Wireless charging. You have to have electromagnetic induction.
The iron plates, of course, block the magnetic signal.
This is the reason why you can not charge, originally thought with a small iron sheet will certainly affect wireless charging, but just saw on Taobao a times, a magnetic car mount actually also supports iPhone X wireless charging, behind the same with a small iron sheet! Everybody, has anyone ever tried this before? I have been thinking no, so I did not buy a wireless charger, who has used it to talk about it
