Has anyone ever seen such a "10A" 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?

Is it? I think USB 3.2 only goes up to 20V 5A for 100 watts of power. I don't think 10A is in the spec.

This cable also turns into a heater at 10A, so I don't think it can do it for long. You need a pretty thick cable for 10A, 3 times as big as you need for 5A. So cheap Chinese cables won't do 10A even if they use copper instead of CCA.

Pretty much what I expected, but I don't think they care to much about that
