You can magnetically attach your iPhone to an Apple MagSafe charger and your device automatically charges wirelessly. Thanks to the built-in magnet, this charger stays firmly on the back of your iPhone. This only works with an iPhone 12 or newer. After 1 hour of charging with a MagSafe wireless charger, the battery of your device is 50% full. This takes 1.5 hours with other wireless fast chargers. The Apple MagSafe charger doesn't work well with older iPhone models. Want to charge your Apple Watch or AirPods as well? Choose a MagSafe charging dock.
