Nitecore UM20 LCD

The Nitecore UM20 is an advanced USB management and charging system capable of charging a single lithium-ion battery from a USB power source, while simultaneously charging an external device.

A high definition LCD displays real time charging status, accurate to 1%.

If a low power adapter is being used the UM20 has a priority switch that allows the user to select which to charge first, then automatically charging the second option when the first is complete.

Data can be transferred from a computer to the external USB device, even while charging is taking place.
