MagSafe accessories attach to your iPhone with a MagSafe magnet. At this time, MagSafe accessories only work with the iPhone 12 series. There are several different types of accessories. A MagSafe charger not only stays securely on your iPhone, but also charges your device 1.5x faster than standard wireless chargers. Store your cards in your MagSafe wallet and leave your wallet at home. Cases with MagSafe are especially useful if you use other MagSafe accessories, such as chargers and card wallets. The magnet inside your MagSafe case keeps those accessories securely in place. Cases without a magnet are less likely to hold accessories in place.
