Bad design: Some of PD power supplies are dangerous

    Xiaomi GaN Type-C 65W, one of adapters with issue.

    Some of PD adapters (if not most of them) have special small firmware that is being written via usual USB-C port they have.

    It also define voltages and other stuff.

    Issue is that some adapters allow reprogramming this by writing new firmware via computer using same USB-C cable.

    Such way voltages can be changed and adapter will be able to fry equipment as it will supply wrong, higher voltage, to device.
