Nitecore UM4 USB Charger

NITECORE is launching its brand-new UM4, which is a QC input available intelligent USB-C four-slot charger with a total max output of 3,000 mA and a single slot max output of 1,500 mA. It is capable of charging 4 batteries simultaneously and controlling each slot independently.

• Speed: It only takes 2 hours to charge 80% of a 3,500mAh battery.

• Screen: The LCD screen displays real-time information: Battery Health ( Good or Poor ), Internal Resistance, Charging Current, Battery Voltage, Charged Volume, and Charging time.

• Compatibility: The charger is compatible with 3.6V/3.7V Li-ion, 3.8V Li-ion, 1.2V Ni-MH/Ni-Cd, and 3.2V LiFePO4 batteries.

• Automatic Control: Enables automatic detection of battery power level and automatic selection of the appropriate voltage and charging mode (CC, CV and -dV/dt). Charging parameters can also be set manually.

• USB-C Input: The USB-C port is compatible with various mobile power sources, solar panels, and USB adaptors to ensure endless power supply.

• Safeguards: Multiple safeguards ensure safe charging: automatic battery internal resistance detection, anti-short circuiting and reverse polarity protection, and protection against overheating.
