I just went to charge my kitchen scale and it wouldn’t work until I dug out a USB-A -> C cable and plugged it into my desktop…

It just reminded me of how many devices like that I have. This scale, my wife’s sound torc, some car jumperstarters, and I think a one or two more…

I assume it’s because they just slap a usbc port on a dumb 5v circuit that doesn’t have a power negotiation controller. So the cable and the charger cant figure out the power needs of the device are and just never send any.

    Way to complex and expensive. This just needs 2x 5.1 kOhm resistors between the CC pins and GND.

      Yeah, the cheap cables they provide are often only vcc and gnd with the data pair shorted in the plug.

      Trying to use a normal plug confuses the controller.
