The MagSafe charger makes wireless charging fast and convenient. The magnets can be precisely aligned with each other on your iPhone 12 or iPhone 12 Pro, which greatly increases the speed of wireless charging (up to 15 watts).
The MagSafe charger is still compatible with Qi wireless charging, so it can wirelessly charge iPhone 8 or later models and AirPods models equipped with a wireless charging box like a Qi certified charger.
The magnetic alignment function is only available for iPhone 12 and iPhone 12 Pro models.
