The EGO Power+ ST1511T is my best overall pick among the best battery-powered string trimmers, balancing a 15-inch cutting path with a battery and charger included. For demanding work, the EGO ST1623T offers a wider 16-inch path, while the WORX WG170 adds a mini-mower mode for tighter lawn areas. The main tradeoffs are cutting capacity versus runtime, included batteries versus tool-only platform savings, and straightforward trimming versus extra edging or mowing functions. I also weigh whether a trimmer works with batteries you already own, since platform fit can matter as much as the tool itself. Read on for the full breakdown of all 15 options and which one fits your yard and workload.

Key Takeaways
- EGO separates the performance picks: the ST1511T pairs a 15-inch cutting path with a battery and charger, while the ST1623T gives buyers a wider 16-inch path and a larger 4.0Ah battery kit.
- Battery-platform fit changes the value equation: the Makita XRU23Z and DEWALT DCST922B are tool-only, so they make more sense for owners of compatible batteries than for shoppers starting from scratch.
- Included spare batteries favor flexibility, not automatically more power: several 21V and 20V options ship with two batteries, which can reduce downtime, but their cutting capacity and platform support differ from established tool-system models.
- Edging and multi-function designs serve smaller, detailed yards: the WORX WG170 adds mini-mower functionality, while the WG163 and several 2-in-1 picks focus on switching between trimming and edging.
- Cutting width is a useful but incomplete comparison: the lineup spans 12 to 16 inches, but battery availability, tool weight, compatible accessories, and yard size also shape how efficiently a trimmer handles a job.

More Details on Our Top Picks
CRAFTSMAN V20 Cordless String Trimmer and Edger Kit, 13-Inch, with 4.0Ah Battery and Charger (CMCST901M1)
The CRAFTSMAN V20 is my strongest all-around pick here because it pairs a 13-inch cutting swath with an included 4.0Ah battery and charger, rather than relying on a short-lived compact battery. Its Turn-To-Edge function handles lawn borders without requiring a separate tool, while two speed settings let you favor runtime or cutting pace. Compared with the Glenvera, it has a wider swath but comes with one battery instead of two, so the Glenvera may suit buyers who value a ready spare more than coverage per pass. The stated runtime of up to 63 minutes applies on low speed, not every task. Its 0.065-inch line is a lighter-duty choice than the EGO ST1511T’s 0.095-inch line, making the CRAFTSMAN a better fit for routine yard edges than tougher vegetation.
Pros:- Includes a 4.0Ah V20 battery and charger.
- 13-inch cutting width covers more ground per pass than the 12-inch options here.
- Turn-To-Edge function switches between trimming and edging.
- Two speed settings and an adjustable handle support flexible use.
Cons:- The up-to-63-minute runtime is specified for low-speed operation.
- The 0.065-inch line is a lighter-duty choice than the EGO ST1511T’s 0.095-inch line.
Best for: Homeowners seeking one included-battery kit for regular trimming and edging around a modest to medium-sized yard.
Not ideal for: Buyers tackling dense, woody growth or wanting a spare battery included; its 0.065-inch line and single-battery kit are less suited to those needs.
- Model:CMCST901M1
- Power source:Battery powered
- Battery:V20 4.0Ah, 1 included
- Maximum runtime:Up to 63 minutes on low speed
- Cutting width:13 inches
- Line diameter:0.065 inches
- Speed settings:2
- Functions:String trimming and edging
Our verdict“I’d choose the CRAFTSMAN for a capable everyday trim-and-edge kit with a larger included battery, provided heavy brush is not the main job.”
Glenvera 20V Cordless 2-in-1 String Trimmer and Lawn Edger
The Glenvera’s clearest advantage over the CRAFTSMAN V20 is its two included 4.0Ah batteries. Having a spare can keep a larger trimming session moving while the first battery charges, although its stated up-to-60-minute runtime should be treated as a claim rather than a guarantee for every task. The 12-inch swath is narrower than the CRAFTSMAN’s 13 inches, so it may take more passes across open lawn. Glenvera adds an automatic line feed, a four-position adjustable head, and a 180-degree rotating handle; these features offer useful positioning flexibility around edges and obstacles. Its claimed coverage of up to a quarter acre is helpful as a reference, but actual coverage depends on growth and working conditions. I’d favor it for battery flexibility, not for the widest cutting path.
Pros:- Includes two 20V 4.0Ah batteries and a charger.
- Automatic line feed reduces the need for manual line adjustment.
- Four-position adjustable head and 180-degree rotating handle support varied trimming angles.
- Switches between string trimming and lawn edging.
Cons:- Its 12-inch cutting width is narrower than the CRAFTSMAN V20’s 13 inches.
- Runtime and quarter-acre coverage are stated claims and can vary with use.
Best for: Homeowners who want a spare battery included and need a flexible trimmer for mixed trimming and edging around a larger yard.
Not ideal for: Buyers prioritizing the widest cut per pass or wanting a runtime figure established for their specific yard conditions.
- Model:YD2505
- Power source:Battery powered, 20V
- Batteries:2 × 4.0Ah, included
- Cutting width:12 inches
- Motor speed:Up to 9,000 RPM
- Claimed runtime:Up to 60 minutes
- Line feed:Automatic
- Adjustable head:4 positions
- Rotating handle:180°
Our verdict“I’d pick the Glenvera over the CRAFTSMAN when a spare battery and adjustable working positions matter more than a wider swath.”
Cordless Electric String Trimmer and Lawn Edger with Two Batteries
At 5.3 pounds, this trimmer is a sensible choice for buyers who want a light tool for brief edging and touch-ups, and its included safety goggles add a practical extra. It also has a 12-inch cutting width, automatic line feed, and a head that converts between trimming and edging. The main limitation is battery endurance: the specifications list an average battery life of 12 minutes, while the description gives roughly 15–20 minutes per charge. That uncertainty makes it a less dependable choice for longer sessions than the CRAFTSMAN V20, whose low-speed runtime is listed at up to 63 minutes. Two 2.0Ah batteries offer a backup, but do not erase the short runtime per charge. I’d reserve this model for small areas and light work rather than broad or demanding yard maintenance.
Pros:- Light 5.3-pound design is easier to handle for short jobs.
- Includes two 2.0Ah batteries, a charger, and safety goggles.
- Converts between string trimming and edging.
- Automatic line feed and adjustable handle simplify routine operation.
Cons:- Battery life is listed as 12 minutes in the specs but approximately 15–20 minutes in the description.
- Its short stated runtime makes it less suited to longer sessions than the CRAFTSMAN V20.
Best for: People maintaining a small yard or doing brief touch-ups who value low weight, included goggles, and a spare battery.
Not ideal for: Homeowners with large lawns or extended trimming sessions, given the short and inconsistently stated battery runtime.
- Power source:Battery powered, 21V
- Cutting width:12 inches
- Cutting speed:9,000 RPM
- Batteries:2 lithium-ion batteries, 2.0Ah each
- Average battery life:12 minutes
- Stated runtime per charge:Approximately 15–20 minutes
- Weight:5.3 pounds
- Line feed:Automatic
- Functions:String trimmer and lawn edger
Our verdict“I’d choose this lightweight kit for small-yard touch-ups, but not if I needed dependable runtime for a long trimming session.”
EGO Power+ ST1511T 15-Inch Cordless String Trimmer with Battery and Charger
The EGO ST1511T stands apart from the lighter-duty kits with a 15-inch swath, brushless motor, and thicker 0.095-inch line. That combination makes it the strongest fit in this group for buyers who want a more substantial tool for regular trimming, while its telescopic aluminum shaft allows the reach to be adjusted. The standout convenience is POWERLOAD line winding, which replaces manual winding with button-operated loading. Compared with the CRAFTSMAN V20, the EGO cuts a wider path and uses thicker line, but its included 2.5Ah battery has a shorter stated maximum runtime of up to 45 minutes versus the CRAFTSMAN’s up to 63 minutes on low speed. The EGO also weighs 10.3 pounds, so this is not the lightest choice for frequent carrying. Its IPX4 rating adds weather resistance, but does not remove the need to follow the tool’s care instructions.
Pros:- 15-inch cutting width is the widest among these five products.
- 0.095-inch line and brushless motor suit more demanding routine trimming than the lighter-line kits.
- POWERLOAD system winds line with button operation.
- Telescopic aluminum shaft, IPX4 weather resistance, and compatibility with EGO 56V ARC Lithium batteries.
Cons:- At 10.3 pounds, it is heavier than the 5.3-pound compact options.
- The included 2.5Ah battery is rated for up to 45 minutes, less than the CRAFTSMAN V20’s low-speed runtime claim.
- The battery’s stated charging time is 50 minutes.
Best for: Buyers who want a wider cutting path, thicker line, adjustable shaft, and faster line loading for regular yard maintenance.
Not ideal for: People who prioritize a lightweight tool or longer stated runtime per included battery over cutting width and line-loading convenience.
- Model:ST1511T
- Cutting width:15 inches
- Cutting line diameter:0.095 inches
- Motor:High-efficiency brushless
- Speed settings:2
- Battery:2.5Ah lithium-ion, 1 included
- Runtime:Up to 45 minutes
- Charging time:50 minutes
- Weight:10.3 pounds
Our verdict“I’d choose the EGO ST1511T for its wider cut, thicker line, and easy loading, if its weight and shorter stated runtime fit my needs.”
21V Cordless Electric String Trimmer with 2x 2.0Ah Batteries
This 21V trimmer is aimed at small-yard upkeep: it weighs 5.3 pounds, has a detachable shaft for storage, and switches between trimming and edging. Two 2.0Ah batteries provide a spare, with the stated runtime of 15–20 minutes per battery. That setup is more practical for short jobs than a single-battery compact kit, but it remains a poor match for sustained work; the CRAFTSMAN V20 offers a much longer low-speed runtime claim, while the Glenvera includes two larger 4.0Ah batteries. Its 12-inch swath and 9,000 RPM motor are suited to routine light maintenance, not heavy vegetation. Tool-free assembly also helps buyers who want a simple setup and easy storage. I’d choose it for occasional trimming around a small property, not as a substitute for a higher-capacity option on a demanding yard.
Pros:- Lightweight 5.3-pound design helps reduce fatigue during short jobs.
- Includes two 2.0Ah lithium batteries.
- Detachable shaft and tool-free assembly support storage and transport.
- Switches between trimming and edging and offers auto/manual line feed.
Cons:- Stated runtime is 15–20 minutes per battery, limiting continuous work.
- Its 12-inch cutting width is narrower than the EGO ST1511T’s 15-inch swath.
- Designed for small yards and light brush rather than heavy vegetation.
Best for: Small-yard owners who want a lightweight, easy-to-store trimmer for short edging and light vegetation work.
Not ideal for: People maintaining a large yard or cutting heavy brush; its 15–20-minute runtime per battery and light-duty positioning limit longer, tougher jobs.
- Power source:Battery powered, 21V
- Cutting width:12 inches
- Speed:9,000 RPM
- Battery capacity:2 × 2.0Ah lithium batteries
- Runtime:15–20 minutes per battery
- Weight:5.3 pounds
- Functions:Trimmer and edger
- Line feed:Auto/manual
- Shaft:Detachable
Our verdict“I’d pick this model for compact storage and brief small-yard jobs, but would step up to the CRAFTSMAN V20 or Glenvera for longer sessions.”
Lemolifys 3-in-1 Cordless String Trimmer and Edger for DeWalt 20V Batteries
The Lemolifys is a good fit for buyers who already own DeWalt 20V MAX batteries and want one lightweight tool for several kinds of yard cleanup. Its 14-inch cutting path covers more ground per pass than the 12-inch RAXONE and WORX WG170, while detachable wheels let you switch between guided edging and handheld trimming. At just 4 pounds, it is also the lightest option here, which can help during detail work or repeated edging. The main catch is that it is sold without a battery or charger, so it makes less sense as a first cordless tool. Its three functions add flexibility, but buyers seeking an included-battery kit should look to the RAXONE or WORX instead.
Pros:- Three functions cover weed removal, string trimming, and edging.
- 14-inch cutting path is wider than the 12-inch RAXONE and WORX WG170.
- Four-pound weight suits light, detailed yard work.
- Detachable wheels support both guided and handheld use.
Cons:- Battery and charger are not included.
- Requires a compatible DeWalt 20V MAX battery.
- The supplied information does not specify runtime or charging time.
Best for: Homeowners with DeWalt 20V MAX batteries who want a lightweight tool for trimming, weed removal, and edging.
Not ideal for: First-time cordless-tool buyers who need a battery and charger included, or anyone without a compatible DeWalt 20V MAX battery.
- Battery compatibility:DeWalt 20V MAX lithium-ion
- Battery and charger:Not included
- Cutting path:14 inches
- Functions:Weed remover, string trimmer, and lawn edger
- Weight:4 lbs
- Motor speed:20,000 rpm
- Wheels:Detachable
- Included line spools:8
Our verdict“Choose the Lemolifys if you own a compatible DeWalt battery and value low weight and three-in-one versatility over a complete starter kit.”
RAXONE 21V Cordless String Trimmer and Edger with Two 2.5Ah Batteries
The RAXONE puts adjustability and a ready-to-use kit ahead of a wide cutting path. Its head rotates 90 degrees for edging and tilts from 0 to 90 degrees to reach slopes and corners, giving it more angle flexibility than the fixed-use details provided for the WORX WG170. Automatic line feed also removes the need to tap the head to advance line. Two included 2.5Ah batteries and a fast charger make this a more complete purchase than the tool-only Lemolifys, though its 12-inch width covers less ground than the Lemolifys’ 14-inch path or the EGO’s 16-inch swath. The listing gives conflicting weights—6.2 pounds in the specifications and 5.27 pounds in the description—so I would not choose it on weight claims alone.
Pros:- Rotating and tilting head adapts to edging, slopes, and corners.
- Automatic line feed avoids manual tapping.
- Includes two 2.5Ah batteries and a fast charger.
- 12-inch cutting width handles ordinary residential trimming.
Cons:- Listed weight is inconsistent: 6.2 pounds in the specifications versus 5.27 pounds in the description.
- Its 12-inch cutting width is narrower than the Lemolifys and EGO options.
- The supplied information does not state runtime or charging time.
Best for: Homeowners who edge along varied slopes and corners and want two batteries and a charger included.
Not ideal for: Buyers prioritizing a wide cutting path, a clearly stated weight, or a battery system they already own.
- Voltage:21V
- Motor speed:9,500 RPM
- Cutting width:12 inches
- Line feed:Automatic
- Head adjustment:Rotates 90°; tilts 0–90°
- Batteries:2 × 2.5Ah included
- Charger:Fast charger included
- Weight:6.2 pounds in specifications; description also states 5.27 pounds
Our verdict“Pick the RAXONE if adjustable head angles and an included two-battery kit matter more than a wider cut or unambiguous weight information.”
EGO POWER+ 16-Inch Cordless String Trimmer with 4.0Ah Battery and Charger, ST1623T
The EGO stands apart when the priority is covering more lawn with fewer passes: its 16-inch cutting width is the broadest among these five, exceeding the 14-inch Lemolifys and the 12-inch RAXONE and WORX. LINE IQ automatic feeding maintains the swath, while POWERLOAD simplifies reloading when the line runs out. A telescopic carbon-fiber shaft can be adjusted for reach and posture, and the included 4.0Ah battery is rated for up to 60 minutes of runtime. Compared with the lighter Goodjob, though, the EGO weighs 7.5 pounds and is much longer when assembled, which may make it less convenient for compact storage or frequent short jobs. Its larger coverage and feature set suit bigger trimming areas, but runtime remains limited by a single charge.
Pros:- 16-inch cutting width covers more ground per pass than the other products in this batch.
- LINE IQ automatically feeds line to maintain the cutting swath.
- POWERLOAD simplifies line reloading.
- Includes a 4.0Ah battery and charger, with up to 60 minutes of stated runtime.
Cons:- At 7.5 pounds, it is heavier than the Lemolifys and Goodjob.
- The listed 72.4-inch length may be awkward to store.
- Runtime is rated for up to 60 minutes per charge.
Best for: Homeowners with larger trimming areas who want a wide cutting swath, automatic line management, and an adjustable shaft.
Not ideal for: People who prioritize a very lightweight trimmer, compact storage, or uninterrupted work beyond the stated per-charge runtime.
- Cutting width:16 inches
- Battery:4.0Ah lithium-ion, included
- Battery compatibility:EGO 56V ARC Lithium
- Runtime:Up to 60 minutes
- Charging time:55 minutes
- Motor:Brushless
- Shaft:Telescopic carbon fiber
- Weight:7.5 pounds
- Warranty:5 years for tool; 3 years for battery
Our verdict“Choose the EGO if your priority is a wide cutting path and easier line management, and its weight and storage length suit your space.”
WORX 20V 12-Inch 3-in-1 Cordless String Trimmer, Lawn Edger, and Mini Mower (WG170)
The WORX WG170 is the most lawn-oriented multitasker in this group: it converts among a string trimmer, edger, and mini mower, a useful combination for small or medium yards with borders and tight patches. Its automatic command feed advances line without a manual tap, and the two included 2.0Ah batteries let you swap packs rather than stop when one runs down. Compared with the RAXONE, the WG170 adds a mini-mower function; compared with the much wider EGO, its 12-inch cut means more passes across open ground. The lighter 5.5-pound design and adjustable handles favor manageable detail work, but the listed five-hour charging time can leave less flexibility between sessions. I would skip it for large yards or demanding, heavy-duty cutting.
Pros:- Three functions include a mini mower, unlike the two-function RAXONE.
- Automatic command feed advances line without stopping to tap.
- Two 2.0Ah batteries are included for swapping during a job.
- At 5.5 pounds, it is lighter than the RAXONE’s listed weight.
Cons:- The 12-inch cutting width requires more passes than the EGO’s 16-inch swath.
- Listed charging time is five hours.
- Plastic construction may be less durable than heavy-duty metal alternatives.
Best for: Owners of small to medium lawns who want one tool for trimming, edging, and tidying small patches.
Not ideal for: People with large lawns, heavy vegetation, or a need for short battery recharge intervals.
- Voltage:20V
- Cutting width:12 inches
- Motor speed:7,600 RPM
- Functions:String trimmer, lawn edger, and mini mower
- Batteries:2 × 2.0Ah lithium-ion included
- Charging time:5 hours
- Weight:5.5 lbs
- Dimensions:45.1 in L × 37.4 in W
Our verdict“Pick the WORX WG170 for a small or medium lawn where three-in-one flexibility matters more than fast charging or wide-area coverage.”
Goodjob 20V Cordless String Trimmer and Weed Eater with 2 Batteries
At 3.5 pounds, the Goodjob is the easiest choice here for buyers who want to minimize arm fatigue during routine trimming. Its 12-inch cutting width and three-way setup for trimming, edging, and weed cutting give it more flexibility than a basic trimmer, while two included 2.0Ah batteries provide a spare for swapping. Against the heavier RAXONE, the Goodjob favors low weight over a highly adjustable head; against the wider EGO, it is better suited to modest yard jobs than broad coverage. The stated 40–60 minutes of runtime varies with grass thickness and workload, and its 20V platform is positioned for light-to-medium tasks rather than demanding cutting. Plastic construction is another reason to keep expectations focused on residential use.
Pros:- 3.5-pound weight is the lightest among the battery-included trimmers in this batch.
- Three-in-one design supports trimming, edging, and weed cutting.
- Two 2.0Ah batteries are included for swapping.
- Listed noise level is under 75 dB.
Cons:- Runtime varies from 40 to 60 minutes depending on workload.
- 20V power is suited to light-to-medium tasks rather than demanding cutting.
- Plastic construction may be less durable than commercial-grade metal trimmers.
Best for: People who want a very light, complete cordless kit for routine trimming and edging around a small or medium yard.
Not ideal for: Buyers tackling thick, demanding vegetation, seeking commercial-grade durability, or needing a wider cut than 12 inches.
- Power source:20V lithium-ion battery
- Weight:3.5 lbs
- Cutting width:12 inches
- Batteries:2 × 2.0Ah included
- Runtime:40–60 minutes
- Functions:String trimming, edging, and weed cutting
- Noise level:< 75 dB
- Model:GB-DST26A-2MG
Our verdict“Choose the Goodjob for light residential upkeep if low weight and two included batteries matter more than heavy-duty capability or a broad cutting path.”
Makita XRU23Z 18V LXT Lithium-Ion Brushless Cordless 13″ String Trimmer (Tool Only)
The Makita XRU23Z is a strong fit for yard work where motor durability and control matter more than a kit-in-the-box setup. Its brushless motor reaches 6,000 RPM, while the variable-speed trigger and high/low setting let me temper output for lighter trimming or use more power on tougher growth. Compared with the WORX WG163, it offers a wider 13-inch cut and a brushless motor, but lacks the WORX’s included batteries and quick conversion between trimming and edging. Makita’s XPT water- and dust-resistant design adds reassurance for demanding outdoor conditions, and the rapid-load bump-feed head simplifies line changes. The tradeoff is practical: battery and charger are separate, and the 9.2-pound tool may tire users during long sessions. Its stated runtime of up to an hour depends on using a 4.0Ah battery.
Pros:- Brushless motor with variable-speed trigger and high/low power settings
- XPT protection helps resist water and dust
- Rapid-load bump-feed head simplifies line replacement
- 13-inch cutting width suits routine trimming
Cons:- Battery and charger are sold separately
- At 9.2 pounds, it may feel heavy during extended use
- Up to one hour of runtime is specified with a 4.0Ah battery, which may not cover large yards
Best for: Makita 18V LXT owners who want a durable brushless trimmer for regular, controlled yard maintenance.
Not ideal for: First-time cordless buyers or people with large properties who need batteries included and longer uninterrupted runtime.
- Model:XRU23Z
- Power source:18V LXT lithium-ion battery, sold separately
- Motor:Brushless
- Cutting width:13 inches
- Maximum speed:6,000 RPM
- Runtime:Up to 1 hour with a 4.0Ah battery
- Weight:9.2 pounds
- Protection:Extreme Protection Technology (XPT), designed to resist water and dust
Our verdict“Choose the Makita if you already own compatible batteries and value a brushless, weather-resistant tool over an all-in-one kit.”
WORX WG163 20V 12-Inch 2-in-1 Cordless String Trimmer and Lawn Edger
The WORX WG163 is the most ready-to-work choice here for buyers who want both trimming and edging without sourcing a battery separately. It includes two 20V batteries and a charger, and its head converts between jobs while tilting up to 90 degrees for edging along uneven ground. Rubberized guide wheels help keep an edge steady, and the spacer guard can help protect plants and hardscape. Compared with the BLACK+DECKER LST136, the WORX supplies a second battery and more edging-oriented guidance, while the BLACK+DECKER offers a wider 13-inch cut and a power/runtime dial. The WG163’s 12-inch swath means more passes across open areas, and its push-button line feed is a different approach from automatic-feed models. It makes most sense for smaller yards with mixed lawn edges, not demanding brush or broad, uninterrupted trimming.
Pros:- Includes two 20V lithium-ion batteries and a charger
- Converts between string trimming and lawn edging
- Tilting head and rubberized guide wheels aid edging on uneven ground
- Adjustable spacer guard helps protect plants and landscape features
Cons:- 12-inch cutting width requires more passes over wider areas
- Push-button line feed requires manual activation
- Battery operation still means work time depends on charging and battery capacity
Best for: Homeowners with small or medium yards who want an included battery kit and guided edging along paths and garden beds.
Not ideal for: People tackling large open areas or thick growth who need a wider cutting path and a trimmer designed for heavier work.
- Power source:20V battery
- Batteries included:Two lithium-ion batteries
- Cutting width:12 inches
- No-load speed:7,600 RPM
- Weight:5.5 pounds
- Line diameter:0.065 inches
- Functions:String trimmer and lawn edger
- Included accessories:20V charger, trimmer spool, support wheels, and safety guard
Our verdict“Pick the WORX WG163 for a well-equipped small-yard kit where edging control and a spare battery matter more than cutting width.”
BLACK+DECKER 40V MAX Cordless String Trimmer and Edger, 13-Inch, with Battery and Charger (LST136)
The BLACK+DECKER LST136 stands apart for giving me a way to choose between cutting performance and longer runtime rather than locking the tool into one pace. Its PowerCommand dial adjusts that balance, and the 40V battery powers a 13-inch trimmer that converts to an edger. Automatic line feed also removes the need to bump the head to advance line. Compared with the WORX WG163, the LST136 has a wider cutting path and power/runtime selection, but the WORX includes two batteries and guide wheels for edging. The included 2.0Ah battery is a limiting factor for extended jobs, and its charger can take up to two hours to restore full power. This is a more capable-feeling kit for variable yard tasks, though it is not the pick for buyers who prioritize spare-battery capacity or a lighter tool.
Pros:- PowerCommand dial lets users favor power or runtime
- 13-inch cutting width covers more ground than 12-inch alternatives
- Converts between trimming and edging
- Includes a 40V battery and fast charger
Cons:- Included battery is 2.0Ah
- Charger may take up to two hours to restore full battery power
- Heavier than the 5.5-pound WORX WG163
Best for: Homeowners with mixed trimming and edging needs who want to adjust power use and receive a battery and fast charger in the kit.
Not ideal for: People with large yards who need extended sessions from the included battery or shoppers seeking a particularly light trimmer.
- Model:LST136
- Battery:40V MAX, 2.0Ah lithium-ion
- Cutting width:13 inches
- Maximum speed:8,500 RPM
- Weight:7.8 pounds
- Functions:String trimmer and edger
- Line feed:Automatic feed spool
- Warranty:3-year limited warranty
Our verdict“Choose the LST136 if adjustable power and a wider cut matter more than the spare battery and edging wheels offered by the WORX WG163.”
BLACK+DECKER 20V MAX Cordless String Trimmer and Edger, 12-Inch, with Battery and Charger (LST300)
At 5.7 pounds, the BLACK+DECKER LST300 puts easy handling ahead of coverage, making it a sensible choice for brief trimming sessions around a smaller yard. Its adjustable height and handle help tailor the fit, while the automatic feed spool advances line without bumping. It also converts into a wheeled edger, so one tool can tidy grass along a walk or bed. Compared with the BLACK+DECKER LST136, the LST300 is lighter and runs on a 20V platform, but gives up the 40V model’s 13-inch cutting width and PowerCommand setting. The included 2.0Ah battery helps get a buyer started, though its capacity may constrain longer jobs. The 12-inch swath also means extra passes across wide areas. I’d favor it for manageable lawns and easy handling, not long stretches of heavy trimming.
Pros:- Light 5.7-pound design is easier to maneuver
- Adjustable handle and height help tailor fit
- Converts to a wheeled edger
- Automatic feed spool advances line without bumping
Cons:- 12-inch cutting width takes more passes over larger areas
- Included battery has a 2.0Ah capacity
- Less suited to extended heavy-duty trimming than the 40V BLACK+DECKER LST136
Best for: People with compact lawns who want a lightweight trimmer-edger with an included battery and automatic line feed.
Not ideal for: Owners of large yards or overgrown areas who need a wider cutting path or longer runs from a single battery.
- Model:LST300
- Battery:20V MAX, 2.0Ah lithium-ion, one included
- Cutting width:12 inches
- Speed:6,200 RPM
- Weight:5.7 pounds
- Functions:String trimmer and wheeled edger
- Line feed:Automatic Feed Spool (AFS)
- Warranty:2-year limited warranty
Our verdict“The LST300 is a good fit for smaller yards where light handling and simple edging outweigh cutting width and battery capacity.”
DEWALT 20V MAX* XR String Trimmer, 14-Inch, Tool Only (DCST922B)
The DEWALT DCST922B combines the widest cutting swath in this group with a folding hinge that shortens the tool by 40% for storage or transport. That pairing suits buyers who have room for a 14-inch trimmer at work but limited space in a garage or vehicle afterward. Its variable-speed trigger and Hi/Lo switch let me manage output and runtime, while the QuickLoad Spool speeds line replacement. Compared with the Makita XRU23Z, it cuts a wider path and folds for storage, while the Makita offers a brushless motor and water- and dust-resistant XPT design. The DEWALT is sold as a tool only, weighs 9.2 pounds, and its 0.080-inch line may be less suited to very thick brush. It is a purposeful choice for DEWALT battery owners who value packability over an included kit.
Pros:- 14-inch cutting width covers a larger swath than the 12- and 13-inch alternatives here
- Folding hinge reduces length by 40% for storage and transport
- Variable-speed trigger and Hi/Lo control help balance output and runtime
- QuickLoad Spool simplifies line replacement
Cons:- Battery and charger are sold separately
- At 9.2 pounds, it may be tiring during extended use
- Limited to 0.080-inch line, which may struggle with very thick brush
Best for: DEWALT 20V MAX battery owners who need a wide-cutting trimmer that folds down for compact storage or transport.
Not ideal for: Buyers without compatible batteries, users who prioritize low weight, or anyone regularly cutting very thick brush.
- Model:DCST922B
- Power source:20V MAX battery, sold separately
- Cutting width:14 inches
- Speed:6,000 RPM
- Weight:9.2 pounds
- Line size:0.080 inches
- Storage feature:Folding hinge reduces length by 40%
- Warranty:1 year
Our verdict“Choose the DEWALT if you already own its battery platform and want a wide-cutting trimmer that stores more compactly than the Makita XRU23Z.”
How We Picked
I ranked these trimmers around the tasks that make a cordless model a practical yard tool: cutting width, stated battery setup, included charger, edging or multi-function features, and fit with an existing battery platform. A wider path can cover open ground faster, but it does not automatically make a trimmer the best choice for narrow beds or detailed work. I also separated ready-to-use kits from tool-only models, since the latter can be a sensible choice for platform owners but a less straightforward purchase for everyone else.
The order reflects how broadly useful each option appears for the buyer it serves, not a claim that one specification predicts real-world runtime or cutting strength. Models with clear kit contents and useful capacity sit higher for general yard work; specialized or less clearly differentiated options rank lower unless their battery bundle, compact format, or platform compatibility offers a distinct advantage. I also weighed meaningful tradeoffs: a larger cutting path can demand more from a battery, extra functions may add complexity, and battery compatibility should be checked before purchase.
Factors to Consider When Choosing Best Battery Powered String Trimmers
My picks show that choosing a cordless trimmer is as much about the job and battery system as it is about the tool. Before comparing feature lists, estimate how much trimming you do, what batteries you already own, and whether you need clean edges or just grass control. These factors can help narrow the field without assuming that the widest or most feature-packed model is right for every yard.
Match Cutting Width to the Shape of Your Yard
A wider cutting path covers more ground with each pass, which can reduce time along long fence lines and open lawn edges. The lineup runs from 12-inch options to EGO’s 16-inch model, but the largest path is not automatically the easiest to handle around trees, posts, and narrow planting beds. Think about the tightest spaces you trim, not just the broadest patch of grass. A smaller path can offer better control where edging and detail work take priority. Do not assume a stated cutting width tells you how quickly a trimmer will clear tough growth; battery capacity, line, and vegetation also affect the job. Choose a width that fits your yard layout, then check the tool’s battery arrangement and handling details.
Check Battery Compatibility Before Comparing Kit Contents
A battery included in the box is convenient if you are starting fresh, while a tool-only trimmer can be a better fit if you already own compatible packs. Compatibility is not universal just because two products show the same voltage or a familiar brand name. Confirm the exact battery platform and model support before you buy, especially for third-party tools designed around another company’s packs. Also check whether the kit includes a charger, not only a battery. A second battery can be helpful when one pack cannot cover your whole trimming session, but it does not tell you how long either pack will run. Compare the full setup you need—tool, battery, and charger—rather than judging the trimmer by its listing name alone.
Treat Runtime as a Job-Matching Question
Runtime depends on more than the battery’s stated capacity: thick grass, frequent edging, cutting width, and trigger use can all affect how quickly a pack is depleted. A larger battery may support longer work between charges, but it can also add weight to a handheld tool. If your routine involves short touch-ups, a compact kit may be easier to manage than carrying extra capacity you rarely use. For larger yards, a second compatible battery can keep work moving while the first charges. Avoid using battery voltage by itself as a shortcut for predicting runtime or cutting performance. Match the battery setup to the length and intensity of your usual sessions.
Decide Whether You Need Edging or Multi-Function Features
A rotating head or 2-in-1 design can simplify switching from trimming grass to cutting a clean boundary along a path. A mini-mower function, as offered by the WORX WG170, targets a different need: small patches where a full-size mower is awkward. Those added modes may be useful in a compact or detailed yard, but they are not a substitute for a mower on a large lawn. More functions can also mean more steps when changing modes, so think about how often you will use them. If you mainly trim around obstacles, a simpler design may be easier to handle. Buy extra versatility for jobs you actually have, not just because a feature list is longer.
Account for Handling, Balance, and Reach
Trimming involves repeated sweeping and holding the tool away from your body, so balance can matter as much as raw cutting width. Battery placement, shaft design, and handle adjustment can change how manageable a trimmer feels during a longer session. If possible, check the tool’s weight with its battery installed rather than relying on a bare-tool figure. Look for adjustments that help you keep a comfortable grip while edging or reaching along a fence. A powerful tool that feels tiring may slow a small-yard job more than a compact model would. Buyers with frequent or extended trimming should give handling features real weight in the decision.
Look Beyond the Initial Tool to Line and Maintenance
String trimmers need replacement line, and the way a model feeds or reloads line can affect routine upkeep. Before choosing, check what line type and diameter the manufacturer specifies and whether replacement spools or compatible line are easy for you to source. Automatic feed can reduce manual adjustments, while bump-feed designs require a different habit and may suit some users better. More complicated heads can save time when they work well, but can be less appealing if you prefer a simple reload process. Keep the manual and compatible replacement parts in mind when comparing models. A trimmer that fits your maintenance preferences is more likely to stay ready for regular yard work.
Frequently Asked Questions
Should I buy a tool-only trimmer or a kit with a battery and charger?
A tool-only model can be a sensible choice if you already own batteries and a charger from the exact compatible platform. The Makita XRU23Z and DEWALT DCST922B are examples in this roundup, so they are less complete as standalone purchases. If you are starting without compatible batteries, compare the cost and availability of the full system before choosing a bare tool. Check the manufacturer’s compatibility information rather than relying on voltage alone. A kit is usually simpler for a first cordless trimmer, while platform owners can avoid duplicating gear by buying tool-only.
Is a 16-inch cutting path always better than a 12-inch one?
No. A wider path can cover open grass more quickly, but a narrower trimmer may be easier to control around flower beds, trees, and tight corners. This roundup includes 12-inch WORX models suited to maneuverable trimming as well as EGO options with wider paths for broader coverage. Yard shape matters: a large, open boundary favors reach, while a small, detailed yard may reward precision. Battery capacity and tool handling also affect whether a wider path is useful for your routine. Choose based on the areas you trim most often, not the largest number in the specifications.
Do two included batteries mean a trimmer will run longer than a single-battery kit?
Two batteries can give you another charged pack to use, which may reduce interruptions if one runs out during a job. They do not establish how long each battery will run, and packs with different capacities are not directly comparable by count alone. Workload, vegetation, cutting width, and trigger use all affect runtime. Check whether both batteries and a charger are included, and find out whether the charger can replenish a pack while you work with the other. For a large yard, battery capacity and charging time matter more than the number of packs on the box.
Can a string trimmer with an edging or mini-mower mode replace a lawn mower?
Not for most full lawns. Edging mode is meant to clean up boundaries, while a mini-mower function such as the one on the WORX WG170 is aimed at small patches or awkward spots. A dedicated mower covers broad turf more efficiently and is a better fit for routine lawn cutting. Multi-function trimmers can reduce the number of tools needed for small yards or detail work, but they have limited reach and coverage compared with a mower. Buy one for the specific small-area jobs you expect it to handle, not as a replacement for equipment sized to your whole lawn.
What should I check before buying a trimmer for an existing battery system?
Confirm the exact battery family, voltage, and model compatibility listed by the trimmer manufacturer. Similar-looking packs or matching voltage labels do not prove that batteries and chargers will work across products. Check whether the tool requires a particular pack type and whether your current charger supports it. Also account for how much capacity your other tools may need during the same work period. A tool-only model is most useful when your existing batteries genuinely fit and you have enough packs to cover your yard tasks.
Conclusion
For most buyers, I recommend the EGO Power+ ST1511T as the best overall: its 15-inch path and included battery and charger make it a balanced starting point. For a wider cut and a 4.0Ah kit, the EGO ST1623T is my best premium pick, particularly for buyers with more ground to cover. The WORX WG163 is my best value-style choice for shoppers who want a compact 2-in-1 trimming and edging setup, while the BLACK+DECKER LST300 is my beginner-friendly pick for a straightforward kit with battery and charger included. If you already own compatible batteries, consider the Makita XRU23Z or DEWALT DCST922B rather than paying for a battery system you do not need; for small patches and extra lawn-detail versatility, the WORX WG170 is the standout specific-use option. Match the trimmer to your yard size, battery platform, and most frequent task, and the right choice becomes much clearer.
