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

The Apple MagSafe power adapter's 1-Wire communication chip is located inside the MagSafe connector itself; the cable does not carry the data

The first generation MagSafe (also referred to as MagSafe 1 after the introduction of MagSafe 2) has connector pins that are designed so the rectangular connector can be inserted in either orientation. Originally the connector was T-shaped, with the cable directed straight out; later it became

In the first-generation connector, the inner large pins are V+ (14.5 / 16.5 / 18.5 / 20 V DC). Measuring with no load will give 6.86 V DC for MagSafe and about 3 V DC for MagSafe 2; the full voltage is provided after a ~40
