iPhone charging pad
When a charging pad is advertised as 20w is the pad itself 20w when plugged into a usb outlet or does the pad cord have to plugged into a fast charge adapter plug to really be a 20w pad?
iPhone X, iOS 16
It would help if you identified the exact charging pad you are referring to in your post. Would it be this one?
If so, then to get fast charging, you would need either a 20 or 27W power adapter, for that.
