Apple's widely rumored trio of new iPhone models expected to be announced in September will feature 18-watt USB-C power adapters in the box for much faster wired charging, according to ChargerLab.

The new, rounder-shaped power adapter would connect to an iPhone with a Lightning to USB-C cable, also expected to be included in the box, enabling much faster charging speeds than the tiny square-shaped 5W power adapter included with current iPhones. A render of the European version is shown above.

MacRumors tested the iPhone X with various third-party 18W wired chargers last year, for example, and found that the device reached a 79 percent charge after one hour. With a 5W charger, the iPhone X only reached a 39 percent charge in that time. We explained our methodology in detail in that article.

Today's report, based on information from "inside the production line," corroborates a post on Chinese social network Weibo that also claimed 2018 iPhones will come with an 18W USB-C charger and a Lightning to USB-C cable in the box. That report included drawings of what the North American charger may look like.

All in all, the new 18W power adapter would generally charge an iPhone at least twice as fast as the current 5W charger. Fast charging is supported by the iPhone 8, iPhone 8 Plus, iPhone X, and presumably future models, rumored to include a new iPhone X, a larger iPhone X Plus, and a lower-priced 6.1-inch iPhone.

I'll bet that from a materials cost (BOM) and manufacturing perspective, manufacturing a higher output charger doesn't cost much more money if any than the little 5W charger. The artificial elevated prices of these higher powered chargers only exists because Apple enjoys jacking up the price.
 
Does this mean the models mentioned (iPhone 8 and so on) could be charged by (for instance) a MacBook Pro USB-C charger with a USB-C to Lightning cable, drawing enough juice for its need? Or could the 65W rating of the power supply damage it?
 
what the hell even is that “render” of the european version it looks like a **** blender beginner’s render and what exactly even about their design differentiates it from the standard non-usb c wall wart
 
Fast-charging for iPad typically has meant 2.1A@5VDC, or 10.5W chargers. Traditionally Apple-included iPhone chargers are 1A@5VDC, or 5W.

With 1these 8W chargers, then the amperage is scaled-up to 3.6A@5VDC. Or a whopping 360%.

I assume that the charged device controls the amperage supplied by the charger, via current limiting. Or, otherwise, bad things will happen.
 
I hope it's not damaging. I use my macbook pro USB-C charger for my phone all the time.

Does it reduce battery life if you always charge using fast charging ?
That's a very good question and a very common one. It does not affect battery life but it generates more heat than slow charging. Now, heat does impact battery lifespan and it damages your battery quick.

Yes, the iPhone regulates the current it is receiving. It doesn't matter if you charge it with a 29W or 87W USB-C charger.

Apple's philosophy is to price products based on their own idea of how insanely great magical they are to us, the fortunate customer. At a bare minimum, they get their 50% gross margin; be it laptop, cable or dongle.
 
Don't forget they are also supposedly removing the lightning to 3.5 audio jack dongle from the box.
I thought they would remove it with the 2017 iPhone lineup. I assume they would remove the adapter this year as people are buying bluetooth headphones and Airpods...
