ABSTRACT:
A dual-voltage electric hair curling apparatus includes a having a handle and a heated barrel. A pair of positive temperature coefficient (PTC) heating elements are located in the barrel and are operable, respectively, at a low automotive vehicle voltage and a high domestic voltage. A switch in the handle permits energization of either heating element dependent upon the voltage of the available power supply and an overload fuse prevents damage to the low voltage heater should it be accidently energized from a high voltage supply. The curler is provided with a power cord terminating in a two-pronged plug receivable into a corresponding receptable on a portable vanity case adapted to be mounted by clips to the visor of an automotive vehicle. The vanity case has a mirror illuminated by electric luminaires on its front surface and a cord set terminating in a plug receivable in an automobile cigar lighter is connected to the receptable and luminaires. When not in use the hair curler, power cord and cord set are stored in a compartment in the vanity.
