Nitecore UMS4 USB quick charger

The UMS4 can charge Li-Ion, NiMH/NiCd, and LiFePO4 batteries. The charger automatically detects the battery type, assesses the battery condition and charge status, and selects the appropriate charging method. A standard charging current of 1000 mA is preset, but this can be manually increased up to 2000 mA depending on the battery type, and up to 3000 mA in QC mode. The maximum charging current for one occupied slot is 3000 mA, and when all four slots are occupied, it is 1000 mA per slot. It is powered via USB and can therefore be operated from any USB outlet.
