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