Fenix Battery Chargers
Smart chargers designed for the rechargeable lithium-ion cells used in Fenix flashlights and headlamps — primarily 18650, 21700, and 16340 sizes. A good charger protects your batteries and extends their lifespan.
Smart charging for lithium-ion
Fenix chargers monitor voltage, prevent overcharge, and detect faulty cells. They use USB-C input for convenient power and include LCD or LED indicators showing charge status per bay. For topping up a single cell while travelling, compact single-bay models are practical.
Single-bay versus multi-bay
If you carry multiple lights or rotate batteries, a multi-bay charger is a practical investment — many also function as USB power banks for charging phones and other devices. For the actual cells, see our rechargeable batteries page. Manufacturer-matched batteries and chargers deliver the rated output and runtime your lights were designed for.
