ABSTRACT:
The present invention provides an electrical adaptor for transmitting current from a standard seven prong trailer plug power source to a female cigarette lighter plug. The adaptor uses two of the seven prongs of the seven prong trailer plug power source to supply current to the female cigarette lighter plug. The electrical adaptor provides a way of using a standard trailer plug, normally located external to a vehicle, to supply electrical current to an accessory. The adaptor is contained within a cylindrical plastic housing. A thermal insulator is positioned around the female cigarette lighter plug to thermally insulate it from the cylindrical plastic housing.
