I learn more about cables in this channel every week. Just wanted to share
The video is in English and it’s about how some cables support USB PD power negotiation better than others, it seems. I only watched a few moments.
I ended up just buying a tester
This is the one I bought
Treedix USB Cable Data Line Test Board https://a.co/d/15h4lEh
It’s a bit of a pain to learn what means what, but once you read up on it, it’s pretty straightforward.
Same. Mine is made by Treedix.
$17 on Amazon.
It is great at determining the technical limits of a cable. To read the test you have to practice a lot or reference a chart that was confusing to me.
It does not tell you whether the cable functions, only what its technical capabilities could be if it was working as intended. In other words, as I understand, it checks what pins are there on each side of the cable, not whether they are connected anywhere in the middle.
It’s good for sorting through all the crap cables that accumulate and figuring out which ones can’t do shit and which ones can stream high def video and power a small computer.
Some basic cables only have power, no data at all.
That’s what’s universal about USB, the ports and connectors, not the cables.
It gets worse, not all usbc ports are fully featured either.
That’s true, they explain this in a different video: https://www.youtube.com/watch?v=y9vXDy_zt4I
Yall just ruining the U in USB.
