The website ChargerLAB has tested the standard iPhone 17 model'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 27W to 28W with these Apple chargers:
  • 29W USB-C Power Adapter
  • 30W USB-C Power Adapter
  • 35W Dual USB-C Port Power Adapter
  • 35W Dual USB-C Port Compact Power Adapter
  • 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 standard iPhone 16 can reach a peak charging speed of around 23W, according to ChargerLAB, so the iPhone 17 can charge a bit faster.


Even though the iPhone 17 Pro models can briefly reach a higher 36W peak USB-C charging speed, Apple says all of the iPhone 17 and iPhone 17 Pro models can be charged up to 50% in 20 minutes with a compatible charger, including its new 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.

As for wireless MagSafe charging, the standard iPhone 17 reached a peak charging speed of 29W with Apple's latest MagSafe Charger, according to ChargerLAB. For sustained MagSafe charging, Apple says the device can reach up to 25W speeds.

The regular iPhone 17 has proven popular so far.

I mean, that’s great for those who need it. Me, my 17PM right now is around 65% at the end of the day and it goes on the original MagSafe charger over night, to 100%. I’m not foreseeing that I’ll ever need to charge during the day. But as I said, for others this is great

The article says "charging speed", yet we are just told about how much power the iPhone will draw from the charger.

Where are the speeds? Does the new Apple charger charge to 50% in 20 minutes even though it pushes only 23W?

How long to charge to 50% with all these other chargers for comparison? For me, some wattage doesn't tell me how long it will take to charge.

I've never really understood the importance of charging speed beyond being "fast enough." My main charging happens overnight and I rarely have to top up during the day and I only have a 13 mini. I do plug in while driving in my car for CarPlay. Tried wireless charging/CarPlay and that just overheated my phone. I would love improvements to cooling (maybe the vapor chamber does this?) so wireless charging could work better on a phone that is also being used for GPS/CarPlay.

As nice as it is to have a universal connection with USB-C, the cable headache is very frustrating. Some cables can only charge while others are also capable of data transfer. Some cables can charge at fast speeds and others are only capable of slow speeds. And none of them except the authentic Apple cables advertise their capabilities well. What a mess.

40W Dynamic Power Adapter with 60W Max is just marketing fluff with the new iPhones!

Except those that believe the hype say "It'll charge your MacBook too!"...lets see, 40W charging on a MBP is not enjoyable and 60W is peak for a few seconds before the charger heats up. No point. You're right -- marketing fluff.

This is incorrect with respect to phone charging.

All USB-C cables support a minimum of 60W power delivery, which is more than enough to charge any iPhone at the maximum possible speed.

The cable can become a factor when charging laptops and other devices that can take power levels above 60W. In that case, a 100W or 240W rated cable can deliver faster charging speeds.

More than sufficient for a MacBook Air, however! The Airs ship with 30W chargers and even my 20W charger can do a semi-respectable job of charging it.

28w peak charging...welcome to 2015 Apple! :)

There's nothing wrong with 28w. Peak is a measure of nothing really, making this test pointless. Let's see total change time from 0% to 100%, 10% to 100%, 20% to 100% across various devices and chargers. If they were going to pick one test I'd choose 10% to 100%. I virtually never go past 10% to plug in.

I charge my M4 MBP with a 30w Anker GAN charger, mostly because it's small...not much bigger than the original 5w cube. It's not fast, but does fine.

It would do "fine" as long as your usage does not exceed 30W discharge, then your tiny Anker will not keep up--battery will discharge as input is less than output.

You didn't say which MBP you have (M4 or M4 Pro, 14" or 16").

And there are plenty of chargers for your Air already, right? What would the 40W/60W give you that you don't already have?
