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’ll save you guys from watching. It was just a bog standard crappy USB C cable. This video reeks of advertising to me. The tool which was used to identify the cable (which tbh I thought was pretty cool, so I searched it using the obvious hints in the video) is a kickstarter which is starting sometime today. Awfully sus!
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.
Haha pretty much
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…
I mean, isn’t it a usb_c cable that the manufavtuer claims can handle 10 amps of current at once? (which i think may be on the low side)
5A is the max rating for USB-C. What you’re looking at is probably a 5A cable with a “10A” molded into the connector in true sketchy knockoff fashion.
To answer OP, USB-C connectors are often used outside of phones/tablets like with hobby electronics like boards to control LED strips that could benefit from more current. Unless this cable is super thick, there’s little chance it can actually handle 10A and even if it can, the connectors aren’t rated for that much current.
Interesting approach, never thought about using the cable for something completely unrelated.
If that’s the case, it’s probably not even a 5A cable. It will be the cheapest cable China can produce.
Yeah damn those sneaky Chinese, forcing Western capitalists at gunpoint to buy their fraudulent goods en masse for markup and resale to Western markets. If I wanted shitty manufacturing, I would have bought American and saved us all some carbon!
In what world are you living where 10 A is on the low side for general-purpose electronics?
The elecrelically semi-literate side, obviously.
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.
