The single-bay UM10 USB Management and Lithium-Ion Battery Charging System from Nitecore is a versatile USB-powered charger for lithium-ion and IMR batteries. An intelligent power management system automatically detects the input power, evenly distributes charging power, and selects the appropriate charging current based on the battery installed in the bay. Besides charging batteries, this charger also provides output power from a standard USB port, enables data transfer throughput via the USB and micro-USB ports, and features an integrated USB cable winder. An integrated LCD screen clearly displays the charging status, battery power level, and output selection. Reverse polarity and over-charge protection prevents damage to the battery if it's installed incorrectly or left in the charger after charging is complete.
