The best electric grass trimmers balance enough cutting power for your lawn with manageable weight, useful runtime, and easy edging. My best overall pick is the EGO POWER+ 15-Inch Cordless String Trimmer (ST1502SA), a strong choice for buyers who want a wider cutting path and a battery-and-charger kit. For a broader yard-care setup, the EGO Power+ Multi-Head Combo adds attachment flexibility, while the WORX WG163 stands out for trimming and edging in one tool. The main tradeoffs are corded convenience versus cordless freedom, wider cutting coverage versus control, and a bundled battery versus the ability to use batteries you already own. Read on for the full breakdown and help matching a trimmer to your yard.

Key Takeaways
- The EGO ST1502SA earns the overall lead by combining a 15-inch cutting path with a battery and charger, making it a more complete fit for regular yard work than narrow-path options.
- The EGO Multi-Head kit favors versatility: it suits buyers who may want to add compatible attachments, while a dedicated trimmer is the simpler choice if trimming is the only task.
- Edging is a major dividing line. The WORX WG163, Glenvera, BLACK+DECKER BESTA510, and HEYWORK combine trimming with edging, which can reduce tool changes along lawn borders.
- Battery details matter as much as voltage. Several cordless picks include a battery and charger, but buyers should compare capacity and existing tool compatibility rather than choosing by voltage alone.
- Corded BLACK+DECKER models trade range for simplicity: they avoid battery runtime limits, but a cord can restrict movement and requires planning around outlets and the work area.

More Details on Our Top Picks
Greenworks 40V 12-Inch String Trimmer and 390 CFM Blower Combo with 2.0 Ah Battery
I’d choose this Greenworks kit when trimming is only part of the yardwork: the included blower handles leaves and clippings without requiring a second tool purchase. Its automatic line feed avoids manual bumping, while the 12-inch cutting path is narrower than the 15-inch swaths on the EGO MST1501 and EGO ST1502SA. That makes it a more modest choice for clearing large, overgrown areas, but a practical fit for routine edging and spot trimming. The blower’s stated 390 CFM airflow and cruise control add useful cleanup flexibility. The main caveat is uncertainty in the supplied weight and battery-life claims, which conflict within the product details; I’d avoid relying on those figures when planning longer sessions.
Pros:- Includes both a string trimmer and a blower
- Automatic line feed reduces manual line adjustment
- Blower includes cruise control
- Includes a 2.0 Ah battery
Cons:- 12-inch cutting width is narrower than the EGO 15-inch trimmers
- Supplied battery-life claims conflict, so practical runtime is unclear
- Listed weight conflicts between product details and description
Best for: Homeowners who want one battery kit for routine trimming and blowing leaves or clippings around a small-to-medium yard.
Not ideal for: Buyers with large areas of dense growth who want a wider cutting path, or anyone who needs dependable, clearly stated weight and runtime figures.
- Power source:Battery powered
- Voltage:40V
- Trimmer cutting width:12 inches
- Trimmer line diameter:0.065 inches
- Blower airflow:390 CFM
- Blower air speed:110 mph
- Battery capacity:2.0 Ah
- Listed item weight:16.5 pounds
Our verdict“Choose this kit if a useful blower matters as much as a capable trimmer, but pick an EGO 15-inch model for wider trimming coverage.”
EGO Power+ MST1501 Multi-Head String Trimmer Combo Kit with 5.0Ah Battery and Charger
The MST1501 is the strongest fit here for buyers who want a multi-head platform rather than a trimmer alone. Its 15-inch attachment covers more ground per pass than the 12-inch Greenworks 40V trimmer, and the 5.0Ah battery gives this kit a larger stated capacity than the battery supplied with the EGO ST1502SA. A brushless motor, .095-inch line, and Rapid Reload head suit regular trimming where quick line replacement and a robust cutting setup matter. It also includes the power head, battery, and charger, so the kit is ready to use without sourcing those separately. The tradeoff is that its stated runtime is still up to 45 minutes, and the multi-head format adds little value if you only need a basic string trimmer.
Pros:- 15-inch cutting width covers more ground per pass than the 12-inch Greenworks combo
- Includes a 5.0Ah battery and standard charger
- Brushless motor and .095-inch line suit regular trimming
- Rapid Reload head simplifies line replacement
Cons:- Runtime is stated at up to 45 minutes per charge
- Additional compatible batteries are sold separately
- Multi-head format may be unnecessary for buyers who only want a trimmer
Best for: Homeowners building a compatible outdoor-tool collection who want a wide-cutting trimmer kit with a larger included battery.
Not ideal for: Buyers who only need a simple standalone trimmer, or who need more than the stated 45-minute runtime without swapping batteries.
- Power source:Battery powered
- Voltage:56V
- Battery:5.0Ah ARC Lithium, included
- Runtime:Up to 45 minutes
- Cutting width:15 inches
- Trimmer line:.095-inch professional-grade dual-twist line
- Motor:Brushless
- Weight:12 pounds
Our verdict“Pick the MST1501 if you value the multi-head platform and larger included battery; choose the simpler EGO ST1502SA if a standalone trimmer is enough.”
24V Cordless Weed Trimmer with Two 4.0Ah Batteries and Wheel
At a stated 3.5 pounds, this 24V model is the lightest clearly specified option in this group, making it appealing for quick jobs where arm fatigue matters more than covering ground fast. Its six-inch cutting width is far narrower than the 14-inch BLACK+DECKER BESTE620 or the 15-inch EGO models, so I’d treat it as a precision tool for borders and small patches, not the first choice for broad lawn edges. The five interchangeable blade types offer more task flexibility than the string-only EGO ST1502SA, and two 4.0Ah batteries allow a swap during longer sessions. The cost of that flexibility is a stated 4–6-hour charging time, plus conflicting weight information in the product details; its 40–60-minute working-time claim also deserves caution.
Pros:- Five interchangeable blade types support different light-duty trimming and edging tasks
- Includes two 4.0Ah batteries for swapping during work
- Adjustable 33–47-inch pole accommodates different reach needs
- Light stated weight suits short, frequent jobs
Cons:- Six-inch cutting width is much narrower than the 14-inch BLACK+DECKER BESTE620
- Charging takes a stated 4–6 hours
- Weight and runtime details are inconsistent
Best for: People with small yards, narrow borders, or light trimming needs who prioritize a light tool and multiple blade styles.
Not ideal for: Buyers tackling long lawn edges or dense weeds who need a wide cutting path and predictable recharge times.
- Power source:Battery powered
- Voltage:24V
- Batteries included:2
- Battery capacity:4.0Ah each
- Working time:40–60 minutes
- Cutting width:6 inches
- Blade types:5 interchangeable types
- Pole length:33–47 inches
- Listed item weight:3.5 pounds
Our verdict“Choose this lightweight model for small, varied trimming jobs, not for fast coverage across a large lawn.”
BLACK+DECKER 14-Inch Electric String Trimmer (BESTE620)
The BESTE620 is the straightforward choice for buyers who want to avoid battery runtime limits and charging. Its corded power keeps the tool ready near an outlet, while the 14-inch cutting width is broader than the Greenworks 40V’s 12 inches and close to the EGO trimmers’ 15-inch swaths. Push-button EASYFEED advances line without the bump-feed routine, and the head converts to a wheeled edger for more controlled lawn borders. At 5.3 pounds, it is also lighter on paper than the EGO MST1501. The main compromise is reach: unlike the cordless options, it depends on an outlet and extension cord, which can limit movement around trees, beds, and distant lawn edges.
Pros:- 14-inch cutting width exceeds the Greenworks 40V trimmer’s 12 inches
- Converts between string trimming and wheeled edging
- EASYFEED advances line with a button press
- Listed weight is 5.3 pounds
Cons:- Cord and outlet restrict movement compared with cordless EGO models
- Requires an extension cord for work beyond outlet reach
- Cord management can be awkward around obstacles
Best for: Homeowners with a small or medium yard, accessible outlets, and a preference for continuous corded power over battery charging.
Not ideal for: People trimming far from outlets, working around many obstacles, or wanting unrestricted cordless movement.
- Power source:Corded electric
- Motor:6.5 amp
- Cutting width:14 inches
- Weight:5.3 pounds
- Functions:String trimmer and wheeled edger
- Line feed:EASYFEED button
- Warranty:2-year limited warranty
Our verdict“Choose the BESTE620 for uninterrupted trimming and edging close to an outlet; go cordless if yard layout makes a cord cumbersome.”
EGO POWER+ 15-Inch Cordless String Trimmer with Battery and Charger (ST1502SA)
The ST1502SA makes the most sense for buyers who want a capable standalone cordless trimmer, not a multi-head kit. It matches the MST1501’s 15-inch cutting width and .095-inch line, but comes with a smaller 2.5Ah battery rather than the MST1501’s 5.0Ah pack. That keeps the setup lighter at a listed 7.4 pounds, while the brushless motor and Rapid Reload head address routine trimming and line replacement without requiring a separate power head. Its stated runtime is up to 45 minutes, and the supplied charger takes 50 minutes for a charge. Compared with the corded BLACK+DECKER BESTE620, this EGO offers more freedom of movement but still requires battery planning for longer sessions.
Pros:- 15-inch cutting width and .095-inch line suit regular yard trimming
- Includes a 2.5Ah battery and charger
- Rapid Reload head simplifies line replacement
- Compatible with EGO 56V ARC Lithium batteries
Cons:- Stated runtime is up to 45 minutes per charge
- Included 2.5Ah battery has lower capacity than the MST1501 kit’s 5.0Ah battery
- Cordless operation depends on a compatible EGO battery
Best for: Homeowners who want a wide-cutting cordless trimmer with battery and charger included, especially those already using EGO 56V batteries.
Not ideal for: Buyers who need longer uninterrupted sessions or prefer the larger included battery and multi-head flexibility of the EGO MST1501.
- Power source:Battery powered
- Cutting width:15 inches
- Cutting line diameter:0.095 inch
- Motor:Brushless
- Battery:2.5Ah lithium-ion, included
- Maximum runtime:Up to 45 minutes
- Battery charge time:50 minutes
- Weight:7.4 pounds
- Weather resistance:IPX4
Our verdict“Choose the ST1502SA for a lighter, ready-to-use EGO trimmer; choose the MST1501 if its larger battery and multi-head setup matter more.”
Husqvarna 320iL Cordless String Trimmer, 16-Inch, with 4 Ah Battery and Charger
The Husqvarna 320iL is the strongest fit here for buyers who want a wider cutting path and more power for thicker growth. Its 16-inch swath covers more ground per pass than the 12-inch WORX WG163 and Greenworks ST1232, while the brushless motor and boost mode give extra help when grass gets dense. The included 40V battery and charger make it a ready-to-use kit, and the dual-direction head helps direct clippings instead of scattering them unpredictably. LowVib technology is a useful comfort feature for longer sessions.
The tradeoff is that this is a trimmer-first choice, not the convertible edging tool the WORX offers. Its larger cutting width also suits open lawn edges better than cramped beds and tight corners. I’d choose it for demanding routine trimming, but skip it if easy edging conversion matters more than cutting capacity.
Pros:- 16-inch cutting width covers more ground per pass than the 12-inch models in this group
- Brushless motor with boost mode adds power for heavier grass and weeds
- 40V 4 Ah battery and charger are included
- Dual-direction head helps control the direction of clippings
Cons:- Does not offer the dedicated trimmer-to-edger conversion of the WORX WG163
- Larger cutting width can be less convenient around tight garden borders
- Battery appearance may vary
Best for: Homeowners with medium-to-large yards, thicker grass, and enough open edging to benefit from a 16-inch cutting path
Not ideal for: Buyers who mainly need a compact trimmer-edger for tight borders or want a listed wheel-supported edging setup
- Power source:Battery powered
- Battery:40V lithium-ion, 4 Ah; one included
- Charger:Included
- Cutting width:16 inches
- Weight:7 pounds
- Motor:Brushless
- Trimmer head:Dual-direction; Rapid Replace
- Power boost:Up to 20% more power
Our verdict“Choose the Husqvarna 320iL for wider, more demanding trimming; pick the WORX WG163 instead if edging versatility is your priority.”
WORX WG163 20V 12-Inch Cordless String Trimmer and Lawn Edger
The WORX WG163 earns its place as the most edging-focused pick in this group. It changes from string trimmer to lawn edger, and its tilting head and support wheels help guide a straighter cut along uneven borders. That makes it more practical for lawns where crisp edges matter as much as trimming; the Husqvarna 320iL offers a wider 16-inch path and more power-oriented features, but not the same listed two-in-one setup. Two included batteries also give you a spare to swap in rather than stopping to recharge.
The 12-inch cutting width means more passes across open areas than with the Husqvarna, and the 0.065-inch line points to routine residential work rather than heavy clearing. At 5.5 pounds, it is easier to maneuver than the 7-pound Husqvarna, though buyers focused on maximum cutting capacity should look elsewhere. I’d favor it for maintaining lawn borders, not tackling large patches of overgrowth.
Pros:- Converts between string trimming and lawn edging
- Tilting head and support wheels assist with edging uneven terrain
- Includes two 20V batteries and a charger
- Push-button line feed avoids manual line adjustment
Cons:- 12-inch cutting width takes more passes than the Husqvarna 320iL’s 16-inch path
- 0.065-inch line is better suited to routine trimming than heavy growth
- Listed dimensions omit a third measurement
Best for: Homeowners who regularly trim and edge lawn borders, especially where paths and garden edges are uneven
Not ideal for: Buyers with large areas of thick weeds who want a wider cutting path and more heavy-growth capacity
- Power source:Battery powered
- Battery voltage:20V
- Batteries included:Two lithium-ion batteries
- Cutting width:12 inches
- No-load speed:7,600 rpm
- Weight:5.5 pounds
- Line diameter:0.065 inches
- Functions:String trimmer and lawn edger
Our verdict“Pick the WORX WG163 if easy, guided edging is central to your yard work, rather than maximum cutting width.”
Glenvera 20V 12-Inch 2-in-1 Cordless String Trimmer and Lawn Edger
The Glenvera 20V stands out for adjustability and its included battery capacity, rather than for covering the most ground. It combines trimming and edging with a four-position adjustable head and a handle that rotates 180 degrees, giving gardeners more ways to work around beds and borders. Its two 4.0 Ah batteries are a larger stated capacity than the pair supplied with the 21V Cordless Electric String Trimmer, whose runtime figures also conflict. Glenvera lists up to 60 minutes of runtime, though that figure is a claim rather than a guarantee for every yard.
The 12-inch cutting width is narrower than the Husqvarna 320iL’s 16-inch path, so larger lawns call for more passes. Automatic line feed keeps routine work simple, but the extra flexibility may matter less to buyers with straightforward, open edges. I’d choose it for varied garden layouts and skip it if speed across broad areas is the priority.
Pros:- Combines string trimming and lawn edging
- Two included 20V 4.0 Ah batteries provide substantial listed capacity
- Automatic line feed reduces manual adjustments
- Four-position head and 180-degree rotating handle support flexible positioning
Cons:- 12-inch cutting width requires more passes across larger areas
- Up to 60 minutes is an advertised runtime, not a guaranteed working time
- Offers less cutting width than the Husqvarna 320iL
Best for: Gardeners with varied beds, borders, and edging angles who want two included batteries and adjustable handling
Not ideal for: Owners of larger open lawns who would benefit more from the Husqvarna 320iL’s wider cutting path
- Voltage:20V
- Functions:String trimmer and lawn edger
- Cutting width:12 inches
- Motor speed:Up to 9,000 RPM
- Battery capacity:Two 20V 4.0 Ah batteries
- Runtime:Up to 60 minutes
- Line feed:Automatic
- Weight:6 pounds
Our verdict“Choose Glenvera for adjustable handling around varied garden borders, but favor a wider-cutting model for large open lawns.”
Greenworks 24V Cordless String Trimmer, 12-Inch Cutting Path, 2.0Ah Battery and Charger
At 4.08 pounds without the battery, the Greenworks ST1232 is the lightest option in this batch by its listed weight, making it a sensible choice for quick maintenance and buyers who want less tool weight to manage. Its brushless motor and auto-feed line system add useful convenience without pushing it toward heavy-duty claims. Unlike the WORX WG163, it is presented as a trimmer rather than a trimmer-edger conversion, so its appeal is straightforward grass and light-weed cleanup. The adjustable three-piece shaft also gives buyers some flexibility in fit and storage.
The included 2.0 Ah battery is smaller than the two 4.0 Ah batteries supplied with the Glenvera, and Greenworks describes this model for lighter growth. That limits its appeal for long sessions or dense weeds. The USB-C charger and three-year tool and battery warranty are practical extras, but don’t change its light-duty role. I’d choose it for short, frequent trims and avoid it for overgrown areas.
Pros:- Light listed weight of 4.08 pounds without the battery
- Brushless motor and auto-feed line system
- Adjustable three-piece shaft supports fit and storage
- Includes a 2.0 Ah battery, USB-C charger, cable, and three-year tool and battery warranty
Cons:- Designed for grass and light weeds rather than heavier growth
- 12-inch cutting path is narrower than the Husqvarna 320iL’s 16-inch path
- Includes one 2.0 Ah battery, less stated capacity than the Glenvera’s two 4.0 Ah batteries
Best for: Buyers seeking a lightweight cordless trimmer for short sessions on small lawns with grass and light weeds
Not ideal for: Homeowners who routinely cut dense weeds, need extended runtime, or want a built-in edging conversion
- Voltage:24V
- Cutting path:12 inches
- Line diameter:0.065 inches
- Motor:Brushless
- Line feed:Auto-feed
- Weight:4.08 pounds without battery
- Battery and charger:One 2.0 Ah battery; 30W USB-C charger
- Warranty:Three years for tool and battery
Our verdict“Choose the Greenworks ST1232 for light, frequent trimming where low tool weight matters more than runtime or heavy-growth power.”
Cordless Electric String Trimmer, 21V, 12-Inch Cutting Width
This 21V cordless trimmer makes the most sense for compact yards and brief cleanup jobs, where its 5.3-pound weight and trimming-to-edging conversion are more useful than sustained runtime. It includes two 2.0 Ah batteries, a charger, goggles, and a safety guard, so buyers get a ready-to-use set of basic accessories. Compared with the WORX WG163, it also offers a two-in-one layout, but the WORX lists support wheels for edging uneven ground. The Glenvera is a better match for buyers who want larger-capacity included batteries and more adjustable head positioning.
The main drawback is the runtime information: one figure says approximately 15–20 minutes per charge, while another lists 12 minutes on average. Either way, this is not a strong choice for prolonged trimming. Its 12-inch cutting width suits small areas, but larger lawns mean more passes and more battery changes. I’d reserve it for everyday garden touch-ups rather than neglected or expansive lawns.
Pros:- Trimmer converts for lawn edging
- Light listed weight of 5.3 pounds and adjustable handle
- Includes two 2.0 Ah batteries, charger, goggles, and safety guard
- Automatic line feed and tool-free assembly
Cons:- Runtime figures conflict: approximately 15–20 minutes per charge and 12 minutes average are both listed
- 12-inch cutting width requires more passes on larger lawns
- Less suitable for extended sessions than the Glenvera’s listed two 4.0 Ah batteries
Best for: Owners of small yards who want a light trimmer-edger kit for short maintenance sessions and basic safety accessories
Not ideal for: Buyers with larger lawns or long trimming sessions who need dependable extended runtime
- Power source:Battery powered
- Voltage:21V
- Motor speed:9,000 RPM
- Cutting width:12 inches
- Batteries included:Two 2.0 Ah lithium batteries
- Runtime:Approximately 15–20 minutes per charge; also lists 12 minutes average battery life
- Weight:5.3 pounds
- Functions:String trimming and lawn edging
Our verdict“Choose this model for quick trimming and edging in a small yard, but skip it if your work routinely lasts beyond a short battery session.”
ALSO GO 24V Cordless 3-in-1 Weed Trimmer, Edger, and Brush Cutter
The ALSO GO stands out for buyers who want more than a string trimmer: its three cutting functions and five interchangeable blades let it tackle grass, edging, and thicker weeds with one tool. The 35–47-inch adjustable shaft and pivoting head help adapt it to different users and angles, while the auxiliary wheel can steady edging passes. Compared with the BLACK+DECKER BESTA510, it offers cordless freedom and blade options for rougher growth, but its 6-inch cutting width covers far less ground per pass than that model’s 14-inch path. Two batteries are included, though their 2.0Ah capacity and unspecified runtime make it harder to plan longer sessions. I’d choose it for varied small-yard tasks, not broad lawn coverage.
Pros:- Three functions and five blade types suit varied yard tasks.
- Two batteries are included for swapping during work.
- Adjustable shaft and pivoting head accommodate different reach and cutting angles.
- Three-pound listed weight and auxiliary wheel support lighter, steadier handling.
Cons:- The 6-inch cutting width is narrow compared with 12- and 14-inch trimmers.
- Battery runtime is not specified, making session planning difficult.
- Multiple blade types add setup choices compared with a straightforward string trimmer.
Best for: Homeowners with small yards, mixed trimming and edging tasks, and patches of thicker weeds who value cordless operation and multiple blade options.
Not ideal for: People maintaining broad lawn edges or large overgrown areas, since the 6-inch cutting width means more passes and runtime is unspecified.
- Power source:Battery powered
- Motor power:650W
- No-load speed:11,000 rpm
- Battery:Two 24V 2.0Ah lithium batteries
- Cutting width:6 inches
- Shaft length:Adjustable from 35 to 47 inches
- Blades:Five interchangeable blades
- Functions:Brush cutter, lawn edger, and grass trimmer
- Weight:3 pounds
Our verdict“Choose the ALSO GO for compact yards with mixed grass and tougher weeds, but pick a wider-cutting model for faster coverage.”
BLACK+DECKER BESTA510 14-Inch 2-in-1 Electric String Trimmer and Lawn Edger
For buyers who can work within reach of an outlet, the BESTA510 pairs a 14-inch cutting path with a 6.5-amp motor, making it better suited to covering lawn edges and ordinary overgrowth than the narrow-cutting ALSO GO. Its head rotates for wheeled edging, and Automatic Feed Spool advances line without the bumping required by some trimmers. The adjustable handle and height positions help tailor the grip, while cord retention reduces the chance of an accidental unplug. The tradeoff is the cord itself: it limits range and calls for careful management around beds and obstacles. Unlike the cordless HEYWORK, this model does not depend on battery runtime, but it cannot roam freely around a yard. I’d favor it for regular trimming near accessible outlets.
Pros:- 14-inch cutting path covers more ground per pass than the ALSO GO’s 6-inch path.
- Rotating head and auxiliary wheel support wheeled edging.
- Automatic Feed Spool advances line without bumping.
- Adjustable handle and height positions help tailor the fit.
Cons:- The power cord restricts working range and requires active management.
- A 14-inch path may still need multiple passes across wider areas.
- Outlet access is required throughout the job.
Best for: Homeowners with small or medium yards, accessible outdoor outlets, and lawn borders who want a wider cut without managing batteries.
Not ideal for: People trimming far from an outlet, working around many obstacles, or wanting unrestricted cordless movement.
- Power source:Corded electric
- Motor:6.5 amp
- Cutting width:14 inches
- Speed:8,000 rpm
- Weight:6.3 pounds
- Modes:String trimming and lawn edging
- Line feed:Automatic Feed Spool
- Warranty:2-year limited warranty
Our verdict“Pick the BESTA510 if you have nearby outlet access and want a broad cutting path with simple edging conversion.”
HEYWORK 20V 12-Inch Cordless String Trimmer and Edger
The HEYWORK is a straightforward cordless choice for routine grass trimming and edging, with a 12-inch cutting width that offers more coverage per pass than the ALSO GO while keeping the tool focused on string-line tasks. Its automatic line feed removes the need to bump the head, and switching between trimming and edging makes it practical for maintaining borders. The kit includes two 20V 4.0Ah batteries, a charger, and eight replacement spools, giving buyers supplies for ongoing upkeep. Compared with the corded BLACK+DECKER BESTA510, it is easier to move around beds and yard boundaries, but battery runtime is not stated, so the included batteries do not guarantee a particular work session. This is a better fit for regular, lighter maintenance than tackling thick brush.
Pros:- Cordless operation avoids the outlet and cord restrictions of the BLACK+DECKER BESTA510.
- 12-inch cutting width is broader than the ALSO GO’s 6-inch path.
- Automatic line feed avoids manual bumping.
- Includes two 20V 4.0Ah batteries, a charger, and eight replacement spools.
Cons:- Battery runtime is not specified.
- String-trimming and edging functions are less suited to thick brush than the ALSO GO’s blade options.
- At 6.3 pounds, it is not lighter than the listed corded BLACK+DECKER BESTA510.
Best for: Homeowners who want cordless freedom for routine grass trimming and edging, with spare batteries and replacement spools included.
Not ideal for: Buyers tackling thick brush or planning long sessions who need documented runtime or a brush-cutting blade option.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Motor speed:8,000 RPM
- Weight:6.3 pounds
- Batteries included:Two 20V 4.0Ah lithium-ion batteries
- Included accessories:Charger and eight replacement spools
- Line feed:Automatic
- Modes:Trimming and edging
Our verdict“Choose the HEYWORK for cordless routine trimming and edging with extra batteries and spools, but not for brush cutting or runtime certainty.”
How We Picked
I compared the 13 listed trimmers by how well each fits common lawn jobs: trimming grass around obstacles, maintaining lawn edges, and handling longer sessions without adding unnecessary effort. I considered cutting-path width, power source, included battery and charger, multi-function design, and whether the product is a dedicated trimmer or part of a broader tool system. These factors shape real buying decisions more than a long feature list alone.
The ranking gives priority to a useful balance of cutting coverage, kit completeness, and flexibility. That puts the EGO ST1502SA first for buyers seeking a capable cordless trimmer in a ready-to-use kit, while the EGO Multi-Head ranks as a better fit for attachment versatility. Multi-function edging models rank well for smaller, detail-focused yards; corded models make sense for buyers who prefer not to manage battery runtime. Compact and lesser-specified cordless options remain relevant for light-duty needs, but their listed details provide less basis for choosing them over better-defined kits.

Factors to Consider When Choosing Best Electric Grass Trimmers
Before choosing a trimmer, I would match the tool to the shape of the yard and the way you already handle other outdoor equipment. A trimmer for quick touch-ups around a small lawn has different needs from one expected to cover long borders or serve as part of a multi-tool system.
Match Cutting Width to the Work
A wider cutting path covers more ground with each pass, which can reduce time on long fence lines and open lawn edges. A narrower path can feel easier to control around flower beds, trees, and tight corners, where accidental contact matters more than speed. Do not treat cutting width as a direct measure of cutting power; line type, motor design, and the grass being cut also affect performance. For a yard with mixed open and delicate areas, handling and balance may matter more than choosing the widest head. If most of your work is careful trimming, a compact option may be a better match than a wider model.
Choose Corded or Cordless Around Your Yard Layout
A corded trimmer avoids recharging and battery replacement, but the cord can limit reach and catch on shrubs or outdoor furniture. It suits a smaller area with accessible outlets and a clear route for the cable. Cordless models remove that tether and are easier to carry around obstacles, though runtime depends on battery capacity, cutting conditions, and how continuously you work. Buyers often focus on voltage while overlooking whether a battery and charger are included. If you already own compatible batteries, a tool-only purchase may fit your setup; if not, compare the full kit before deciding.
Think Beyond the Battery Voltage
Voltage is only one part of a cordless trimmer’s battery story. Capacity, battery condition, workload, and compatibility with other tools all affect how useful a pack will be over time. A kit with a larger battery may be more suitable for extended sessions, while a smaller pack can reduce carried weight for quick maintenance. Check whether the charger is included and whether replacement batteries belong to a tool platform you plan to keep using. Avoid assuming that two batteries with similar voltage will work across different brands or product systems.
Decide Whether Edging and Attachments Will Get Used
A trimmer that converts to an edger can save storage space and make border maintenance simpler, but conversion features only add value if you regularly maintain defined lawn edges. Some buyers may prefer a dedicated trimmer because fewer functions can mean a more straightforward tool to handle and store. A multi-head system makes more sense when you expect to add compatible attachments for other yard jobs. Before choosing a convertible or attachment-ready model, check how it changes between modes and whether the extra parts are included or sold separately. Buying versatility for tasks you rarely do can add complexity without improving routine trimming.
Account for Comfort and Control
Trimming can involve repeated sweeping motions, so weight distribution and grip adjustment can influence comfort over a full session. A tool that feels manageable near the handle may still feel tiring if its cutting head is heavy or the shaft is poorly balanced for your height. Wheels and guide features can help with steady edging, but they may be less useful when trimming around irregular obstacles. If possible, check the product’s weight and whether the handle or shaft adjusts before choosing based on cutting width alone. Buyers with many tight areas should prioritize control, while open yards may reward longer reach and wider coverage.
Plan for Line and Ongoing Maintenance
String trimmers rely on line that wears down or breaks, so line replacement is part of normal ownership. Check the compatible line diameter and how the head feeds or reloads it; a simple loading process can save time across repeated jobs. A bump-feed head may suit users comfortable advancing line while working, while other feed designs can reduce that interruption. Keep spare line available and avoid using a trimmer for stems or brush beyond its intended capacity. For heavier growth, a dedicated brush-cutting tool or a suitable attachment is a safer match than forcing a light-duty head through dense material.
Frequently Asked Questions
Is the EGO ST1502SA a better choice than the EGO Multi-Head kit?
I would choose the ST1502SA if trimming is the main job and you want a cordless kit with a 15-inch cutting path, battery, and charger. The Multi-Head kit makes more sense if compatible attachments are part of your yard-care plan, since its value comes from doing more than trimming. A dedicated trimmer is usually the simpler purchase when you do not need that expandability. Compare the included battery and the tools you may add before deciding. The right pick depends on whether you want a focused trimmer or a system that can grow.
Should I choose a corded trimmer or a cordless one for a small lawn?
A corded model can suit a small lawn if an outlet is close and the cable can reach the full work area without crossing a troublesome path. It avoids battery charging and runtime planning, but the cord can snag on landscaping or limit movement. Cordless models are easier to maneuver around trees and borders, even on a modest property, though they need a charged battery. Think about the layout, not only the size of the lawn. A compact yard with many obstacles can favor cordless convenience over corded operation.
Is a 2-in-1 trimmer and edger worth choosing over a dedicated trimmer?
A 2-in-1 model is useful if you regularly maintain clean edges along paths, driveways, or garden borders and want one tool for both jobs. The conversion feature is less compelling if you mostly trim around obstacles or let lawn edges remain informal. A dedicated trimmer may be the more straightforward choice for buyers who do not need edging. Check how the tool changes modes and how comfortable it is in each position. Do not assume that an edger function replaces a dedicated edging tool for every kind of border.
How much should I value an included battery and charger?
An included battery and charger matter most when you are buying your first tool in a cordless system. They let you use the trimmer without separately sourcing core parts and make kit comparisons more meaningful. If you already own compatible batteries and a charger, a tool-only option may avoid duplicate equipment. Confirm compatibility rather than relying on similar voltage labels, since battery platforms are brand-specific. Also compare battery capacity with your expected work session instead of treating every included pack as equivalent.
Can a lightweight cordless trimmer handle brush and thick weeds?
Lightweight cordless trimmers are generally better suited to lawn grass and routine edging than dense, woody growth. Their limits depend on the cutting head, line, and motor, so a voltage number alone cannot promise brush-cutting ability. The ALSO GO is listed as a 3-in-1 option that includes a brush-cutter function, but buyers should check its included cutting components and intended use before tackling heavy growth. For frequent thick brush, a dedicated brush cutter may be a better tool. Using a grass-trimmer head beyond its design can wear line quickly and reduce control.
Conclusion
For most buyers seeking a capable cordless tool in a ready-to-use kit, I recommend the EGO POWER+ ST1502SA as best overall. The Greenworks 24V trimmer is my value-minded choice for straightforward maintenance, while the EGO Multi-Head kit is the premium pick for buyers who plan to use compatible attachments. Beginners who want a simple way to trim and edge can start with the WORX WG163; buyers who prefer to avoid battery runtime limits should look at the BLACK+DECKER BESTA510 corded model. For combined trimming, edging, and brush-cutting functions, consider the ALSO GO 24V, after checking that its cutting setup suits the material you need to clear. Choose by yard layout and intended workload first, then compare battery setup, cutting width, and added functions.
