Apple allow fast charging on the iPhonw X, however, they kindly can’t supply the USB-C to iphone cable when purchasing the iPhone X due to their competitive pricing at $1700 😳🙄.
These cables usually run at about $30 from Apple. Pair this up with something like the Blitzwolf USB PD USB C adapter here we might be able to experience what cheaper android users have been enjoying for a while.
MFi?
