Anyone can use any of the USB connector tips or casings and not adhere to any of the standards. Buy a knock off or something custom and you can fry hardware easily.

16-Inch M3 MacBook Pro Can Fast Charge Over USB-C With 240W Cable

That's why USB-IF certified cables are recommended.
The old 16-inch MBP was launched after the USB PD 3.1 spec was announced but before chips were available on the market.
It really kills me that it’s limited to USB 2.0 speeds though 🤣. I guess that’s why it’s so cheap (for Apple).
sometimes I just feel safer buying from certain suppliers, like direct from Apple, Microsoft... or trusted department stores etc I have bought from, know and trust . I feel enforcement of standards indicated on products can be a Wild West in some parts of the world.
how is it fast change but also slow speed I would think fast change cable would be able to be fast data as well
The specs on apple.com say it has two Thunderbolt 3 ports with speeds up to 40 GigaBytes per Second.
So you can’t fast charge it with every usb c port how do we know what ones are faster
Both ports offer the same data speed, and both ports offer the same charging speeds.
Where did you read that one port offers faster charging?
Sorry don't know why I thought we were talking about the M3 base. Yeah, all three USB-C ports are fast TB4 and offer the same fast charging.
The USB-PD(power delivery) spec only recently added support for up to 240 watts, that’s why.
My question is, what power level does the MagSafe 3 cable it ships with support?
USB-IF compliance program now only allows a cable to be spec'ed for 60W or 240W, nothing in between.
Curious about the habits of MBP users, do you keep your mbp’s plugged in constantly if you’re at home at your desk, or do you unplug it let the battery drain? With the ability to rapid charge, wouldn’t that alter the behaviour of users, causing more battery cycles, less battery life with that and also the heat I imagine is generated from that type of charging.
To everyone saying USB-C is a tripping hazard:
If someone is using a TB4 dock then that USB-C connection is made anyway. Using one cable instead of two is convenient. Currently only the Dell Ultrasharp 6K (U3224KB) has 140W power output to the host. TB5 hosts will be required to charge at least at 140W.
I agree that MagSafe 3 is great for mobile use but having the option of using USB-C at full power is good too.
I don't buy that Apple cannot enable 140W charging on 2021 and 2022 models with a firmware upgrade. The circuits to handle 28V/5A are already there. This is likely Apple trying to differentiate their newer models with artificial limitations.

Port isn’t the same. Uses a new generation of components not available when the first M1 MacBook generation was being designed.
To support 140 watts over USB-C it needs the connector itself to be USB-C 2.1 compliant, and it needs a new controller. And it needs PD 3.1. Such things weren’t on the market yet in the M1 and M2 generations.
