1. A power supply interface for powering a data processing system using an output of a vehicle diagnostic port disposed on a vehicle, wherein the vehicle diagnostic port is configured to output self-diagnostic information, the interface comprising:

  • a first connector configured to detachably couple to the vehicle diagnostic port to receive output signals from the vehicle diagnostic port, wherein the output signals of the vehicle diagnostic port include a vehicle power output and a diagnostic output including self-diagnostic information;

    a second connector configured to detachably couple to a docking connector of the data processing system;

    a power converter, coupled to the first connector and the second connector, configured to generate a power supply signal based on the vehicle power output of the vehicle diagnostic port;

    wherein when the power supply interface couples to the vehicle diagnostic port via the first connector and to the docking connector of the data processing system via the second connector, the power supply interface supplies power to the data processing system using the power supply signal.
