    This is literally what PD triggers do. They negotiate high power in place of the device, and dump it on Vbus without checking

        Powering a device that’s designed for a simple barrel jack or 12V battery from a type-c power supply.

        Most trigger devices I’ve seen have barrel jacks or positive and negative terminals as their output, so they don’t technically dump high voltage on Vbus, the output side isn’t USB.

        It lets you replace a wall wart with USB-C. I have a Bluetooth speaker which uses a 20 volt 2 amp wall plug which is fucking massive and eats up enough space for at least 3 outlets, regardless of the orientation of the plug. Now it’s just USB-C powered thanks to a $2 little circuit board, so I can use anything which outputs 20 volts. If I’m so inclined, I can even hook it up to a USB battery bank.

        I fukken love me a good USB PD trigger board.
