Nitecore UM4 Charger

The Nitecore UM4 charger is an advanced charger that allows simultaneous charging of four cylindrical batteries of different sizes, making it an ideal tool for professional users.

With a maximum output current per socket of up to 1.5A and compatibility with various battery types such as Li-ion, IMR, Ni-Mh and Ni-Cd, it provides fast and versatile charging.

The Nitecore UM4 battery charger has a large and easy-to-read LCD display for battery charging status and a built-in Micro-USB fast charging port, making operation even more convenient and efficient.

Charging time for the 3500 mAh battery to 80% is about 2 hours (when connected to the QC adapter), and the optimized IMR battery charging program guarantees optimal performance.

Intelligent battery type detection, manual settings, a reactivation function for over-discharged batteries, and protection against overload, short circuit and reverse polarity make the Nitecore UM4 charger not only a practical, but also a safe tool.

With intelligent temperature control, cooling fins, a flame-resistant polycarbonate housing and RoHS, CE, FCC and CEC certifications, it meets the highest industry standards.
