The reign of the Lightning cable is over, and the USB-C era has begun — leaving us wondering what sets one charger apart from another. We do a teardown of Apple's Thunderbolt 4 and its competitors.
Same feeling honestly but don’t forget that it still would take research to buy the right one. Think about SD cards and their various speeds. You still need a chart to make an informed purchase.
They do have standard icons for them, but it’s not required to use them. Companies like Apple are a problem case there since they value a clean look over information, random Chinese brands sometimes use them.
As of USB-PD 3.1 there are now nine fixed voltages - 5, 9, 12, 15, 20, 28, 36, and 48V - and two variable-voltage modes; PPS with 3.3 - 21V in 0.02V increments, and AVS with 15 - 48V in 0.1V increments.
Combined with a few different current limits, some of these features being optional, and then doubling down with what your cable does or doesn’t support, amazing anything gets charged at all.
It’s also easy to forget that degradation on the highest spec cables is pretty severe. A 1m full spec thunderbolt 4 cable can be made dirt cheap but there extremely limited 3m cables to the point that $160 is reasonable despite it sounding silly
So I’m ignorant here, but what is the spec difference between the supplied iPhone USB-C cable and the one that comes with the newer MacBooks? I never bothered to look, but I did mark the one that came with my MacBook as I assumed it was higher rated than some other cable (although I still just charge with the MagSafe adapter anyway).
Interesting find that the cheapest cable is actually not the worst. Too bad the USB-C spec allows such a mess of speeds and charging standards.
I wouldn’t mind the various levels of there were a simple, consistent marking standard for speed and power rating.

That is part of it, but I kind of feel like PCs and phones need better reporting to the user, if adequate data is accessible to the host.
If I’m being bottlenecked in thoughput by speed or in power by the PD capabilities of a cable, I’d like the host to tell me if it can figure that out.
There are like 5 speed and 5 power levels. The only alternative is all cables are stupidly short and expensive.

Not to mention unhelpful names like “full speed”, “hi-speed”, and “super speed”.
