The BU2 is a smart USB charger, which is compatible with most cylindrical rechargeable batteries on the market. The integrated 2A charging port is fast charge capable.
The BU2’s USB output function allows the charger to be used as an external charging station whilst the automatic detection system can detect Li-ion, Ni-MH and Ni-Cd batteries as well as selecting the best charging mode for each battery. The BU2 has three LED display lights, which clearly display the current charging operations.
