Featuring a bright LCD display that shows you real time charging and a USB port for external devices, the UM20 is more than just your average charger. Designed for optimal heat dissipation and constructed from fire retardant materials, the UM20 is a safe device that will charge your batteries to completion and cut off power to ensure the best battery longevity. The intelligent charging program prioritizes charging process based on user preference and battery capacity.
