Best Cordless Weed Trimmer Edger: 5 Top Picks for a Clean Lawn Edge

You know the drill. You spend an hour mowing, and the lawn still looks unkempt because grass hangs over the sidewalk and creeps up the fence line. A trimmer that can also edge solves that in one pass, but gas models are heavy, loud, and a pain to start. Battery-powered combos promise convenience, yet some choke on thick weeds or die halfway down the driveway.

The best cordless weed trimmer edger balances cutting power, runtime, and weight. You want something that starts instantly, converts from trimming to edging without tools, and doesn’t leave your arms sore. Line feed matters too—bumping the head is old news; automatic feed saves you from stopping every few feet.

We compared five leading models on real-world usability, battery life, and build quality. Whether you have a postage-stamp city lawn or a sprawling suburban yard, one of these will fit. Our top pick goes to the WORX WG163 for its reliable design and lifetime spool program, but the others shine in specific niches. Read on for the full breakdown.

Here’s a quick look at how the five contenders stack up on the specs that matter most.

WORX 20V 12-Inch 2-in-1

The WORX WG163 is the closest thing to a dedicated edger that also trims. It converts from trimmer to edger by pivoting the head 90 degrees, and the rubberized wheels guide you along walkways and driveways for straight, clean lines. This is the tool for homeowners who care more about crisp edges than raw cutting speed.

What stands out is the push-button line feed. No bumping the head on the ground—just press a button and fresh line advances. WORX also runs a free spool program, so you get replacement spools for life (you pay shipping). That alone saves money over time. The head tilts for sloped terrain, and the adjustable spacer guard protects plants and landscape features from accidental damage.

The trade-off: this model does not include a battery or charger. If you don’t already own a WORX 20V battery, factor in that extra cost. It’s also a bit heavier than some competitors, and the motor isn’t the most powerful for thick brush. But for routine lawn maintenance and precise edging, it’s hard to beat.

• 12-inch cutting width with 90-degree tilting head
• Push-button command feed spool system
• Rubberized guide wheels for edging
• Adjustable spacer guard
• Free spools for life program

Best for: Homeowners who prioritize sharp, straight edges along sidewalks and driveways and want a reliable line feed without fuss.

EWORK 2-in-1 Cordless Weed Wacker

If you’re tired of arm fatigue from heavy trimmers, the EWORK is a breath of fresh air at just 4.2 pounds. It’s one of the lightest cordless trimmers available, making it ideal for women, seniors, or anyone who dreads wrestling a bulky machine. The telescoping shaft adjusts to your height, and the rotating handle finds a comfortable angle.

Performance is solid for the weight. The 9000 RPM motor chews through typical grass and weeds, and the 12-inch cutting diameter covers decent ground. The smart auto feed system advances line automatically as it wears—no bumping, no stopping. It comes with two 2.0 Ah batteries and a charger, plus six replacement spools, so you’re set for the season out of the box.

Don’t expect this to handle heavy brush or thick woody stems. It’s built for regular maintenance, not jungle clearing. The batteries are on the smaller side, so you might need both for a large yard. But for the price and the weight, it’s a fantastic value for light-to-medium duty.

• Weighs only 4.2 pounds
• 9000 RPM motor with 12-inch cutting swath
• Includes 2 x 20V 2.0Ah batteries and charger
• Automatic line feed system
• Telescoping shaft and rotating handle

Best for: Anyone who wants a featherweight trimmer-edger combo that’s easy to handle for extended periods without back or arm strain.

WeGofly 13-Inch 4-in-1

The WeGofly is the overachiever of the group. It’s not just a trimmer and edger—it also converts into a mini lawn mower and a brush cutter. That versatility makes it a smart buy for owners of small yards or properties with varied terrain. You can trim under fences, edge the patio, and then tackle overgrown weeds without switching tools.

Power is its party trick. The 15000 RPM brushless motor with steel gears delivers serious torque, and the 13-inch cutting width means fewer passes. You get three cutting options: standard trimmer line, metal blades for thick brush, and saw blades for small shrubs. The two 6.0 Ah batteries provide long runtime, so you can finish the whole yard without recharging.

The catch? It’s heavier and bulkier than the others, and the 4-in-1 conversion takes a bit of fiddling. The metal blades also demand respect—they’ll throw debris, so wear eye protection. But if you need one tool to handle everything from lawn edges to brambles, this is the one.

• 4-in-1: trimmer, edger, mower, brush cutter
• 15000 RPM brushless motor with steel gears
• Includes 2 x 21V 6.0Ah batteries
• Three blade types: line, metal, saw
• 13-inch cutting width

Best for: Owners of small-to-medium properties who want a single tool that can handle everything from precision edging to heavy brush clearing.

BLACK+DECKER 20V MAX String Trimmer

BLACK+DECKER built its reputation on affordable, dependable tools, and the LST300 fits that mold. It’s a straightforward 2-in-1 that converts from trimmer to edger in seconds. The POWERDRIVE transmission boosts power from the motor to the string, and the 6200 RPM motor is enough for standard grass and weeds.

The automatic feed spool (AFS) is a standout feature—it feeds line automatically when needed, so you never bump the head. It’s also noticeably quieter than gas models, and the reduced vibration design makes it comfortable for longer sessions. The adjustable handle and height positions let you dial in the fit.

On the downside, the included battery is a single 2.0 Ah, which may not last for a large yard. You’ll likely want a second battery or a spare. Also, the cutting width is 12 inches, which is fine but not class-leading. It’s best for small to medium lawns where you don’t need extreme power.

• 6200 RPM POWERDRIVE transmission
• Automatic Feed Spool (AFS)
• 12-inch cutting width
• Reduced vibration design
• Battery and charger included

Best for: Budget-conscious buyers who want a reliable, no-frills trimmer-edger for regular lawn upkeep without breaking the bank.

CRAFTSMAN V20 Weed Wacker

CRAFTSMAN brings the V20 CMCST900D1 with a 13-inch cutting swath and two speed settings. That’s a rare combo—you can choose high power for thick weeds or lower speed for extended runtime. The telescoping pole adjusts to your height, and the automatic line feed (at 0.065 inches) handles most vegetation without jamming.

What sets this apart is the runtime flexibility. Two speeds mean you can stretch the battery for a big yard by dropping to a lower setting, or dial up the power for stubborn patches. The 13-inch swath covers ground quickly, and the quick conversion to edging is tool-free. It’s a solid performer for the price.

The included 2.0 Ah battery is on the smaller side, so plan for a spare if your yard is large. Also, the line feed is automatic but not bump-free—it uses a sensor that can occasionally overfeed. Still, for most users, it’s a dependable workhorse.

• 13-inch cutting swath
• Two speed settings
• Automatic 0.065-inch line feed
• Telescoping pole for height adjustment
• Quick conversion from trimmer to edger

Best for: Homeowners with medium to large lawns who want the flexibility to choose between power and battery life on the fly.

How We Chose These Products

We started with a simple question: what does a typical homeowner actually need from a cordless trimmer-edger? The answer is a tool that cuts cleanly, edges without a separate device, and doesn’t leave you exhausted. We looked at cutting width, motor speed, line feed mechanism, and included batteries. Weight was a factor too—nobody wants a backache after 30 minutes.

We also considered real-world usability. Automatic line feed beats bumping, but we checked if it actually works without jamming. Conversion to edging had to be quick and tool-free. Battery life matters, but we prioritized models that include batteries and chargers in the box. Finally, we balanced price against features, knowing that some buyers want a budget option while others need heavy-duty performance.

Buying Guide: What Really Matters

Before you buy, think about your lawn size and the thickest vegetation you’ll tackle. A 12-inch cutting width is fine for regular grass, but if you have overgrown areas, go for 13 inches or look for a brushless motor like the WeGofly’s 15000 RPM. Brushless motors are more efficient and last longer, but they cost more.

Battery system is the next big decision. Some tools (like the WORX) don’t include a battery, which adds to the upfront cost if you’re new to that brand. Others bundle two batteries, which is a huge convenience. Check the amp-hour (Ah) rating—higher Ah means longer runtime. A 2.0 Ah battery might last 20 minutes, while a 6.0 Ah can go for an hour or more.

Line feed is a quality-of-life feature. Bump feed is outdated; automatic feed is better, but make sure it’s reliable. The WORX push-button is a nice middle ground. Also, consider the weight and balance. A 4.2-pound trimmer is easy to handle, but a heavier one with more power might be worth it if you have tough weeds. Finally, check the spool refill process—some are easier than others.

Our Top Recommendation

The WORX WG163 is our overall pick because it nails the core job of edging. The rubberized wheels set it apart—they guide you in a straight line, which is the hardest part of edging. The push-button line feed is intuitive, and the free spools for life program is a genuine cost saver. It’s not the most powerful or the lightest, but it’s the most reliable for the primary task.

If you want a lighter tool for smaller yards, the EWORK is the runner-up. It’s incredibly easy to use and comes with two batteries, making it a great value. For heavy brush and multi-tasking, the WeGofly is the go-to, despite its complexity. Budget buyers will appreciate the BLACK+DECKER, while the CRAFTSMAN suits those who want speed control.

Frequently Asked Questions

Can I use a cordless trimmer edger for thick weeds and brush?

It depends on the model. Standard trimmers with 9000 RPM motors handle regular grass and light weeds. For thick brush, look for a brushless motor with at least 13000 RPM, like the WeGofly, and consider using metal blades instead of line.

How long does a battery last on a cordless trimmer?

Runtime varies by battery capacity and motor speed. A 2.0 Ah battery might last 15-20 minutes on high, while a 6.0 Ah can go 45-60 minutes. Two-speed models like the CRAFTSMAN let you extend runtime by using a lower setting.

Is it worth getting a 2-in-1 trimmer edger, or should I buy separate tools?

For most homeowners, a 2-in-1 saves money and storage space. Conversion takes seconds. If you have a very large property or need professional-grade edging, separate tools might be better, but for the average yard, a combo is the smart choice.

Do I need to buy extra line spools often?

With automatic feed systems, line is consumed faster, but you control the length. The WORX offers free spools for life, which eliminates that cost. Others include several spools in the box, and replacement line is inexpensive. Keep a spare on hand for mid-season.
