The Nitecore UM20 Charger is a super versatile battery charger with a host of amazing features. Not only can this device charge your vape batteries, but it also features a USB output to charge an additional external device. The handy Micro USB input means you can even connect an external device to your computer for data transfer.

The high definition LCD display shows charging progress accurate to 1%, so you can be assured your batteries will hold their power all day long. The reverse polarity protection feature will show “EE” on the display panel and terminate charge of any batteries installed the wrong way around. You don’t need to worry about leaving your batteries in the charger as the intelligent UM20 charger will automatically stop charging upon completion. The spring loaded slider enables charge of different sized batteries making this extremely versatile, no matter the batteries you require charging.

The Nitecore UM20 charger is very clever and has the ability to activate ‘priority mode’ when charging batteries and an external device simultaneously. The charger can prioritise either the batteries or external USB device when input power is not sufficient to charge both at the same time (for example use with a low power adapter). When used with a high power adapter you can charge both your batteries and external device simultaneously, keeping you charged up all day long! Tangled cables are a thing of the past with its handy rear USB cable winder and grooves to keep your cables neat and tidy.
