    I can’t stand these USBC cords and now these USBC flash drives are a thing. They end up being a 2-n-1 or you gotta buy ANOTHER adapter for the USBC or whatever needs to be attach to it in order to work. Its just more money for extra work. 😮‍💨😑😑😑

    i found a power adapter in my closet last week that had it’s barrel jack cut off and instead had two wires exposed and had “works for fans” labeled on it lol… no idea why I did that

      That’s kinda what I did to use a computer fan as a normal fan. I got one of these power adapters that let you pick a voltage, cut off the plug at the end of the cable, cut off the plug on the fan’s cable, and connected the two. Maybe that’s a dumb way to do it, but it’s about as expensive and definitely quieter than getting a proper fan to blow air at my plants so their stems and branches grow strong

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

        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.

        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.

          I’ve seen a lot that are targeted to misbehaving devices, or proprietary charging standards.

          For example, you have a charger with Qualcomm’s old fast charge, and a phone with Samsung’s, so you use a trigger to negotiate the Qualcomm’s setting equivalent to Samsung’s and you get fastcharge.

          There’s also stuff like fnirsi’s usb tester, which can trigger fast charge for (you guessed it) testing.

            I have an obscure piece of hardware that refuses to negotiate the required power from a power bank I know can handle it. Can I fix it with a lil board like this?!

                I just didn’t know this is was a thing, the device is a Pine II controller from Black Forest Motion, which should take 10–24V DC via USBC. Power bank is capable of 12V but doesn’t seem to want to negotiate.

                  Maybe your controller supports only 10 or 24 and not 12 🤷. I’m not sure if that’s a thing.
