Einhell GE-CM 18/33 Li Review: Amazon's Bestselling Cordless Lawn Mower
The Einhell GE-CM 18/33 Li has spent long stretches as the number one lawn mower on Amazon Germany — a remarkable result for an 18V machine. Its success comes from an honest promise: for small urban lawns, it removes the cable, the petrol and most of the weight, at a starter-kit price.

What Stands Out
It starts instantly, makes little noise compared to petrol mowers, and folds compactly for shed or balcony storage. For a typical city garden — a strip of lawn behind a terraced house — it turns mowing from a chore requiring equipment into something closer to vacuuming.
The battery is the same Power X-Change unit as Einhell's drills and trimmers, which is a real cost saver if you grow into the system.
Where It Falls Short
The 33 cm deck and 18V motor set clear limits: tall, wet or neglected grass will slow it down, and lawns beyond roughly 200 m² mean battery swaps or waiting on the charger. For larger gardens Einhell's own 36V twin-battery models are the better fit.
Who Should Buy It?
Owners of small, regularly-mowed lawns who value low noise, zero cable management and easy storage. It is a poor match for meadows and large plots — and an excellent one for the small gardens most city households actually have.
FAQ
How much lawn can it mow per charge?
With a 4.0 Ah battery, roughly the recommended 200 m² in normal conditions. Thick or damp grass reduces this noticeably.
Does it mulch?
The standard version collects into the rear box; check the current package description for mulching accessories.
