Abstract
An adapter plug system connectable to AC and DC sources for powering an electrically powered device. The system includes an adapter power cord for translating AC or DC voltages into a predefined DC voltage and a DC adapter. The adapter power cord also includes an adapter circuit in a case that translates a received voltage into a voltage acceptable for an attached electrically powered device. The adapter power cord includes a switch for automatically or manually setting the adapter circuit to translate AC or DC voltages. The system also includes a DC adapter that inserts into a vehicle lighter outlet for supplying a DC voltage to plug prong receiving ports.
