- Ready Stocks in Malaysia
- 100% Original: Nitecore UM2 UM4
- 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 ofo 1,500 mA. With LCD dispaly for real-time charging infomation, it is equipped with a USB charging port for outdoor
- Nitecore UM4 is a universal smart 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 UM2's four microcomputer-controlled charging slots then monitors and charges the battery independently.
- An integrated digital LCD screen clearly displays charging progress, voltage, current while an intelligent automatic power-off function terminates current when charging is complete. The Nitecore UM4: The world's most advanced fully-automatic digital charger. It's as simple as insert, detect and charge.
- Capable of charging 2 batteries simultaneously (depends on the size of your battery)
- Optimized charging design for IMR batteries
