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?

Intended purpose? Probably to be sold to people who don’t know about modern USB specs.
Actual use case? Monopole antenna?
It means it does 10 Ampère charging. It’s part of the USB 3.2 spec.
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
Where? I can’t find any reference to any device being allowed to draw 10A: https://en.wikipedia.org/wiki/USB_hardware#Allowable_current_draw
