The Vapcell SU2 charger charges two rechargeable Li-ion, Ni-Cd, or Ni-MH batteries and supports automatic or manual current adjustment from 50 mA to 5 A. In automatic mode, it detects the battery type and adjusts the charging current accordingly. The display shows information on voltage, internal resistance, charge level, capacity, and charging current.

It also supports LiFePO4 batteries and different charging voltages, which can be selected using the TYPE button. The USB output can be used to power portable devices, while the 50 mA low-current mode can activate batteries with very low voltage. It includes protection against reverse polarity, overcharging, overcurrent, overvoltage, overheating, and short circuits.
