Pros
- Complete kit — battery and charger included
- Above-average 30 cm cut for 18V
- Tool-free switch to edging, with guide wheel
Cons
- Grass only — not for brush
- Amazon.co.uk listing is the continental (-QW) version
- Below pro brands on durability
The BLACK+DECKER STC1840EPC is a sensible, affordable lawn trimmer that arrives ready to use — a 4.0 Ah battery and charger are in the box, and the 30 cm cutting width is a little wider than many 18V rivals.
What the listing confirms
- Cut: 30 cm, with a listed 7,200 rpm and BLACK+DECKER’s E-Drive gearing for torque in long or wet grass.
- Runtime: up to 75 minutes from the 4.0 Ah battery, per the maker; variable speed lets you trade power for runtime.
- Line: PowerCommand EasyFeed — you press a button to release more line, rather than bumping the head.
- Edging: switches to edging without tools, with a guide wheel to run along the lawn edge.
The Amazon.co.uk listing we found in October 2026 was the STC1840EPC-QW, the continental version, sold by a third party; UK buyers should check the charger comes with a UK plug.
Who it’s for
Homeowners who want a cheap, complete cordless trimmer for grass and edging without buying batteries separately. It’s a consumer-grade tool for lawns — not a brush cutter, and not built for heavy or frequent professional use.
Verdict
Good value for a ready-to-go 18V lawn trimmer. Buy it for grass and simplicity; look to a blade machine for anything tougher — see the best cordless brush cutters, or the lighter STC1820 if your lawn is small.
A well-priced, ready-to-go 18V trimmer for lawns — the included 4.0 Ah battery and generous cut make it good value, if not a heavy-duty tool.
BLACK+DECKER STC1840EPC — frequently asked questions
Does the Black & Decker STC1840EPC include a battery?
Yes — the box contains the trimmer, an 18V 4.0 Ah lithium-ion battery, a charger and a line spool. BLACK+DECKER quotes up to 75 minutes of running time per charge, depending on the speed setting and the grass.
Can it cut brambles?
No — it's a grass trimmer for lawns and light growth, not a brush cutter. For woody growth you need a blade-equipped machine.
How wide does it cut?
30 cm, which is a little wider than many 18V trimmers, so it clears grass a touch faster.
