    My iPhone X comes tomorrow and I'm wanting to order the following fast, wireless charger from Amazon but it doesn't come with a power adaptor.


    The specs on the charger say it's 10W max but I've read that the fast charging feature might require more than 10W on the iPhone X. I was thinking about using a 10W iPad power adaptor to use on the wireless charger but I'm wondering if it'll do any good with fast, wireless charging?

    Any suggestions?

    Transferring power over the air is terribly inefficient and will burn extra overhead. As energy conscience and blue as Apple is... I’m quite shocked they went in on the wireless charging.

    I recommend you stick strictly with the ones who promise compatibility with iPhone fast charge... thats:
    Mophie and Belkin from Apple Store are safest bet.
    There is also one specific model of RAVPower on amazon that claims support.

    Each comes with an appropriately rated power adapter.

    29w charger for usb c and a usb c to lightning cable for fast charging is my understanding of what you need

    as far as i know iphone x doesn't support fast wireless charging

    It really isn't quite wasteful enough to declare it a detriment to the environment - we're talking a handful of watts here.

    The description clearly says fast charge for Samsung, standard slow charge for iPhone. You need to read the details to understand what you are getting.

    Wireless is about 70% the efficiency of wired. The cases Apple offers are likely more environmentally unfriendly than this feature is... perspective.

    Get a USB c to lightning cable. Get the proper plug for USB C fast charging. This will sort those issues for you.

    I haven’t seen anything that says iPhones will use QI at a rate over 7.5W iirc. In either case, if you’re going the cheap route any 2.1A charger will suffice for a 10W QI pad. Won’t be as quick as wired, but will work just fine overnight or to keep a charge topped off at your desk if you live in a horrible reception area.

    The mophie and belkin from the Apple store do 5w with the iPhones right now. Supposedly a future iOS release will support 7.5w wireless charging which those both are ready to do. So the only thing holding it back is iOS itself right now

    So is Apple just limiting the charging speed until the release of its own charging pad? If not, why handicap the capability of its premium device?

    I looked into this very briefly. The Amazon reviews said their iPhones 8s didn't fast charge. They also mentioned heat. Now, I don't want a hot pad, so knowing these things I went with a Ravpower $15 regular wireless, that people say doesn't heat up. I figure I'll wait for a better grip on the whole thing, before I spend over $20. So it will be an overnight thing. Who knows.

    No wireless fast charging. Need a usb-c ac adapter and usb-c to Lightning to plug in fast charge.
