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 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)

[–] tobogganablaze@lemmus.org 35 points 2 months ago (1 children)

The highest USB power delivery standard currently uses 5A at 48V for 240W.

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

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?

[–] DomeGuy@lemmy.world 5 points 2 months ago

The elecrelically semi-literate side, obviously.
