This 12A fast charger has the highest charge rate in DeWalt's 20V MAX and FLEXVOLT lithium-ion battery range, minimizing downtime on the jobsite. The new Stage 1 and Stage 2 LED indicators communicate more about the batteries state of charge: the Stage 1 LED blinks until the battery is approximately 80% charged, then stays solid and the Stage 2 LED blinks until the battery is fully charged. Double insulated with an integrated fan-assisted cooling system for faster charge times and reduced delays from hot or cold battery packs. Wall mountable.
