A retractable external vehicle electric system includes a cord holder to be mounted inside a car's engine compartment, including a two-piece case, a spool rotatably disposed within the case for retractably holding a first electric cord, a reel shaft securing together th e case and serving as the axis about which the spool rotates, a spring wrapped about the shaft for automatically retracting the first electric cord once it is pulled away from the spool, structure for connectin g two electric cords together, and an automatic, temperature responsive switch for allowing electricity to flow from the first electric cord to a second electric cord when a car's engine compartmen t has an ambient temperature less than a predetermined temperature set within the switch, so that when electricity is permitted to flow to the second electric cord, it is capable of functioning as an electrical outlet. 18
