NiteCore - UM20 USB Charger


R 350.00

The NiteCore UM20 USB Battery Intellicharger!

The Nitecore 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 the UM20's microcomputer-controlled charging slot then monitors and charges the battery. 

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.
