A one of a kind compact yet powerful intelligent charger, the Nitecore UM2 smart charger delivers a maximum output of 3,000 mA through a QC USB input, allowing for quick and efficient charging of Li-ion cells. Offering the ability to use either a standard DC input or micro USB cable to recharge cells, the UM2 offers an incredibly smart charging platform thanks to the use of an optimized IMR battery charging program that monitors each of the dual battery bays independently throughout the charging cycle. An easy to read LCD screen displays all relevant information, which can be cycled through using the "V" button. The UM2 charger automatically selects the most optimal charging mode out of the three available (CC, CV, abd -dV/dt) based on the battery chemistry and capacity, and the "C" button allows the user to switch between 3.2V, 4.2V, and 4.3V charging modes. A power saving function in the form of an automatic dimming screen also makes its way into the Nitecore UM2, and the entirety of the chassis is constructed of durable, fire retardant polycarbonate material. A compact intelligent charger more than capable of keeping up with the competition, the Nitecore UM2 delivers a stable and efficient charging platform perfect for anyone limited on space at a budget friendly price.
