Nitecore UM20 External Battery Charger

The Nitecore UM20 features a smart chip that automatically detects variables for maximum efficiency. The front-mounted LCD screen displays charging status in real time; power levels are easy to monitor. The Nitecore UM20 has two bays and two charging ports that allow you to charge two batteries and an external device simultaneously.

One of the most useful features of the Nitecore UM20 is the ability to choose charging priorities during low power situations. When there is enough input, the UM20 charges the battery and the external device together. When input is not sufficient, Priority Mode is activated and it charges the device you prefer. Another great aspect ot the Nitecore UM20 is that it automatically selects charging current based on battery parameters. The UM20 can also detect input power and channel power very effectively. Using the USB port at the back, you can also transfer data to/from your device while it is being charged. In terms of safety, the UM20 is made with fire-retardant ABS plastic and equipped with a reverse polarity protection system - it even has a dedicated cable winder at the back to put an end to cable clutter.
