Product description The double-bay UM20 Battery Charging System from Nitecore is a versatile charger for lithium-ion and IMR batteries. An intelligent power management system automatically detects the number of batteries installed, evenly distributes charging power, and selects the appropriate charging current based on the specific needs of each battery installed. 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. A LCD screen clearly displays the charging status and power level of each battery, and output selection. Reverse polarity and over-charge protection prevents damage to the batteries if one or both are installed incorrectly or left in the charger after charging is complete. - Charging
