THERM-IC POWERSOCK USB CHARGER FOR THERM-IC SOCK BATTERIES:
The charging element is a USB that connects to the charging port in the bottom of the battery and would connect to whatever standard wall mount you have for your smartphone. There's a little cube in the middle with two lights on it. When you plug in both batteries you will see red lights that means they are charging. When those red lights turn green that means your battery is fully charged and you are ready to get out there on the hill.
