The Buddy Buggy DC to AC Power Converter converts DC power received from the Buddy Buggy to AC power for your connected device. The unit comes with a power cord that plugs into the cigarette lighter/auxiliary port of the Buddy Buggy. The device's power cord is then plugged into the converter's AC port. This allows you to use the same wall plug-in that comes standard with your device to power it from the Buddy Buggy while off-roading.
