for Capability You Will Actually Use
A more capable battery platform, brushless motor, or adjustable shaft can be worthwhile if you trim often, cover a large area, or want one tool for several lawn tasks. Those features bring less value to a small yard that needs only occasional touch-ups. Multi-function designs can reduce the need for separate tools, but only when the included functions fit your routine and do not add unwanted bulk. A corded model may be the better use of your budget if you have a nearby outlet and prefer not to buy batteries. Set your priority first—runtime, reach, edging, or compact storage—then compare models within that need instead of paying for a long feature list.
Frequently Asked Questions
Is a cordless electric trimmer powerful enough for a large yard?
It can be, but the yard’s size is only part of the decision. The amount and toughness of the growth, the length of your trimming sessions, and the battery setup all affect whether a cordless model keeps pace. Look at battery capacity and whether a second battery is supplied, but do not treat those details as exact runtime guarantees. For extensive trimming, plan for charging breaks or a compatible spare battery. If your work stays near an outdoor outlet, a corded tool may avoid battery interruptions, though the cord limits movement.
Should I choose a trimmer with one battery or two?
One battery is often enough for occasional edging and small cleanup jobs, especially if you can charge it between sessions. Two batteries are more useful when you have a longer route around the yard or want to keep working while one battery charges. Compare the capacity of each battery, not only the number included; two small packs do not automatically provide the same session length as one larger pack. Also check whether the charger is included and how quickly it can replenish a pack. If you already own compatible batteries, a package with extra batteries may not be the best fit.
Can a 2-in-1 trimmer and edger replace a separate lawn edger?
For routine cleanup along walkways and garden borders, a trimmer that converts to edging mode may be enough. It is a convenient fit for homeowners who want to switch between grass trimming and light edge maintenance without storing another tool. A dedicated edger may suit someone who wants a more specialized tool for frequent, sharply defined borders or tougher edging work. Before choosing a convertible model, check how it changes modes and whether the head can follow the edges you have. Its value depends on how often you edge, not just the number of functions listed.
Is a brushless electric trimmer worth choosing over a brushed model?
A brushless motor can be attractive to frequent users because it avoids motor brushes and is often designed for efficient operation. That does not make every brushless model the right choice: battery capacity, balance, cutting width, and the workload still shape the experience. For occasional trimming in a small yard, the added motor feature may matter less than a comfortable tool with a suitable power setup. For repeated or longer sessions, it may be a more relevant difference. Compare the complete tool and battery package rather than buying on motor type alone.
What should I buy if I only need to trim around beds and shrubs?
For small patches of grass and detail work around beds, a compact grass shear can be easier to control than a full-size string trimmer. It is not a substitute for clearing long borders, broad lawn edges, or heavier growth, so be realistic about the area involved. If your yard includes both detail work and ordinary trimming, a lightweight cordless string trimmer may cover more tasks. Consider storage space, battery inclusion, and the availability of replacement blades or line for the tool type. Choosing a full-size model just for a few small touch-ups can add bulk without adding much practical value.
Conclusion
For the broadest mix of cordless capability and a supplied 4 Ah battery setup, I recommend the Husqvarna 320iL as the best overall choice. My best value pick for buyers wanting one tool for trimming and edging is the WORX WG163; for buyers who prefer a corded setup near an outlet, the BLACK+DECKER BESTE620 is a practical alternative. The best premium direction is the Greenworks 24V brushless model for shoppers who value its motor design and included 4 Ah battery, while beginners may prefer a straightforward 2-in-1 design such as the HEYWORK 20V or WORX WG163. For specific needs, choose the WORKPRO 7.2V shear for light detail trimming, the BLACK+DECKER LST136 for an adjustable cordless trimmer-and-edger format, or a corded 14-inch model for steady work near power. Match the pick to your yard size and routine, and you will avoid paying for capability you do not use—or choosing a compact tool for work it was not built to handle.
