The website ChargerLAB has tested the iPhone 17 Pro Max's USB-C charging speeds with a variety of Apple's chargers, from 18W to 140W.

The device reached a peak charging speed of around 36W with the following Apple chargers:
  • 40W Dynamic Power Adapter with 60W Max
  • 61W USB-C Power Adapter
  • 67W USB-C Power Adapter
  • 70W USB-C Power Adapter
  • 96W USB-C Power Adapter
  • 140W USB-C Power Adapter
For comparison, the iPhone 16 Pro Max can reach a peak charging speed of around 30W, so the iPhone 17 Pro Max can charge a bit faster.

The smaller iPhone 17 Pro can likely reach the same 36W peak.


Apple says the iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max can be charged up to 50% in 20 minutes with a compatible charger, including the 40W Dynamic Power Adapter with 60W Max. For comparison, the iPhone 16, iPhone 16 Pro, and iPhone 16 Pro Max can be charged up to 50% in 30 minutes with a compatible charger.

Apple's 40W Dynamic Power Adapter with 60W Max is available to order in the U.S., Canada, China, Japan, Mexico, Taiwan, and the Philippines.

Keep in mind you also need an appropriate USB-C cable for fast-charging capabilities, with the most basic or cheap options sometimes not supporting enough power delivery. If you are unsure, the USB-C cable included in the box with iPhones does the trick.

For anyone interested (particularly those that live in markets where Apples dynamic charger isn’t available) I bought and tested the Pixel Flex 67W PD3.2 charger:
As we don’t have Apple’s Dynamic charger available in the UK, I bought the Pixel Flex 67W which also supports AVS and PD 3.2

I saw a peak charging output of 37W at 10% SoC, dropping to 24W at 40%. This is a 27% increase on the 16 Pro Max

If anyone’s interested, when the peak charging rate was achieved, I saw 46m to 80%

Note: the peak wattage I received on my 16 Pro Max previously was 29W.

I’ll be comparing this with a ‘regular’ 96W Apple charger over the weekend…

Are you able to test Apples Dynamic charger? I’d love to see the results!
 
So when they say max is 36 watts... shocker it doesn't charge faster with a higher wattage charger....

That is not how PD works. The device being charged tells the charger what it wants, and the charger then looks at what it can supply and what cable is being used. Then it supplies the power that is compatible with the least powerful of the three.

The iPhone will never ask for more than 36W, no matter which charger you use.
 
While you’re at it check the data transfer speeds from the USB port, not just the specifications but actual real-time data. :rolleyes:

I think Apple specified that it supports USB 3.2 2X2 10 GB speeds but which Apple computer supports USB-C 3.2 2×2? My M2 studio max does not support that speed.
 
Apple dynamic power adapter is a joke!
Would not call it a joke. Maybe overpriced. The marketing is also a bit deceptive. Most users would probably be better off buying a slightly larger charger that can sustain 60 W for longer periods of time.
 
"40W Dynamic Power Adapter with 60W Max"

I'm confused; is Apple trying to do their own thing again rather than follow the USB-C PD specifications?

Dynamic charging sounds mysterious. Chargers from other brands will do the same thing (throttling) though. For some reason Apple's marketing department decided to make it a feature, as if it was something special.
