>No need to overthink it. USB cables should just label themselves with their bandwidth - it's not rocket science.
And yet, this requirement already misses the other thing it should state: it's power rating. Because even two cables with the same bandwidth can have widely different power rating, and thus powering capacity or charging speed for different devices.
I have no respect for a man who can't label a cable with more than one figure.
Don't take this comment too seriously, just a curiosity.
Powering capacity sometimes matters, but are there any devices out there where the charging speed would be meaningfully different? As in, they use significantly more than 60 watts to charge? (I looked up some of those super fast charging phones and they don't seem to be following the USB standards in the first place.)

Any device which can charge at 100W or more? Like lots of laptops, as well as my ebile batteries?

Soldering irons can benefit from being able to peak above 60W when heating.

"Lots of" laptops? Upon searching a bit harder I think the 16 inch macbook pro can probably do it. Most laptops that can hit 50% in half an hour don't have a big enough battery to charge at much over 60 watts.
Ebike is interesting.
