Its so classically Apple that just when most brands are starting to standardize on PPS (Programmable Power Supply) to allow any voltage to be used, they come with an alternate standard AVS (Adjustable Voltage Supply) just to force people to buy their certified chargers.

The sole benefit of AVS over PPS is that AVS goes beyond 100W. But these chargers only do 60W. And it would have cost Apple almost nothing to also add PPS to their phones and chargers.

Edit: hello fanboys :)

AVS was created by the USB PD specification team (the USB Promoter Group/USB-IF), not Apple. AVS was introduced as part of PD 3.1 in 2021, albeit for >100W only. I believe Google was technically first out of the gate with a charger that supports the PDS 3.2 flavor of AVS.

You're completely ignoring that Apple is purposely choosing not to also add support PPS and instead use AVS so they can push people from generic Anker / Belkin / Baseus PPS chargers to their own Apple chargers. For a while anyway.

It would make more sense if they used it for their MacBook chargers, but AFAIK the sole charger they having going beyond 100W is the 16" Pro charger at 140W. Every other Macbook charger is between 45W-96W.

This is coming across as more than a bit delusional. Adding a new standard to a charger is not “forcing” anyone to avoid other chargers in any sense. AVS adds functionality to this charger, it doesn’t take it away from other ones.

If AVS is only part of the USB-C PD spec over 100W then yes Apple is doing something non-standard and not "adding a new standard." They're going to make 3rd party charger providers add some Apple-specific logic that isn't in the PD spec and isn't used by any other devices if this is true.

If this is true, then if you own a 3rd party charger that is up-to-date with the very latest USB PD specs, your charger is going to charge an iPhone 17/Air/17 Pro more slowly than buying Apple's new charger.

(I don't claim to know the technical details of whether AVS is part of the spec below 100W or not, I am just going by the comments in this thread and speaking of the hypothetical)

		Since I wrote my comment I found out that yes this is a standard, the 3.2 version of USB-PD. https://youtu.be/TYEqCgMnA8U
