| Description: | The Nitecore UM2 is an intelligent USB charger with a total maximum output of 3000mA, offering speedy charging for your batteries. Please note, in order to achieve the maximum charging speed a 9V 2A QC 2.0 charging adapter must be used.
The charger features a charging programme specially optimised for IMR batteries which monitors the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the battery. Per single slot the UM2 has a maximum output of 1500mA, which means a 3500mAh 18650 battery takes approximately 2 hours to reach 80% charge.
