The Nebo Luxtreme Nano is a tiny USB-C rechargeable flashlight, here in blue, small enough for a key ring thanks to its built-in attachment hole. Despite its size it gives a 420 lumen Turbo mode with a beam of up to about 300 m, plus High (80 lumens, about 2 hours), Medium (40 lumens, 3.5 hours), Low (12 lumens, 8 hours) and Strobe. Smart Power Control, Direct-to-Low start-up, a power indicator and a charging indicator are built in. The anodised aircraft-grade aluminium body is IPX6 water resistant and 1 m drop resistant. It runs on an internal 300 mAh 3.7 V Li-ion battery that fully recharges in about 1.5 hours. It is about 85 mm long and 25 mm across and weighs about 36 g, so it disappears in a pocket, bag or glovebox. A USB charging cable is included.
