      The NITECORE UM4 is a QC input available intelligent USB four-slot charger with a total max output of 3,000 mA and a single slot max output of 1,500 mA and is capable of charging 4 batteries simultaneously and controlling each slot independently. It only takes 2 hours to charge 80% of a 3,500mAh battery.

      The LCD screen can display real-time information of Battery Health by “Good” or “Poor”, Internal Resistance, Charging Current, Battery Voltage, Charged Volume, and Charging time. It can enable automatic detection of battery power level and automatic selection of the appropriate voltage and charging mode and automatic selection between 3 charging modes (CC, CV, and -dV/dt). The charging parameters can be set manually to meet various charging needs.

      The specially designed Micro USB port is compatible with various mobile power sources, solar panels, and USB adaptors to ensure an endless power supply. UM4 incorporates an optimized IMR battery charging program, which is able to monitor the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the batteries. The UM4 is compatible with 3.6V/3.7V Li-ion rechargeable batteries, 3.8V Li-ion rechargeable batteries, 1.2V Ni-MH/Ni-Cd rechargeable batteries, and 3.2V LiFePO4 batteries.

      Multiple safeguards ensure the safe charging process, including automatic battery internal resistance detection, anti-short circuiting and reverse polarity protection, overtime charging protection, over-discharged Li-ion battery activation, and over-discharged IMR battery restoration. Apart from being constructed from durable and fire retardant PC materials, the built-in temperature regulation system is designed to prevent overheating and to ensure the stability of the charging process. If there is no action to the buttons or batteries in 3 minutes, the screen will automatically go dim to save energy.
