Applications: Perfect for maintaining batteries on motorcycles that use heated gear from "Warm & Safe Heated Gear." Since the barrel plug adapter is exactly the same and the 800mA maximum charging current is safe for the adapter's fuse you can plug the charger into the power socket on the motorcycle and maintain the battery accurately overwinter. It doesn't have enough power to run the heated clothing directly, however.
