5 Cordless Electric Lawn Mowers

Why you should trust this guide

I research lawn and garden gear the same way I’d shop for it myself, by reading the manufacturer’s stated specs closely, comparing them across competing models, and flagging the places where the marketing language quietly omits something a buyer would want to know. For this guide I focused on five cordless electric mowers that sit in overlapping price and yard-size brackets, so the comparison is apples to apples rather than a grab bag of unrelated machines. Every claim about deck size, battery, or feature set in the sections below traces back to what each maker publishes for that product.

I also try to be honest about who each mower is not for. A 14-inch deck and a 30-minute runtime are perfect for a courtyard lawn and frustrating for a half-acre, and I say so plainly. Where a spec is genuinely useful (a single-lever height adjuster, a battery that doubles as a power bank, a true 4-in-1 deck) I call it out, and where a number deserves caution (short runtimes, brushed versus brushless motors, single batteries) I do the same. The goal is a guide that helps you match a mower to your actual yard, not one that pushes the most expensive box.

How we researched

My evaluation here is research-based rather than a turf trial, so I want to be upfront about that. I compared each mower across the criteria that decide whether a cordless machine is pleasant to own: deck width and how it maps to yard size, the cutting system (mulch, bag, side discharge, or some combination), height-adjustment design, motor type, battery capacity and stated runtime, weight and maneuverability, and any safety or convenience extras such as headlights, power-bank functions, or bundled tools. I weighted the factors that owners complain about most, runtime and weight, more heavily than headline features.

For each product I read the manufacturer’s listed features, then cross-checked them against the other four to see which model leads on a given axis and which one trails. I treated every number, like a 30-minute runtime or a 21-inch deck, as the maker’s stated figure, not something I clocked myself. When two mowers claimed similar specs, I looked at the supporting details (number of batteries, brushless versus brushed motor, number of cutting positions) to break the tie. That is how I arrived at the use-case picks in the takeaways and the verdict.

Greenworks 40V 16″

This is the pick I’d hand to most people with a small or mid-sized lawn. Greenworks describes it as an ultra-lightweight 16-inch mower with a single-lever height adjustment, which is the detail that matters most in daily use, because changing cutting height on one lever beats fiddling with four separate wheel clips every time the grass condition changes. The deck runs a 2-in-1 system, so you can mulch clippings back into the lawn or bag them, and Greenworks calls the motor and drivetrain maintenance-free, meaning no oil, no spark plugs, and no pull cord.

The 16-inch deck is the sweet spot of this group: wide enough to finish a typical suburban lawn without endless passes, yet narrow and light enough to turn around flower beds and store on end in a garage. Going cordless and gas-free also removes the two chores people hate most, fuel mixing and winterizing.

The honest trade-off is reach. A 2-in-1 deck means you get mulch and bag but not the side-discharge or leaf-collection modes that the 60V and 48V models in this guide add, and at 16 inches it will take noticeably more passes on a big lawn than a 21-inch self-propelled mower. The listing also leans on “ultra lightweight” and “maintenance free” without publishing a runtime figure here, so if battery life is your top concern, confirm the included pack’s amp-hours before you buy.

Litheli 14 Inch Cordless Lawn Mower

If your priority is mowing without waking the neighbors, the Litheli 14 Inch is the one I’d point you to. Litheli builds it around a whisper-quiet brushless motor with zero scheduled maintenance, and pairs that with a 1-lever, 5-position height adjuster so you can adapt the cut by season and skip the raking by mulching. It is aimed squarely at small to mid-sized yards as a lighter, simpler alternative to a gas engine and a tangle of cords.

The standout feature is the 5.0Ah battery, which Litheli says doubles as a power bank, so the same pack that runs the mower can charge a phone or other devices. Combined with the lightweight, ergonomic frame and compact storage footprint, this is a genuinely easy mower to carry, push, and tuck away in a small shed or apartment-sized garage.

The catch is runtime and deck width. Litheli rates the pack at up to 30 minutes of fade-free power, and that is on a single 5.0Ah battery driving a 14-inch deck, the narrowest in this guide. For a courtyard or a small front lawn that is plenty, but on anything approaching a quarter-acre you will either run out of charge mid-job or spend a long time on narrow passes. Treat this as a small-yard specialist, not a do-everything mower.

KOMASTY 40V Electric Lawn Mower 15″ Cordless Battery Powered

The KOMASTY 40V is the value play of the group because of one detail: it ships with two 4.0Ah batteries rather than one. That gives you a hot spare so you can keep mowing while the second pack charges, and KOMASTY backs it with fast charging to shorten the wait. The 15-inch deck slots neatly between the Litheli’s 14 inches and the Greenworks 16, making it a sensible mid-sized-yard choice.

Feature-wise it covers the basics well. A high-efficiency brushless motor drives the blade, the deck offers both mulching and bagging so you can customize your routine, and there are 5 adjustable cutting positions for an even finish across different grass heights. KOMASTY also includes a dual-action safety switch that requires two deliberate actions to start, which is a reassuring touch on a powered blade, and the company says assembly is straightforward out of the box.

The trade-off is the same runtime ceiling that limits most mowers this size: KOMASTY rates the two batteries at up to 30 minutes of combined runtime, so the second pack extends your session rather than doubling it dramatically, and you will still be swapping batteries on a large lawn. KOMASTY is also a less familiar brand than Greenworks, so factor in how easily you can source replacement blades or batteries down the road before committing.

Greenworks 60V 21″ Brushless

For a larger lawn, this is the mower in the guide I’d choose. Greenworks steps up to a 21-inch brushless, battery-powered deck with effortless self-propelled control, so the mower drives itself forward and you steer rather than push, which makes a real difference on a bigger or sloped yard. It is described as quiet and maintenance-free, with an LED headlight for low-light mowing and 4-in-1 versatility covering mulch, bag, and additional discharge modes.

The 21-inch deck is the widest here, so each pass clears far more grass than the 14, 15, and 16-inch models, and self-propulsion removes the fatigue of pushing a heavier machine across a long lawn. Greenworks also pitches this as a complete ecosystem value, with the battery, fast charger, and grass-handling accessories included in the kit, and the 60V battery platform is shared across the brand’s larger tools, so a pack you buy here can power other Greenworks equipment.

The honest downside is that all of this adds weight and bulk. A self-propelled 21-inch mower is heavier to lift, harder to store on end, and more machine than a tiny lawn ever needs, so the Litheli or the 40V Greenworks remains the smarter buy for a courtyard. The listing also emphasizes the ecosystem and features without a published runtime figure, so verify the included 60V pack’s amp-hours against the size of your yard before you rely on a single charge to finish.

Greenworks 48V

The Greenworks 48V is the pick if you want a mower and a couple of yard tools in one purchase. Greenworks builds this as a combo kit that unites a self-propelled 21-inch mower, a 12-inch string trimmer, and a blower, all running on the same 48V (24V x 2) battery platform. The kit includes two 5Ah batteries and a dual-port charger, so you can charge both packs at once and rotate them across the three tools.

For someone setting up a cordless yard kit from scratch, the value is in the bundle. The mower itself is self-propelled with a 21-inch deck, the string trimmer cuts a 12-inch path with a brushless motor for edges and borders, and the blower (a brushed motor) is rated at 320CFM at 90MPH for clearing clippings and leaves. Sharing one battery system across mower, trimmer, and blower means fewer chargers and fewer one-off packs cluttering the shelf.

The trade-off is that a combo kit is a set of compromises rather than three best-in-class tools. The blower uses a brushed motor, which is generally less efficient and shorter-lived than the brushless motors elsewhere in this lineup, and splitting two 5Ah batteries across three power-hungry tools means you will be managing charge carefully on a big day. If you only need a mower, the 60V 21″ is the more focused choice; the 48V earns its place specifically when you want the trimmer and blower in the same box.

What to look for

Before you pick a cordless mower, match these factors to your actual yard rather than to the longest spec sheet.

• Deck width versus yard size: 14 to 15 inches suits courtyards and small lawns, 16 inches covers typical suburban yards, and 21 inches earns its bulk only on larger or sloped lawns.
• Runtime and number of batteries: many of these mowers are rated around 30 minutes, so a second included pack (like the KOMASTY’s two batteries) matters more than headline voltage.
• Motor type: brushless motors (Litheli, KOMASTY, the Greenworks mowers) tend to run more efficiently and longer than brushed ones, such as the 48V kit’s blower.
• Self-propelled versus push: self-propulsion (60V and 48V) saves your back on big or hilly lawns but adds weight and storage bulk you do not want on a tiny yard.
• Cutting system: 2-in-1 means mulch and bag, while 4-in-1 adds discharge and collection modes for handling heavier growth and leaves.
• Height adjustment: a single-lever adjuster (Greenworks 40V, Litheli) is far quicker than per-wheel clips, especially across seasons.
• Extras worth having: an LED headlight for low light, a battery that doubles as a power bank, and a dual-action safety start each add real-world convenience or peace of mind.
• Battery ecosystem: staying on one voltage platform (40V, 48V, or 60V) lets a single pack power other tools you may add later.

The verdict

For most small to mid-sized lawns, the Greenworks 40V 16″ is the mower I’d buy first, thanks to its light weight, single-lever height adjust, and tidy maintenance-free 2-in-1 deck. If quiet matters most, the Litheli 14 Inch with its whisper-quiet brushless motor and power-bank battery is the better fit for a courtyard, while the KOMASTY 40V 15″ wins on value by including two batteries so you can keep mowing.

Scale up and the choices change. For a larger or sloped lawn, the self-propelled Greenworks 60V 21″ Brushless clears more ground per pass and adds an LED headlight and 4-in-1 versatility. And if you want to outfit a whole yard at once, the Greenworks 48V combo kit pairs a self-propelled mower with a string trimmer and a blower on one battery platform, as long as you accept that a bundle trades a little per-tool refinement for the convenience of buying everything together.
