Bonus Kbase Article of the Week: How to use your MagSafe Charger with iPhone 12 Models »

Apple Support:

Your MagSafe Charger is designed to work with iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, Apple MagSafe accessories, and Qi-certified devices and accessories.

Some additional details:

  • Don’t place credit cards, security badges, passports, or key fobs between your iPhone and MagSafe Charger, because this might damage magnetic strips or RFID chips in those items. If you have a case that holds any of these sensitive items, remove them before charging or make sure that they aren’t between the back of your device and the charger.
  • As with other wireless chargers, your iPhone or MagSafe Charger might get slightly warmer while your iPhone charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone or MagSafe Charger could get warmer and charging could take longer after heavy use. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.
  • Your iPhone won’t charge wirelessly when simultaneously connected to power via the Lightning port—instead, your iPhone will charge via the Lightning connector.

And this gem:

If you keep your iPhone in a leather case while charging with your MagSafe Charger, the case might show circular imprints from the contact.
