Einhell GE-CT 18 Li Review
A light 18V trimmer with a 24 cm cut and plastic knives instead of line, plus a head that rotates for edging — cheap to buy but sold bare and limited to grass.
In short:The Einhell GE-CT 18 Li is a light 18V Power X-Change cordless grass trimmer with a 24 cm cut that uses plastic knives rather than nylon line (20 spares are stored in the handle). Its motor head rotates ±90° for edging and tilts to five positions for corners and under shrubs, with a telescopic shaft, adjustable auxiliary handle and a flower guard. It is sold without battery or charger. It suits small lawns and edges, not scrub.

What the listing confirms
Einhell’s Amazon.co.uk listing describes a 24 cm cut at a listed 8,500 rpm using plastic knives — 20 are supplied, kept in a storage compartment on the auxiliary handle. The motor head rotates ±90° for edging and tilts to five positions for corners and under hedges, the shaft is telescopic, the auxiliary handle adjusts and has a soft grip, and a flower guard protects border plants. It’s supplied without battery or charger; the listing gives an item weight of 3.97 lb (about 1.8 kg).
What it’s good at
The GE-CT 18 Li is built for one job: keeping a small, already-tidy lawn looking neat. It’s noticeably light in the hand, so it’s easy to hold out at an angle for long stretches of edging along paths, fences or flower beds. The 24 cm head threads into tight corners and gaps around obstacles more easily than a wider trimmer, and the rotating head turns it into an edger in seconds.
Plastic knives are its other quirk: there’s no line to wind or jam, you simply clip in a fresh knife when one wears.
Where it falls short
It’s sold bare, so the advertised price doesn’t include a battery or charger. It’s also a grass tool only — brambles, tough weeds and young saplings are off the table (the difference is explained in brush cutter vs strimmer). And the 24 cm width means more back-and-forth if your lawn or verges run to any real size.
Who should buy it
Someone with a small garden or a handful of edges to tidy, particularly if they already have Einhell 18V batteries. For overgrown plots or woody stems, a machine with a blade will be far less frustrating — Einhell’s own Agillo 18/200 runs on the same batteries.
Verdict
Light, simple and inexpensive, the GE-CT 18 Li is a good small-garden edger — factor in battery costs and don’t expect it to handle anything tougher than grass.
A cheap, light way into cordless trimming for small lawns and tidy edges, with a genuinely handy rotating head — but strictly a grass tool.
Einhell GE-CT 18 Li — frequently asked questions
Does the Einhell GE-CT 18 Li come with a battery?
No. It's supplied without battery and charger, so you need an 18V Power X-Change battery and charger. It's the cheapest way in if you already own Einhell 18V tools; otherwise factor in the extra cost.
Does it use line or blades?
Plastic knives. They clip into the head and are swapped when worn — the listing includes 20 of them, stored in a compartment on the auxiliary handle. There's no line to wind, but there's also no metal blade option.
Is it powerful enough for a medium or overgrown garden?
Not really. With a 24 cm cut it's sized for small, regularly maintained lawns. For bigger plots or neglected growth, a 36V or petrol brush cutter with a blade option will cope far better — see the best cordless brush cutters.
