The first time you yank a gas trimmer cord twenty times without so much as a sputter, the appeal of a cordless line trimmer clicks instantly. No fuel mixing, no pull starts, no earplugs required. But with battery power comes a real question: will one charge actually finish your fence line, or will you be waiting around for a recharge halfway through? This guide cuts through the noise to find the cordless line trimmers that deliver enough runtime and cutting muscle for the real world — without the old gas-engine headaches.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you’re tidying up a small city lawn or wresting back a overgrown patch, the perfect cordless line trimmer needs to balance cutting power, battery stamina, and weight in a way that fits your actual yard.
Our Picks at a Glance
How To Choose The Best Cordless Line Trimmer
Picking the right cordless line trimmer depends on matching your specific yard size and vegetation type to the tool’s battery system, cutting width, and power delivery. Here are the key factors to weigh before you buy.
Battery Voltage and Capacity
Higher voltage (56V vs 20V) generally means more cutting power for thick weeds. But a higher amp-hour (Ah) rating on the battery directly controls how long you can trim. A 4.0Ah battery can last far longer than a 2.0Ah one, even at the same voltage.
Cutting Swath Width
The cutting swath is the width of the path your trimmer clears in one pass. Wider swaths (13 inches or more) let you finish larger areas faster. Narrower swaths (12 inches) are easier to maneuver around flower beds and fences.
Line Feed System
You’ll encounter three main types of line advancement. Bump-feed requires tapping the head on the ground. Auto-feed advances the line automatically when the motor starts or senses a need. Push-button feed lets you advance line with a finger press, giving you full control without stopping.
Motor Type
Brushed motors are common on budget models. Brushless motors are more efficient, run longer on a charge, and typically last longer. If you plan to use the trimmer heavily, the premium for brushless is worth it.

In‑Depth Reviews
1. OKIE HOME 12-Inch Cordless String Trimmer
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
At 5.27 pounds, this trimmer delivers surprising power for small to medium lawns.
You finish trimming without fighting the tool when you pick the OKIE HOME. At just 5.27 pounds and with a motor spinning at 9000 RPM (revolutions per minute — how fast the head turns), it slices through grass and light weeds quickly. The 12-inch cutting swath (the width it clears in one pass) lets you cover ground efficiently, while the 2-in-1 function lets you flip from trimming to edging along sidewalks without swapping attachments. Two included 2.0Ah (amp-hour — a measure of battery energy capacity) batteries each deliver 30–40 minutes of runtime, so you can swap and keep going when one runs low. The auto and manual line feed system advances the line 0.4–0.5 inches at startup or in convenient 0.4-inch increments with a button — no bumping required.
Functionality earns the most praise from owners, and the included extras — gloves, safety glasses, extra spools, and a wheel attachment for edging — get frequent shout-outs. Buyers report that the battery lasts through two uses for a small yard, making it a perfect match for postage-stamp lawns. The foldable, detachable shaft also stores flat, a real plus if your garage or shed is already packed. If you regularly face thick, tall weeds or a half-acre property, this trimmer’s 12-inch swath and 2.0Ah batteries mean you’ll be changing batteries more often than you’d like.
Lightweight maneuverable trimmer
- Remarkably lightweight at 5.27 lbs — easy for anyone to handle
- Two batteries included extend total runtime to 60–80 minutes
- Auto-feed line system keeps you trimming without constant adjustments
- Comes with useful accessories: gloves, goggles, extra spools, edging wheel
Battery runtime moderate
- Best suited for light to medium grass — not a heavy brush cutter
- Two 2.0Ah batteries mean shorter sessions per battery than larger-capacity packs
Reach for this if: you maintain a small to medium lawn and value lightweight ease, quick assembly, and a full accessory kit.
Think twice if: you face heavy, dense weeds or need to trim large areas without stopping to swap batteries.
2. FOKIKIP 12-Inch Cordless String Trimmer
Two speed settings let you switch between light trimming and tackling tougher weeds.
You get something rare at this price: two-speed control. Low speed is for daily trimming and fine work around flower beds; high speed gives you the RPMs to chew through dense or thick weeds. The 2-in-1 head switches between trimming and edging by stepping on a pedal and rotating the head 90 degrees — no tools needed. The automatic line feed system replenishes the line when needed and cuts off excess length, so you never bump the head to advance string. Up to 45 minutes of cordless runtime comes from alternating the two included 2.0Ah batteries, and the fast charger gets you back in action quicker.
The thing that stands out most in owner feedback is how easy the FOKIKIP is to use. The 180-degree adjustable handle and 54-degree rotatable cutting head make reaching under fences and around corners less of a chore. The trimmer also ships with six bonus replacement spools, stretching your service life by about three times before you need to buy more line. However, buyers have a clear note of caution: this trimmer handles light jobs beautifully, but as one owner put it, it “can only handle very light jobs… not for heavily grassy or weedy areas.” Keep expectations in check for tougher terrain.
Affordable cordless option
- Two speeds let you dial in power for light trimming or tougher weeds
- Six pre-wound spools included — a huge long-term value
- Automatic line feed keeps trimming uninterrupted
- Adjustable 180° handle and 54° rotating head for hard-to-reach spots
Plastic build quality
- Struggles with heavy, dense vegetation — stick to grass and light weeds
- Some users report a learning curve with the pedal-operated edging switch
Ideal for: the homeowner who wants speed control and lots of spare line for routine lawn upkeep.
Not for: overgrown lots or thick brush where serious cutting power is needed.
3. BLACK+DECKER 20V MAX LST300
BLACK+DECKER’s proven 20V trimmer offers reliable, lightweight trimming for routine yard maintenance.
You get the cordless trimmer that proved battery-powered lawn care could work. The PowerDrive Transmission spins at 6200 RPM, sending more torque to the cutting string than earlier models, so you push through grass and light undergrowth faster. The Automatic Feed Spool (AFS) is a standout convenience: it feeds additional line every time the trimmer starts, so you never bump the head mid-job. At 5.7 pounds with a 12-inch cutting swath, you can easily maneuver it with one hand while guiding the head around trees and fence posts.
The 2-in-1 conversion from trimmer to edger takes seconds — pivot the head and lock it into place. Owners consistently call it “lightweight and easy to handle,” and many note that a single battery charge covers their entire yard. The 2.0Ah lithium-ion battery offers more runtime than BLACK+DECKER’s previous LBXR20 pack. A wall-mountable charging base is included, so the tool stays organized. The honest downside: at 6200 RPM, it’s not the fastest or most powerful option on the block, and the single battery means runtime is capped at about 15–20 minutes of continuous heavy use. If you have a larger property, a second battery is a near-necessity.
Best for: anyone wanting a proven, lightweight trimmer for routine small-yard maintenance with zero hassles.
Consider another if: your yard is large or overgrown — the 2.0Ah battery and 6200 RPM motor feel stretched.
4. CRAFTSMAN V20 String Trimmer (CMCST901M1)
With a 4.0Ah battery providing up to 63 minutes of runtime, this trimmer outlasts most competitors on a single charge.
You get a solution to the runtime problem: the V20 trimmer kit includes a 4.0Ah battery, good for up to 63 minutes of runtime on a single charge. That’s enough to handle most suburban yards without swapping packs. According to the manufacturer, the motor delivers increased power compared to previous trimmers, and the 13-inch cutting swath covers more ground per pass than the 12-inch competition. Two speed settings let you prioritize battery conservation or cutting muscle depending on what you’re dealing with.
The “Turn-To-Edge” functionality means you rotate the head to switch from trimming to edging without any separate attachment. Adjustable height and handle positions keep you comfortable across the session. Early owner reports highlight that the battery “handled really thick weeds” and lasted through 30–40 minute yard sessions without running out. The trade-off? The trimmer uses a relatively light 0.065-inch line, which some buyers find less effective for precise edging against hard surfaces. The trimmer also uses CRAFTSMAN’s V20 battery platform, so if you already own other V20 tools, this one slides right into your existing battery family.
Reach for this when: you want the longest runtime possible on a single charge and a wider 13-inch cut.
Pass on it if: you need heavier line for aggressive edging or prefer an auto-feed system over bump-feed.
5. BLACK+DECKER 20V MAX LSTE525
Two batteries and a push-button feed — a productivity-focused evolution.
You get everything that made the LST300 popular, plus a second battery and a more refined line feed. The EasyFeed system advances line with a push of a button instead of auto-start feed, giving you direct control over how much string extends. Two LBXR20 2.0Ah batteries are included for extended runtime, and the 2-speed control lets you toggle between power mode for thick grass and runtime mode for lighter maintenance. The PowerDrive Transmission increases torque for more cutting power at the string, and the 12-inch steel deck handles the abuse of rocky edges.
The trimmer converts to a wheeled edger by twisting the head, a system owners find “light and simple.” The adjustable height and handle, combined with a premium micro-texture grip, reduce fatigue over longer sessions. Owners appreciate the consistency of the auto-feed and the ability to swap batteries when one dies. The common complaint over years of use is the plastic trigger mechanism — some owners mention it eventually wears out, requiring a simple file adjustment to restore function. At 5.3 pounds, it’s slightly lighter than the LST300, making it a strong choice for anyone who finds gas trimmers too cumbersome.
Ideal for: anyone who wants two batteries for uninterrupted trimming and a more controlled push-button line feed.
Worth noting: the plastic trigger mechanism can wear over time; treat it gently during storage and use.
6. WORX 3-in-1 Cordless String Trimmer (WG173)
This 3-in-1 tool combines trimming, edging, and mini-mowing with a brushless motor for extended runtime and power.
The WORX WG173 is the most versatile tool on this list. Beyond trimming and edging, a third mode converts it into a mini-mower for covering larger areas with enhanced deck-like coverage. The brushless motor is the key upgrade here: WORX claims it offers extended runtime, more power, and a longer lifespan than a standard brushed motor. The dual-line design with 0.065-inch string and a 13-inch cutting diameter makes the trimming area larger than their GT series, according to the manufacturer. The Command Feed technology advances line with a simple button press — no bumping, no automatic feed surprises.
At 6.62 pounds, it’s heavier than the budget picks but still manageable thanks to a 90-degree pivoting head, adjustable auxiliary handle, and telescopic shaft. The included Power Share PRO 4.0Ah battery provides longer runtime than the previous GT series. Owners with multiple WORX tools love that the battery works across 140+ tools in the Power Share platform. The double-line design is a crowd-pleaser for cutting efficiency, though a few owners note that the stock WORX trimmer line can fuse together after sitting; using off-brand line is a common workaround. This trimmer is ideal for homeowners who want one tool that does three jobs well.
Best for: the multi-tasker who wants a trimmer, edger, and mower in one package with brushless efficiency.
The catch: the 6.62 lb weight is higher than budget trimmers, and the stock line may fuse during storage.
7. EGO POWER+ ST1620T
EGO’s 56V brushless trimmer delivers gas-level cutting power with a 16-inch swath and carbon fiber shaft.
EGO’s ST1620T is the premium statement: a 56-volt, brushless trimmer using a telescopic carbon fiber shaft that’s both lightweight and backed by a lifetime warranty (when registered within 90 days). The 16-inch cutting swath is the widest on this list, letting you clear strips faster. LINE IQ technology handles line feed automatically at high performance levels — no bumping, no buttons. POWERLOAD spools line into the head by pressing a button, making reloading a one-step operation rather than a wrestling match.
The high-efficiency brushless motor pairs with a digital 2-speed selector. Recommended with an EGO 4.0Ah 56V ARC Lithium battery (sold separately), you can expect up to 60 minutes of cut time on a single charge. Owners with acreage report using it across “2 summers on a 12 acre farmette” without complaints, calling it “the best weed eater ever.” The dual-line spiral-twist 0.095-inch line is professional-grade, capable of cutting through thick growth that would stop lesser trimmers. The trade-off is significant: the battery and charger are not included in the box, and the 56V system is a separate investment. A small number of customers note occasional line feed jams, but the overwhelming consensus is that EGO delivers gas-level power without the fumes.
Ideal for: property owners with large or overgrown lots who want gas-like performance and the convenience of battery power.
Key consideration: battery and charger are sold separately — factor that into your total spend if you are not already in the EGO ecosystem.
8. Milwaukee M18 2825-20ST
Milwaukee’s M18 trimmer offers commercial-grade build and a 16-inch swath for heavy weeds and dense growth.
The Milwaukee 2825-20ST is built for the user who beats on their tools and expects them to answer back. The 16-inch cutting swath and brushless motor deliver ample power to handle heavy saw grass and dense weeds. At 14.65 pounds, it is the heaviest trimmer on this list, but the weight is offset by the well-balanced, ergonomic design that owners praise for reducing fatigue during extended sessions. The M18 battery platform (sold separately) means it shares power with Milwaukee’s enormous lineup of professional tools.
Performance earns the top billing from owners, who note that the trimmer “handled heavy cutting for over 30 min” on a 5.0Ah battery and matches the power of a 30cc gas trimmer without the pull-start frustration. The bump-feed line system is simple, though some owners in gravel areas prefer to manually pull line instead of bumping it. The battery life receives mixed feedback — while some find it lasts longer than expected, others wish for more runtime, particularly with smaller-capacity packs. This trimmer is best suited for someone already invested in Milwaukee’s M18 system or anyone who wants a single, powerful tool for serious residential weed control.
Reach for this if: you need tough, durable construction for heavy weeds and already own M18 batteries.
Think twice if: you prioritize ultra-light weight or don’t have an existing M18 battery investment — the tool alone is battery-free.
9. Makita XRU12SM1
Makita’s three-speed control lets you dial in exactly 4,000, 5,000, or 6,000 RPM for precise trimming.
Makita’s XRU12SM1 offers a level of speed customization no other trimmer here matches. Three distinct speed settings — Low at 4,000 RPM, Medium at 5,000 RPM, and High at 6,000 RPM — let you dial in exactly the cutting aggression for the job. The BL Brushless Motor delivers up to 6,000 RPM, and the Automatic Torque Drive Technology automatically shifts RPM between extended runtime and added power depending on the load. The bump-and-feed trimmer head comes loaded with 0.080-inch twisted quiet line, which is heavier than the standard 0.065-inch line found on most budget trimmers.
Owners consistently praise the quality and build of this trimmer. At 12 pounds, it’s lighter than the Milwaukee but heavier than the budget options, and the well-balanced design makes it feel manageable. The included 4.0Ah battery and charger mean you have everything from the start to get started. Run time is a common point of discussion: some reviewers point out 35 minutes at medium speed in thick undergrowth, while others find a full charge yields closer to 25–30 minutes of continuous use. The battery is part of Makita’s 18V LXT platform, the largest cordless tool system in the world, so if you already run Makita tools, this is a smooth addition. The exposed razor blade on the shroud is a noted safety concern for households with children.
Best for: the Makita tool owner who wants precise speed control and excellent build quality in a cordless trimmer.
The honest limit: runtime on the included 4.0Ah battery can be tight for larger properties — consider a higher-capacity pack for extended sessions.
Understanding the Specs
Cutting Swath
The cutting swath is the width of grass the trimmer clears in a single sweep. A wider swath, like 13 inches or 16 inches, finishes large areas faster because you make fewer passes. A 12-inch swath is easier to maneuver in tight spots around flower beds and fences.
Battery Amp-Hours (Ah)
Amp-hours tell you the battery’s energy capacity. A 4.0Ah battery stores more energy than a 2.0Ah pack at the same voltage, so it typically runs longer. For a trimmer, higher Ah means fewer battery swaps and longer uninterrupted trimming sessions.
