So I been reading up on the fast charging for my X. Everything I’m finding online talked about the Qualcomm 2.0 and that I will need to buy a usb-c to Lightning cable and a usb-c 29w power pack. So I was looking through my power packs and I found a Samsung usb fast charger from my work note 4 which after searching says it also is Qualcomm 2.0. So I tried my Apple usb to lightning and the Samsung fast charger and it charges. I will do a controlled test once my phone is down to 20 percent and see how much it charges in 30 mins. I will post my findings when I complete it. Any thoughts please let me know.
