What are the charging requirements for batteries with charging ports?
Fenix Direct Charge batteries can only charge under certain parameters, We recommend using a single port charger that is around 2 Amps with no more than 10 watts max. Most multi port chargers will not work, this includes computer ports. This is due to interference with the safety circuit in the battery. Samsung and LG are great choices, Apple and Anker for the most part are not.
