As I understand it you can do USB-C at a basic 5V level with 2 resistors, and for a watch that would be plenty of power.
yeah but that wouldnt be USB C because usb C is a standard that requires a ton of different things like double way data and power rails and handle 60watts etc. If you just need 5v then you can do it in a much smaller way via another connector or even wirelessly.
I'm gonna assume you know more about this and I do because i cant even light up an LED in a circuit.
USB C does not require all applications use all aspects available in the current spec (USB 3), that’s just silly. Take the latest iPhone for example (not the pro series,) they are all essentially running USB 2 through a USB C cable. And that’s perfectly fine.
The real problem is when a company uses USB C but follows none of the wiring or standards requirements for any standard. Such as running power over data pins making the charger some proprietary Frankenstein of bullshit.
cough cough ~~Nintendo~~ cough cough
USB C is only the plug… USB 3.2 is the specification
USB power delivery is part of the specification that you can support without support for the other parts and is incredibly simple to implement by itself
It doesn't need all that. All the complexity is because of stuff that's been added to the spec. 500ma@5v will just work if all you only connect is + & -
