The Nitecore UM20 USB Battery Charger is just like its smaller brother, the UM10, but has double of the battery charging capacity! And, like the UM10, won’t only charge your batteries, it’ll refuel your favourite electronic device too!
Micro USB input means you can charge your batteries off your computer or a power adapter. USB out means you can charge your iPad, smartphone, or even headlamp while you’re charging your batteries. The USB/battery switch at the top of the device allows you to prioritise which you juice up first.
The ABS fire retardant construction along with worldwide insurance gives you piece of mind that your batteries and devices will be safe as they charge.
