ive noticed my max charges faster if i plug it into my iMac to charge vs plugging it into the wall.. my phone wa son like 40% and i plugged it into my iMac and i got to 100% in less than 20 minutes
My XS Max does not double chime either but is fast charging. In fact at double the rate of my X. Getting one percent gain every 20 seconds with XS Max. Where best X did was one percent every 40 seconds. These rates confirmed at about 50% battery charge level.
Hey - Are you thinking something like this? https://www.amazon.com/Anker-PowerPort-Certified-Foldable-Delivery/dp/B0721DV7YX
iPhone / iPad into top port (USB-C), Apple Watch in bottom port (USB-A).
When you say "USB-A", what do you mean? Just a standard USB rectangle connector? From my understanding, you need USB-C w/PD for fast charging. I don't think it's possible to "fast charge" the watch, only the iPhone / iPad.
FWIW, I did a comparison on 2x iPhone XS.
Variable 1: Anker 40W w/ USB-A to Lightning (OEM Apple Cable)
Variable 2: Apple 30W w/ USB-C to Lightning (OEM Apple Cable)
In 1 Hour, I got to the following charge levels:
Variable 1: 62%
Variable 2: 76%
Something with USB-C / PD is happening, but I couldn't tell you all of the details. I would love for Apple to publish a more comprehensive article vs. what they have right now (https://support.apple.com/en-us/HT208137)
The removal of Double Ding on iOS 12 also complicates things, to me it would almost be a marketing play to have a prompt where the iPhone / iPad detect USB-C PD and the incoming charging Voltage*Amps (= Watts) and have a prompt to say "Fast Charging Enabled".
Hope that helps...

Yes thanks so much for this! The only reason I was wanted the standard USB port to also be able to support fast charge would be for if I was for example to be charging my Switch via USB C PD and then my phone on the standard USB port just to get as efficient of a charge as possible. I will definitely look into the power adapter you linked!

my xs max detects charger at start with 15W but after a few second it shows 21W (coconut) , x would detect the same charger with 17W , but charging with the same 12W.
To add more data, I submit the following from using Amperes-bat App.
iPhone X
Apple 29w USB-C adapter & Apple 2 meter USB-C to lightening cord.
17% to18%, 40 seconds for one percent battery level rise, showing 2,443 mA.
IPhone XS Max
Apple 29w USB-C adapter & Apple 2 meter USB-C to lightening cord.
48% to 49%, 24 seconds for one percent battery level rise, showing 4,321 mA.
Apple 5w Adapter & Apple 2 meter lightening cord.
36% to 37%, 119 seconds for one percent battery level rise, showing 900 mA.
As you may note, the XS Max using the same 29w adapter charges almost twice as fast as the X.

Simple, because the USB-A to lightning cable is the bottleneck, the cable maxes out (the chip in the cable) at a certain power level. Forcing more power through the cable from the brick won't increase USB-A to lightning charge times. USB-A can only handle 5volts/2amps (10 watts).
The USB-C to lightning cable can handle more power through it. USB-C can handle 20volts/5amps (100 watts).
MR already did a test last year and buying the USB-C brick and cable really wasn't the best value. Using a 12W or above brick for maybe $10 on Amazon and your in box lightning cable was the best bang for the buck.
If that extra 8-10% charge over 30 to 60 min is worth $40-70ish then go for it; I would say it's not over spending $10 on a 12w brick.

I wonder when I do get my 2018 MBP-TB if I can use that charger to charge my XS Max for fast charging. I read somewhere, but not sure, the chargers are compatible.

Same here. I got my Xs a few days ago and when I plugged my 30W usb c charger in, it dinged twice. Not anymore though. Then I updated to 12.1 and still no double ding. It charges fast still though. 12% in less than 10 minutes.

The benefit of the 29w isn’t in the race from 0-100% it’s in the earlier percentages. After a certain percentage the phone will stop accepting all that power and switch to a much slower charging to deter cell degradation.
The third-party USB-C chargers are worth it if you are in a hurry and want a quick boost. If you charge over night then no difference between 12 W ipad charger vs USB-C. I do agree that the earlier charging rates are only 10% different. So it's splitting hairs.
At the moment i'm using a ipad 10w charger, it's quite impressive and not far behind a S9+/Note 9 when charging.
Actually no benefit in going over 18w. The pixel 3 fast charger(18w) is a hell of a lot cheaper than the Apple 30w charger and works great. You need to buy the usb-c to lightning cable no matter which charger you choose so there are choices besides Apple out there..
This. Even using an Anker 2.4a charger will be almost as fast as fast charging. I have a MBP 2017 13' and got the USB C to Lightning cable but I prefer to use Anker's 2.4a charger.
Fast charging is fine the way it is being done today. In the early days of rapid charging phones got burning hot and continued to rapid charge. Now days, as some noticed in this thread, fast charging doesn't heat up the phone that bad, but if it does, Apple will decrease charging speed. Also, past 80% rapid charging changes to normal charging to eventual trickle charging past 90% to help the battery keep its health.
The included 5w brick that comes with iPhones is pitiful and really slow. Get an iPad charger or a 2+ amp (Anker) charger and you'll get near the effects of rapid charging. I've been doing this to my iPhones since the 6+ and there is no effect on health.
What will change battery health is draining your battery below 20% regularly, using it in the hot sun or leaving it in the sun in your car (heat), or doing heavy battery draining activities all the time like watching 1080p video or playing CPU intensive games. This has more of a detrimental effect on the battery's health or capacity from design capacity.

Oh great I missed this when reading on my phone earlier. Yep. Get a 2.4a 12w anker brick for much less than the USB C options and it's almost no different. $10.99 - https://www.amazon.com/Anker-Charge...&qid=1542467517&sr=8-1&keywords=anker+charger
