This NRG Cigarette Plug Adapter Cord is a 6' coiled power adapter that allows Canon camcorders using BP-77 and BP-718 batteries (e.g. Canon L1, L2, LX-100 and A1 Digital) receive power from a cigarette lighter receptacle, such as one found in an automobile. It converts 9-15VDC to regulated 6VDC camera input. This is the ideal accessory for documenting long car trips, allowing you to save the camcorder's batteries for other locations.
