Nitecore UI2 Portable Dual-Slot USB Li-ion Battery Charger

Optimal Charging Currents

The Nitecore UI2 is a dual-slot USB Li-ion battery charger that will quickly and easily bring life back to precious Li-ion batteries for all of your devices. With a max charging current of 800mA, it is easy to charge up batteries with over 2.9 volts of power. Simply insert the battery and Standard Mode will be activated. On the other hand, batteries with below 2.9V will automatically access Low Current Charging Mode which has a current of 100mA.

Charging Safeguards

With charging safeguards in place, it is easier than ever to leave your batteries to charge up without worry of overheating or overcharging. Anti-short circuiting and reverse polarity protections prevent a battery improperly inserted or short circuited from being charged – instead an error message will flash on the LED indicator. Ultimately saving the charger and the batteries from any harm.

Designed for Portability

Designed to be powered by a USB cable, the Nitecore UI2 is designed to, utlimately, be a portable charger. The micro-USB cord is compatible with USB adapters, power banks, or can easily be input into a computer if you’re staying put. The size of the charger also lends itself to being a portable product, with less than 5″ of length and weight less than 3 ounces, it is easy to travel with in a backpack or pocket. Never have your batteries die without a charger readily available again!
