Nitecore UM10 / UM20 Battery Charger

Capable of charging Li-ion batteries and an external device simultaneously via USB, Nitecore's UM10 & UM20 are a welcome addition to their impressive charger family!

Boasting a convenient USB input and output charging, an intelligent charging circuit, easy-to-read LCD display, and construction made from ABS fire retardant materials, the UM Series of chargers are some of the most handy on the market! The intelligent charging circuit automatically stops charging upon charging completion meaning no more overcharging! It also adjust charging power based on the detected battery capacity!

The HD LCD display will clearly display battery power levels and the built-in reverse polarity protection will automatically put the charger in standby mode if you accidentally install a battery backwards! When input power is sufficient, the UM10/20 chargers will charge both an installed battery and a plugged in external device simultaneously. The charger also allows you to set either a battery or external device priority for when input power is not sufficient making it extremely versatile.

In addition to these great features, the UM10 & UM20 can act as an intermediary between two USB-connected devices, is designed for optimal heat dissipation (no overheating!), and is built to house either a 2.5mm or 3.0mm USB cable!
