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?

Is this about emarkers? It's just advertising cable speeds and power capacities for charging.

[–] lemann@lemmy.dbzer0.com 4 points 4 months ago

I believe cable length is included in the emarker data too, probably useful in conjunction with PD PPS to identify whether the cable is damaged based on the resistance/voltage drop

[–] tia@lemmy.world 3 points 4 months ago

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

Would be nice if there was something that could read the outputs/inputs on proprietary USBc implementations. Like my Asus tablet that only charges at the full 100w with the OEM charger.
