Battery-powered string trimmers range from light-duty edging tools to wider-cutting models for larger yards. My best overall pick is the EGO POWER+ ST1502SA, which pairs a 15-inch cutting path with a battery and charger; the Greenworks 60V 16-inch trimmer stands out for broader coverage, while the WORX WG163 suits buyers who want a simple trimmer-to-edger setup. The main tradeoffs are cutting capacity and battery platform versus weight, included battery capacity, and the cost of buying into a new system. Combo kits can add value, but they may not be the best fit if you already own compatible batteries. Read on for the full comparison and guidance on which type makes sense for your yard.

Key Takeaways
- The EGO POWER+ ST1502SA leads as the all-around pick with a 15-inch cutting path and a kit that includes a battery and charger; buyers still need to weigh its battery platform against lighter-duty 20V options.
- The Greenworks 60V model is the widest-cutting option in this lineup at 16 inches, making it a stronger match for larger areas than the 12-inch models, but its greater capacity may be more than small lawns need.
- The two Greenworks 40V listings offer different buying propositions: the combo adds a blower, while the standalone kit centers on the trimmer; choose based on whether the extra tool is useful to you.
- Several 20V models prioritize flexibility over cutting width. WORX, BLACK+DECKER, SEYVUM, and HEYWORK combine trimming with edging, while ALSO GO and Boltarc add brush-cutting claims that call for checking the tool’s intended materials and attachments.
- Battery details change the value equation. The CRAFTSMAN kit includes a 4Ah battery and lists up to 63 minutes of runtime, while the 20V two-battery kit supplies two 2.0Ah packs; runtime claims and battery capacity are not directly interchangeable.

More Details on Our Top Picks
EGO POWER+ 15″ Cordless Weed Trimmer with Battery and Charger – ST1502SA
The EGO POWER+ ST1502SA is my strongest all-around pick here for buyers who want a battery trimmer with a wider path and more substantial cutting line. Its 15-inch swath and 0.095-inch line cover more ground per pass than the 12-inch Greenworks models, a useful advantage around larger lawns and overgrown borders. The included 2.5Ah battery is rated for up to 45 minutes, and the brushless motor, variable speed, and Rapid Reload head add practical convenience without relying on a separate tool for line changes.
The tradeoff is a more limited kit: unlike the Greenworks 40V trimmer-and-blower combo, it does not include a second yard tool. Runtime is also a stated maximum, not a guarantee for demanding conditions. I’d favor this EGO for a homeowner prioritizing trimming reach and an expandable 56V battery platform, but skip it if a combo kit or a smaller, lighter setup matters more.
Pros:- 15-inch cutting width covers more ground per pass than the 12-inch options here.
- 0.095-inch professional-grade line is suited to tougher trimming than thinner-line models.
- Rapid Reload head simplifies replacing cutting line.
- Included 2.5Ah battery works across EGO 56V tools.
Cons:- Does not include a blower or another yard-care tool, unlike the Greenworks combo.
- Up to 45 minutes of runtime may be insufficient for extended heavy cutting.
- Wider cutting head is less suited to precise work in cramped garden beds.
Best for: Homeowners with medium or larger yards who want a wide cutting path, thicker line, and access to EGO’s 56V tool platform.
Not ideal for: Buyers seeking a trimmer-and-blower bundle or a compact tool for small, lightly maintained spaces.
- Power source:Battery powered
- Voltage platform:EGO 56V ARC Lithium
- Battery included:2.5Ah lithium-ion
- Cutting width:15 inches
- Cutting line:0.095 inch
- Speed:5,800 rpm
- Runtime:Up to 45 minutes
- Weight:7.4 pounds
- Warranty:5-year tool; 3-year battery
Our verdict“Choose the EGO if you want this lineup’s strongest balance of cutting width, line thickness, and battery-platform flexibility.”
Greenworks 40V 12 in String Trimmer & 390 CFM Blower Combo, 2.0 Ah Battery
This Greenworks 40V combo makes the most sense when trimming is only half the cleanup. The kit pairs a 12-inch, 0.065-inch auto-feed trimmer with a blower rated at 390 CFM and 110 mph, so one battery system handles lawn edges and loose debris on hard surfaces. Compared with the EGO ST1502SA, its trimmer has a narrower path and thinner line, but the included blower gives it a broader job-to-job role.
The compromise is that the bundled convenience does not make this the strongest choice for dense weeds: the EGO’s wider swath and thicker line are better suited to more demanding cutting. The listed battery is 2.0Ah, and the product data does not give a clear trimmer runtime under specific conditions. I’d pick this set for routine edging plus driveway or patio clearing, not as a heavy-duty trimmer purchase.
Pros:- Includes both a 12-inch trimmer and a 390 CFM blower.
- Auto-feed line removes the need to bump the trimmer head to advance line.
- 40V battery is part of a broader Greenworks tool platform.
- Blower offers variable-use convenience with cruise control.
Cons:- The 0.065-inch line and 12-inch path are less suited to heavy cutting than the EGO ST1502SA.
- The included battery is 2.0Ah, limiting capacity compared with larger-battery kits.
- Buying a combo adds a blower even for shoppers who only need a trimmer.
Best for: Homeowners who want one battery kit for light-to-moderate trimming and blowing leaves or debris from patios and driveways.
Not ideal for: People regularly cutting dense weeds or tall, tough growth who would benefit from the EGO’s wider path and thicker line.
- Power source:Battery powered
- Voltage:40V
- Battery included:2.0Ah lithium-ion
- Trimmer cutting width:12 inches
- Trimmer line:0.065 inch, auto-feed
- Trimmer speed:7,500 rpm
- Blower airflow:390 CFM
- Blower air speed:110 mph
- Kit contents:Trimmer, blower, battery, and charger
Our verdict“Choose this Greenworks kit if a useful blower matters as much as routine trimming and edging.”
Greenworks 40V Cordless String Trimmer with 12-Inch Cutting Path, 2.0 Ah Battery and Charger
The Greenworks 40V 12-inch trimmer is a straightforward choice for routine grass and light weeds, with the battery and charger included rather than requiring a separate platform purchase. Its automatic line feed advances line without the bump-feed technique, and variable speed gives the operator some control over power use. Compared with the Greenworks trimmer-and-blower combo, this kit keeps the purchase focused on trimming; compared with the EGO ST1502SA, it gives up cutting width and thicker line for a more modest task profile.
That distinction matters: this model is described for lighter growth, not persistent dense weeds. Its 2.0Ah battery also has less capacity than the EGO’s 2.5Ah pack, and the listed 12-pound weight is heavier than some compact battery trimmers. I’d choose it for regular lawn-edge maintenance within the Greenworks 40V system, but not for overgrown areas or buyers wanting a bundled blower.
Pros:- Battery and charger are included for a ready-to-use setup.
- Automatic line feed advances line without bumping the head.
- Variable speed lets users adjust output for lighter trimming.
- Three-year limited warranty covers both tool and battery.
Cons:- Designed for grass and light weeds rather than heavy-duty cutting.
- 12-inch cutting path is narrower than the EGO ST1502SA’s 15-inch path.
- Listed 12-pound weight may feel less manageable than lighter compact alternatives.
Best for: Greenworks 40V owners and homeowners maintaining lawn edges, grass, and light weeds with a complete battery-and-charger kit.
Not ideal for: Buyers facing thick or overgrown weeds, or those seeking a blower bundle or a wider cutting path.
- Power source:Battery powered
- Voltage:40V
- Battery capacity:2.0Ah
- Battery and charger:Included
- Cutting width:12 inches
- Cutting line:0.065-inch dual line
- Speed:7,500 rpm
- Weight:12 pounds
- Warranty:3-year limited tool and battery
Our verdict“Pick this Greenworks model for ordinary grass and light-weed maintenance, not demanding overgrowth.”
SEYVUM 20V Cordless String Trimmer and Edger, 12-Inch
The SEYVUM 20V trimmer earns its place for buyers who want edging flexibility built into the tool. It converts to a wheel edger, and its cutting head adjusts through 90 degrees, helping reach awkward borders and work at different angles. Two included 2.0Ah batteries give it a spare pack, unlike the single-battery Greenworks 40V trimmer, while automatic line feed avoids manual bumping. The EGO ST1502SA is the better fit for a wider cut and thicker line; SEYVUM is more about positioning and edging convenience.
There are limits to that versatility. Runtime is not specified, so I can’t compare its working time confidently with EGO’s stated up-to-45-minute figure. Its 18-month warranty is also shorter than the Greenworks model’s three-year coverage. I’d favor SEYVUM for homeowners who frequently switch between trimming and crisp walkway edges, but skip it if runtime certainty or a longer warranty ranks higher.
Pros:- Converts between string trimming and wheel edging.
- 90-degree adjustable cutting head and 180-degree auxiliary handle support varied working positions.
- Two 2.0Ah batteries and a fast charger are included.
- Automatic line feed and eight included spool lines simplify routine upkeep.
Cons:- Runtime is not specified, making job planning harder than with the EGO ST1502SA.
- 18-month warranty is shorter than the Greenworks 40V trimmer’s three-year coverage.
- 12-inch cutting width offers less coverage per pass than the EGO’s 15-inch path.
Best for: Homeowners who regularly edge sidewalks and beds and want an adjustable head plus a spare battery in the kit.
Not ideal for: Buyers prioritizing stated runtime, longer warranty coverage, or a wider cutting path for substantial overgrowth.
- Power source:Battery powered
- Voltage:20V
- Batteries included:2 × 2.0Ah
- Cutting width:12 inches
- Motor speed:8,000 rpm
- Cutting head adjustment:90 degrees
- Auxiliary handle adjustment:180 degrees
- Weight:8 pounds
- Warranty:18 months
Our verdict“Choose SEYVUM if adjustable edging and a second battery matter more to you than a published runtime or longer warranty.”
20V Cordless String Trimmer with Two 2.0Ah Batteries and Charger
This 20V cordless trimmer is the storage-minded choice: its folding shaft and rotating handle make it easier to put away and position in tight areas than the full-length EGO ST1502SA. It also changes between trimming and edging, with an adjustable head and automatic line feed. Two 2.0Ah batteries are included, and the listed up-to-30-minute runtime gives buyers a practical, if limited, guide for smaller maintenance sessions.
Its 9,500 RPM motor sounds brisk, but the product guidance warns against excessively thick or dense grass because the line may break. That makes it a poor substitute for the EGO’s wider cut and thicker line on tougher growth. I’d choose this model for a compact shed, small yard, or detail work around obstacles; skip it if you need extended runtime or routinely cut through heavy weeds.
Pros:- Folding shaft helps reduce storage demands.
- Two 2.0Ah batteries and a charger are included.
- Adjustable head and rotating handle support tight-space trimming and edging.
- Automatic line feed and up-to-30-minute runtime suit short maintenance sessions.
Cons:- Up-to-30-minute runtime may not cover larger properties.
- Instructions caution against excessively thick or dense grass because line may break.
- 12-inch cutting width is narrower than the EGO ST1502SA’s 15-inch path.
Best for: Apartment, townhouse, and small-yard owners who need a foldable trimmer for light maintenance and edging in confined storage.
Not ideal for: People with large properties, dense grass, or heavy weeds that call for longer runtime and more robust cutting capacity.
- Power source:20V battery powered
- Batteries included:2 × 2.0Ah lithium-ion
- Cutting width:12 inches
- Motor speed:9,500 rpm
- Runtime:Up to 30 minutes
- Functions:String trimmer and edger
- Line feed:Automatic
- Dimensions:40 × 8 inches
- Color:Lime green
Our verdict“Choose this model for compact storage and light trimming in a small yard, not for long or heavy cutting sessions.”
WORX WG163 20V Cordless 2-in-1 String Trimmer and Lawn Edger
The WORX WG163 is a strong fit for lawns where clean borders matter as much as trimming. Its tilting head, support wheels, and adjustable spacer guard help guide edging along paths and uneven ground, while the push-button line feed avoids the tap-to-advance routine. At 5.5 pounds, it is also the lightest of the two 20V convertible trimmers from WORX and BLACK+DECKER in this group. The practical advantage over the BLACK+DECKER LST300 is its two included batteries, which give you a spare to swap in, though they do not guarantee uninterrupted work if both need charging. The tradeoff is a narrower 12-inch swath and thin 0.065-inch line, making it better for routine lawn edges than heavy, overgrown patches.
Pros:- Converts between trimming and edging, with wheels to guide edge work
- Two 20V batteries and a charger are included
- Push-button line feed avoids bumping the spool
- Tilting head and spacer guard help control trimming near obstacles
Cons:- 12-inch cutting width covers less ground per pass than wider models
- 0.065-inch line is better suited to ordinary grass than tough growth
- Two batteries add flexibility but do not specify runtime or charging time
Best for: Homeowners with paths, borders, or uneven lawn edges who want a lightweight trimmer and a spare battery.
Not ideal for: People clearing dense, woody weeds or trimming large properties that call for a wider cutting path and heavier-duty line.
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- No-load speed:7,600 rpm
- Weight:5.5 pounds
- Line diameter:0.065 inches
- Batteries included:Two lithium-ion batteries
- Included accessories:Charger, trimmer spool, support wheels, and safety guard
Our verdict“Choose the WORX WG163 for guided edging and easy handling, especially if having a spare battery matters more than a wide cutting swath.”
BLACK+DECKER 20V MAX Cordless String Trimmer and Edger (LST300)
The BLACK+DECKER LST300 prioritizes straightforward operation over extra edging controls. Its automatic feed spool advances line without bumping, and the tool converts to a wheeled edger for basic border work. With adjustable height and handle positions, it offers useful fit options, though it weighs 5.7 pounds—slightly more than the WORX WG163. The clearest difference is the kit: BLACK+DECKER includes one 2.0 Ah battery, while the WORX comes with two batteries and more edging guides. That makes the LST300 a sensible choice for smaller lawns where one battery is enough and a simple feed system is appealing. For longer sessions, the limited included capacity is a real constraint, and its 12-inch swath is less suited to covering broad areas quickly.
Pros:- Automatic line feed advances line without bumping
- Converts to a wheeled edger
- Adjustable handle and height help tailor the fit
- Includes a 2.0 Ah battery and charging base
Cons:- Only one 2.0 Ah battery is included, which may limit longer jobs
- 12-inch cutting width means more passes than wider trimmers
- At 5.7 pounds, it is slightly heavier than the WORX WG163
Best for: Owners of small to medium lawns who want a basic trimmer-edger with automatic line feeding and adjustable fit.
Not ideal for: People with larger yards or extended trimming sessions who need more battery capacity or a spare battery in the box.
- Model:LST300
- Power source:Battery powered
- Battery:One 2.0 Ah lithium-ion battery
- Cutting width:12 inches
- Speed:6,200 rpm
- Weight:5.7 pounds
- Dimensions:36.23 x 8.5 inches (L x W)
- Warranty:2-year limited warranty
Our verdict“Pick the LST300 for uncomplicated trimming and edging on a modest lawn, but favor the WORX WG163 if you want a spare battery and more edging guidance.”
CRAFTSMAN V20 String Trimmer and Lawn Edger Kit with 4Ah Battery and Charger (CMCST901M1)
The CRAFTSMAN V20 stands out in this group for pairing a 4.0 Ah battery with a 13-inch cutting swath and two speed settings. The listed runtime is up to 63 minutes on low speed, so it is aimed at covering more lawn between charges rather than being the most compact choice. Its turn-to-edge function keeps trimming and edging in one tool, and the speed settings let you favor runtime or cutting performance. Compared with the BLACK+DECKER LST300, this kit offers a larger battery and wider path, but its runtime claim is specifically tied to low speed; the available product data does not give a weight. That makes the claimed duration a useful guide, not a guarantee for thick growth or continuous high-speed work.
Pros:- Includes a 4.0 Ah battery and charger
- 13-inch cutting width covers more ground per pass than 12-inch models
- Two speed settings let users favor runtime or cutting performance
- Turns to edge without requiring a separate tool
Cons:- The up-to-63-minute runtime is specified for low speed, not every use case
- Only one battery is included
- Product data does not provide a weight for comparing handling
Best for: Homeowners with medium-sized lawns who want a wider cut and a larger included battery for longer trimming sessions.
Not ideal for: Buyers who need a verified lightweight tool or dependable runtime figures for demanding, high-speed cutting; the listed duration applies at low speed.
- Power source:Battery powered
- Battery:One 4.0 Ah V20 lithium-ion battery
- Cutting width:13 inches
- Runtime:Up to 63 minutes on low speed with the CMCB204 4.0 Ah battery
- Speed settings:Two
- Line diameter:0.065 inches
- Edging:Turn-to-edge functionality
- Battery platform:CRAFTSMAN V20
Our verdict“Choose the CRAFTSMAN V20 if a wider cut and larger battery matter more than a second battery or a confirmed weight.”
HEYWORK 20V Cordless String Trimmer and Edger, 12-Inch
The HEYWORK’s main differentiator is its kit: it includes two 4.0 Ah batteries, a charger, and eight replacement spools. That is a generous set of consumables and battery capacity compared with the one-battery BLACK+DECKER LST300 and the two-battery WORX WG163, whose battery capacities are not specified here. Its 8,000 RPM motor and automatic line feed suit routine trimming without stopping to bump the spool, and it switches between trimming and edging. The tradeoffs are a 12-inch cutting width and a 6.3-pound weight, making it heavier than either of those alternatives. The product data also lists battery life as “40 years,” an implausible figure that should not be treated as a usable runtime estimate.
Pros:- Includes two 4.0 Ah lithium-ion batteries and a charger
- Eight replacement spools are included
- Automatic line feed reduces interruptions
- Converts between trimming and edging
Cons:- Listed battery life of 40 years is not a credible runtime figure
- At 6.3 pounds, it is heavier than the WORX WG163 and BLACK+DECKER LST300
- 12-inch cutting width is modest for clearing larger areas
Best for: Buyers who want two high-capacity batteries and replacement spools included for recurring lawn maintenance.
Not ideal for: People who need a verified runtime, the lightest handling, or a wider cutting path for larger properties.
- Model number:G-DC2505-HY
- Power source:Battery powered
- Voltage:20V
- Cutting width:12 inches
- Motor speed:8,000 RPM
- Weight:6.3 pounds
- Batteries included:Two 4.0 Ah lithium-ion batteries
- Line feed:Automatic
- Included accessories:Charger and eight replacement spools
Our verdict“The HEYWORK makes sense if the two 4.0 Ah batteries and spare spools appeal, but skip it if you need a trustworthy runtime specification.”
ALSO GO 24V Cordless 3-in-1 Weed Trimmer, Edger, and Brush Cutter
The ALSO GO is less of a conventional line trimmer than the other picks: its three-in-one design includes trimming, edging, and brush-cutting modes, with five interchangeable blade types for different tasks. The adjustable 35-to-47-inch shaft and pivoting head help adapt reach and angle, while the listed 3-pound weight is notably low. Compared with the 12-inch WORX WG163, its 6-inch cutting width will take more passes across open lawn, but the blade options give it a different role for spot work and thicker weeds. Two 24V batteries are included, yet no runtime is provided, so the bundle does not reveal how long the tool can sustain demanding cutting. Buyers focused on fast coverage should choose a wider trimmer instead.
Pros:- Five interchangeable blade types support different yard tasks
- Adjustable shaft extends from 35 to 47 inches
- Pivoting head and auxiliary wheel aid positioning
- Two 24V batteries are included
Cons:- 6-inch cutting width requires more passes than the 12-inch WORX WG163
- Battery runtime is not specified
- Blade-based cutting setup differs from standard string trimmers and may be less convenient for routine line replacement
Best for: Gardeners with varied small-yard tasks who want a lightweight tool for grass trimming, edging, and occasional thicker weeds.
Not ideal for: People maintaining broad lawns or expecting a stated runtime for extended brush-cutting; its 6-inch width slows coverage and battery duration is unspecified.
- Power source:Battery powered
- Motor power:650W
- No-load speed:11,000 RPM
- Batteries:Two 24V 2.0 Ah lithium batteries
- Cutting width:6 inches
- Shaft length:Adjustable from 35 to 47 inches
- Blades:Five interchangeable blade types
- Weight:3 pounds
Our verdict“Choose the ALSO GO for varied, small-area trimming and blade-based tasks, not for quickly covering a large lawn.”
Boltarc 21V Cordless 3-in-1 String Trimmer
The Boltarc earns its place for buyers who want one tool to handle trimming, edging, and light weed clearing. Its 90° rotating head helps shift between tasks, while automatic line feed avoids manual bumping. Compared with the BLACK+DECKER LST136, which offers a much wider 13-inch cutting path, the Boltarc’s 5.8-inch path means more passes across open lawn but may suit detail work around beds and borders. Two included 4.0Ah batteries and a stated maximum runtime of up to 120 minutes give it a generous battery package on paper; actual runtime will depend on workload. The kit also includes a fast charger and eight replacement spools. Its main tradeoff is limited cutting width, and the provided specs do not establish how well its weed-clearing mode handles thick growth.
Pros:- Switches among trimming, edging, and weed-clearing tasks
- 90° rotating head supports changes in cutting angle
- Includes two 4.0Ah batteries, a fast charger, and eight replacement spools
- Automatic line feed reduces manual line adjustments
Cons:- 5.8-inch cutting width covers less ground per pass than the BLACK+DECKER LST136’s 13-inch path
- Up to 120 minutes is a stated maximum, not a workload-specific runtime estimate
- Available specifications do not clarify its capability in thick or tough weeds
Best for: Homeowners with small, detail-heavy yards who want trimming, edging, and occasional weed clearing from one cordless tool.
Not ideal for: People with broad lawns or heavy, dense growth who need a wide cutting path and documented performance under demanding conditions.
- Voltage:21V
- Motor power:500W
- Maximum speed:9,000 RPM
- Cutting width:5.8 inches
- Batteries:Two 4.0Ah batteries
- Maximum stated runtime:Up to 120 minutes
- Cutting head:90° rotating
- Line feed:Automatic
- Included accessories:Fast charger and eight replacement spools
Our verdict“Choose the Boltarc for varied light-duty yard tasks and an accessory-rich battery kit, but pick a wider trimmer for large areas.”
BLACK+DECKER LST136 40V MAX Cordless String Trimmer and Edger, 13-Inch
The LST136 is a strong fit for buyers who want a conventional-width trimmer with control over how hard it works. Its 13-inch cutting path covers more ground per pass than the Boltarc 21V’s 5.8-inch path, and the adjustable power settings let you favor cutting output or battery conservation as the job changes. It also converts to an edger and uses automatic line feed, so edging does not require a separate tool or bumping the head. At 7.8 pounds, its listed weight is useful context for shoppers comparing handling. The compromise is an unspecified runtime, making it harder to plan larger jobs than with the Boltarc’s stated maximum. Product information also gives conflicting warranty periods—two and three years—so buyers should verify the applicable coverage before purchase.
Pros:- 13-inch cutting path covers more ground per pass than the Boltarc 21V
- Adjustable power settings can balance cutting demand and battery use
- Converts from trimmer to edger and feeds line automatically
- Includes a 40V battery and fast charger
Cons:- Runtime is not specified, limiting planning for longer jobs
- Product information conflicts on whether the warranty lasts two or three years
Best for: Homeowners with average-sized yards who want a 13-inch cutting path, edging capability, and power settings for routine trimming.
Not ideal for: Buyers who need a dependable runtime estimate for extended sessions or want clearly stated warranty coverage.
- Voltage:40V MAX
- Battery:2.0Ah lithium-ion
- Cutting width:13 inches
- Maximum speed:8,500 RPM
- Weight:7.8 pounds
- Line feed:Automatic
- Functions:String trimming and edging
- Included components:Battery, fast charger, spool, guard, and auxiliary handle
- Warranty information:Product content states 3-year limited warranty; item details state 2 years
Our verdict“Pick the LST136 for adjustable power and a practical 13-inch path, provided you can confirm warranty terms and accept an unspecified runtime.”
Greenworks 60V Cordless String Trimmer, 16-Inch, with 4.0Ah Battery
For larger yards or tougher grass, the Greenworks stands apart with a 16-inch cutting path and a 60V brushless motor. That wider swath can reduce the number of passes needed compared with the BLACK+DECKER LST136’s 13-inch path, while the brushless design is aimed at delivering strong cutting power. The included 4.0Ah battery, charger, and adjustable shoulder strap make this a more complete setup for longer sessions than a bare-tool purchase. Its Load N’ Go head is another practical distinction, and compatible Greenworks 60V attachments add flexibility for owners already on that platform. The tradeoffs are real: runtime is not specified, and attachment compatibility does not mean attachments are included. Its larger cutting path may also be more than a small, tidy yard needs.
Pros:- 16-inch cutting path can reduce passes compared with the BLACK+DECKER LST136
- Brushless motor is designed for strong cutting performance
- Includes a 4.0Ah battery, charger, spool, and adjustable shoulder strap
- Compatible with Greenworks 60V products and compatible attachments
Cons:- Runtime is not specified
- Compatible attachments may need to be purchased separately
- The 16-inch cutting path may be unnecessary for small or detail-focused yards
Best for: Owners of larger or grassier yards who want a wide cutting path, a brushless motor, and compatibility with Greenworks 60V tools.
Not ideal for: People with compact yards who prefer a smaller cutting path, or shoppers who need a stated runtime and included attachments.
- Voltage:60V
- Motor:Brushless
- Cutting width:16 inches
- Battery capacity:4.0Ah
- Trimmer head:Load N’ Go
- Included accessories:Battery, charger, spool, and adjustable shoulder strap
- Attachment compatibility:Compatible Greenworks attachments
- Platform:Greenworks 60V
- Warranty:4-year limited warranty for tool and battery
Our verdict“Choose this Greenworks for wide-area cutting and access to the 60V platform, but look elsewhere if runtime certainty or included attachments matter most.”
How We Picked
I ranked these battery-powered string trimmers by how well their stated features match common yard needs: cutting-path width, voltage and battery capacity where provided, included charger and batteries, and whether a tool also converts for edging or adds another function. I also weighed practical ownership questions, including compatibility with an existing battery platform, the number of tools in a kit, and whether the setup appears better suited to routine lawn edges or more demanding growth. A wider cut or higher voltage can help with larger jobs, but neither makes a model the right choice for every yard.
The order gives priority to useful capability and kit completeness, then distinguishes products by their intended buyer rather than treating every feature as a universal advantage. That puts the 15-inch EGO first as a balanced standalone kit, the 16-inch Greenworks 60V high for wider coverage, and versatile trimmer-edger models in roles where maneuverability and conversion matter more than maximum cutting width. Product specifications and included equipment vary, so I avoid treating runtime, power, or brush-cutting claims as directly comparable when the listings do not provide matching test conditions.
Factors to Consider When Choosing Batterypowered String Trimmers
Before choosing among these models, match the tool to the work you actually repeat: trimming lawn borders, cutting around obstacles, maintaining a larger area, or switching among yard tools. Battery fit and task type can matter more than a headline voltage or a long feature list.
Match Cutting Width to Yard Size and Obstacles
A wider cutting path covers more ground with each pass, which can reduce time on open edges and larger lawns. It can also feel less nimble around narrow beds, posts, and tight corners, where a smaller head gives you more control. Do not choose solely by the widest number: consider how much of your trimming is open ground versus detail work. A 12-inch model may be a sensible fit for compact yards, while 15- or 16-inch options make more sense when you routinely clear longer stretches. If you have both open sections and delicate planting, prioritize handling and line control alongside width.
Choose a Battery Platform Before Comparing Voltage
Voltage labels alone do not provide a reliable, direct measure of cutting performance across different brands and product designs. Start by checking whether you already own compatible batteries and chargers, since using the same platform can simplify storage and reduce duplicate equipment. If you are starting fresh, compare the battery capacity included with the trimmer and the availability of other tools you might want later. A kit with a larger battery may be more useful for longer sessions, but it can add weight. Treat runtime claims as estimates unless they are measured under the same conditions and with the same workload.
Decide Whether Edging Conversion Is Worth It
A rotating head or trimmer-to-edger conversion can save space and remove the need to own a separate edging tool. That convenience matters most if you regularly make clean borders along sidewalks and driveways. Conversion designs can involve a change in tool angle or balance, so a feature-rich model is not automatically easier to control. If edging is an occasional task, a straightforward trimmer may be a better fit than paying in weight or complexity for extra functions. Check how the tool converts and whether its wheel or guide features suit the edges you maintain.
Read Kit Contents, Not Just the Tool Name
Listings in this group differ in what comes in the box: some include a battery and charger, one combines a trimmer with a blower, and another specifies two 2.0Ah batteries. Those differences affect how ready the kit is for work and how useful it is alongside equipment you already own. A combo is valuable only if you need the second tool; otherwise, it may add bulk without solving your main problem. Check battery capacity, charger inclusion, and compatibility before comparing kits. This is also a good point to confirm that the listed runtime or accessory claims apply to the exact model and package.
Be Realistic About Brush-Cutting Claims
Multi-function tools that advertise brush cutting may appeal to buyers facing more than ordinary lawn edges, but the phrase can cover very different work. Confirm what cutting attachments are included, what materials the tool is designed to handle, and whether the manufacturer requires a specific guard or accessory. Do not assume that a string-trimmer head is suitable for woody stems or dense growth. For routine grass and weeds, a standard trimmer may be lighter and simpler. If tougher vegetation is a regular job, compare the complete tool setup and instructions rather than relying on a broad 3-in-1 label.
Account for Weight, Balance, and Session Length
Battery size, motor placement, shaft design, and cutting-head width all affect how a trimmer feels during repeated passes. A higher-capacity battery can extend a work session but may add weight, which matters when trimming slopes or holding the tool at an angle. If possible, check the listed weight with the battery installed, not just the bare tool. A shoulder strap or adjustable handle can improve comfort, but it cannot compensate for a poor fit. For brief touch-ups, compactness may matter more than capacity; for a larger yard, a better-balanced tool and a spare compatible battery can be more useful.
Frequently Asked Questions
Is a 12-inch trimmer enough for a typical small yard?
For a small lawn with routine grass trimming and a modest number of edges, a 12-inch cutting path can be adequate and easier to steer around beds and obstacles. It may require more passes than the 15- or 16-inch models when clearing long, open borders. Think about the amount of trimming you do in one session, not only the lot size. If most of your work is detail trimming, control may matter more than extra width. If open areas take a long time, the wider options may save effort.
Should I choose a higher-voltage trimmer over a 20V model?
Not by voltage alone. Voltage is one part of a tool’s design, and the listed products also differ in cutting width, battery capacity, kit contents, and intended use. A higher-voltage model may suit a larger workload, but it can be unnecessary for occasional trimming around a compact lawn. Battery compatibility is a practical deciding factor if you already own tools from one platform. Compare the complete kit and the work you need to do rather than assuming voltage directly predicts performance across brands.
Does a trimmer-edger combo replace a dedicated lawn edger?
For routine sidewalk and driveway borders, a convertible trimmer may be enough and can save storage space. A dedicated edger may be a better match if you want to maintain very crisp borders often or have substantial edging work. The models here differ in how they combine trimming and edging, so check the conversion design and any guide-wheel features. A combo tool also means you are handling one machine for multiple tasks, which may involve changing its configuration. Choose based on how often you edge and the finish you expect, not the feature label alone.
How should I compare included batteries and runtime claims?
Start with the battery capacity and number of packs included, then check whether the charger is part of the kit. A larger capacity or spare battery can help with longer sessions, but actual runtime varies with grass density, line condition, cutting width, and technique. The CRAFTSMAN listing states up to 63 minutes with a 4Ah battery, while the two-battery 20V kit includes two 2.0Ah packs; those details do not establish a direct runtime comparison. Treat manufacturer figures as conditional claims, not guaranteed work time. If you already own a compatible pack, account for that before buying another.
When does a 3-in-1 trimmer make sense?
A 3-in-1 model is most appealing when you regularly need its extra functions and want to store fewer separate tools. The ALSO GO and Boltarc listings add brush-cutter capability, but buyers should check which attachments come with the package and what vegetation the tool is designed to cut. Extra functions can add setup steps and may not improve ordinary lawn trimming. For simple grass maintenance, a lighter trimmer-edger can be a more direct choice. Select a multi-function model only if its added tasks match work you actually plan to do.
Conclusion
For the best overall balance, I recommend the EGO POWER+ ST1502SA, whose 15-inch cut and included battery and charger make it a strong standalone choice. Buyers seeking the best value should look at the Greenworks 40V combo if they will use its blower; the standalone Greenworks 40V kit makes more sense when the trimmer is the priority. For a premium, wider-cutting option, the Greenworks 60V 16-inch model is the lineup’s broadest choice. Beginners who want a simple two-in-one approach can start with the WORX WG163, while shoppers who value included battery capacity can compare the CRAFTSMAN kit. For a specific need, pick a compact 12-inch convertible model for tight edges or investigate the ALSO GO and Boltarc only if their added brush-cutting function matches your work. The right choice comes down to yard size, battery compatibility, and whether extra functions will earn their place in your shed.
