This NRG Cigarette Plug Adapter Cord is a 6' coiled power adapter that allows Canon camcorders using the BP-927 battery or DC-900 coupler (e.g. Canon XL-1s), receive power from a cigarette lighter receptacle, such as one found in an automobile. Its high-efficiency internal power converter accepts inputs from 9 to 16 volts. This is the ideal accessory for documenting long car trips, allowing you to save the camcorder's batteries for other locations.
