The best electric grass trimmers balance cutting power, manageable weight, and runtime or cord reach for the yard you actually maintain. My best overall pick is the Husqvarna 320iL, which pairs a 4 Ah battery kit with a more substantial cordless setup; the BLACK+DECKER BESTA510 is a practical corded choice, while the WORX WG163 suits buyers who want a compact trimmer that also edges. The main tradeoff is straightforward: corded models avoid battery limits but tether you to an outlet, while cordless models offer freedom but require planning for runtime and charging. Cutting width, line or blade systems, and attachment compatibility also affect how well a trimmer fits your yard. Read on for my full comparison, buying advice, and picks by buyer type.

Key Takeaways
- The Husqvarna 320iL is the strongest all-round cordless fit in this lineup: its included 4 Ah battery makes it a more ready-to-use choice than tool-only options such as the Milwaukee 2825-20ST.
- Corded models remain compelling for small yards near an outlet: the BLACK+DECKER BESTA510 and BESTE620 remove battery-runtime planning, but cord management limits reach and freedom.
- Battery platform matters as much as the trimmer: the Makita, Milwaukee, Greenworks, and EGO options make most sense when their batteries can serve other compatible tools.
- Combination features favor convenience, not necessarily cutting performance: edger and multi-function designs like the WORX WG163 and WeGofly 4-in-1 can reduce tool switching but add complexity.
- Wider cutting paths are not an automatic upgrade: a 14-inch path on the BLACK+DECKER corded picks covers ground quickly, while a narrower or lighter setup may be easier around beds and tight borders.

More Details on Our Top Picks
BLACK+DECKER BESTA510 14-Inch 6.5-Amp Corded Electric String Trimmer and Lawn Edger
The BESTA510 is my strongest corded pick for buyers who want one tool for trimming and crisp lawn edges. Its 14-inch cutting width covers more ground per pass than the BEST935’s 13-inch path, while the wheeled edger conversion makes straight borders easier to guide. The automatic feed spool advances line without bumping, a useful convenience for routine yard work. At 6.3 pounds, it is lighter than the listed Greenworks 40V trimmer, though the cord limits how far you can roam and requires an outlet and extension cord. I’d choose it over the BEST935 when the wider cut and more powerful 6.5-amp motor matter; choose the BEST935 instead if low listed weight is your priority. Neither is a good fit for cord-free trimming.
Pros:- Converts to a wheeled edger for guided lawn borders
- 14-inch cutting width is wider than the BEST935’s 13-inch path
- Automatic line feed advances line without bumping
- Adjustable handle and cord retention support controlled operation
Cons:- Requires an extension cord and limits movement to its reach
- No battery option for work away from an outlet
Best for: Homeowners with a nearby outdoor outlet who want a wider cutting path and guided edging for lawns, sidewalks, and beds.
Not ideal for: People trimming far from an outlet or moving around a large, obstacle-filled yard where a cord will restrict reach.
- Power source:Corded electric
- Motor:6.5 amp
- Cutting width:14 inches
- Speed:8,000 rpm
- Weight:6.3 pounds
- Line feed:Automatic feed spool
- Included components:String trimmer, AF-100 spool, auxiliary handle, and guard
- Warranty:2-year limited warranty; 30-day money-back guarantee
Our verdict“Choose the BESTA510 if you want a capable, wider-cut corded trimmer that also guides edging; skip it if cord-free reach matters.”
Makita XRU23Z 18V LXT Brushless Cordless 13-Inch String Trimmer
For buyers already invested in Makita’s 18V LXT platform, the XRU23Z offers cordless control without adding a gas engine’s upkeep. Its brushless motor, variable-speed trigger, and high/low setting let you moderate output for careful edging or raise it for tougher patches. With a compatible 4.0Ah battery, the listing gives runtime of up to one hour, a longer stated working window than the 15–20 minutes supplied by the 21V cordless trimmer. That comparison comes with an important caveat: this is tool only, so battery and charger costs and availability are part of the decision. Its 13-inch cut is also narrower than the BESTA510’s 14-inch swath. I’d pick Makita for speed control and shared-battery convenience, not for buyers starting from scratch.
Pros:- Brushless motor reaches up to 6,000 RPM
- Variable trigger and high/low setting give control over cutting speed
- Up to one hour of stated runtime with a compatible 4.0Ah battery
- XPT protection is designed to resist dust and water exposure
Cons:- Battery and charger are sold separately
- The 13-inch cutting width is narrower than the BESTA510’s 14 inches
Best for: Makita 18V LXT owners who want a cordless trimmer with adjustable speed for routine trimming and precise edging.
Not ideal for: First-time cordless-tool buyers who need a battery and charger included, or shoppers who want a wider cutting path.
- Power source:18V LXT lithium-ion battery
- Motor:Brushless
- Cutting width:13 inches
- Maximum speed:6,000 RPM
- Runtime:Up to 1 hour with an 18V LXT 4.0Ah battery
- Speed control:Variable-speed trigger and high/low button
- Line loading:Rapid-load bump-and-feed head
- Included:Tool only; battery and charger sold separately
Our verdict“Choose the XRU23Z if you already own Makita 18V LXT batteries and value adjustable cordless performance over an included battery kit.”
21V Cordless Weed Whacker Battery Powered Lawn Trimmer 12-Inch
This 21V trimmer is the easy-to-handle pick for beginners with a small yard and short trimming sessions. At 5.3 pounds, it is lighter than the BESTA510, and its quick, tool-free assembly reduces setup hassle. Two included 2.0Ah batteries give you a spare to swap in, although the stated runtime is only 15–20 minutes per charge; having two batteries does not make either one last longer. Its 12-inch cutting path is narrower than the BESTA510’s 14 inches, so larger lawns may take more passes. The listed 9,000 RPM head suits light grass and routine edging, but the product data warns it may struggle in thick brush. I’d favor it over the Makita XRU23Z for an included-battery starter package, while Makita is better suited to buyers seeking a stated longer runtime with a compatible battery.
Pros:- Light 5.3-pound weight can make short jobs easier to handle
- Two 2.0Ah batteries are included for swapping between charges
- Tool-free assembly keeps setup straightforward
- 12-inch cutting width and 9,000 RPM head suit routine light trimming
Cons:- Runtime is limited to a stated 15–20 minutes per battery
- May be underpowered for dense or thick brush
- Narrower cutting path than the BESTA510 means more passes
Best for: New trimmer owners with a small lawn who prioritize low weight, simple assembly, and a second battery for short jobs.
Not ideal for: People with large properties, dense weeds, or long trimming sessions who need longer runtime or more cutting capacity.
- Power source:Battery powered
- Voltage:21V
- Cutting width:12 inches
- Speed:9,000 rpm
- Batteries:Two included, 2.0Ah each
- Battery runtime:15–20 minutes per charge
- Weight:5.3 pounds
- Dimensions:47.24 inches long × 11.81 inches wide
Our verdict“Choose this kit for light-duty trimming in a small yard when ease of handling matters more than long runtime or heavy-weed capacity.”
Greenworks 40V 12-Inch Cordless String Trimmer with 2.0 Ah Battery and Charger
The Greenworks 40V makes sense for buyers who want a battery and charger in the box rather than piecing together a tool-only setup like the Makita XRU23Z. Its automatic line feed removes the need to bump the head to advance line, and the variable-speed trigger lets you tailor output for lighter trimming. The 12-inch cutting width is suited to routine lawn edges and light weeds, but it covers less ground per pass than the BESTA510’s 14 inches. Greenworks lists a 2.0Ah battery and charger as included, along with a three-year limited tool and battery warranty. The main compromise is scope: this is described for grass and light weeds, not dense growth, and larger yards may demand repeated passes. Its listed 12-pound weight is also higher than the BESTA510’s 6.3 pounds.
Pros:- 40V, 2.0Ah battery and charger are included
- Automatic line feed advances line during work
- Variable-speed trigger supports lighter trimming control
- Three-year limited tool and battery warranty is listed
Cons:- 12-inch cutting width may require more passes across larger areas
- Intended for grass and light weeds rather than dense growth
- Listed weight of 12 pounds is heavier than the BESTA510
Best for: Homeowners who want a cordless trimmer kit with battery, charger, automatic line feed, and a stated warranty for regular light-duty yard care.
Not ideal for: Buyers tackling dense weeds or large areas who want a wider swath and a lighter listed tool.
- Model:2101602
- Power source:40V battery powered
- Battery:2.0Ah lithium-ion, one included
- Included:Battery and charger
- Cutting width:12 inches
- Line:0.065-inch dual line
- Line feed:Automatic
- Speed and weight:7,500 rpm; 12 pounds
- Warranty:3-year limited tool and battery warranty
Our verdict“Choose the Greenworks 40V if you want a complete cordless kit for routine light trimming and edging, rather than a wider or heavier-duty cutter.”
BLACK+DECKER BEST935 13-Inch Corded Electric String Trimmer and Edger
The BEST935 is the corded option I’d shortlist for buyers who value low listed weight and quick edging more than extra motor power. It has a 13-inch cutting swath, automatic line feed, and a quick conversion to an edger, covering the core jobs of the BESTA510. The difference is that the BESTA510 has a 6.5-amp motor and 14-inch cut, while this model uses a 4-amp motor and a slightly narrower path. The BEST935’s listed 2.7 kg weight may appeal to people who want a lighter-feeling corded tool, but its cord still restricts reach, just as it does with the BESTA510. I’d choose this model for straightforward trimming and edging near an outlet; skip it if you need cordless freedom or want the wider swath of its BLACK+DECKER sibling.
Pros:- Quickly converts from string trimmer to edger
- Automatic line feed advances line without bumping
- 13-inch cutting swath suits routine lawn trimming
- Auxiliary handle supports two-handed control
Cons:- Corded operation limits reach and freedom of movement
- 4-amp motor and 13-inch path offer less capacity than the BESTA510
Best for: Homeowners with a small or medium lawn near an outdoor outlet who want a lighter corded trimmer that converts to an edger.
Not ideal for: People who need cordless mobility, a wider cutting path, or more motor power for demanding growth.
- Model:BEST935
- Power source:Corded electric
- Motor:4 amp
- Cutting width:13 inches
- Weight:2.7 kg
- Line feed:Automatic
- Included components:String trimmer and AF-100 spool
- Warranty:2-year limited warranty
Our verdict“Pick the BEST935 for simple corded trimming and edging when its lighter listed weight matters more than the BESTA510’s wider cut and stronger motor.”
Greenworks 24V 13″ String Trimmer, 10 Blades, 4.0 Ah Battery
The Greenworks 24V suits routine edging and grass trimming when low carry weight matters more than a wide cutting path. Its 13-inch swath is narrower than the Husqvarna 320iL’s 16 inches, so it may take longer across open ground, but the 5.51-pound listed tool weight should be easier to handle around beds and fences. A brushless motor and auto-feed line reduce upkeep during ordinary trimming, while its 2-in-1 design also handles edging. The package description lists a 4.0 Ah battery, yet the product information also warns that the battery may be sold separately, so I would verify the kit contents before buying. The USB-C charger adds flexibility, but the ten plastic blades may wear quickly and are not a substitute for string on every task.
Pros:- Brushless motor is designed for efficient power and longer service life.
- 13-inch cutting path and 2-in-1 trimmer-edger design suit routine lawn edges.
- Auto-feed line avoids manual bumping or frequent feed adjustments.
- 65W USB-C charger can also charge compatible personal devices.
Cons:- Battery inclusion is unclear in the product information despite the title listing a 4.0 Ah battery.
- Included plastic blades may wear quickly and need frequent replacement.
- Its 13-inch cutting width covers less ground per pass than the Husqvarna 320iL.
Best for: Homeowners with small or medium yards who want a relatively light brushless trimmer for regular edging and trimming.
Not ideal for: Buyers who need a verified complete battery kit, frequent heavy-duty cutting, or a wider swath for large open lawns.
- Power source:Battery powered
- Voltage:24V
- Cutting width:13 inches
- Line diameter:0.080 inch
- Battery capacity:4.0 Ah
- Tool weight without battery:5.51 lbs
- Charger:65W USB-C
- Warranty:3 years
Our verdict“Choose the Greenworks if you value a light brushless tool for routine yard trimming, but confirm the battery is included and expect blade upkeep.”
WeGofly 13-Inch Cordless 4-in-1 String Trimmer
The WeGofly 4-in-1 is the most adaptable option here for buyers who want one tool to cover several light yard jobs: trimming, edging, mini mowing, and brush cutting. Its adjustable components and 13-inch cutting width give it more flexibility than the simpler WORX WG163, which focuses on trimming and edging. The package description lists two 21V 6.0 Ah batteries, a charger, replacement blades, line, and a storage bag, a broad accessory set for users who do not already own compatible gear. But the battery details conflict: the title says two are included while the specifications say one is required, and no runtime is provided. I would treat its range of functions as a convenience rather than proof of heavy-duty capability; buyers needing predictable coverage may prefer a more clearly specified kit.
Pros:- Combines string trimming, edging, mini mowing, and brush-cutting functions.
- Adjustable cutting head and telescopic pole support different positions and users.
- Package description lists two 21V 6.0 Ah batteries and a charger.
- Replacement blades, trimmer lines, and storage bag are listed as included.
Cons:- Battery quantity is inconsistent between the title and specifications.
- No runtime information is provided, making coverage per charge hard to judge.
- Four functions add flexibility but do not establish suitability for sustained heavy-duty cutting.
Best for: Yard owners seeking a flexible cordless tool for several light-duty jobs and who are willing to confirm the battery package before purchase.
Not ideal for: Buyers who need clear runtime expectations, verified battery quantities, or a straightforward trimmer for demanding brush work.
- Power source:Battery powered
- Functions:String trimmer, lawn edger, mini mower, brush cutter
- Cutting width:13 inches
- Motor speed:15,000 RPM
- Battery:Two 21V 6.0 Ah batteries listed in description; quantity is inconsistent in source
- Weight:5.2 lbs
- Warranty:3 years for main unit; 2 years for batteries
Our verdict“Pick the WeGofly for varied light yard work if you confirm the battery contents first; choose a simpler, better-documented kit for predictable trimming needs.”
Husqvarna 320iL Cordless String Trimmer with 4 Ah Battery and Charger
The Husqvarna 320iL earns its place for buyers who want to clear more grass with each pass: its 16-inch cutting width is broader than the 13-inch paths on the Greenworks 24V and BLACK+DECKER LST136. That difference can reduce back-and-forth work on open lawn edges, while the brushless motor and power-boost mode offer extra output when ordinary trimming is not enough. Its dual-direction head is useful when clipping direction matters, and Rapid Replace loading is intended to simplify string changes. The tradeoff is weight: at 7 pounds, it is heavier than the 5.5-pound WORX WG163, which may be more comfortable for short, frequent touch-ups. The 40V 4 Ah battery and charger are included, but cordless runtime still depends on charge, and the listed dimensions are incomplete.
Pros:- 16-inch cutting width covers more ground per pass than the 13-inch options in this group.
- Brushless motor and power-boost mode provide a higher-output option for tougher patches.
- Dual-direction head helps manage where clippings are thrown.
- Includes a 40V 4 Ah battery and charger.
Cons:- At 7 pounds, it is heavier than the WORX WG163 and may tire users during extended work.
- Runtime depends on battery charge, and no runtime figure is supplied.
- Listed dimensions omit height.
Best for: Owners of medium or larger yards who want a wider cutting path and an included battery-and-charger kit.
Not ideal for: People prioritizing a light tool for brief edging sessions or anyone who needs published runtime figures before choosing a cordless trimmer.
- Power source:Battery powered
- Cutting width:16 inches
- Battery:40V lithium-ion, 4 Ah
- Motor:Brushless
- Weight:7 pounds
- Dimensions:68 × 13 inches; height not specified
- Included:Battery and charger
- Model:970480104
Our verdict“Choose the Husqvarna for a wider cutting path and included 40V kit, but favor the lighter WORX WG163 for short, frequent trimming sessions.”
BLACK+DECKER LST136 40V MAX Cordless String Trimmer and Edger, 13-Inch, with Battery and Charger
The BLACK+DECKER LST136 is a practical choice for homeowners who want to adjust power and runtime rather than use one fixed setting. Its 40V MAX system, included 2.0 Ah battery, and fast charger make it a more clearly specified ready-to-use kit than the Greenworks 24V, whose battery listing is ambiguous. The automatic feed spool also avoids bumping the head, and the tool converts from trimmer to edger for lawn borders. Its 13-inch cutting path is narrower than the Husqvarna 320iL’s 16 inches, so it is better suited to modest lawns and detail work than rapid coverage of broad areas. No runtime figure is given, and the source lists conflicting warranty lengths, so I would not choose it on assumptions about charge duration or coverage terms.
Pros:- Adjustable power and runtime settings let users trade cutting intensity for battery use.
- Automatic Feed Spool feeds line without bumping.
- Converts between string trimmer and lawn edger.
- Includes a 40V MAX 2.0 Ah battery and fast charger.
Cons:- No runtime figure is provided.
- The source gives conflicting warranty terms.
- Its 13-inch cutting width is narrower than the Husqvarna 320iL’s 16-inch path.
Best for: Homeowners with small or medium lawns who want a cordless trimmer-edger with adjustable power and a listed battery and charger.
Not ideal for: People trimming large areas who need stated runtime, a wider cutting path, or unambiguous warranty details.
- Power source:Battery powered
- Battery:40V MAX lithium-ion, 2.0 Ah
- Batteries included:1
- Cutting width:13 inches
- Maximum speed:8,500 RPM
- Weight:7.8 pounds
- Line feed:Automatic Feed Spool
- Warranty:3-year limited warranty stated in description; item details also mention 2 years
Our verdict“Choose the LST136 for adjustable cordless trimming and edging on a modest lawn, but look elsewhere if runtime or warranty clarity is a priority.”
WORX WG163 20V Cordless 2-in-1 String Trimmer and Lawn Edger
The WORX WG163 puts maneuverability ahead of raw cutting capacity. At 5.5 pounds with a 12-inch cutting width, it is lighter and narrower than the BLACK+DECKER LST136, making it appealing for small lawns, borders, and regular touch-ups rather than clearing broad, overgrown areas. Its tilting head and support wheels help guide edging along uneven ground, while push-button line feeding avoids the bump-feed routine. The package lists two 20V batteries and a charger, giving buyers a spare to swap in, although actual runtime is not stated. The main limitation is its 0.065-inch line: compared with the Greenworks 24V’s 0.080-inch line specification, it is less suited to heavy or coarse growth. This is the more targeted choice for neat edges, not demanding brush control.
Pros:- Converts from trimmer to lawn edger.
- Tilting head and support wheels help guide edging over uneven terrain.
- Push-button line feed avoids bumping.
- Includes two 20V lithium-ion batteries and a charger.
Cons:- The 0.065-inch line is less suited to heavy-duty trimming than thicker line options.
- Its 12-inch cutting width covers less ground than the BLACK+DECKER LST136’s 13-inch path.
- Runtime is not specified and varies with battery charge.
Best for: Owners of compact yards who want a light trimmer that can edge paths and borders with wheel support and a spare battery.
Not ideal for: People tackling thick weeds or large areas who need heavier line, a wider cutting path, or predictable runtime information.
- Power source:Battery powered
- Battery voltage:20V
- Batteries included:2 lithium-ion batteries
- Cutting width:12 inches
- No-load speed:7,600 rpm
- Weight:5.5 pounds
- Line diameter:0.065 inches
- Included accessories:20V charger, trimmer spool, support wheels, safety guard
Our verdict“Choose the WG163 for light, controlled trimming and wheel-guided edging in a compact yard, not for thick weeds or fast coverage.”
Milwaukee 2825-20ST 18V Cordless Brushless String Trimmer with Attachment Capability (Tool Only)
The Milwaukee makes more sense as a multi-tool power head than as a simple replacement for a basic lawn trimmer. Its brushless motor reaches up to 6,200 RPM, while the adjustable 14–16-inch swath lets you favor faster coverage or more controlled trimming. It also accepts compatible edger, hedge-trimmer, and pole-saw attachments, which gives it broader yard-maintenance potential than the BLACK+DECKER BESTE620, a corded trimmer-and-edger focused on those two jobs.
The tradeoff is a 12.7-pound tool-only package: buyers need compatible batteries and a charger, and should be comfortable handling more weight than a lightweight corded model. I’d choose this for an existing Milwaukee owner who wants one power head across several tasks, not someone seeking the simplest or lightest grass trimmer.
Pros:- Brushless motor reaches up to 6,200 RPM for demanding trimming.
- Adjustable 14–16-inch cutting swath offers a choice between control and coverage.
- Compatible with edger, articulating hedge-trimmer, and pole-saw attachments.
- Reaches full throttle in under one second.
Cons:- Battery and charger are not included.
- At 12.7 pounds, it is heavier than lightweight options such as the BLACK+DECKER BESTE620.
- Its attachment versatility is less useful to buyers who only need a trimmer.
Best for: Milwaukee battery-system owners who want a powerful trimmer that can also run compatible yard-care attachments.
Not ideal for: Buyers who need a complete cordless kit, prefer a lightweight tool, or only need to trim a small lawn.
- Power source:Battery powered
- Motor:Brushless
- Speed:0–4,900 / 0–6,200 RPM
- Cutting width:14–16 inches
- Line diameter:0.080 / 0.095 inches
- Weight:12.7 pounds
- Attachment compatibility:Edger, articulating hedge trimmer, and pole saw
- Included configuration:Tool only; battery and charger not included
Our verdict“Choose the Milwaukee if you already own compatible batteries and want one power head for trimming and other yard tasks.”
24V Cordless Weed Wacker, 2 x 4.0Ah Battery Powered Weed Eater with Wheel
This 24V trimmer prioritizes low weight and reach over the broad cutting path of a conventional string trimmer. At about 3.5 pounds according to the listed specs, with a telescopic pole adjustable from 33 to 47 inches, it is aimed at users who want an easier-to-handle tool for light grass and precise edging. Its 5-inch-in-class cutting width is much narrower than the 14-inch BLACK+DECKER BESTE620, so it may take longer to cover open lawn but offers a more controlled approach around smaller areas.
The five replaceable blade types and two included 4.0Ah batteries add flexibility, though the listed 40–60-minute runtime is not a promise of that duration during heavy work. Despite the title, the supplied details do not confirm a wheel attachment. I’d skip it for thick growth or large lawns where a wider cutting swath matters more.
Pros:- Lightweight design supports easier handling for short trimming sessions.
- Telescopic pole adjusts from 33 to 47 inches to suit different users.
- Five replaceable blade types support different light-duty trimming tasks.
- Includes two 24V 4.0Ah batteries with hot-swap capability.
Cons:- The 6-inch cutting width covers far less ground per pass than the BLACK+DECKER BESTE620.
- Heavy-duty runtime is limited to a stated 40–60 minutes per charge.
- A wheel attachment is mentioned in the title but is not confirmed in the supplied product details.
Best for: People who want a light, adjustable tool for small yards, touch-ups, and careful trimming around beds or obstacles.

BLACK+DECKER 14-Inch Electric String Trimmer (BESTE620)
The BESTE620 is a practical choice for buyers who want steady corded power and a straightforward way to switch between grass trimming and edging. Its 6.5-amp motor and 14-inch cutting width suit routine work around a modest lawn, while the wheeled edge guide helps keep edging lines controlled. Unlike the cordless EGO Power+ MST1501, it does not depend on battery runtime, but it does need an outlet and an extension cord throughout the job.
The EASYFEED button advances line without bumping the head, and the 5.3-pound body is substantially lighter than the Milwaukee 2825-20ST. That makes it easier to maneuver, though its cord restricts movement and its cutting width is narrower than the EGO’s 15 inches. I’d favor it for nearby lawns with accessible outlets, not for large or disconnected areas.
Pros:- Corded power avoids battery-runtime limits during routine yard work.
- Combines string trimming and wheeled edging in one tool.
- EASYFEED button advances line without bumping the head.
- Light 5.3-pound design includes adjustable handles and height positions.
Cons:- Requires an outlet and extension cord, restricting movement around the yard.
- The 14-inch cutting width is narrower than the EGO Power+ MST1501’s 15-inch swath.
- Less suited to properties with distant or obstructed trimming areas.
Best for: Homeowners with a small or medium lawn, an accessible outdoor outlet, and a need for both trimming and edging.
Not ideal for: People trimming far from outlets or around a large property where managing an extension cord would slow the job.
- Power source:Corded electric
- Motor:6.5 amp
- Cutting width:14 inches
- Functions:String trimming and edging
- Line feed:EASYFEED button
- Weight:5.3 pounds
- Cord feature:Cord retention system
- Warranty:2-year limited warranty
Our verdict“Choose the BESTE620 for light, outlet-accessible yards where corded operation and easy edging matter more than cordless freedom.”
EGO Power+ MST1501 Multi-Head String Trimmer Combo Kit with 5.0Ah Battery and Charger
The EGO MST1501 is the most ready-to-work cordless choice here: the kit includes its power head, 15-inch trimmer attachment, 56V 5.0Ah battery, and charger. That makes it a more complete purchase than the Milwaukee 2825-20ST, which is sold tool-only. The brushless motor, .095-inch dual-twist line, and Rapid Reload head are aimed at buyers who want a substantial cutting path and simpler line replacement, while the stated runtime reaches up to 45 minutes per charge.
That runtime can still fall short for a large or demanding property, and the 12-pound weight makes it less appealing for users seeking an especially light trimmer. Its IPX4 weather resistance adds flexibility for typical outdoor conditions, but other attachments and additional batteries are sold separately. I’d pick it over the Milwaukee when a complete kit matters more than reusing an existing battery system.
Pros:- Includes power head, trimmer attachment, 56V battery, and charger.
- 15-inch cutting width covers more ground per pass than the BESTE620’s 14-inch swath.
- Rapid Reload head makes replacing .095-inch line simpler.
- Brushless motor and IPX4 weather-resistant design.
Cons:- Up to 45 minutes of runtime may not cover larger trimming jobs.
- At 12 pounds, it is a substantial tool for extended use.
- Additional batteries and compatible attachments are sold separately.
Best for: Buyers seeking a capable cordless trimmer kit with battery and charger included, plus compatibility with EGO’s multi-head system.
Not ideal for: People with large, demanding trimming jobs who need longer runtime, or anyone prioritizing a lightweight tool.
- Power source:Battery powered
- Motor:Brushless
- Battery:56V 5.0Ah ARC Lithium, included
- Runtime:Up to 45 minutes
- Cutting width:15 inches
- Trimmer line:.095-inch dual-twist line
- Weather resistance:IPX4
- Weight:12 pounds
- Warranty:5 years for tool; 3 years for battery
Our verdict“Choose the EGO if you want a complete, wide-cutting cordless kit and can work within its stated runtime and weight.”
How We Picked
I compared these trimmers on the factors that change day-to-day ownership: power source and practical reach, cutting width, included battery and charger, handling, and the type of cutting system. I also looked at maintenance demands and versatility, including line feeding, blade-based designs, edging functions, and attachment capability. A trimmer that arrives ready to work earns a different place from a tool-only model that depends on an existing battery platform.
The ranking favors useful balance over the longest feature list. Ready-to-use kits and broadly useful performance rank ahead of specialized tools, while corded picks remain relevant for compact yards where outlets are close. Models with unusual blade systems, multiple functions, or attachment support are judged by whether those features suit a clear buyer need—not simply by how many features they advertise. Because yard size, vegetation, and existing batteries vary, the best choice for one reader may not be the top-ranked pick for another.
Factors to Consider When Choosing Best Electric Grass Trimmers
Before choosing, match the trimmer to your yard’s layout and the work you expect it to do. Power source, cutting system, and battery compatibility can matter more than a headline feature such as cutting width. These factors can help you avoid paying for capabilities you will not use—or buying a tool that makes routine trimming frustrating.
Match the Power Source to Yard Layout
A corded trimmer suits a smaller, fairly open yard where an outlet is within safe reach and the cord will not cross a busy work area. Its steady connection removes battery charging and runtime from the task, but you must keep the cord clear of the cutting head and avoid snagging it on trees or beds. Cordless models are easier to move around obstacles and between separate lawn areas, though their working time depends on battery capacity, vegetation, and how aggressively you cut. A common mistake is choosing cordless for a tiny yard without checking whether the kit includes a battery, or choosing corded for a large plot with no convenient outlet. If your yard is split by paths, fences, or planting beds, freedom of movement may matter more than a wider cutting path.
Treat Battery Compatibility as Part of the Purchase
Battery voltage alone does not tell you whether a pack will fit another brand’s tools; compatibility usually stays within a manufacturer’s platform and product family. If you already own cordless equipment, check the exact battery system before buying a tool-only trimmer such as the Milwaukee 2825-20ST. A kit with a battery and charger costs less in hassle for a first-time buyer, while a bare tool can make sense when compatible packs are already in your shed. Look at battery capacity as a runtime clue, not a guaranteed number of minutes: thick grass and repeated edging can drain a pack faster than light trimming. Buyers with larger yards may value a spare battery more than a modest increase in cutting width. Also check whether the charger and battery are included in the specific package being sold.
Choose a Cutting System You Can Maintain
Most electric string trimmers use replaceable line, but feed mechanisms differ and can affect how often work pauses for adjustment. Blade-based systems may suit buyers who want a different approach to line replacement, though replacement blades are a separate consumable to check for availability and cost. Do not assume that a 4-in-1 design or blade bundle makes a trimmer a better choice for ordinary grass edging; extra functions can add parts and setup steps. Think about the vegetation you cut: lawn edges and light weeds call for different demands than dense, woody growth. Before buying, find out how the cutting element is replaced and whether the needed line or blades are easy to source. A simpler system is often preferable if you want routine maintenance to stay quick.
Balance Cutting Width Against Control
A wider cutting path can reduce passes across open strips, but it may feel less nimble around narrow borders and closely spaced plants. A narrower head can make careful work easier, especially where you need to trim beside a fence or avoid striking flowers and young shrubs. Cutting width is only one part of productivity: motor behavior, line feed, and the user’s control over the head also affect how quickly a job gets done. Buyers sometimes focus on the largest advertised width and overlook how the tool feels when repeatedly lifted or turned. For a mixed yard, favor a manageable balance rather than selecting strictly by inches. If most of your work is open lawn, a wider path has a clearer advantage.
Decide Whether Edging and Attachments Will Get Used
A pivoting head or dedicated edging mode can tidy lawn borders without requiring a separate tool, which is useful when edging is part of every mow. These features do not replace a dedicated edger for every job, and a conversion mechanism adds another step that should feel intuitive to the buyer. Attachment-capable models can extend a compatible power head to other yard tools, but only make financial and storage sense if you plan to buy and use those attachments. Check which attachments are supported rather than assuming every accessory will fit. Buyers who only trim grass around obstacles may be better served by a lighter, simpler trimmer. Pay for versatility when it replaces equipment you would otherwise own, not just because the option exists.
Check Weight, Balance, and Included Gear
Tool weight affects comfort over a full yard, but balance matters too: a well-balanced trimmer can feel easier to guide than a lighter tool with a head-heavy feel. Look for adjustable handles or a shaft arrangement that can suit your reach and trimming posture. The package contents also shape readiness: a battery, charger, shoulder support, guards, and cutting accessories can determine whether the tool is usable straight away. Do not compare a tool-only model with a complete kit as if they offer the same starting point. If you have limited storage, a compact design may be more useful than a system built for many attachments. Where product listings do not clearly state weight or included gear, confirm those details before choosing.
Frequently Asked Questions
Should I choose a corded trimmer or a cordless one for a small yard?
For a small yard close to an outlet, a corded model can be a sensible choice because you do not need to manage battery charge or runtime. It becomes less convenient if the cord must pass around many obstacles or across walkways. A cordless trimmer is easier to move and store without a cord, but check whether the kit includes its battery and charger. The BLACK+DECKER corded options in this roundup suit outlet-accessible spaces, while battery kits make more sense when freedom of movement matters more. Base the choice on your yard’s layout, not just its size.
Is a tool-only cordless trimmer a good buy if I do not own that brand’s batteries?
Usually, a tool-only model is a better fit for someone who already owns compatible batteries and a charger. If you need to buy those separately, compare the complete setup you will need before deciding; the trimmer itself is only part of the system. Check the exact battery platform and compatibility rather than relying on voltage as a match. For example, the Milwaukee 2825-20ST is explicitly a tool-only option, unlike bundled kits in this lineup. A complete kit is often the simpler starting point for a new cordless-tool owner.
Does a larger cutting width mean I will finish trimming faster?
A larger cutting width can reduce the number of passes on open stretches, but it does not guarantee faster work across an entire yard. Tight corners, planting beds, and narrow edges may call for a smaller, more controllable head. Cutting performance and line feed also affect how often you need to stop or retrace an area. Consider where most of your trimming happens, not just the broadest patch of grass. A wider model such as the 14-inch BLACK+DECKER options has a clearer advantage on open ground than around delicate borders.
Are blade-based or multi-function trimmers worth choosing over standard string models?
They can be a good fit when their particular cutting system or added functions solve a task you do often. A blade-based design changes what you need to keep on hand, so check replacement-part availability before choosing it. Multi-function models can also save space or reduce tool changes, but extra functions may add setup and maintenance. For ordinary grass trimming, a straightforward string model may be easier to keep ready. Choose a specialized design for a clear use case rather than assuming more functions mean better results.
What should I prioritize if I want one trimmer for both trimming and edging?
Start by checking how easily the head changes between trimming and edging, and whether the tool feels manageable in both positions. A built-in edging mode can save storage space and avoid swapping tools, but it may not match a dedicated edger for frequent, heavy edging. The WORX WG163 and several BLACK+DECKER models offer combination functionality in this roundup, while the right choice still depends on your yard’s edge length and finish expectations. Also check the cutting system and battery or cord setup, since both affect how practical it is to use the tool for a full yard. If edging is occasional, a convenient conversion feature may be enough.
Conclusion
For most buyers seeking a ready-to-use cordless option, I would start with the Husqvarna 320iL as the best overall pick. My best value direction is the Greenworks 24V 13-inch kit for shoppers who want a battery-and-charger bundle and are comfortable with its blade-based system; compare it with the 40V Greenworks if you prefer a string-trimmer setup. Beginners with a small yard and a nearby outlet may find the BLACK+DECKER BESTA510 straightforward, while buyers who want a compact trim-and-edge tool should look at the WORX WG163. For a premium, expandable system, the EGO Power+ MST1501 is the pick for shoppers who value its multi-head format and included 5.0 Ah battery. If you already own compatible Milwaukee batteries or need attachment capability, the Milwaukee 2825-20ST serves that specific need; for a simple corded 14-inch path, consider the BLACK+DECKER BESTE620. Match the recommendation to your power access, existing batteries, and how much of the yard you plan to trim.
