Interesting approach, never thought about using the cable for something completely unrelated.

Thanks, that's pretty much exactly what I found: https://en.wikipedia.org/wiki/USB_hardware#Allowable_current_draw

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?

The USB-C standard and particularly the USB PD (power delivery) is so complex it almost feels comical.

The PD standard document (freely available on usb.org) is over 800 pages long and features a lengthy part about the role of the cable alone which is mostly hidden from the user. Here's a short video about this issue: https://www.youtube.com/watch?v=6bZ0y9G-4Pc

There is a lot of variance in regular USB-C cables in c/technology@lemmy.world

That's true, they explain this in a different video: https://www.youtube.com/watch?v=y9vXDy_zt4I

I learn more about cables in this channel every week. Just wanted to share

USB-C cables can talk in c/technology@lemmy.world

It indeed is, but there seem to be no testers available for resistance measurements.

The USB-C cable tester in this video looks really good, but it seems to be unavailable for now: https://ble.caberqu.com

Are there any alternatives I can buy right now?
