Dead Li-ion cell in the torch, the drill, or that one gadget that refuses to share its charger? This little unit plugs into any USB source — power bank, laptop, car adapter — and fast-charges the cell without mains. Auto-detects what's in the cradle and sets 500mA or 1000mA accordingly. Handles everything from a tiny 10440 up to a 26650, and it'll even wake a zero-voltage protected cell that other chargers just ignore. Toss it in a kit bag and never hunt for a matching wall brick again
