ESMARTER Mini COB Keychain Flashlight – Compact, Bright & Always Ready

Meet your new go-to everyday carry light: the ESMARTER Mini COB Keychain Flashlight. Packing a powerful 800-lumen COB LED into a palm-sized body, this rechargeable flashlight clips right onto your keychain so you're never left in the dark — at the campsite, in the garage, during a power outage, or on the trail.

Key Features

800-Lumen COB LED: Super-bright, wide-angle illumination lights up a range of up to 50 metres — far more coverage than a traditional single-LED torch.
4 Lighting Modes: Switch between High, Low, Strobe, and SOS modes to match any situation, from reading a map to signalling for help.
Built-in Rechargeable Battery: USB charging means no more hunting for disposable batteries. Simply plug in, charge up, and go — battery included.
Magnetic Base: The integrated magnet snaps firmly onto any metal surface — tool boxes, car hoods, tent poles with metal stakes — for hands-free, directed lighting wherever you need it.
Waterproof ABS Body: CE-certified, splash-resistant construction handles rain, puddles, and rugged outdoor conditions without skipping a beat.
Ultra-Portable Keychain Design: Lightweight and compact, it attaches to your keys, backpack, or belt loop so it's always within reach. 5W power in a package that fits in your pocket.
