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?

48V, 10A at 6 feet or less length requires 16awg wire for <=3% loss (which is the critical appliance standard rather than the more lax >= 10% used for most DC circuits). That's a wire with a conductor diameter of 1.3mm ~= 0.05in.

The cable probably isn't 10A rated. But, it's not an overly thick wire to get it done. Most of the girth is insulation and shielding.

This is overly simplified. And, I didn't care to watch the video.
