With the 25W MagSafe from Apple, it's required to be paired with at least a 30W adapter to be able to output 25W to
your phone.

I haven't found an aftermarket 25W one yet.

Me Either! If I find something I'll post it here.
 
the pucks look the same size as the old ones, There are several stand options that have a cutout that the MagSafe puck will fit into.

I searched google for "empty MagSafe charging stand" and several came up

That's true they are similar in shape but they are not exactly the same size. The new one is 0.4mm narrower and 1.0mm thinner.
So presume I could use my MBA M1 adapter then.
As long as it's 30W it will charge the 16 Pro/Max at the advertised 25W.

It will only charge at 25W if your phone’s battery is very low like <20%.
 
The source is me - measuring with iPhone 16 Pro, USB-C meter, and the new iPhone 25w MagSafe charger.

But if you'd prefer a YouTuber:


Nicely done and thorough test. I don't see where you tested it out at let's say 40% to see the charging rate from there.

Sorry I didn’t mean to take credit for the video, rather I did my own testing.

You can see the approximate charging rate at 40% by looking at the graph in the timestamp I linked. It’s about 10w.

I wonder if it has anything to do with the heat being produced and it's Apple's way of prolonging the longevity of the battery capacity.

Of course. It’s the same with wired charging. They all slow way down as the battery gets more full.
