The problem with most electric string trimmers is that they do one job well — trimming — and treat edging as an afterthought, leaving you with a wobbly head and a crooked line along your driveway. This guide sorts out the models that actually deliver on both promises, so you pick the one that keeps your lawn looking crisp without the arm fatigue or a second tool.
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 your yard is a tight city patch or a sprawling half-acre, the right electric string trimmer and edger should handle thick grass, deliver clean curb lines, and not leave you hunting for a charger mid-job — here is how the top contenders actually stack up.
Our Picks at a Glance
How To Choose The Best Electric String Trimmer And Edger
An electric string trimmer and edger that only trims well is only half the tool. You need one that pivots into edging mode cleanly, holds enough battery to finish the whole perimeter, and doesn’t weigh you down after twenty minutes. Here are the three specs that separate a great dual-purpose tool from one that frustrates.
Cutting Width & Line Diameter
The cutting width — measured in inches — tells you how much grass you slice in one swing. A 12-inch swath is fine for small yards and tight spots, while a 15- or 16-inch head chews through a larger lawn faster. Equally important is the line diameter: thinner 0.065-inch line handles light grass with less motor strain, but thicker 0.095-inch line powers through dense weeds without snapping every few feet.
Battery Voltage & Amp-Hours (Ah)
Higher voltage (20V vs. 56V) usually means more torque for thick growth, while the amp-hour number tells you how long the battery lasts between charges. A 2.0Ah pack may run 15–25 minutes, enough for a small yard if you have a spare. A 4.0Ah or 5.0Ah pack stretches the runtime to 45 minutes or more, which matters when you are trimming and edging the whole property in one go. Check if the kit includes one battery or two — two batteries let you swap and keep working without a charging break.
Conversion System & Edger Design
Not all trimmers become real edgers. Some simply rotate the head 90 degrees, which works fine for a clean sidewalk line but lacks the precision a guide wheel and depth stop provide. A dedicated edger attachment with an 8-inch blade and a depth-adjust knob gives you that sharp, professional cut along driveways and flower beds. If you plan to edge every time you trim, look for a tool with a wheeled guide or a true edger attachment rather than just a tilted head.

In‑Depth Reviews
1. EGO MHC1603 Multi-Head Combo Kit 16-Inch 56-Volt
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
The EGO that cuts a 16-inch swath and edges with a carbon-fiber blade guide.
This is the combo that makes you wonder why you ever put up with gas fumes or tangly line. The 16-inch cutting width is 33% wider than the 12-inch trimmers here — so you clear more ground with each pass. The carbon fiber shafts on both the trimmer and the edger attachment are lightweight and durable, backed by a lifetime warranty. The 56V 4.0Ah ARC Lithium battery delivers up to 45 minutes of trimming runtime on the STA1600 attachment, or up to 75 minutes on the EA0820 edger if you run it on low.
The POWERLOAD technology is the standout convenience: you drop the line in, push a button, and the spool winds itself in seconds — no disassembly, no wrestling. The edger attachment includes an 8-inch blade and a guide wheel with a depth adjustment knob that lets you set a 3-inch edging depth. Owners who already run EGO gear appreciate that the 56V battery swaps across the brand’s mower, blower, and chainsaw, and the crowd favorite verdict is clear: “Great edger! Powered thru 4 years of overgrowth with no problem.” The tool comes with a 5-year warranty and IPX4 weather-resistant construction, so rain or sprinklers won’t sideline it.
The only real trade-off is weight — owners note the edger feels heavy before you start cutting, but most say it becomes manageable after the first pass. The included shoulder strap helps, and the consensus is that the heft is the price of the pro-grade build.
Versatile multi-head system: Justifies the investment because the 16-inch cut, POWERLOAD spool, and carbon-fiber edger with depth control give you a system that matches gas-powered performance without the maintenance.
Heavy battery weight: Who should think twice — if your yard is under 2,000 square feet, this much machine may be overkill; a lighter 12-inch model will finish the job and store more easily.
Best combo kit you want one tool that trims, edges, and outlasts small yards with the same battery ecosystem — and you value a 5-year warranty.
Skip if portability 25+ pounds of kit sounds like a workout; the heavier build here demands a shoulder strap and some upper-body comfort.
2. EGO POWER+ 15″ String Trimmer and 8″ Edger – MHC1502
The gas-replacement that edges 75 yards without touching its battery reserve.
Owners upgrading from gas-powered trimmers report that this EGO cuts “better than gas Toro” — and it does so without fumes, pull-cords, or carburetor cleaning. The 15-inch cutting head uses a Rapid Reload system pre-wound with 0.095-inch dual-twist line, so thick weeds don’t snap the string mid-swing. The 8-inch edger attachment includes a depth adjustment knob for a 3-inch edging depth, and owners say the edger “works great, adjustable depth, clean cut.”
Functionality and performance are the most-praised aspects — 59 and 57 owners respectively call them out — and the battery life earns consistent praise: one owner edged 75 feet of driveway and “battery not half used.” The 5.0Ah pack is the largest in this roundup, and the IPX4 weather-resistant body means you can work through damp grass without worrying about electrical shorts. The 5-year tool warranty backs the investment.
The catch here is weight — at 25.6 pounds, it is the heaviest tool in this list, and owners unanimously recommend using the shoulder strap. The ease of use rating is mixed specifically because of that heft, especially for shorter users. But the power is undeniable, and the EGO 56V ecosystem means the same battery fits their mower, blower, and chainsaw.
Powerful string trimmer: What wins owners over is the raw cutting power that matches and sometimes beats gas models — the 0.095-inch line and 56V motor chew through overgrowth that stalls lesser trimmers.
Bulky for tight spots: The honest trade-off — this is a heavy tool; the 25.6-pound system demands a shoulder strap and may fatigue a smaller-framed user before the battery runs out.
Best power you have a quarter-acre or more with thick weeds and want a battery system that replaces your gas trimmer and edger for good.
Skip if compact your yard is small or you need something you can swing one-handed — the weight makes this a two-hand, strap-on tool.
3. WORX WG170 12″ 3-in-1 Cordless String Trimmer
The trimmer that also becomes a mini mower for tight spots.
Most trimmers do two jobs — this WORX does three. The 3-in-1 design lets you switch between a string trimmer, an in-line edger, and a nimble mini lawn mower by attaching the wheeled deck. The 12-inch cutting head runs at 7,600 rpm, and owners say it handles 10-inch-tall grass on a 1-acre lot without bogging down. The Command Feed system lets you advance fresh line by pushing a button — no stopping to bump the head.
What buyers praise most is the adjustability: 7 handle positions and 6 rotating head settings let you dial in the perfect angle for edging along curved flower beds or sloped terrain. A 72-year-old owner called it “lightweight and powerful enough” for her needs, and the two included 2.0Ah batteries provide about 25 minutes each, which covers most medium-sized yards. The WORX PowerShare platform means these same batteries run all other WORX 20V and 40V tools.
The recurring gripe involves the wheel mounting plate on the mini-mower attachment — some buyers report it loosens over time and needs a zip-tie or duct tape rig to stay in place. It is a known weak point, but the core trimmer and edger functions hold up well; several owners are on their second or third unit because they like the system enough to replace it.
Affordable 3-in-1
- Three tools in one — trim, edge, and mini-mow without buying separate attachments
- 7 handle positions and 6 head rotations for custom ergonomics
- Command Feed button reloads line instantly without disassembly
Plastic build
- Wheel mounting plate on the mower deck loosens over time; owners often jury-rig it
- Batteries last about 25 minutes each — plan for swapping mid-job on larger lots
Best budget homeowners who want one tool that trims the ditch, edges the driveway, and mows a small patch — without storing three separate machines.
Skip if durability you need a rock-solid mini-mower every time; the wheel attachment weakness means this is a trimmer-first tool with a bonus mowing mode, not a permanent mower replacement.
4. BLACK+DECKER LST522 12″ 20V MAX Cordless Trimmer
The lightweight that edges on wheels — no balancing act required.
What sets this trimmer apart from the 12-inch pack is the wheeled edging system. Instead of tilting the head and guessing the angle, you flip the tool over and run the guide wheel along the curb — it cuts a straight, clean line without wobbling. Performance and weight are the top-praised aspects here, with 473 and 370 owners respectively calling them out. The PowerDrive Transmission boosts torque at the string, so dense grass doesn’t stall the motor.
The included LBXR2520 battery offers 66% more runtime than standard 20V packs — owners mention about 45 minutes of real-world use, which is strong for a 2.5Ah battery. The AFS automatic line feed system advances the string as it wears, so you don’t have to stop and bump. At 5.7 pounds it is light enough that shorter users — one 5’3″ owner specifically loves it — find it comfortable for extended sessions.
Battery life gets mixed reviews overall — some owners wish it lasted longer than 45 minutes, and the tool isn’t designed for coarse brush. But for regular weekly trimming and edging on a small-to-medium lawn, the value is tough to top. The 20V MAX system also means compatibility with a wide range of BLACK+DECKER yard tools.
Lightweight design: The thing everyone raves about is how light it feels — 5.7 pounds with a wheeled edger that makes sidewalk lines easy, especially for smaller-framed users.
Limited runtime: The honest catch — the battery life is fine for a single pass, but if your yard takes longer than 45 minutes, you will want a spare battery on hand.
Best light duty lightweight trimming and wheel-guided edging on small to medium lawns — the easiest way to get straight driveways without a second tool.
Skip for large yards you regularly battle thick brush or have more than a quarter-acre; the motor and battery are best suited to regular maintenance, not overgrowth.
5. CRAFTSMAN V20 CMCST901M1 13″ Cordless Trimmer
The Craftsman that runs 63 minutes on a single charge — the longest in this roundup.
Runtime is the single biggest pain point with battery trimmers, and this Craftsman addresses it head-on with a 4.0Ah battery that the manufacturer rates for up to 63 minutes. Real-world owners confirm the 4.0Ah pack handles an entire yard — one review notes the battery still had one bar left after trimming a 1,400-square-foot lot. The 13-inch cutting swath is one inch wider than most 12-inch models here, so you cover more ground per pass.
The Turn-To-Edge functionality lets you pivot the head for edging, and the adjustable handle customizes the height so you don’t hunch over. Owners praise the lightweight feel and how easy it is to maneuver, with the strongest positive feedback centered on battery life and light weight — each with 11 mentions. The motor is also 52% more powerful than earlier Craftsman V20 trimmers, according to the brand, which helps it slice through wet grass without bogging.
A few owners note that the edging performance with the standard string is decent but not razor-sharp — the lightweight line can flex on hard-packed dirt edges. If you need surgical edging, a dedicated blade attachment or a wheeled guide model may be better. But for all-day trimming without swapping batteries, this Craftsman is the leader.
Reliable V20 system
- Class-leading single-charge runtime — up to 63 minutes with the included 4.0Ah battery
- 13-inch cutting width trims wider than most 12-inch competitors
- 52% more powerful motor than previous V20 trimmers for thick grass
Noisy operation
- Standard string line flexes on hard edging; not as crisp as a dedicated blade edger
- Newer model with fewer long-term durability reviews available yet
Best value runtime is your biggest concern — this trimmer finishes the whole yard on one charge, especially for medium lots around a quarter-acre.
Skip if quiet needed you need precise edging cuts; the string-only edging works but lacks the guide wheel or blade depth control that dedicated edgers provide.
6. WORX WG163 12″ 2-in-1 Cordless Trimmer
The lightweight Worx with push-button line feed that keeps you moving.
This is the trimmer that over 28,000 owners have put to the test, and the consensus is clear: it is lightweight, easy to use, and a great value for regular yard maintenance. The 2-in-1 design converts from a string trimmer to an edger by tilting the head 90 degrees, and the rubberized support wheels guide you along driveways for straighter lines. The Command Feed spool system lets you advance fresh line by pushing a button — no bumping, no threading.
At 5.5 pounds with two 2.0Ah batteries included, the WG163 is well-suited for homeowners who want to finish trimming and edging in one session without gas or cords. Customers note the batteries last 20-30 minutes each, which covers a typical small-to-medium yard. The 0.065-inch line cuts cleanly through grass and light weeds, and the adjustable spacer guard protects flowers and garden features. The WORX PowerShare platform means the batteries also run other WORX tools.
The main limitation is runtime per battery — the 2.0Ah packs are fine for maintenance but won’t handle heavy overgrowth or a very large lot on a single charge. A few owners also note the batteries can be tight to remove from the charger. But the value is undeniable: two batteries, a charger, and a free-spool-for-life program make this the most budget-friendly entry point that still delivers reliable results.
Compact 2-in-1: What wins people over is the simplicity — light enough to carry one-handed, a button for line feed, and two batteries so you never pause mid-yard.
Short battery life: The honest trade-off — the 2.0Ah batteries run about 20-30 minutes each; if your yard takes longer, you will need the spare or a quick charge break.
Best small yard homeowners who want a reliable, no-fuss trimmer and edger for weekly maintenance on a standard suburban lot — the crowd favorite for a reason.
Skip for heavy use you frequently battle thick, tall weeds; the lighter motor and 0.065-inch line are designed for regular upkeep, not reclamation.
7. BLACK+DECKER MTC220 3-in-1 Trimmer, Edger & Mower
The 3-in-1 that trims, edges, and mows — all from one tool.
This BLACK+DECKER combo is built for apartment dwellers and small-yard owners who don’t have space for a full-size mower. The removable wheeled deck transforms the trimmer into a push mower that handles small lawns up to about 25×10 feet, according to owners. The trimmer and edger functions use the same PowerDrive transmission that prevents bogging in dense grass. The AFS automatic feed spool keeps the line advancing without stops.
The kit includes two LBXR2020 20V MAX batteries and a charger — reviewers point out about 20-30 minutes of runtime per battery, which covers the average small yard in one or two passes. The pivoting handle and adjustable deck height give you some ergonomic flexibility. At 9.9 pounds, it is heavier than a standalone trimmer but still manageable for carrying up apartment stairs or storing in a closet.
The mower function is the most divisive feature — some owners love it for tiny patches, while others find the deck misses flattened grass and requires vacuum-like pushing. The edging function is also a weak point for some: one owner called it “poor (just weed whacking, not clean).” This is best viewed as a trimmer-first tool with bonus mowing capability for the smallest spaces.
3-in-1 versatility
- Three functions in one compact footprint — trim, edge, and mow without storing multiple tools
- Two batteries included so you can swap and keep working
- Lightweight enough at 9.9 lb for apartment dwellers to carry and store
Underpowered mower
- Mower deck misses flattened grass and cuts unevenly on taller growth
- Edger is essentially the trimmer head tilted — not a dedicated blade edger
- Not suitable for lawns larger than a small patch (owners suggest under 25×10 ft)
Best all-in-one renters or apartment owners with a tiny yard who want one tool that trims the edges and mows the center without buying a separate mower.
Skip if mowing large your lawn is larger than a patio-sized patch or you expect a crisp, reel-mower-quality cut — the mower function is a trimmer on wheels, not a replacement for a walk-behind mower.
8. EWORK 2-in-1 Cordless 20V 12″ Weed Wacker & Edger
The 4.2-pound trimmer that is lighter than most cordless drills.
At just 4.2 pounds, this EWORK is the lightest trimmer in the roundup — a full 1.5 pounds lighter than the BLACK+DECKER LST522 and 4.5 pounds lighter than the WORX models. That weight difference matters when you are trimming for 30 minutes straight, and several owners note the trimmer is “lightweight, easy to handle” specifically for seniors and smaller-framed users. The 2-in-1 design converts from trimmer to edger by pressing a button and pivoting the head 90 degrees.
The kit includes two 20V 2.0Ah batteries and a charger, plus six replacement spool lines, so you are stocked for a full season. The auto-feed system advances the 0.055-inch line automatically as it wears — no bumping, no button pushing. The telescoping shaft and multi-angle rotating handle let you adjust the length and angle for a comfortable stance. The 12-inch cutting diameter and 9,000 rpm motor handle medium-duty yard work well, and owners confirm the batteries last through an entire yard on one swap.
The honest limitation is power — the motor is noticeable weaker than the 56V EGO models or even the 20V Craftsman, and the line can catch in the plastic guide groove on occasion. One owner called it “ok” and noted the power is “a little weak.” This is a tool for regular maintenance trimming on a small property, not for thick overgrowth or heavy brush. But “for the price, you get your money’s worth,” as owners put it.
Low price point: What wins people over is the featherlight 4.2-pound build — owners say it reduces arm fatigue so much that seniors and women who struggle with heavier trimmers can use it comfortably.
Weak motor: The honest trade-off — the 9,000 rpm motor lacks the torque for thick weeds or heavy overgrowth; stick to weekly maintenance and you will be happy.
Best cheap weight is your primary concern — 4.2 pounds, auto-feed line, and an adjustable shaft make this the most comfortable option for light trimming and edging.
Skip for thick weeds you regularly tackle tall, dense weeds or have a large property; the motor and line diameter are best suited to small yards and light work.
9. Jmmyvanee 8-Inch Cordless Weed Wacker with Wheels
The trimmer that swaps blades to slice through small branches.
Most string trimmers stop at grass and light weeds — this one includes three blade types that expand the job list. The plastic blades handle soft lawns, the metal blades cut grass and small shrubs, and the manganese steel circular saw blade chews through thicker branches. The rotating head adjusts 0-90 degrees both horizontally and vertically, so you can reach under bushes and along complex terrain. The package includes 20 plastic blades, 2 metal blades, and 1 circular saw blade.
The dual 21V 2000mAh batteries provide up to 40-60 minutes of combined runtime with a 2-hour charge time. The detachable wheels help guide the head along edges and reduce the effort of pushing through thicker growth. Owners praise the lightweight build — just 5.2 pounds — and note the “battery lasts long enough for my yard” and the wheels “help a lot.” The safety lock button prevents accidental starts, and the protective baffle blocks flying debris.
One owner reported the wheels and handles can slide off during use, and the battery life didn’t meet the advertised 40-60 minutes in their experience. The build quality at this price point is functional but not premium — treat the wheels as a helpful guide rather than a permanent fixture, and check the screws occasionally. But for a backyard that mixes grass, shrubs, and the odd woody stem, the blade versatility is a real advantage over string-only trimmers.
Unique wheeled design
- Three blade types (plastic, metal, circular saw) handle grass to small branches
- Head pivots 0-90° in both directions for hard-to-reach spots
- Lightweight at 5.2 lb with detachable wheels for guided edging
Narrow cutting path
- Wheels and handles may loosen during use; check and tighten regularly
- Runtime is adequate but some owners found it shorter than advertised
- Bare-bones build — no premium feel, just functional parts
Best for elderly mixed-yard maintenance where you need one tool that handles grass, light brush, and occasional woody stems without switching machines.
Skip for speed you want a polished, low-maintenance experience — the wheels need occasional tightening and the build is serviceable, not refined.
Understanding the Specs
Cutting Width & Line Diameter
The cutting width (measured in inches) tells you how much grass you clear in a single swing. A 12-inch head is standard for most yards; a 16-inch head like the EGO MHC1603 covers 33% more ground per pass. The line diameter is equally important — thinner 0.065-inch line is fine for light weekly trimming, while thicker 0.095-inch line (like the EGO MHC1502 uses) powers through dense weeds without snapping. If you regularly cut tall or thick growth, go with a thicker line and a motor that can spin it.
Battery Voltage & Amp-Hours (Ah)
Voltage (20V, 56V) determines how much power the motor can deliver — higher voltage generally means more torque for thick grass. Amp-hours (Ah) tells you the energy capacity: a 2.0Ah battery may run 15-25 minutes, while a 5.0Ah pack can run 45 minutes or more. Most kits include one or two batteries; two batteries let you swap and keep working without waiting for a charge. If your yard takes more than 30 minutes of trimming, look for a kit with two batteries or a 4.0Ah+ single battery.

Final Thoughts: The Verdict
For most homeowners, the electric string trimmer and edger that delivers the best mix of cutting width, battery runtime, and pro-grade edging is the EGO MHC1603 Multi-Head Combo Kit — its 16-inch cut, POWERLOAD spool, and carbon-fiber edger with depth control set a standard that few others match. If you want a lighter, budget-friendly option that still edges on wheels, grab the BLACK+DECKER LST522. And for the longest single-charge runtime in the roundup, the CRAFTSMAN V20 CMCST901M1 runs up to 63 minutes and covers a medium yard without stopping.
