Works with any MagSafe device, so also with iPhone 14. However, it should be noted that the double-sided adhesive is very thin, i.e. it cannot be pressed and attached to ANY curvature. I recommend the holder, if at all, only if the surface on which it is to be attached is really 100% flat.

I don't know, but it works perfectly with the iPhone 13. But it is only a holder. No charger! Greetings
