The best electric grass trimmers balance cutting reach, comfortable handling, and practical power for your yard. My best overall pick is the Husqvarna WeedEater 320iL, with its 16-inch cutting width and included 4 Ah battery; the BLACK+DECKER 20V 2-in-1 stands out for straightforward edging, while the Milwaukee 2825-20ST suits buyers who want a brushless tool with attachment capability. The main tradeoffs are cordless freedom versus corded runtime, a wider cut versus easier handling, and simple trimming versus extra functions that add weight or complexity. Battery systems and replacement-line arrangements also affect long-term convenience. Read on for the full breakdown and advice on matching a trimmer to your lawn.

Key Takeaways
- The Husqvarna WeedEater 320iL leads on cutting width and included battery capacity: Its 16-inch head and 4 Ah battery make it the strongest fit here for larger trimming areas, though its reach and battery package may be more than a compact yard needs.
- The lineup divides sharply between corded simplicity and cordless mobility: BLACK+DECKER‘s 4-amp corded model avoids battery-runtime limits, while most other picks trade continuous power for freedom to move.
- Multi-function labels do not mean every tool is equally versatile: The WORX WG170 adds a mini-mower mode, and the Milwaukee accepts attachments; buyers should favor functions they will actually use.
- Battery details matter as much as voltage: Several listings include batteries and chargers, but the pack capacity and whether two batteries are supplied affect how much uninterrupted work buyers can expect.
- Width and convenience involve tradeoffs: The 14- and 16-inch options can cover ground faster, while 12-inch models are easier to place around beds and tight edges; auto-feed can reduce line adjustments but does not remove maintenance.

More Details on Our Top Picks
BLACK+DECKER 20V MAX String Trimmer and Edger 2-in-1
At 5.7 pounds, this BLACK+DECKER is a manageable pick for routine trimming around beds, fences, and walkways. Its 2-in-1 design switches between trimming and edging, while automatic spool feed avoids the bumping technique required by some line-feed systems. Compared with the WORX WG163, it offers a similar 12-inch cutting width but a lower stated speed and a simpler setup; the WORX includes two batteries, while this kit comes with one.
That single battery and the 12-inch swath suit smaller yards better than long sessions across a large lawn. Mode changes are manual, and the plastic components may be less reassuring for frequent heavy-duty work. I’d choose it for easy handling and straightforward edging, not for maximum runtime or rugged construction.
Pros:- Lightweight 5.7-pound design is easier to handle around garden edges.
- Converts between trimming and edging for two common lawn tasks.
- Automatic spool feed reduces the need for manual line bumping.
- Battery and charger are included.
Cons:- One included battery may limit work time on larger yards.
- Manual mode switching interrupts work when changing between trimming and edging.
- Plastic components may be less suited to frequent rough use.
Best for: Homeowners with small to medium yards who want a lightweight cordless trimmer for routine edging and touch-ups.
Not ideal for: People with large properties or demanding, extended trimming sessions who need longer runtime or a wider cutting path.
- Power source:Battery powered
- Cutting width:12 inches
- Speed:6,200 rpm
- Battery:One lithium-ion battery included
- Weight:5.7 pounds
- Dimensions:36.23 inches long x 8.5 inches wide
- Warranty:2-year limited warranty
Our verdict“Choose this BLACK+DECKER for light, everyday cordless trimming when easy handling matters more than extended runtime.”
WORX 20V 12-Inch 3-in-1 Cordless String Trimmer, Edger, and Mini Mower WG170
The WG170 is the most adaptable pick here: it works as a string trimmer, edger, and mini mower, making it useful for lawn borders and small patches a full-size mower may miss. Its rotating head and adjustable handle add flexibility, while the two included batteries give it a runtime advantage over the one-battery BLACK+DECKER 20V MAX kit. The stated 7,600 rpm speed also exceeds that BLACK+DECKER’s 6,200 rpm.
This extra versatility comes with a tradeoff: the product data lists a five-hour charging time, and its broad listed dimensions may make storage less convenient. At 5.5 pounds, it is not heavier than the competing WORX WG163, but multiple modes may be unnecessary for someone who only trims edges. I’d pick it for varied small-yard tasks, not for fast charging or large-lawn coverage.
Pros:- Three functions cover trimming, edging, and mini mowing.
- Two included batteries provide a spare for continued work.
- Adjustable handle and rotating head support different working positions.
- Listed speed of 7,600 rpm is higher than the BLACK+DECKER 20V MAX kit’s stated speed.
Cons:- Listed charging time is five hours.
- The 12-inch cutting width is modest for covering broad areas.
- Multiple functions add complexity for buyers who only need trimming.
Best for: Owners of small yards who want one cordless tool for trimming, edging, and cutting modest patches of grass.
Not ideal for: Buyers who only need a basic trimmer, want short charging intervals, or regularly maintain large lawns.
- Power source:Battery powered
- Cutting width:12 inches
- Speed:7,600 rpm
- Batteries:Two lithium-ion batteries included
- Weight:5.5 pounds
- Functions:String trimmer, edger, and mini mower
- Charging time:5 hours
- Dimensions:45.1 inches long x 37.4 inches wide
Our verdict“Pick the WG170 if you’ll use its mini-mower and edging modes as well as its trimmer, and can work around the long listed charging time.”
WORX 20V 12-Inch 2-in-1 Cordless String Trimmer & Edger WG163
The WG163 focuses on the two jobs many homeowners need most: trimming and edging. Its head converts between modes, and rubberized support wheels help guide the tool along a lawn border for straighter edging. At 5.5 pounds, it is the lightest listed cordless option in this group, tying the WORX WG170 while skipping that model’s mini-mower function. Two included batteries also give it a practical advantage over the single-battery BLACK+DECKER 20V MAX.
The tradeoff is a 12-inch cutting width, which means more passes than a wider trimmer for open areas, and battery runtime may still fall short on large properties. Its PowerShare battery compatibility is useful if you already own compatible WORX tools, but less compelling otherwise. I’d choose it over the WG170 when guided edging matters more than a third function.
Pros:- Converts between trimming and edging.
- Rubberized support wheels help guide edging along borders.
- Two lithium-ion batteries are included.
- At 5.5 pounds, it is easy to maneuver for a cordless model.
Cons:- The 12-inch cutting width requires more passes over broad areas.
- Battery runtime may not suit large yards.
- The battery platform is most useful to buyers with compatible WORX PowerShare tools.
Best for: Cordless-tool owners who want a light trimmer with guided edging and a spare battery for smaller or medium yards.
Not ideal for: People trimming large open areas who prioritize a wider cutting path or need a tool for mowing as well as edging.
- Power source:Battery powered
- Cutting width:12 inches
- Speed:7,600 rpm
- Batteries:Two lithium-ion batteries included
- Weight:5.5 pounds
- Functions:String trimmer and edger
- Battery platform:WORX PowerShare
Our verdict“Choose the WG163 for lightweight cordless trimming with guided edging, especially if you already use WORX PowerShare batteries.”
20V 12-inch Cordless String Trimmer, Weed Wacker & Edger
This 20V trimmer’s bundle is its clearest distinction: it includes two 4.0Ah batteries and eight replacement spools, plus auto line feed and a 2-in-1 trimming-and-edging setup. That gives buyers more ready-to-use line and a spare battery, unlike the one-battery BLACK+DECKER 20V MAX kit. Its stated 8,000 rpm is also higher than either WORX model’s listed speed, though speed alone does not establish cutting performance.
The 12-inch width keeps it aimed at routine yard maintenance rather than fast coverage across large lawns. Battery life varies with use, and the supplied data does not give a runtime figure; I would not rely on the unusual “40 years” battery-life listing as a usable runtime specification. Compared with the WORX WG163, the appeal is the included battery and spool quantity, while the WORX provides a more clearly described support-wheel edging setup.
Pros:- Two 4.0Ah batteries are included.
- Eight replacement spools reduce the need to source line right away.
- Auto line feed supports continuous trimming without manual bumping.
- Listed 8,000 rpm speed is higher than the stated speeds of the WORX models here.
Cons:- The 12-inch cutting width is limited for covering large open lawns.
- Battery life is not specified in a useful runtime measure.
- The product data provides limited detail about battery compatibility and other operating features.
Best for: Buyers who want a cordless 2-in-1 trimmer with spare batteries and replacement spools included for regular small-yard upkeep.
Not ideal for: People who need a verified runtime estimate, a wide cutting path, or detailed information about the battery platform.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Speed:8,000 rpm
- Batteries:Two 4.0Ah batteries included
- Replacement spools:Eight included
- Functions:String trimming and edging
- Dimensions:17.32 inches long x 6.69 inches wide
Our verdict“Consider this model if the included batteries and replacement spools matter more to you than a documented runtime or a wider cutting path.”
BLACK+DECKER 13-Inch Electric Corded String Trimmer, 4 Amp Motor
If your work area is near an outlet, this corded BLACK+DECKER avoids battery charging and runtime limits altogether. Its 13-inch cutting width is slightly broader than the 12-inch cordless WORX WG163, so it can cover a little more ground per pass. The 4 Amp motor, automatic line feed, and conversion to edging keep the tool focused on basic lawn trimming without a battery kit to manage.
That simplicity depends on access to power: an extension cord restricts movement and can make a large or obstacle-filled yard awkward to cover. At 2.7 kg, the listed weight is also heavier than the 5.5-pound WORX WG163, though still described as lightweight. Unlike the cordless options, it has no battery to recharge, but it is a poor fit where cord reach is a recurring problem. I’d choose it for outlet-accessible small yards, not for unrestricted mobility.
Pros:- Corded power avoids battery runtime and recharging limits.
- 13-inch cutting width is broader than the 12-inch WORX WG163.
- Converts between trimming and edging.
- Automatic line feed supports continuous trimming.
Cons:- Requires an extension cord and access to an outlet.
- The cord restricts movement and can complicate work around obstacles.
- Listed weight of 2.7 kg is heavier than the 5.5-pound WORX WG163.
Best for: Homeowners with small, outlet-accessible yards who want steady corded operation for trimming and edging.
Not ideal for: People with large, divided, or obstacle-heavy yards where managing an extension cord will restrict movement.
- Power source:Corded electric
- Cutting width:13 inches
- Motor:4 Amp
- Weight:2.7 kg
- Functions:String trimming and edging
- Line feed:Automatic
- Dimensions:8.6 inches long x 6 inches wide
Our verdict“Choose this BLACK+DECKER when a cord can reach your lawn and you prefer uninterrupted operation over cordless freedom.”
Greenworks 40V 12 in Cordless String Trimmer with 2.0 Ah Battery and Charger
The Greenworks pairs a 12-inch dual-line head with a 40V battery platform, making it a sensible middle ground for routine trimming without a power cord. Its variable speed control lets me ease off around beds and fences, then pick up pace on open edges; auto feed also avoids the stop-and-bump routine. Compared with the lighter, corded BLACK+DECKER 14-Inch 2-in-1, this Greenworks gives me cordless freedom but a narrower cutting path and less direct suitability for extended heavy work. Its 2.0 Ah battery is better matched to smaller or medium maintenance jobs than a large property, and the listed 12-pound weight may feel substantial over a long session. I’d choose it for flexible everyday trimming, not for clearing dense growth all afternoon.
Pros:- Cordless 40V power avoids extension-cord limits around the yard
- Variable speed helps control trimming around delicate landscaping
- Auto-feed dual-line system reduces interruptions to adjust line
- Three-year warranty
Cons:- Included 2.0 Ah battery may not last through a large yard
- 12-pound listed weight can tire arms during prolonged trimming
- 12-inch cutting width covers less ground per pass than wider models
Best for: Homeowners with small-to-medium yards who want cordless freedom, variable speed, and routine edging without managing an extension cord
Not ideal for: Owners of large properties or people regularly cutting thick, overgrown weeds who need longer runtime or sustained heavy-duty performance
- Power source:Battery powered
- Cutting width:12 inches
- Speed:7,500 rpm
- Battery:One 2.0 Ah lithium-ion battery included
- Weight:12 pounds
- Line system:Dual line with auto feed
- Warranty:3 years
Our verdict“Choose the Greenworks for controlled cordless trimming across a modest yard, but look elsewhere for long sessions or a wider cutting swath.”
BLACK+DECKER Weed Wacker with Auto Feed, 14-Inch 2-in-1 String Trimmer Lawn Edger, 6.5-Amp Electric
The BLACK+DECKER’s strongest case is its 14-inch cutting path and quick conversion from trimmer to edger, backed by a 6.5-amp motor. The edging wheel helps guide straight borders, while auto-feed line removes the need to bump the head as line wears down. At 6.3 pounds, it is also much lighter than the 12-pound Greenworks 40V, a practical advantage when trimming around flower beds or along a long sidewalk. The tradeoff is the cord: reach depends on an outdoor extension cord and nearby outlets, so it is less convenient for scattered corners or a large, open yard. I’d favor it over cordless options when predictable access to power matters more than freedom of movement; skip it if cord management will slow the job.
Pros:- 14-inch cutting width covers more ground per pass than 12-inch options
- Converts between trimming and edging for lawn borders
- Edging wheel helps guide straighter lines along paths
- 6.3-pound weight is comparatively easy to handle
Cons:- Cord restricts reach and requires an outdoor extension cord
- Movement around trees and garden beds can be awkward with a cable
- Less suited to remote parts of a yard without convenient power access
Best for: Homeowners with a small-to-medium yard, an outdoor outlet, and frequent need to alternate between trimming and edging
Not ideal for: People with large or disconnected lawn areas, or anyone who wants to trim without managing an extension cord
- Power source:Corded electric
- Motor:6.5 amps
- Cutting width:14 inches
- Speed:8,000 rpm
- Weight:6.3 pounds
- Functions:String trimmer and lawn edger
- Warranty:2-year limited warranty
Our verdict“Pick this BLACK+DECKER for lightweight trimming and guided edging near an outlet, not for unrestricted movement around a spread-out yard.”
Milwaukee 2825-20ST 18V Cordless Brushless String Trimmer with Attachment Capability
The Milwaukee is the lineup’s most expandable choice: its attachment-capable design can serve buyers who want more than a dedicated string trimmer, with compatible tools such as an edger, hedge trimmer, and pole saw. A 16-inch cutting width also covers more ground per pass than the 12-inch Greenworks and compact cordless picks here. Its brushless motor and listed speed of up to 6,200 rpm support demanding trimming, while the balanced design is intended to help control the tool. That capability comes with real costs: at 12.7 pounds, it is heavy for extended handheld use, and the battery is sold separately. Unlike the ready-to-use kits in this roundup, it makes the most sense for someone already invested in the compatible battery platform or planning to build out a tool system.
Pros:- Attachment capability supports compatible yard-care tools beyond trimming
- 16-inch cutting width covers more area per pass than 12-inch models
- Brushless motor design is suited to demanding trimming tasks
- Balanced design supports controlled handling
Cons:- 12.7-pound weight can be tiring during prolonged use
- Battery and charger are not included
- 18V platform ties the purchase to compatible Milwaukee batteries
Best for: Landscapers and homeowners who already own compatible Milwaukee batteries and want one powerhead for multiple yard attachments
Not ideal for: First-time buyers seeking a complete, lightweight trimmer kit or anyone who only needs occasional light edging
- Power source:Battery powered
- Voltage:18V
- Motor:Brushless
- Cutting width:16 inches
- Speed:Up to 6,200 rpm
- Weight:12.7 pounds
- Attachment capability:Compatible with attachments including edger, hedge trimmer, and pole saw
Our verdict“Choose the Milwaukee if attachment flexibility and a wide cutting path matter more than low weight or an included battery.”
Electric Weed Wacker 21V Cordless Battery-Powered String Trimmer with Dual Batteries
At 5.3 pounds, this 21V trimmer is the easiest option in this group to maneuver around borders and garden beds. Its 12-inch head, 9,000 rpm listed speed, and switchable trimming-and-edging setup suit quick touch-ups rather than clearing a neglected lot. Two included batteries can reduce downtime if one is charging, but the listed runtime is only 12 minutes; the description also gives a longer 15–20-minute estimate, so I would plan around short sessions rather than count on uninterrupted work. Compared with the heavier Greenworks 40V, this model is easier to carry but offers less reassurance for lengthy yard maintenance. I’d consider it for light-duty upkeep where low weight is the priority, and pass if battery time or performance in thick growth is the deciding factor.
Pros:- 5.3-pound weight makes it easy to maneuver around garden edges
- Two batteries provide a spare for swapping between short sessions
- Converts between trimming and edging
- 9,000 rpm listed speed suits quick light-duty maintenance
Cons:- Listed battery life is only 12 minutes, with the description offering a different estimate
- 12-inch cutting width is less suited to covering broad areas quickly
- Short runtime limits longer or more demanding trimming sessions
Best for: People with a small yard or garden who need a light trimmer for brief edging and routine touch-ups
Not ideal for: Owners of larger lawns or anyone tackling dense weeds who needs dependable long runtime or sustained cutting power
- Power source:Battery powered
- Voltage:21V
- Cutting width:12 inches
- Speed:9,000 rpm
- Batteries:Two included
- Listed battery life:12 minutes
- Weight:5.3 pounds
- Functions:String trimmer and edger
Our verdict“Pick this model for lightweight, short yard jobs, but choose a longer-running trimmer for larger lawns or dense growth.”
20V Cordless String Trimmer with Dual 2.0Ah Batteries and Charger
This 20V model is aimed at homeowners who want a compact cordless tool for small lawns and tight spaces. The foldable design and adjustable head and handle make storage and positioning easier, while auto line feed reduces pauses to manage line. Two included 2.0Ah batteries are listed for up to 30 minutes of runtime, giving it a clearer small-yard use case than the 21V trimmer’s shorter listed battery life. Its 12-inch cutting width still limits how quickly it can cover open ground, and the product description cautions against thick or dense grass. Battery cooling time between uses may also interrupt a longer session. I’d choose it for routine light trimming and convenient storage, rather than as a substitute for a heavier-duty machine like the attachment-capable Milwaukee.
Pros:- Foldable design makes storage more convenient
- Two included 2.0Ah batteries support up to 30 minutes of runtime
- Adjustable head and handle help reach different trimming positions
- Auto line feed avoids manual bumping to advance line
Cons:- 12-inch cutting width is modest for broad areas
- Not suited to very thick or dense grass
- Battery cooling time may interrupt back-to-back use
Best for: Homeowners with a small yard, limited storage space, and mostly light grass trimming around paths and beds
Not ideal for: People with large properties or dense, overgrown grass who need longer continuous operation and heavier cutting capability
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Speed:9,500 rpm
- Batteries:Two 2.0Ah lithium-ion batteries included
- Listed runtime:Up to 30 minutes
- Design:Foldable, with adjustable head and handle
- Line feed:Automatic
Our verdict“Choose this trimmer for compact storage and light-duty work in a small yard, not for dense growth or long uninterrupted sessions.”
Husqvarna WeedEater 320iL Cordless String Trimmer, 16-Inch, with 4 Ah Battery & Charger
The 16-inch cutting width gives the Husqvarna 320iL a broader pass than the 12-inch EWORK, which can mean fewer passes along long fence lines and lawn edges. Its power boost mode adds extra help when weeds thicken, while the dual-direction head supports flexible trimming and edging. At 7 pounds, it is also lighter than the EWORK’s listed 7.8 pounds, a useful difference during longer sessions. The included 40V battery and charger make it ready for cordless work without a separate battery purchase. The tradeoff is runtime: the supplied 4 Ah battery may not cover extensive jobs, and a corded option such as the BLACK+DECKER BESTE620 avoids battery limits altogether. Assembly is required, too, so this is a better fit for routine yard work than a no-setup solution.
Pros:- 16-inch cutting width covers more ground per pass than the 12-inch EWORK
- Power boost mode provides extra capability for heavier weeds
- Dual-direction head supports flexible trimming and edging
- Includes a 40V, 4 Ah battery and charger
Cons:- Included battery may not last through large yard jobs
- Requires some assembly before use
- Battery appearance may vary from product images
Best for: Homeowners who want a wide cutting path and cordless freedom for regular trimming across a medium-sized yard.
Not ideal for: People with large properties who need long uninterrupted runtime, or buyers who prefer a corded tool that does not depend on battery charge.
- Power source:Battery powered
- Cutting width:16 inches
- Battery:One 40V lithium-ion battery included; 4 Ah
- Weight:7 pounds
- Dimensions:68 x 13 inches
- Head:Dual-direction
- Additional feature:Power boost mode
- Model:970480104
Our verdict“Choose the Husqvarna for a wider cordless cutting path and boost mode, but look elsewhere if your yard needs extended runtime without recharging.”
EWORK 2-in-1 Cordless Weed Wacker & Edger, 20V, 12-inch Electric Weed Eater
The EWORK’s practical distinction is its two included 20V batteries and six spool lines, a useful bundle for anyone who wants a spare charged pack and replacement line ready. Its 12-inch head is narrower than the Husqvarna 320iL’s 16-inch swath, so it will take more passes across open ground, but that smaller cutting width suits detail work around beds and walkways. A 9000 RPM motor, automatic line feed, and switchable trimmer-edger setup cover routine lawn maintenance without bumping the head to advance line. The adjustable shaft helps fit different users, though changing angles and heights takes manual adjustment. The product description cites thick weeds, but its listed power may not satisfy buyers tackling dense growth; the Husqvarna’s boost mode is a more explicit choice for that job.
Pros:- Includes two 20V batteries, a charger, and six spool lines
- Converts between trimming and edging
- Automatic line feed avoids bumping the head
- Adjustable shaft supports different users and working positions
Cons:- 12-inch cutting width covers less ground per pass than the Husqvarna 320iL
- May lack power for very thick weeds
- Angle and height changes require manual adjustment
Best for: Beginners and households wanting a cordless trimmer-edger with a spare battery and extra line for small to medium routine jobs.
Not ideal for: Buyers regularly cutting dense, established weeds or covering broad lawns where a wider cutting path would reduce passes.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Motor speed:9000 RPM
- Batteries:Two included
- Weight:7.8 pounds
- Dimensions:41 x 9 inches
- Additional details:Automatic line feed; trimmer and edger modes
Our verdict“Pick the EWORK for its spare battery and easy line feeding on routine yard jobs, not for heavy growth or wide-area cutting.”
13-Inch Electric Weed Wacker, 4-in-1 Cordless String Trimmer, Lawn Edger, Mower & Brush Cutter with Dual 21V 6.0Ah Batteries & Charger
Rather than focusing only on string trimming, this 13-inch cordless model is presented as a four-function yard tool: trimmer, edger, mini mower, and brush cutter. That versatility may reduce the need to switch between separate tools for smaller garden jobs. Its stated 15000 RPM brushless motor and two included 21V batteries give it a different pitch from the EWORK, which emphasizes automatic line feed and comes with spare spool line. The wider 13-inch path also exceeds the EWORK’s 12 inches, though it remains narrower than the Husqvarna 320iL. The tradeoff is that the supplied information does not specify weight or runtime, so buyers cannot readily judge carrying comfort or how much ground the batteries cover. First-time assembly may take effort, and a specialized trimmer may be simpler for buyers who only need line trimming.
Pros:- Designed for trimming, edging, mini mowing, and brush cutting
- Brushless motor is listed at 15000 RPM
- Includes two 21V batteries and a charger
- 13-inch cutting width is broader than the EWORK’s 12-inch path
Cons:- Assembly may take effort for first-time users
- Runtime and item weight are not specified in the supplied product data
- Four-function setup may be more tool than needed for simple line trimming
Best for: Gardeners who want one cordless tool for several kinds of small-yard maintenance and are comfortable assembling attachments or components.
Not ideal for: Buyers seeking a straightforward dedicated trimmer, or those who need clearly specified runtime and weight before choosing a tool for extended sessions.
- Power source:Battery powered
- Cutting width:13 inches
- Motor:Brushless
- Motor speed:15000 RPM
- Batteries:Two 21V, 6.0Ah batteries included
- Functions:String trimmer, lawn edger, mini mower, brush cutter
- Dimensions:33 x 8 inches
- Color:Green
Our verdict“Choose this model if you value several yard-care functions in one cordless tool, but favor a dedicated trimmer when simplicity and clearly stated runtime matter more.”
BLACK+DECKER 14-inch Electric String Trimmer (BESTE620)
The BESTE620 is the clearest choice here for buyers who would rather plug in than manage battery charge. Its corded power avoids the runtime limits attached to the Husqvarna 320iL and the battery-powered EWORK, while the 14-inch cutting width sits between their 16- and 12-inch paths. At just 5.3 pounds, it is lighter than either of those cordless options, which can make repeated edging and trimming less tiring. EasyFeed advances line without bumping, and the wheeled-edger conversion gives it a useful second role. The main compromise is mobility: the cord restricts where you can work and calls for attention around obstacles. Its 6.5-amp motor may also struggle with very thick weeds, so the Husqvarna’s boost mode is a better match for tougher growth.
Pros:- Corded operation avoids battery runtime limits
- Lightweight 5.3-pound design
- EasyFeed advances line without bumping
- Converts from trimmer to wheeled edger with adjustable handle and height
Cons:- Power cord restricts working range and can snag around obstacles
- 6.5-amp motor may struggle with very thick weeds
- 14-inch cutting width is narrower than the Husqvarna 320iL
Best for: Homeowners with an accessible outdoor outlet who want a lightweight trimmer-edger for regular lawn edges and lighter weeds.
Not ideal for: People trimming far from an outlet, working around many obstacles, or regularly cutting dense weeds that may challenge its motor.
- Power source:Corded electric
- Motor:6.5 amp
- Cutting width:14 inches
- Weight:5.3 pounds
- Dimensions:9 x 5 inches
- Line advancement:EasyFeed
- Configuration:Trimmer and wheeled edger
- Warranty:2-year limited warranty
Our verdict“Choose the BESTE620 for lightweight trimming near an outlet without battery interruptions, but skip it if cord-free mobility is a priority.”
Weed Wacker Eater Electric String Trimmer Battery Powered Lawn Trimmer
At 5.3 pounds, this cordless trimmer is the lightest listed option in this batch, making it appealing for quick touch-ups where a heavier tool would feel like overkill. It switches between trimming and edging and has a 12-inch cutting width, so it is aimed more at lawn borders and light growth than the Husqvarna 320iL’s broader 16-inch swath. Two included 2.0Ah batteries offer a spare, but the stated 15-minute battery life sets a firm limit on each session. That makes this a more focused small-yard pick than the EWORK, whose supplied details do not give a specific runtime. Quiet operation and tool-free assembly add convenience, but buyers with longer fence lines or larger lawns should choose a trimmer with more documented endurance.
Pros:- 5.3-pound weight makes it easy to carry and maneuver
- Includes two 2.0Ah batteries
- Switches between trimming and edging
- Quiet operation and tool-free assembly
Cons:- Stated battery life is about 15 minutes
- 12-inch cutting width is narrower than the Husqvarna 320iL’s 16 inches
- Best suited to light trimming rather than large or demanding jobs
Best for: People with small yards who want a light cordless tool for short trimming and edging sessions.
Not ideal for: Owners of larger lawns or anyone needing to trim for longer than the stated 15-minute battery life without stopping to recharge or swap packs.
- Power source:Battery powered

Our verdict“Pick this trimmer for brief, light-duty work in a small yard; its short stated runtime makes it a poor fit for extended sessions.”
How We Picked
I compared these 15 electric grass trimmers on buyer-facing factors: cutting width, power source, battery details supplied with the tool, handling-oriented features, edging or other modes, and the likely upkeep burden. I gave weight to features that change everyday yard work, such as avoiding a cord, having a battery and charger included, or covering more ground per pass. I also treated versatile designs cautiously: an extra mode is useful only if it suits a buyer’s actual lawn tasks.
The ranking reflects fit across common needs rather than a claim that one trimmer is best for every yard. The Husqvarna takes the lead for its wider 16-inch cut and included 4 Ah battery; BLACK+DECKER and WORX options rank well for approachable trimming and edging combinations, while the corded BLACK+DECKER is a practical choice when continuous power matters more than mobility. The Milwaukee earns a distinct place for attachment capability, but that feature makes most sense for buyers already invested in compatible tools. Models with limited specification detail or broad multi-function claims are better treated as niche choices until their included accessories and battery arrangements are confirmed.

Factors to Consider When Choosing Best Electric Grass Trimmers
Before choosing, I would match the trimmer to the shape of the yard and the work it needs to do, rather than comparing headline voltage alone. A narrow lawn with many borders creates different demands from a long fence line or a patch of rough growth. These factors help separate genuinely useful convenience from features that add bulk or upkeep.
Choose Corded or Cordless Around Your Work Area
A corded trimmer can keep running without battery swaps, which helps when the work area is close to an outlet and the trimming session is long. Its limit is reach: the cord can snag on shrubs, cross walkways, or restrict movement around a large yard. Cordless models remove that tether, but runtime depends on battery capacity, cutting conditions, and how often the tool is run at full power. Do not treat voltage by itself as a runtime estimate; check the battery’s amp-hour rating and whether the listing includes a pack and charger. If you already own compatible batteries, platform compatibility may matter more than the included bundle. For a yard with distant edges and no convenient outlet, cordless freedom can save more hassle than continuous corded operation.
Match Cutting Width to Yard Layout
A wider cutting path reduces the number of passes across open ground, but it can be harder to maneuver precisely around narrow beds, posts, and tree trunks. Compact 12-inch models can feel better suited to careful edging and confined spaces, while 14- or 16-inch heads may help with longer borders and broader patches. The stated width is not a promise of faster work if the user has to move cautiously around obstacles. Think about the balance of open lawn and detailed trimming, not just total yard size. Buyers with many delicate plantings may benefit more from control than extra reach. Those maintaining long, uncomplicated edges may value fewer passes instead.
Treat Battery Capacity and Spare Packs as Separate Questions
A battery included in the box makes a cordless trimmer ready to use, but it does not tell you how long it will run. Higher amp-hour capacity generally means more stored energy, though actual runtime varies with grass thickness, line condition, and tool load. A dual-battery bundle can be handy if one pack can charge while the other is in use, but confirm whether both batteries are included and whether the charger supports the needed pace. Some listings give less detail than others, so verify the exact pack capacity and included accessories before deciding. If the trimmer is part of a larger battery platform, compatible packs can reduce the need to keep buying a separate power system. Avoid paying for spare capacity you are unlikely to use on short sessions.
Decide Whether Edging and Extra Modes Earn Their Keep
A rotating head or dedicated edging mode can help create a cleaner border without switching tools, particularly along paths and driveways. A mini-mower or brush-cutter label may sound useful, but the actual job each mode can handle depends on the design and included attachments. More modes can also bring added adjustment steps, weight, and parts to maintain. Attachment-capable tools make more sense for buyers who plan to expand a compatible system than for someone who only trims grass. Before choosing a multi-function model, check what is included rather than assuming every pictured accessory comes in the box. If trimming and basic edging cover your needs, a simpler tool may be easier to store and operate.
Account for Line Feeding and Routine Upkeep
String trimmers use up cutting line, so spool replacement and feed design affect how often work pauses. Auto-feed systems can reduce manual line adjustments, but they do not prevent line jams or eliminate the need to replace the spool. Bump-feed designs give the operator more control over line release but require a deliberate technique. Look up the replacement spool or line type before buying, especially when a proprietary format could make restocking less convenient. Keep the cutting head clear of wrapped grass and check the guard and line before each session. A trimmer that is easy to reload can be a better long-term fit than one with extra modes you rarely use.
Prioritize Handling and Safety for Your Yard’s Conditions
Tool weight, balance, shaft adjustment, and grip shape influence comfort more than a single advertised power figure. A wider head or larger battery can increase reach or runtime while also making the tool feel more tiring during extended edging. For slopes, tight corners, or frequent overhead trimming, control and manageable weight deserve extra attention. Use eye protection and suitable footwear, and keep people and pets away from the cutting area because line can throw debris. Check that the guard is present and correctly fitted rather than removing it to gain reach. If possible, compare the tool’s assembled weight with battery installed, since package weight can understate what you will hold.
Frequently Asked Questions
Is a corded electric trimmer a better choice than a cordless one for a small yard?
It can be, especially when the whole lawn is within comfortable extension-cord reach and you prefer not to manage batteries. A corded model avoids pauses for charging and battery swaps, but the cord needs attention around corners, plants, and walkways. For a small yard with many obstacles, cordless freedom may be worth more than unlimited runtime. Check the outlet location and the route you would need to trim before choosing. If you already own a compatible battery system, that can make a cordless option more convenient.
Does a wider cutting head always make a trimmer faster?
No: a wider head covers more ground per pass, but it can be less precise around beds, posts, and narrow borders. Its advantage is clearest on open stretches where the operator can move steadily. In a cramped garden, a narrower head may reduce repositioning and accidental contact with plants. Consider how much of your work is open trimming versus detailed edging. Cutting width is most useful when it matches the shape of the yard.
How should I compare cordless trimmer batteries when listings show different voltage and capacity?
Use voltage as one clue about the tool’s electrical platform, not as a direct measure of runtime. Amp-hour capacity gives a better indication of stored energy, but actual run time still changes with grass density, line length, and how hard the trimmer is working. Check the exact battery and charger included, and verify whether a listing with two batteries supplies two usable packs. If you own batteries from the same platform, compatibility can affect the value of the package. For long sessions, the ability to swap in a charged spare may matter more than a small difference in voltage.
Are 2-in-1 or 3-in-1 trimmers worth choosing over a basic string trimmer?
They are worthwhile when their extra functions match tasks you already do, such as edging a driveway or cutting small areas of lawn with a mini-mower mode. A simple trimmer can be lighter and less complicated if you only need to tidy grass along fences. Extra modes may require adjustments or accessories, so confirm what comes with the tool and how each function is used. Attachment capability has more value if you plan to build around the same compatible tool system. Do not choose on the number of modes alone; choose on the jobs those modes can realistically replace.
What should I check before buying an electric trimmer for heavy or overgrown grass?
Look beyond the word “electric” and check the tool’s intended cutting conditions, cutting width, battery capacity, and whether it accepts suitable attachments. Grass that is thick, tall, or woody can drain a battery faster and put more strain on a line-trimmer head than routine lawn edges do. A wider cutting path may help on open areas, but it does not automatically make a light-duty trimmer suited to brush. Confirm whether a brush-cutter attachment is included or sold separately, and review the maker’s guidance for compatible cutting heads. If most of your work is heavy growth, choose for that task rather than expecting a basic string trimmer to handle every condition.
Conclusion
For the broadest mix of reach and cordless yard coverage, I would choose the Husqvarna WeedEater 320iL as the best overall pick. Buyers seeking a straightforward value-oriented trimmer and edger should compare the BLACK+DECKER 20V 2-in-1 and WORX WG163, checking battery details and included accessories before deciding. The Milwaukee 2825-20ST is my best premium-style fit for buyers who value brushless operation and attachment capability, especially if they already use compatible tools. For beginners, a simple 2-in-1 such as the BLACK+DECKER or WORX option keeps basic trimming and edging in one tool without making a multi-mode design the main attraction. Choose the BLACK+DECKER corded 4-amp trimmer if uninterrupted runtime matters more than mobility; choose the WORX WG170 if its mini-mower function fits your lawn. The right pick is the one whose power source, reach, and functions match the jobs you actually do.
