A weed eater should make yard work easier, not leave your arms aching the next day. If you are a woman looking for a lightweight weed eater for a woman, the single most important spec is the weight — under 5 pounds means you can trim, edge, and clean up without fighting the tool itself.
I’m Rikta — the founder and writer behind Lawn Gear Lab. 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.
The seven picks reviewed here all weigh under 8 pounds, so you can focus on the differences in battery life, cutting width, and adjustability that actually matter when you are the one holding the tool. Finding the right lightweight weed eater for a woman depends on matching your yard size with a trimmer that fits your height and grip strength.

How To Choose The Best Lightweight Weed Eater For A Woman
Picking a trimmer for a woman depends on three things: how much you can comfortably carry, how long you can work before recharging, and whether the tool adjusts to your height. The wrong pick leads to a sore back and a half-finished yard, so here is what to check before you buy.
Weight And Balance: The Make-Or-Break Spec
The weight of the machine, listed in pounds, is the first number you should look at. A trimmer under 5 pounds, like the 3.5-pound pick we cover next, lets you work one-handed if needed, which matters for reaching tricky spots. A tool that weighs 7 pounds feels fine for the first five minutes, but the fatigue adds up fast if your yard takes longer. Keep in mind that a higher voltage battery sometimes adds weight, so consider the trade-off if your yard is small.
Battery System And Runtime
Look for a trimmer that includes two batteries in the box. Most 20V and 21V models with 2.0Ah (amp-hour) batteries give you about 20 to 40 minutes of runtime per battery. Two batteries mean you can swap and finish your yard without waiting for a charge. The difference between 20V and 24V is not huge for light grass and weeds, but the 24V Greenworks we review has slightly more headroom for thicker growth, while still staying at a light 5.2 pounds.
Adjustable Shaft And Handle
A telescoping shaft, which lets you extend the length from about 33 inches to 43 inches, is a huge advantage if you are on the shorter side. A trimmer that is too long forces you to lean or hunch, which strains your lower back. The head of the trimmer should also rotate, ideally 180 degrees, so you can edge sidewalks and flower beds without twisting your wrist into an awkward angle.

In‑Depth Reviews
1. goodjob 20V 12″ Cordless Weed Wacker, 3.5 lbs Ultra-Lightweight String Trimmer
The featherweight that lets you trim one-handed without your arm tiring first.
At just 3.5 pounds, this is the lightest trimmer in the lineup — lighter than the NovorikX (3.7 lbs) and less than half the weight of the JKLARI at 7 pounds. The 20V motor delivers enough power for routine trimming and edging, and the 12-inch cutting swath covers ground efficiently without adding bulk. The 180-degree pivoting head reaches under fences and around trees, so you do not need to crouch or strain.
Buyers report the dual 2.0Ah batteries give about 30 minutes of runtime each, which covers a medium lawn. One reviewer noted larger weeds drained the battery to roughly 10 minutes, but the six spare spools included in the box keep you running. The auto-feed system advances line as you work — no bumping required — and the noise level stays below 75 dB, quiet enough for early morning use without annoying the neighbors.
Why it wins for everyday trimming
- Weighs only 3.5 lbs — you can hold it in one hand while resting your other arm.
- Comes with two batteries and six spare spools, so you are not buying extras soon.
- 180° pivoting head makes edging around flower beds easy.
Where it has limits
- Battery life drops noticeably in tall, thick weeds (some reviewers reported ~10 minutes).
- The included trimmer line is fragile; the 6 spare spools help, but upgrading to aftermarket.065″ line is a good idea.
Your everyday partner: Grab this if your yard is small to medium and you want the lightest possible tool you can swing all afternoon without fatigue.
One honest drawback: It is not built for heavy overgrowth — stick to the 21V JKLARI or the 24V Greenworks if you have a lot of thick brush.
2. Greenworks 24V Cordless String Trimmer/Edger (Gen 2), 12″ Cutting Width, Ultra-Light 6 lbs Design
More voltage without the weight penalty — the best power-to-heft ratio here.
While most trimmers at this weight run on 20V, the Greenworks delivers 24V (a 20% higher voltage than the goodjob 20V) while staying at a manageable 5.2 pounds. That extra voltage helps the motor spin through thicker grass and stubborn weeds without bogging down as much. The telescoping aluminum shaft adjusts from 4’8” to 6’5”, so it fits shorter women without forcing a hunch — a real advantage over fixed-shaft designs.
Owners mention the rotating 90-degree head makes edging walkways and tree rings simple. One reviewer called it “a girl’s girl” tool, praising its lighter feel and aggressive cutting power. The auto-feed.065″ line system is smooth when it works, though a few reviewers noted the spool can jam or fail to advance, requiring manual restringing. The battery is rated for about 30 minutes and shares compatibility with over 150 other Greenworks 24V tools (chainsaws, leaf blowers), so if you already own Greenworks gear, this trimmer slots right in.
what separates it
- 24V motor gives more cutting torque than 20V rivals while staying light.
- Telescoping shaft fits a wide height range — from 4’8″ to 6’5″.
- Shared battery platform works with dozens of Greenworks 24V tools.
Watch out for
- Auto-feed spool can be finicky — some users had to manually restring every few minutes.
- Battery life can degrade after several uses, per some reviewers.
Reach for this if: You want the best mix of power and lightness and are okay tinkering with the auto-feed occasionally — the 24V system is a real boost for thicker grass.
Look elsewhere if: You need flawless, jam-free line feed from day one; the goodjob or WORX have more reliable auto-feed histories.
3. NovorikX 20V String Trimmer Cordless, 12 Inch, 3.7lbs Ultra Light Weight Weed Wacker
A telescoping shaft that adjusts to your height — a huge comfort win for shorter women.
At 3.7 pounds, the NovorikX is barely heavier than the 3.5-pound goodjob, but it adds a telescoping handle that extends from 33 inches to 43 inches. That adjustability is a standout if you are under 5’4″, because you can set the shaft so the cutting head reaches the ground without you leaning forward. The 180-degree rotating handle and 3-position head also help you edge flower beds without twisting your wrist.
The motor spins at 7000 RPM with a 12-inch cutting swath, which customers note is perfect for light grass and small weeds but struggles on thick brush. Each 20V 2.0Ah battery delivers about 22 minutes of runtime, and with two batteries in the box, you get about 44 minutes total. One buyer mentioned the battery lasts 20-25 minutes per charge, giving roughly 40 minutes of total runtime — enough for a 1/4-acre yard. The built-in plant guard protects your flowers while you edge, a thoughtful touch. The manufacturer backs this with a 3-year tool warranty and 2-year battery warranty, which is strong for this price tier.
Standout advantages
- Telescoping shaft (33″ to 43″) fits shorter users perfectly — no hunching.
- Ultra-light 3.7 lbs with a 3-year tool warranty for confidence.
- Built-in flower guard prevents damage while edging tight beds.
Heads up
- Weak on thick brush and woody stalks — light trimming only.
- Battery drains fast on heavy vegetation; runtime is just 22 minutes per battery.
Perfect if: You are under 5’6″ and want a trimmer that adjusts to your natural posture — the telescoping shaft makes a real difference in back comfort.
Consider something else if: Your yard has dense, tall weeds or brush; the 24V Greenworks or the 21V JKLARI handle heavier growth better.
4. Cordless Weed Wacker, 21V Battery Powered Grass Trimmer & Edger 2-in-1 (JKLARI)
The one that keeps running and comes with enough spools to last a season.
This is the heaviest pick at 7 pounds, but it earns its space with a 21V motor that spins at 8500 RPM — the highest no-load speed in this lineup — and an exceptional 40-minute average battery life per battery. That is 82% more runtime per battery than the NovorikX’s 22 minutes, so you can tackle larger yards without swapping as often. The two 2.0Ah batteries and 8 spare spools mean you are set for months of trimming before you need to buy string.
Reviewers point out the 2-in-1 design switches from trimmer to edger quickly, and the 60-degree shaft angle adjustment plus 180-degree handle rotation give you a lot of flexibility around obstacles. One owner reported it handled overgrown yards with ease, calling it a “lightweight powerhouse.” The automatic line-feed system eliminates bumping, though a few users found the auto-feed unreliable and had to adjust the line manually. The folding design stores compactly in a corner or shed.
Why it is worth the extra ounces
- Longest battery life of the bunch — 40 minutes per battery, two included.
- 8 spare spools included — you will not need to buy string for a long time.
- 8500 RPM motor cuts through overgrown yards and blackberry bushes.
Where it is not perfect
- At 7 lbs, it is twice the weight of the 3.5 lb goodjob — fatigue builds faster.
- Auto-feed system is not always reliable; some users need to manually adjust the line.
Stick with this if: Your yard is medium to large and overgrown — the long battery life and extra spools save you from constant interruptions.
skip it if: You have arthritis or very limited arm strength; the 7-pound weight may tire you out before the battery does.
5. BLACK+DECKER 20V MAX String Trimmer and Edger 2 in 1, LST300
A dependable name with automatic line feed — less tinkering, more trimming.
BLACK+DECKER has been making string trimmers for decades, and the LST300 is a solid mid-range option at 5.7 pounds. The POWERDRIVE transmission delivers 6200 RPM to the cutting string, which shoppers say is enough for routine grass and light weeds, though it is less powerful than previous models according to some. The Automatic Feed Spool (AFS) system feeds line when needed with no bumping, and buyers consistently praise it as reliable — a real plus if you hate fiddling with line.
The 2-in-1 conversion to edging takes seconds, and the adjustable handle and height positions give you decent comfort control. Buyers report the single 2.0Ah battery covers an entire yard for many, but a few users report a runtime around 15 minutes and a several-hour charge time. The trimmer is quiet and easy to start, and the 12-inch cutting swath is standard. The 2-year limited warranty provides a safety net, though some buyers had issues with the charger failing.
Why it is a safe bet
- Auto-feed spool works reliably — no bumping or manual line pulling needed.
- Lightweight at 5.7 lbs with comfortable adjustable handle.
- Quieter than gas and compatible with other BLACK+DECKER 20V batteries.
Known issues
- Battery runtime is short for some users — around 15 minutes per charge.
- Charger can be finicky; a few reviewers had units fail within weeks.
Go for it if: You want a brand you recognize with a proven auto-feed system that actually works — ideal for light, routine yard care.
Be aware: Battery runtime is inconsistent across users; you may need to buy a second battery for larger lawns.
6. WORX Cordless String Trimmer & Lawn Edger, 12″ Electric Weed Wacker, WG163
Rubberized wheels for edging that give you clean, straight lines every pass.
The WORX WG163 is the only trimmer in this roundup with rubberized support wheels that guide the head during edging, making sidewalk and driveway edges look cleaner with less guessing. The 5.5-pound weight is easy to handle for a full session, and the 7600 RPM motor handles grass and moderate weeds well. The push-button Command Feed spool system lets you advance line instantly — no bumping required — and WORX offers a “free spools for life” program that reduces long-term costs.
Reviewers consistently call it lightweight and easy to use, with two batteries handling a well-maintained 1/4-acre lot with no issues. The spacer guard adjusts to protect plants and landscape features, and the 90-degree head tilt helps on sloped terrain. The downsides: the charger is often described as “very snug,” making battery removal difficult, and some users find the height adjustment stiff and the guard too large for precise edging. The trimmer bogs down in thick growth, so it is best for regular maintenance rather than clearing heavy overgrowth.
What makes it unique
- Support wheels make edging stupid-easy — your lines stay straight without practice.
- Push-button instant line feed works reliably, no bumping.
- Free spools for life program (WORX) saves you money on line.
Things to know
- Height adjustment lever is hard to operate — requires significant force.
- Charger is extremely tight; some buyers needed a clamp to remove the battery.
Best for: Anyone who wants crisp, professional-looking edges along sidewalks and driveways — the wheels are a real time-saver.
Not ideal for: Large, overgrown lots or very thick weeds; the motor struggles in heavy growth.
7. beyond by BLACK+DECKER 20V MAX String Trimmer / Edger, 12-Inch (LST522E1AEV)
Two speed settings let you choose power for overgrowth or efficiency for routine trims.
The “beyond” line from BLACK+DECKER adds a feature you rarely see at this weight: a 2-speed control that lets you dial up more power for tough jobs or drop to a slower speed for longer runtime on regular trims. The patented POWERDRIVE transmission increases brush cutter torque to handle overgrowth, and the Automatic Feed Spool (AFS) keeps the line at a full 12 inches without bumping. At 7.58 pounds, it is the heaviest pick here, edging past the JKLARI, but the two-speed system means you are not always using full power, which saves battery when you do not need it.
Owners mention the battery lasts about an hour, which is generous for a single battery system. One reviewer called it “very lightweight and powerful,” noting the edger wheel made the job easier. The adjustable height and pivoting handle add comfort, and the battery is interchangeable with other BLACK+DECKER 20V tools. A common complaint: the trimmer ships with only one battery, and several reviewers received units where the battery refused to charge. The manufacturer offers a 2-year limited warranty, but the single-battery setup is a real limitation for larger yards.
Standout features
- Two speed settings give you flexibility — high for thick weeds, low for longer runtime.
- POWERDRIVE transmission boosts torque for overgrowth.
- Battery lasts roughly an hour, which is strong for a single pack.
Real drawbacks
- Comes with only one battery — you may want to buy a second for larger yards.
- Charger reliability is inconsistent; some units arrive with dead batteries that cannot be charged.
Choose this if: You want the flexibility of two speed settings and already own other BLACK+DECKER 20V tools so the single battery is less of a problem.
Think twice if: You need a tool that works from the start without potential charging issues — the goodjob or WORX have more consistent quality control.
Understanding the Specs
Weight (Pounds)
The single most important number when you are shopping for a lightweight weed eater. Every pound you save means less strain on your shoulders and arms during a 30-minute trimming session. Look for models under 6 pounds — the goodjob and NovorikX at 3.5 and 3.7 pounds are the lightest, while the JKLARI and beyond BLACK+DECKER at 7+ pounds require more upper-body effort but offer longer runtime or more features.
Battery System (Volts & Ah)
Voltage (20V, 21V, 24V) determines cutting power — higher voltage generally cuts thicker grass. Amp-hours (Ah) like 2.0Ah tell you the battery capacity. A 2.0Ah battery at 20V typically runs for 20-40 minutes depending on how thick the grass is. Most trimmers here include two batteries so you can swap and keep working; models with only one battery (like the beyond B+D) may leave you waiting for a recharge mid-job.
Auto-Feed Spool System
An auto-feed system advances the trimmer line automatically as the line wears down, so you do not need to stop and manually pull string or tap the head on the ground. This feature saves time and keeps the cut consistent. The WORX uses a push-button Command Feed that some users prefer, while the Greenworks and JKLARI have had mixed reviews on reliability.
Cutting Width (Inches)
All the picks here offer a 12-inch cutting swath, which is the standard for lightweight residential trimmers. A wider swath covers more ground per pass, but it also requires a slightly more powerful motor to cut through thick grass. For small to medium yards, 12 inches is a solid balance of speed and control.
