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.

When there is a power deficit for the UM20 to charge both the battery and USB device simultaneously, the UM20 will prioritize the charging of the battery or the device following the user’s preference.
A. When the top switch is set to BATTERY, battery priority mode will be activated. In this mode, the UM20 will charge the battery first. When the battery is fully charged or removed, the UM20 will then charge / power the USB device automatically.
B. When the top switch is set to USB, USB priority mode will be activated. In this mode, the UM20 will charge / power the USB device first. When the USB device is fully charged or disconnected, the UM20 will charge the battery automatically.
NOTE: A small electrical current will keep passing through to the external device connected to maintain the device in its full power state when it is charged.
