Our Picks at a Glance
How To Choose The Best Battery Powered String Trimmer
You want a cordless weed eater that finishes your yard without dying mid-trim. That depends on three numbers: battery runtime, cutting width, and motor power for thick weeds. Get those right, and you won’t be back shopping next season.
Runtime vs. Yard Size
Look at the battery average life in minutes and compare it honestly against how long your trimming takes. A model with 30 minutes of run time will vanish on a large property, while one rated at 45 minutes or more can usually finish a typical suburban lot on a single charge. If you have a big yard, you will want a trimmer that takes a backup battery or one with a longer-rated runtime.
Cutting Width and Power
The cutting swath in inches tells you how many passes you will make. A 12-inch head takes more sweeps to clear a fence line than a 16-inch head. Pair the wider head with a brushless motor for the tough stuff. A brushless motor usually means more torque, less vibration, and a longer tool life than a standard brushed motor.
Feed Systems and Ergonomics
The way new string comes out matters more than you think. Bump-feed heads need a tap on the ground, while button-feed or auto-feed systems advance the line for you. Also check the weight and whether the shaft adjusts to your height. A trimmer that is heavy in the back can wear out your arms on a hilly yard, no matter how powerful it is.

In‑Depth Reviews
1. EGO MHC1603 Multi-Head Combo Kit
Our pick — over 4.5★ from 950+ verified ratings; the strongest balance of quality and price.
The gas-switching powerhouse that brings edging and trimming into one kit.
This EGO kit is the one that convinces people to park their gas Stihl for good. The 16-inch carbon fiber trimmer attachment pairs with a separate 8-inch edger attachment, both running off the same 56V power head — so you swap between trimming and crisp edge lines without any tools. The brushless motor delivers the kind of grunt that slices through months of overgrowth.
Runtime is the headline: up to 45 minutes on the included 4.0Ah battery with the trimmer, and up to 75 minutes when you switch to the edger on low. That is a full 50% longer than the Greenworks 24V’s 30-minute battery life, and the 16-inch swath beats that model’s 12-inch cut by a third. The POWERLOAD system lets you feed the line, push a button, and return to trimming in seconds.
The honest trade-off is weight. Buyers report the tool runs back-heavy with the battery mounted behind the motor, and the shoulder strap becomes essential for longer sessions. The crowd favorite line sums it up: the 5.0Ah battery lasts ~30 min, so buyers with large yards say to grab a backup or the 9.0Ah. Owners mention it is twice as quiet and faster than traditional gas tools, with zero emissions and instant start.
Why Owners Switch to This
- 16-inch cutting width clears wide paths fast
- POWERLOAD auto-line feed ends bumping the head
- Edger attachment creates crisp 3-inch deep edges
- Lifetime warranty on carbon fiber shafts
Where It Gets Heavy
- Back-heavy balance needs the shoulder strap
- 45-minute runtime means a backup battery for big yards
Best for: anyone replacing a gas trimmer who wants tool-free switching between trimming and edging.
Look elsewhere if: you need to trim several acres — bring a second battery or the higher-capacity 9.0Ah pack.
2. Greenworks 24V 12 in Cordless String Trimmer
A featherweight that keeps beginners from getting worn out mid-trim.
At just 6 pounds with a cushioned grip, this Greenworks is designed for people who find gas trimmers exhausting. The telescoping aluminum shaft adjusts to fit users from 4’8” to 6’5”, and the 90° rotating head pivots so you can edge around tree roots and sloped terrain without contorting your wrists. It converts from trimmer to edger with one button — no tools needed.
The 12-inch cutting width is more compact than most, and the 30-minute battery life is entry-level. Compare that to the EGO’s 45 minutes and 16-inch swath, and you see the gap in capability. What this model has is simplicity: push-button start, a.065” single-line auto-feed head, and a 75 dB noise level that is quieter than a vacuum and polite for early-morning HOA neighborhoods.
Here is the honest fit-note. The power draws praise — it chewed through 60 feet of overgrown edges in 10 minutes for one owner — and the adjustability gets credit for steep banks. The auto-feed feature also divides owners, with some calling it effective and others needing to take the head apart repeatedly.
The real trade-off: you get a light, adjustable, easy-start trimmer for a budget price, but treat the build gently and keep expectations modest on lifespan.
Reach for this if: you are new to trimming, have a small flat yard, and want the lightest option for your height.
Think twice if: you value durability above all — the feedback on long-term build quality is mixed.
3. VARSK 12 Inch Cordless Weed Wacker
Two batteries and six spare spools so you can keep going without shopping trips.
The VARSK arrives with everything to keep you trimming for a long time: two 2.0Ah lithium batteries, a charger, and six replacement spools. The dual-battery setup delivers 30+ minutes of runtime, and the 8700RPM motor powers through regular lawn, garden, and yard work. At 5.3 lbs, it is light enough for one-hand maneuvering.
Converting from trimming to edging takes a simple 90° rotation of the aluminum tube, and the 80° pivoting cutting head reaches into hard-to-access spots. An integrated stabilizer wheel aids steady edging. The package includes three times more line life per spool, stretching time between changes.
The weight is the thing owners praise most, and ease of use is the second most-mentioned positive. Performance feedback is honestly split: some call it a no-brainer that edges grass and clears weeds from cracks effectively, while others say edging a single foot takes multiple passes for mediocre results. If you have aggressive overgrowth, expect to double-pass around raised beds. For standard tidy-up work on a small yard, this is a capable, affordable pick.
Who it suits: budget-conscious owners who want spare batteries and spools included from day one.
The caution: heavies and thick tangles may test its limits — keep expectations at general trimming, not demolition.
Best for: small-to-medium lawns where light weight and included spares outweigh peak power needs.
Not ideal if: you regularly battle thick, tall weeds that need serious torque.
4. CRAFTSMAN V20 String Trimmer and Edger Kit
A trimmer that outlasts your whole trimming session on one charge.
Runtime is the story here: up to 63 minutes from the included 4.0Ah V20 battery, which is longer than most competitors and enough to finish a typical suburban trimming job without swapping packs. The 13-inch cutting swath clears wide ground per pass, and the Turn-To-Edge functionality converts it into a lawn edger with a single motion. A two-speed selector lets you prioritize runtime or raw power.
It is also one of the easier trimmers to live with daily. The handle adjusts to your height, and owners consistently note the lightweight feel and easy assembly — one owner installed it with just a Phillips screwdriver in minutes. The power gets credit for slicing through thick grass, with quality being the aspect buyers mention most positively.
The battery drains faster above level-one, so owners recommend an extra battery for bigger projects. Durability reads as solid for the price, though a few describe it as more lite duty than heavy commercial work. If your yard is medium-sized and you want a single charge to carry you through, this is a smart budget-friendly pick.
The Ceiling
- 63-minute runtime tops the budget tier
- 13-inch swath reduces passes
- Height-adjustable handle for comfort
- Converts to edger without tools
The Limit
- Battery drains fast above level one
- Best for medium yards, not acres
The pick for: homeowners who want maximum runtime per dollar and an easy-to-live-with tool.
The caveat: if you always need max power, carry a spare battery.
5. BLACK+DECKER 20V MAX Cordless String Trimmer and Edger
The crowd-favorite that has been quietly trimming lawns for eight years straight.
This is the trimmer that refuses to die. Customers note it is still working and looking new after eight years of normal use, which is remarkable for a cordless tool. The EASYFEED system advances your line with the push of a button — no bumping required — and the PowerDrive transmission increases torque for more cutting power at the string. A two-speed control lets you boost power or extend runtime.
It ships with two batteries for double the runtime, plus a charger and a spare spool. The 12-inch cutting width is standard for home use, and the tool converts from trimmer to a wheeled edger easily. The adjustable height and handle with a premium soft grip improve comfort during longer sessions. Weighing 5.3 pounds, owners say you can maneuver it with one hand.
The thing everyone raves about is the functionality — it is the most-mentioned positive by a wide margin, and lightweight design is the second most-praised trait. Battery life is the messy middle: the stock 20V batteries give roughly 10 minutes each in real use, though owners note that an aftermarket 6Ah pack extends that to about an hour. Durability is generally good, but the trigger mechanism can wear out after years of use.
The smart buy: the GreenWorks 40V 13-Inch—a proven, widely-reviewed trimmer that handles typical home lawns with a 40-volt battery and a 13-inch cutting path.
The honest gap: stock batteries are small, so plan to buy a higher-capacity pack or carry both included ones.
Grab it if: you want a proven, lightweight trimmer backed by a huge owner base.
skip it if: you need one battery to cover a large acreage — this favors smaller jobs.
6. Greenworks 60V 16 in Cordless String Trimmer
Serious voltage and a 16-inch swath for the overgrowth your neighbors avoid.
This Greenworks brings a 60V brushless motor spinning at 6000 RPM — performance owners say is equivalent to a 26cc gas trimmer. It tackles 1-inch thick blackberry vines and stubborn kudzu, while the dual-line system chews through ditch weeds and pine saplings. The 16-inch professional swath clears a two-mile fence line in one go, making it a genuine acreage tool.
Runtime is strong at up to 65 minutes on the 2.5Ah battery, and the Spin-to-Load head lets you reload.095” line in about 10 seconds without manual winding — a real time-saver versus bump-feed heads. It weighs 11.2 lbs with the battery, but the 360° rotating handle reduces wrist strain and keeps the balance feeling manageable. A 4-year full warranty covers the tool and battery, even for accidental rock damage.
Quality is what wins people over here, with power the close second. Owners describe it as easily outperforming other brands and note the 60V battery lasts dramatically longer than lower-voltage competitors. The battery-life feedback is honestly split — some report at least 45 minutes, others say 15 per charge. The recurring gripe is the guard, which some find too small and poorly angled, leaving you dusted with debris.
The Muscle
- 6000 RPM brushless motor matches gas power
- 65-minute runtime for larger jobs
- Spin-to-Load head reloads line in seconds
- 16-inch dual-line cutting swath
The Annoyance
- Small angled guard lets debris fly
- Battery reports vary widely by user
The pick for: owners with thick weeds and larger lots who want gas-level power without the fumes.
The fit note: if you are picky about debris spray, budget for a bigger guard.
7. SKIL PWR CORE 40 Brushless 40V Multi-Head System
The attachment-ready system that grows with your yard-tool collection.
The headline here is versatility: the 40V power head is designed to work with SKIL 40V attachments, so the same motor can power other tools down the road. The kit includes the string trimmer head with a 16-inch cutting swath for tall grass and thick weeds, plus the PWR CORE 40 4.0Ah lithium battery and an Auto PWR JUMP Charger. The digital brushless motor runs cooler and longer than standard motors.
A dual-line bump feed lets you release fresh line by tapping the head on the ground, while the Twist Load Head makes reloading simple — insert the line and twist. The two-speed selector lets you choose between maximum power or longer runtime, and the adjustable auxiliary grip gives added control over where you point it. Owners call it powerful and sturdy, crediting it with taking down hefty, stubborn weeds.
Effectiveness is the thing owners praise most, with performance close behind. Battery life gets consistently positive feedback at around 45 minutes per charge, though a few owners note that the included 4.0Ah battery runs short for larger lots and have upgraded to a bigger pack. Weight is the mixed note: some find it fine, others call it heavy. If you plan to expand a SKIL cordless lineup, this is a smart starting point.
The system play: buy one power head and add attachments instead of whole new tools.
The consideration: budget for a larger battery if your lot is big.
Best for: owners who want one motor to do multiple yard jobs via attachments.
Pass if: you need a light tool — this one sits heavier than some rivals.
8. EGO POWER+ String Trimmer ST1620T
The self-feeding trimmer that magically keeps your line at perfect length.
The defining feature is patented LINE IQ Technology — an auto-feed system that extends the line automatically, no bumping, no pushing buttons. It pairs with POWERLOAD, so you feed a spool of line, push a button, and the tool winds it for you. Owners are genuinely surprised it works, with one calling the automatic line extending amazing and crediting it with beating a gas weed eater on an acre of overgrown land.
The carbon fiber shaft is telescopic, quickly adjusting to fit your height for comfort, and it is backed by a lifetime warranty when registered within 90 days of purchase. It runs a continuous 16-inch cutting swath with a professional-grade dual-line spiral-twist 0.095 in. line. The high-efficiency brushless motor and digital 2-speed selector round out a pro-grade package. Recommended for use with the EGO 4.0Ah 56V ARC Lithium battery for up to 60 minutes of cut time.
Performance is the aspect owners mention most by a large margin, with ease of use the second-most praised. One owner on a 12-acre farmette reports two summers with no complaints, calling it the best weed eater ever and noting it winds the line itself. Weight is genuinely divided — some find it incredibly light thanks to the carbon fiber rod, others call it heavy. Note that this is a bare tool: the battery and charger are not included, so it only makes sense if you already own EGO 56V batteries.
The Magic
- LINE IQ auto-feed ends bumping forever
- POWERLOAD winds new line automatically
- 60-minute runtime with 4.0Ah battery
- Telescopic carbon shaft fits any height
The Catch
- Battery and charger sold separately
- Weight feedback is genuinely split
The pick for: EGO battery owners who want the smartest auto-feed system on the market.
Not for: first-time cordless buyers — you need EGO batteries to run it.
9. Makita XRU23SM1 18V LXT Brushless Cordless 13″ String Trimmer
The builder-grade trimmer that slides right into your existing Makita battery lineup.
If you already own Makita 18V LXT tools, this trimmer is a no-brainer because it runs on the same battery platform you already have. The brushless motor spins up to 6000 RPM and delivers up to one hour of run time on the included 4.0Ah battery. A high/low button manages power versus runtime, and a variable speed trigger gives you precise control over cutting speed — useful when you need a gentle touch near flower beds.
Owners call it lightweight, comfortable, and surprisingly powerful, with one noting a 4.0Ah battery was still at 50 percent after 40 minutes on an acre. The 15-inch cutting width is a nice middle ground between compact and wide. It handles both tall weeds and regular grass, and the easy-to-exchange string cartridge simplifies reloads. It even handles thicker.080 line, per one owner.
Functionality is the most-mentioned positive, with power and lightweight design close behind. The battery-life feedback is the classic split — some say it doesn’t use much power, others report it lasting only 15 minutes. One owner notes it struggles with crabgrass clumps and the positioning can feel a little unwieldy. If you live inside the Makita ecosystem, the versatility makes this a smart add; if not, you are paying for a battery system you do not yet own.
The ecosystem play: one battery style powers your whole shed, from drill to chainsaw to trimmer.
The honest caveat: the 13-inch head is smaller than the 16-inch rivals above.
Best for: Makita owners who want reliable trimming without a new battery system.
pass on it if: you are starting fresh — other brands offer wider cuts for similar money.
Understanding the Specs
Battery Runtime and Voltage
Runtime, listed in minutes, tells you how long the trimmer cuts on a single charge. Voltage (like 24V, 40V, or 56V) roughly tracks how much power the motor can draw. Higher voltage often means more torque for thick weeds, but runtime you actually feel in minutes. Pair the voltage with the battery capacity in Ah — a bigger Ah number usually means more cutting time before a recharge.
Cutting Width and Motor Type
Cutting width in inches is the path your string clears in one sweep. A wider 16-inch swath finishes fences and borders in fewer passes than a 12-inch head. Motor type matters too: brushless motors run cooler, vibrate less, and generally last longer than brushed motors. That efficiency often translates to longer runtime from the same battery.
