It looks like the new Google's Pixel 4 watch comes with yet another incompatible change in charging technology. This is a ridiculous situation. The original Pixel Watch used one type of wireless charging. Then the Pixel Watch 2 & 3 removed wireless charging and swapped to a different charging mechanism. And now the 4 has changed again. So three different charging cables in under three years.…
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
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.
