They name by committee. So every corporation that is in the USB standards group will argue for whatever benefits them, with no consideration for consumers.
I fucking hate it. Buy a USB C cable and it’s a crapshoot whether it’s USB 2 with no power delivery, or poor quality with power delivery. Just trying to find a good quality USB 3 cable is difficult, with 3.1 or 3.2, x2 or not, shitty control chips, etc etc.
It is absolutely infuriating. It blows my mind that you can have a USB 3.2 Gen2 cable that does everything you need it to, except for the fact that it doesn’t support Power Delivery and a lot of the time you won’t even know, so if you’re sending high wattage through it there’s a real possibility you’re gonna burn some to kind up.
In theory, compliant devices can detect the voltage drop over shitty cables and request a lower charging rate.
Anything over 3A or 60W requires the cable to have an e-marker. A little chip inside one of the connectors that indicates what the cable is capable of. No USB certified device should try to pull 60W or more through a cable without e-marker or anything above what the cable can handle if it does have a marker.
