Nitecore UM20 Charger
The world’s only USB and Li-Ion battery digital charger. Ideal for charging your phone and batteries at the same time while travelling.
The UM20 is compatible with Li-ion and IMR cylindrical rechargeable batteries only. Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the UM20’s two microcomputer-controlled charging slots then monitors and charges the battery independently.
An integrated digital LCD screen clearly displays charging progress while an intelligent automatic power-off function terminates current when charging is complete.
USB output charging and data transfer lets you work or charge your phone and battery at the same time, perfect for travellers working on laptops and at charging stations. A rear USB cable winder keeps everything neat and tidy.
