The Nitecore UM20 is an advanced USB management and charging system capable of charging two lithium-ion batteries from a USB power source, while simultaneously charging an external device.
A high definition LCD displays real time charging status, accurate to 1%.
When used with a high power adapter the UM20 will charge the inserted batteries plus an external device (such as a mobile phone) simultaneously. 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.
