ZJS Cordless Grass Strimmer 21V – 2x 4.0Ah Batteries & 25 Blades

This cordless strimmer from ZJS is a versatile tool that handles far more than just tidying up lawn edges. Powered by an 850W copper motor running at up to 18,000rpm, it comes with three different blade types — plastic blades for soft grass, stainless steel blades for tougher weeds and reeds, and a circular saw blade for thicker woody growth — so you can switch between light trimming and more demanding clearance work without needing separate tools. The blades are straightforward to swap out, and the whole package arrives with everything you need to get started, including protective glasses and gloves.

Two 4.0Ah batteries are included in the box, giving you a genuine runtime of one to two hours depending on what you're cutting through. That's a practical amount of working time for most garden sessions, and a full recharge takes around three hours, so you can top up one battery while using the other. The detachable battery design keeps things simple, and the fast charging means downtime is kept to a minimum.

At under two kilograms, this strimmer is light enough to use comfortably for extended periods, making it a sensible choice for older gardeners or anyone who finds heavier petrol tools tiring. The telescopic pole adjusts between 95 and 125cm to suit your height, the cutting head tilts up to 90 degrees for awkward angles and slopes, and a set of removable wheels helps you guide it smoothly along borders and edges. The dual-switch safety start is a thoughtful touch that reduces the risk of accidental activation.
