Apple's MagSafe Charger combines a 15W Qi-based wireless charging puck with a ring of magnets that snap precisely to the back of any iPhone 12 or later. The 1-meter braided USB-C cable feeds power from a 20W (or higher) USB-C adapter sold separately, while the polished silver puck stays cool thanks to efficient inductive coil design. Compatible MagSafe cases keep alignment perfect without removing them.
