The whole point of an electric edger and trimmer is to leave your yard looking crisp without wrestling with gas fumes or getting tangled in a cord. The top models here let you switch between trimming grass and edging along a sidewalk in seconds, so you get a professional look without buying two separate tools. But battery size, cutting width, and how the line feeds out vary a lot from one model to the next. Pick the wrong one and you will be stuck with a dead battery or a jammed spool halfway through the front yard.
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.
For most homeowners, the right electric edger and trimmer balances enough runtime to finish the whole property with a lightweight design that does not leave your arms sore. The six models below each take a slightly different approach to hitting that balance.

How To Choose The Best Electric Edger And Trimmer
The right tool depends on your yard size, how close you are to an outlet, and how much you want to carry. Here are the three specs that separate a great purchase from a frustrating one.
Battery Capacity vs. Runtime
On these cordless models, voltage is almost always 20V or 21V. So what really determines how long you cut is the amp-hour (Ah) rating on the battery. A 4.0 Ah battery lasts about twice as long as a 2.0 Ah battery under the same load, because it stores twice the energy. If you have a medium-to-large yard, look for a kit that comes with two batteries or at least one high-capacity pack, so you are not stuck waiting for a recharge mid-job.
Cutting Width and Power
Cutting width—measured in inches—tells you how wide a swath the trimmer clears with each pass. A 14-inch head finishes the job faster than a 12-inch head, because you cover more ground per sweep. But a wider head also demands more power from the motor. Most cordless models land at 12 or 13 inches, while corded units can push to 14 inches because they draw unlimited power from the wall. For edging, a narrower head is actually easier to guide along a curb.
Line Feed System
The biggest daily frustration with a string trimmer is stopping to yank out more line. An automatic feed system advances the line each time the motor starts, so you never bump the head on the ground. A bump-feed system requires you to tap the head on the ground, which can be annoying. The smoothest option is a button-press feed, which gives you precise control over exactly how much line releases without wasting it.

In‑Depth Reviews
1. WeGofly 4-in-1 Cordless String Trimmer
A brushless beast that cuts brush all afternoon without asking for a recharge.
The WeGofly 4-in-1 is the one you reach for when the yard is more wilderness than lawn. It runs on a 15000 RPM brushless motor (a motor type with no brushes to wear out, lasting longer and running more efficiently) and comes with two 21V 6.0 Ah batteries—the largest capacity in this lineup. Buyers report they cleared a couple of acres of brush in two days without draining the packs, and at 5.2 pounds it is the lightest model here despite carrying the most battery weight. The 13-inch cutting width lets you cover ground faster than the 12-inch units, and the included metal blades and saw blades turn it into a brush cutter for thick overgrowth beyond what string can handle. One reviewer noted that the auxiliary pull screws can loosen during heavy work, so keep an eye on them. This machine is overkill for a postage-stamp yard, but if you have serious vegetation, it is the one that gets the job done.
Unlike the corded BLACK+DECKER, which stops where the extension cord ends, the WeGofly goes anywhere on the property thanks to its dual-battery setup. The brushless motor also runs quieter than a gas equivalent, so your neighbors will not glare at you on a Saturday morning. With a 3-year warranty on the machine and a 2-year warranty on the batteries, the maker backs it with more coverage than most competitors.
Why It Stands Out
- Massive 2 x 6.0 Ah batteries for all-day runtime up to 2 hours
- 15000 RPM brushless motor with steel gears for tough brush
- Lightest in the group at 5.2 pounds despite the power
- 4-in-1 design: trimmer, edger, mini mower, brush cutter
Watch Out For
- Auxiliary pull screws may loosen during heavy use
- More tool than you need for a small manicured lawn
Reach for it if: your yard has thick brush, blackberries, or small saplings and you want one tool that handles all of it without running out of battery.
Think twice if: you just need light trimming around a small lawn—the power and battery capacity are more than you will use.
2. WORX WG173 3-in-1 Cordless String Trimmer
You get a 13-inch cut and a button-press line feed that beats bumping the head on every curb.
The WORX WG173 earns its spot as the best overall pick because it solves the two biggest annoyances with string trimmers: advancing the line and switching modes. It uses a Command Feed system—you press a button on the handle to release more line, so you never tap the head on the ground like you do with a bump-feed trimmer. It switches between trimmer, wheeled edger, and mini-mower modes. The 13-inch cutting diameter with a dual-line 0.065-inch design trims a significantly wider path than narrower single-line models. The brushless motor (no physical brushes to wear down) runs cooler and longer than a standard brushed motor. A reviewer noted a specific quirk: the charger can slowly drain the battery if you leave the battery on the plugged-in charger for days, so pull it off when fully charged. At 6.6 pounds it is not the lightest, but the telescopic shaft and adjustable handle let you dial in the fit.
The WORX also works within the Power Share ecosystem: the same 20V battery fits over 140 other WORX tools, from blowers to chainsaws, so you are buying into a system rather than a one-off battery. Compared to the FOKIKIP model with its two 2.0 Ah batteries, the WORX ships with a single 4.0 Ah pack, but the brushless motor is more efficient so you get longer runtime per charge than their previous GT series. Buyers consistently call it one of the best battery-operated trimmers they have used, specifically praising how it cuts through thick weeds without bogging down. If you want convenient line feed and mode switching from one tool, this is the one.
Strengths
- Command Feed button lets you advance line without bumping
- 3-in-1 modes: trimmer, wheeled edger, mini mower
- Brushless motor is more efficient and powerful than standard motors
- Interchangeable with 140+ WORX Power Share tools
Quirks
- Charger drains battery if left plugged in for days (reviewer confirmed with multiple chargers)
- Only one 4.0 Ah battery included, not two
Who this is for: the homeowner who values convenience—button-press line feed, tool-free mode switching, and a battery that works across a whole family of outdoor tools.
Who might pass: anyone with a large yard needing two full battery packs from the start, or those who prefer a lighter single-purpose tool.
3. RAXONE 21V Weed Wacker Cordless & Lawn Edger
Packs two 4.0 Ah batteries and ten spare spools at a mid-range price that undersells its runtime.
The RAXONE is the value champion because it nails the two things buyers actually run out of: battery life and spare line. Owners mention it “comes with two 4Ah Li-ion batteries,” and the maker claims the pair delivers over 60-90 minutes of runtime—enough to finish a typical yard without swapping packs mid-task. The 9500 RPM motor spins a 12-inch cutting path, and that speed beats the 8500 RPM JKLARI model for a similar-size head. It weighs 6.17 pounds, versus the JKLARI’s 7 pounds, so your arms stay fresher longer. The head rotates 90° for edging, and the automatic line feed means you do not stop to tap or pull. One reviewer called it the best weed wacker they have ever used, specifically noting that the battery “lasts longer that I can.” The trade-off is that at 12 inches, the cutting width is smaller than the 14-inch BLACK+DECKER, so you make more passes. Still, for the money, you get two large-capacity batteries and a 9500 RPM motor that few competitors at this tier match.
The dual-interlock switch (you press two points at once) prevents accidental startup, which is a real safety win if you have kids around. The unit also includes 10 pre-wound spools, so you are set for months without buying replacement line. If you want cordless freedom, two big batteries, and a motor that punches above its price, this is the one to beat.
Best Reasons To Buy
- Two 4.0 Ah batteries give long runtime, confirmed by reviewers
- 9500 RPM motor is faster than several similarly priced competitors
- 10 included spare spools save money over time
- Lightweight at 6.17 pounds with a comfortable adjustable handle
What To Consider
- 12-inch cutting width means more passes than a 14-inch model
- Brand recognition is lower than BLACK+DECKER or WORX
Grab this if: battery life is your top concern and you want a cordless trimmer that does not force you to stop halfway through the yard.
Look elsewhere if: you need the wider 14-inch cut of a corded model for large areas, or you prefer a well-known national brand.
4. FOKIKIP 21V 2-in-1 String Trimmer & Edger
A dual-speed trimmer that lets you dial down power for delicate work or crank it up for thick weeds.
The FOKIKIP stands out by giving you a choice of two speed modes—low for daily trimming and fine work along flower beds, high for dense or thick weeds that need extra torque. It uses two 2.0 Ah batteries that deliver up to 45 minutes of combined runtime, which suits small to medium-sized yards. The automatic line feed advances the line every time you start the machine, and the maker includes six bonus replacement spools so you are set for several seasons. The 180-degree adjustable handle and 54-degree rotatable cutting head make it easy to reach under fences and around corners. The edging mode is activated by stepping on a pedal at the head and rotating the machine 90° to the right, which is tool-free and quick. Customers note this trimmer leaves the lawn “looking clean and professionally maintained” and that the adjustable handle makes it comfortable for extended use. One note: before first use, untie the knot in the pre-installed line so the auto-feed works correctly—some reviews suggest skipping that step causes frustration. It is a solid mid-range choice with better speed control than most cordless trimmers at its level.
Unlike the single-speed RAXONE, the FOKIKIP gives you the option to slow down when you are edging near flowers or delicate plants, reducing the chance of accidental damage. The battery life does not match the RAXONE’s dual 4.0 Ah packs, but for a small yard the 45 minutes of total runtime is plenty. The 1-year warranty provides basic confidence, though it is shorter than the WeGofly’s 3-year coverage on the main unit.
What Works Well
- Two speed modes give you precise control for different conditions
- Tool-free conversion from trimmer to edger using a foot pedal
- Includes 6 bonus spools for long-term use
- 180-degree adjustable handle for reaching tight spaces
What To Note
- Only 2.0 Ah batteries, so runtime is shorter than dual-4.0 Ah alternatives
- Pre-installed line knot must be untied before first use or auto-feed fails
Choose this for: a small-to-medium yard where you want speed control for precision edging and trimming without overcomplicating the tool.
skip it if: your yard is large enough that 45 minutes of total battery run time will leave you short before the job is done.
5. JKLARI 21V Cordless Weed Wacker & Edger
An entry-level cordless that keeps the price low by keeping the batteries small.
The JKLARI is a straightforward 2-in-1 trimmer and edger that fits the budget without being a toy. It spins at 8500 RPM with a 12-inch cutting path, and comes with two 21V 2.0 Ah batteries. One buyer mentioned “one battery lasted about 30–40 minutes of continuous trimming,” which is enough for a typical small yard. At 7 pounds, it is the heaviest unit here—versus the RAXONE’s 6.17 pounds—so you will feel the weight more after 20 minutes. The automatic line feed is supposed to adjust the line for you, but several reviewers point out it is “hit or miss” and they had to manually adjust it. On the plus side, the 180-degree folding shaft makes storage easy in a garage corner or shed, and the 1-year warranty covers basic defects. The safety lock prevents accidental starts, which is helpful around children. If you have a tiny yard and a tight budget, this machine will get the job done, but the QA on the auto-feed is inconsistent.
It falls short of the RAXONE in both motor speed (8500 RPM vs 9500 RPM) and total battery capacity (two 2.0 Ah vs two 4.0 Ah), and the weight is higher. For someone who just wants a cordless option under a certain price point for light trimming around flower beds and sidewalks, the JKLARI is functional and folds away neatly. Just budget for occasional manual line adjustment.
What You Get
- Very affordable cordless 2-in-1 option for small yards
- 180-degree folding shaft for compact storage
- Two batteries included for alternating use
- Easy assembly and simple operation
The Drawbacks
- 7 pounds is the heaviest in the lineup, causing fatigue over time
- Automatic line feed is unreliable according to some buyers
- 8500 RPM motor is slower than several competitors
This is for: the casual homeowner who only trims a small patch, does not want to spend much, and values easy storage over long runtime.
Pass on it if: you have a medium-to-large yard or thick overgrowth—the smaller batteries and heavier frame will make the work harder than it needs to be.
6. BLACK+DECKer BESTA510 2-in-1 String Trimmer
The corded workhorse that never runs out of power, as long as you stay near an outlet.
If you never want to think about battery life, the BLACK+DECKER BESTA510 is the simplest solution. It draws a continuous 6.5 amps from the wall through a POWERDRIVE transmission (a geared system that delivers maximum torque to the cutting head), so the 14-inch cutting head never slows down as the battery drains—because there is no battery. Shoppers say it is “lightweight, powerful, and affordable electric weed eater” and that it “cuts better than battery models (e.g., Ryobi) with consistent power.” The 14-inch cut path is the widest in this lineup, at 14 inches versus the 12-inch models, so you finish faster. The design rotates from trimmer to wheeled edger by twisting the shaft, and the automatic feed spool eliminates bumping. The trade-off is obvious: you drag an extension cord everywhere. One reviewer fixed a cord-retention issue by looping the cord through the handle, and another noted the auto-feed can waste line by feeding too fast (they added a small spring to slow it). At 6.3 pounds it is lighter than the JKLARI and close to the RAXONE. For a small yard with easy outlet access, this is the most reliable performer of the group.
The 2-year limited warranty and 30-day money-back guarantee add confidence. Unlike the cordless options, there is zero worry about battery degradation after a season or two—this trimmer will run the same on year five as it did on day one. The downside is that the cord retention system can fail if not looped correctly, and the automatic line feed on this particular model tends to over-feed, so you may waste some line if you do not modify it. Still, for pure, uninterrupted cutting power at the lowest buy-in, the BESTA510 is the proven classic.
The Core Strengths
- Continuous 6.5 amp power means no battery fade mid-yard
- 14-inch cutting width is the widest here, covering ground faster
- Lightweight at 6.3 pounds for a corded trimmer
- Made in the USA according to customer reviews
The Strings Attached
- You must manage an extension cord across the yard
- Automatic feed can over-feed line, wasting some
- Cord retention system needs a specific loop method to stay secure
Pick this if: you want maximum cut width, consistent power, and the lowest long-term cost—and your yard has easy access to an outdoor outlet.
Pass on it if: you have a large yard far from an outlet, or if the cord will be a constant tripping hazard for you.
Understanding the Specs
Cutting Width (Inches)
The cutting width is the diameter of the circle the trimmer line sweeps. A 14-inch head clears a wider path than a 12-inch head, so you need fewer passes to cover the same area. On a 5,000-square-foot lawn, that difference shaves real time off your chore. Wider heads also demand more motor power to spin effectively, which is why corded models can hit 14 inches while cordless units often stay at 12 or 13 inches to preserve battery life.
Battery Capacity (Ah)
Amp-hours (Ah) tell you how much energy the battery stores. A 4.0 Ah battery holds twice the charge of a 2.0 Ah battery, so it runs roughly twice as long before needing a recharge. Voltage is mostly standardized at 20V-21V for these trimmers, so Ah is the number that actually predicts runtime. Kits with two batteries let you swap and keep cutting, effectively doubling your work time without waiting for a charge cycle.
