While Apple finally added wireless charging to iPhone X and 8, there was no reference to fast charging during presentationof the company. As it turns out, Apple decided not to mention it in the presentation for a simple reason: 
New iPhone supports fast charging, but you need to buy a special adapter to use it.
9to5Mac noticed first feature on Apple's official spec pages. The company reports that all of its new phones are capable of charging at 50 percent from zero to 30 minutes. Unfortunately, you will need one of Apple's USB-C power adapters ($ 49 +) and a USB-C lightning cable ($ 25 +) to work. 
Paying 75 dollars in addition to a phone that costs 1.000 dollars for such a basic feature seems a little unfair.
We don't know for sure what kind cable έρχεται με το iPhone X και 8, αλλά στην ενότητα προδιαγραφών "the box" δεν αναφέρεται κάποιο καλώδιο USB-C.
On the contrary MacBook Apple's and MacBook Pro are both reported to have USB-C, so the new iPhones are likely to come with the regular old USB-A cable.
