Has anyone ever seen a "10A" USB-C cable and can tell what their purpose is? (www.youtube.com)

The video dissects a USB-C cable marked with a 10A rating even though there is no such rating in the standard.

It would be interesting what this is meant for, as I've never seen a device with such a rating?

Sometimes you can find spec-bending similar-but-different tech implementations within closed device ecosystems that aren't meant to interface with third party equipment. With that said I doubt this cable is an example of that.

    The spec is too use 4 of 24 pins each for power and another 4 for ground. What if you used 16 pins for power? One could even be reckless enough to use 22 pins for power If the ground isn't tied together, but that means you have to take a moment to sense ground.

    Maybe you will see 8.5a at the device, but 10a at the source with the cable heating up..
