Abstract: A vehicle power adapter with locator system which integrates RF transmitter with power adapter and uses power adapter to provide power to the locator system includes a power adapter transmitter and an external receiver. By integrating RF transmitter with vehicle power adapter (VPA), power can be drawn from vehicle power sockets to provide power to RF transmitter to send personal identification number (PIN) code to the RF receiver. The RF receiver which takes in the RF signals and PIN code from the transmitter to locate and display the position of the car by display the information on the liquid crystal display (LCD). Furthermore, the locator may remain dormant until it senses the trigger event or until a user requests the location of the parked vehicle.
