Good to know

The charger is powered via a standard USB-C connection, so you can use a compatible USB power adapter or power bank (not included) for flexible charging options. The compact black housing fits easily on a desk or in a drawer, and the intuitive LCD makes operation straightforward. Note that AAA Li-Ion batteries typically have a nominal voltage of 1.5V, but the charger outputs 4.2V for Li-Ion; ensure you use compatible batteries as specified by the manufacturer.
