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?

I'm willing to bet that this is one of those sketchy knockoff cables. The usb-c standard, called USB power delivery doesn't support 10 amps. Likely it never could because it would require thicker cables and more heavy duty connectors than what USBC actually has. Anyone who knows anything about basic electronics already knows this, more specifically what happens when you put too much current through a cable that's not rated for it.

All I can say is that I hope there aren't devices that try and actually pull 10 amps through a cable like this, it would probably not end well.
