MagSafe
First introduced in 2006, MagSafe is a proprietary type of magnetic connection used to charge Apple iPhones, and formerly, MacBook laptops. Magsafe was discontinued in 2019 on laptops and brought back in 2020 with the announcement of the iPhone 12. The new iPhone model has a magnetic back to obtain a more secure connection with wireless chargers and proprietary iPhone 12 accessories. iPhone MagSafe chargers can transfer 15-watts of power, equivalent to the fastest Qi wireless chargers available, which are still supported on iPhones.
MagSafe was originally used by Apple MacBook laptops. Variations of the proprietary cable could be magnetically attached to charging ports, providing a secure connection that detaches easily in case of an accident. The MagSafe connection was used on every version of the MacBook, including the MacBook, MacBook Air, and MacBook Pro models. In 2019, the last MacBook featuring a MagSafe connection was discontinued in favor of a USB Type-C connection, which transfers the same 20 volts, but can also transfer data.
