USB-C is simply the connector format -- which can then be used as either USB 4 or Thunderbolt 3. The highest speed USB 4 devices are effectively the same as Thunderbolt 3 from what I understand.

I really do sympathize with any consumer who has to try to make sense of what a given port is actually capable of these days.

The Chuwi Hi10x is a nice enough Windows tablet - sort of a cheap and cheerful Surface, but really a grandkid of the Asus T100.

It is powered with a 12V, 2A charger via one USB C port (and just one of the existing two). But try to use a standard USB-C PD charger, and nothing happens. However it does charge with a plain 12V charger, sporting a USB C jack, that does not require PD negotiation ...

I'm coming to think that having one connector for everything may not be easy ...
