It also doesn't actually matter at all. You just plug it in and it works. How well it works really doesn't matter in 99% of cases.

And as time goes on the absolute minimum you will come across only goes up and never doesn't work.

So unless your casing the absolute newest feature set where you absolute need say thunderbolt 4 not 3 or 2. Then it doesn't matter.

For wattage you can just read the brick. Its required by law to have that information right on it. For the cable if it doesn't work go but a new cable and retire your old one. Iv had two replace my main USB c to c cable once ever because it wouldn't handle the wattage i needed it to.

Its just a seriously non fucking problem for 99.99% of people.

The minimum feature and watt spec of every cheap piece of shit is well past the point normal people care.
