iPhone 11 Pro What is the maximum wattage charger iPhone 11 pro will work?

In practical terms you're going to max out at about 30W, but make sure you're using a charger that follows the PD spec. Not all do. You can use a larger charger, but the 11 Pro will only draw about 22-23W.
thanks! I have a 2017 MacBook 12”which is using 30 W charger.
Can I use same charger for iPhone 11 Pro to get 22-23W charge?
right I mean I was just wondering if it’ll be faster than 18 W and what is the maximum charging W
Yes, that's excellent - but the earlier 29W charger that used to ship with the 12" MB does not fully support PD charging and is not a good choice.

It will be maybe 30%-ish (big emphasis on 'ish') faster than the 18W. You can use whatever you want - the 81W MacBook Pro charger, for example. But it won't charge any faster than a 30W PD-compliant charger. The phone manages the wattage it draws to charge the battery.
Ok great so my 30W charger which came from 2017 MacBook 12” is PD? So I’m getting 30ish?
One way to find out is to drain your iPhone down to 60% (because it slows down += 80%) and plug it into this: https://www.amazon.com/P3-P4400-Ele...ywords=kill-a-watt&qid=1572216113&sr=8-5&th=1 via the desired charger. That will tell you how much power is going to the phone.

Some quick internet searching:
iPhone 11 Pro Max can charge at up to 20.7 Watts
Just as a FYI, If you use a USB-C PD charger capable of it, The iPhone 11 Pro Max can charge at up to 2.3 Amps @ 9 Volts = 20.7 Watts. I personally carry a Macbook 30 Watt charger around with me, so it's a nice surprise for extra fast charging :)

No, the phone is not going to draw more than 22-23W, like I said earlier. That's why an 81W adapter isn't going to charge it any faster than a good 30W adapter.
^ had it right. And again right in post #9 - you could plug your phone into a 10,000 watt charger and it would only draw 20-23w. The charger is actually in the phone, the power brick is just supplying power to the device.

It's a small thing (well, about 10%?), but I think Chargerlabs found that the 11 Pro Max would draw about 22-23W.

10kW charger? - haha, you can get those, yes. They come with wheels and run on gas or propane.
And for sure, as you say, it ain't gonna charge faster!10kW charger? - haha, you can get those, yes. They come with wheels and run on gas or propane.
I drool every time I walk by one (and then take a picture). People do think I have a problem... but I don't. Seriously, I don't. The big cat diesel ones ... yeah don't get me started.
You will not experience any significant difference between a 30 watt (or larger) PD charger and the 18 watt charger in the box.
The ~22W max of the 30W, and the 18W of the charger in box is delivered for a short time at beginning of charge cycle on a discharged or nearly discharged iPhone. The wattage is stepped down from there. The majority of the total charge time to a full charge is done at less than 5w using either of these chargers.

Not all that short a time. The 22-23 watt Maximum is permitted by the phone’s charging circuit from 0% to mid 70%. After that particularly above 80% the wattage is reduced until you have an intermittent trickle charge at 100%.
I have used the 30 watt charger for years and have found below about 75% I see about a 1.3% increase per minute. This means that if I plug in at 40% I reach close to 80% in half an hour.
18 watts is not much less than 22 watts so results are only marginally better than using 30 watt charger.
I think you're right. The quickest relevant comparison that came up with Google is from a test done by MR. Here's the relevant graphic, which shows that using a PD charger above 18W charges has essentially no impact. I was a little surprised. That was with an iPhone X, not an XS or an 11 Pro. I sort of doubt that Apple has changed the charge controllers in the newer phones, since the biggest constraint is probably battery chemistry, and that hasn't changed. What surprised me a little more was that the old 12W iPad charger does almost as well as the more sophisticated USB-C/PD chargers (second graphic below).
Test mentioned in my post above was from Inviolabs, because it measured watts real time (as well as charge time vs. %). It was on an iPhone 11. There are other tests like what you found, including tests on earlier fast charge capable iPhones....all show essentially the same result as the data you posted re. 18W vs. 30w+.
The Inviolabs (iPhone 11) test resulted in (30W/18W PD)...30 min. 55%/53%, 1 hr. 84%/80%, and both reaching 100% within a minute of each other. Insignificant difference, certainly would not justify carrying bigger heavier charger just for the phone, or worse yet buying one.
And, yes, the good old low tech. relatively small and light 12W iPad charger is a gigantic improvement over the 5W. And does nearly as well as 18w/30w PD chargers. I‘ve been using on iPhone for years, when I needed a fast charge.
I’m not expert on Mac chargers, so don’t know. But it doesn’t matter. Plug it into your iPhone if you want to. The phone will limit the charge watts as necessary to protect the phone in either case.
If it is, it isn't shown on the Apple webpage. https://www.apple.com/shop/reviews/MR2A2LL/A/30w-usb-c-power-adapter
However, comments say there was a previous 29w adapter that wasn't PD and this one replaces it.
Seems to support that it is indeed a PD supporting charger.
I believe it does support PD.
Edit:
Oh check out the small image of the adapter. Looks like it has PD next to USB C. Check your adapter.

Just checked my 87W MBP charger (USB C) and it says PD on it - tiny tiny writing. I'd venture to guess the others do too.

Dude, hate to break it to you but if it went from 28% to 44% in 6 mins, there is something wrong with your iPhone. Only happens with defective batteries.
