what is the benefit of the mag safe charger if you have the new power plug in device for the iPone 12?

Hello,

I guess that the only significant advantage is that you don't have to insert the cable into the phone. With MagSafe, you just lay the phone on the charger:

How to use your MagSafe Charger with iPhone 12 models

Good luck.

Well, for me its of no use. It charges my iphone 12 very slow. I have done the troubleshoot with apple on chat, also got the MagSafe replaced but still got the problem. If i was you i wouldn't have bought it. I don't use it anymore. Sad but true it takes almost 4 hours to get to 80 percent from 20. My 5 w brick that came with my Xr charges faster!
