USB Charger UM10-Nitecore Best

UM chargers from Nitecore are not only extremely compact and space-saving, but also highly versatile. The unit is not only able to charge one Li-Ion rechargeable battery, but also an additional USB device such as mobile phone with a separate USB port. The charging priority can also be selected if the electrical energy supply is insufficient for concurrent charging due to a weaker power supply unit. Accordingly, either the inserted rechargeable battery can be charged first, or the connected USB device; the unit switches over automatically. Usable at any USB interface on a computer or in the car, or with USB power supply (not included) on any power outlet. Backlit LCD display, reverse polarity protection. Cable compartment in the housing. Compatible with Li-Ion/IMR: 18650, 18490, 18350, 17670, 17500, 16340 (RCR123), 14500, 10440
