Add a dedicated app to unlock additional features, and you've got the most advanced charger available today. Super simple. Super smart. Simply CS ONE.
APTO™ technology automatically recognizes the type of battery you're using, then automatically provides a customized charging program, telling you how quickly the battery is charged and ready to go.
