iPhone 17 Pro Max's USB-C Charging Speeds Tested With Apple Chargers

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.

iPhone 17 Pro USB C Port
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.

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.

TL;DW:



had no idea "good" MagSafe was that competitive with a plug, but I'm still annoyed that there's no good USB-C docks on the market anymore.

You would be slow charging a MacBook at that speed. iPad Pro charges at 20 watts max.
That is incorrect. My iPad Pro M1 charges at 37.5 W. Your figures are completely underrated.

so why buy the new dynamic 60W charger if the phone can only do 36W peak? More Apple (mis)marketing?
Why 60W? Maybe you want to charge a MacBook. Or maybe an iPad Pro.
