Nitecore UM4 is a QC input available universal intelligent USB four-slot charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The UM4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 batteries. Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the four microcomputer-controlled charging slots then monitors and charges the battery independently. Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current while an intelligent automatic power-off function terminates current when charging is complete. With a total max output of 3,000 mA and a single slot max output of 1,500 mA. With LCD display for real-time charging information, it is equipped with a USB charging port for outdoor.
