Nitecore UM20 USB Li-ion Battery Charger
Similar to the Nitecore UM10
, the Nitecore UM20 USB Charger
is an intelligent and multi-functional, single cell battery charger. It is capable of charging a wide range of li-ion batteries and it intelligently detects the amount of power needed to charge the battery. It also has USB input and output ports, which means you can charge an electronic device (through the USB cable) and a battery at the same time. With a high power adapter, you can simultaneously charge both the electronic device and the battery. With a low power adapter, you can prioritize charging to the battery or the electronic first.
most eye-catching feature is the LCD display, which shows the charging status and battery level. The internal circuits are also impressive, as it will stop charging immediately when it detects that a battery has been inserted wrongly. It will also stop charging the battery upon completion, which reduces the damage to the battery life. The charger can also charge 2 batteries independently. If one battery is wrongly inserted or there is something wrong with the battery, the charger will stop the malfunctioning slot only while the other continues charging.
The body of the charger is made of fire retardant materials and designed for optimal heat dissipation, so you can be sure that safety is of the highest priority when Nitecore
designed this product for you.
