There is a special place in hell for modern manufacturers of devices that have a USB-C port, but won’t charge from a modern USB-C charger. (fedia.io)

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.

USB c has active negotiation for power and communication via a cc pin

The usb a to c cable has a pull up resistor that mimics this and says “give 5v”

Some usb c chargers have a fallback 5v mode for this scenario but not all do
