The LUC V6 is capable of charging all 6 bays at 0.68A which is more than enough power to charge vaping batteries which are generally charged at half an amp. However, if one wanted to charge at a faster rate, the LUC V6 can effectively charge two batteries at once at a lightning fast 2A per cell, pulling a max of 4 amps! The charger also has the functionality to charge USB devices with another included adapter. This charger has all the bells and whistles one could want from a charger.
