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.…

    From listening to a 1hr presentation by a furry in VR chat. Its likely because USB C is bloated. Its to complicated if all you need is power delivery in a small form factor.

    You could use a usb c connector and not comply with the rest of the spec maybe idk shit about electronics.

      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.

          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 + & -

          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

          You don’t need to follow the entire spec for a usb c. Usb c has a display port mode, but most laptops that have this won’t have it on every port. Most usb c cables also don’t support display port mode, which is annoying because they usually won’t say if it supports it.

          Usb c extension cords are not allowed and yet they exist

        Unfortunately it’s a bit of a misinterpretation. Yes the overall USB C spec is complicated, and cables can support different things without being labelled clearly, but you can use it just to deliver power much more simply.
