    I've been using my iPad charger to fast charge my iPhone 7 and it charges super fast. Is buying a new charger necessary for the X or can I use my iPad Pro 10.5 charger?

    Also, any harm in using the iPad charger on the 7? I noticed if I'm on a call and using the phone while 'fast charging' it gets really warm. I don't do it every night, just when I need juice quick.

    Thoughts?

    You can still use the ipad charger. No need to buy anything else.
    It will still charge it faster than the regular slow plug charger that comes with the phone.

    But if you want the real fast charging you will have to buy the 29watts usb c charger, you will also have to buy a usb-c to lightning cable. Fast charging is working on the iPads pro, and will work with the iPhone 8 and iPhone X.
    I still charges my 7plus with it and i get the same speed as the 12w charger from the ipad pro. All other ipad comes with 10w chargers

    I really wonder about that.
    How much faster than the ipad charger the "real Fast" charging option is that I have to buy a new charger and new wire etc...
    Its already very fast with my ipad plug, what am I doing it for another 2-3 minutes quicker?
    Guess we'll have to wait and see.

    I kind of wonder this too. The quoted speed is 50% in 30 minutes, and although I haven't checked with a stop watch I think my iPhone 7 charges at very close to that speed using this Anker charger if it is left alone:

    I will be very interested to see some numbers if someone who gets an iPhone 8 decides to stage a charging "drag race" of sorts with the various Apple USB-C chargers (29w, 61w, 87w), or if we will quickly see some 3rd party solutions from Anker, Griffin, etc. etc. that can fast charge the 8.

    That's what I was thinking too.
    I get from 20% to 70-80% within a half hour now with my 7 Plus.

    Really hoping that we don't see any exploding iPhones with all of this fast charging. :(

    Apple will sell you a USB-C female to USB-C male dongle that fits between the cable and charging brick to provide extra charging safety. It reduces the charging to 5 watts. Costs $29.

    From the Daring Fireball review:

    The iPhones 8 also now support “high-speed charging” when you connect them to a Lightning cable attached to a high-wattage charger. In the box, both the iPhone 8 and 8 Plus both still come with the same rinky-dink 5-watt charger that all iPhones have shipped with since 2008’s iPhone 3G. iPhones have long charged faster when connected to one of the larger 10- or 12-watt chargers that ship with iPads.4 I went out and bought one of Apple’s 29-watt chargers that ship with the MacBook ($49 bucks, not cheap). I also bought a USB-C to Lightning cable ($25 for 1 meter, $35 for 2 meters — also not cheap). Anker makes a 30-watt USB-C charger that sells for under $30, but I figured I’d test fast-charging with Apple’s kit.

    The bottom line: it’s faster, yes, but not that much faster. I ran the iPhone 8 battery down until it powered off. I plugged it into the 29-watt charger, and got the following results: after 15 minutes it was back to 27 percent, at 30 minutes it was at 54 percent, and at 45 minutes it was at 72 percent. But then I did the same thing with my year-old iPhone 7. After 30 minutes it was at 43 percent, and at 45 minutes it was at 65 percent. (I didn’t pay attention to where it was at after 15 minutes.) The iPhone 8 does charge faster than an iPhone 7, but not by much.

    Good info.
    So if you're already using an ipad 10W or 12 Watt charger spending another $80 for all that is probably not worth it.

    I was getting ready to pull the trigger, but I think I'll hold off, too

    I also read a similar thing if I’m not mistaken from an iphone 8 review by buzzfeed, the reviewer mentioned he/she had the same charge result with the 7, even webt in to say “did the iphone 7 suddenly got fast charging”

    I still use the 5W charger most of the time (overnights). I think the slower charge will give more longevity to the battery.

    Overnight I also use the regular charger since it doesnt matter if it charges slower then.
    But if I want a quick boost during the day I go with the higher/faster charging option.
    The better battery longevity idea with a 5W plug is a myth.
