magsafe

MagSafe is a series of proprietary magnetically attached power connectors developed by Apple Inc. for Mac laptops. MagSafe was introduced on 10 January 2006, in conjunction with the MacBook Pro, the first Intel-based Mac laptop, at the Macworld Expo. A MagSafe connector is held in place magnetically so that if it is tugged (for example, by someone tripping over the cable), it will be pulled out of the port without damaging the connector or the port, and without pulling the computer off its surface. A thinner and wider version, called MagSafe 2, was introduced in 2012. It was discontinued across Apple's product lines between 2016 and 2019 and replaced with USB-C and USB Power Delivery charging. MagSafe returned to Mac laptops with the introduction of updated MacBook Pro models with MagSafe 3 in 2021.
