UM2 2-SLOT CHARGER - NITECORE

UM2 2-Bay Charger - Nitecore

The Nitecore UM2 combines two independent bays with a detailed LCD screen to monitor the voltage, current, and progress of each battery. It is suitable for users who want more information than a charger with simple indicator lights.

Its total power can reach 3,000 mA with a compatible power supply, and the QC 2.0 input allows for faster charging depending on the setup. Thermal regulation and a dedicated program for IMR cells contribute to better-controlled use.

Safety tips

Inspect the insulating wrap before each use, respect polarity, and place the charger on a stable surface. Do not use a damaged battery and do not leave charging unattended for extended periods.

For more precise monitoring of a pair of batteries

The UM2 stands out from models with simple indicator lights thanks to a screen that makes the session more readable. It is aimed at users who want to observe voltage, current, and progress without moving to a four-bay station. The two independent channels make it easy to recharge a pair, but also to separately control different compatible cells. Use the displayed information as a guide: if a battery consistently behaves very differently, inspect it and compare its age rather than continuing cycles without checking.
