In ambulances and other emergency vehicles which carry electrical medical equipment, it is necessary to periodically charge the batteries of the equipment. This is usually done when the vehicle is parked using an extension cord to plug into a wall receptacle proximate the parked vehicle, and a separate battery charger where the equipment has none. This requires either that one extension cord be provided for each piece of equipment or that they be recharged one at a time. Typically the equipment is mounted by screws or bolts to the wall of the vehicle, and removal for replacement or repair is time consuming.
