MagSafe is a proprietary technology developed by Apple that refers to a magnetic attachment system used primarily for charging and accessory alignment. The term has been used for two different things over the years, depending on the device:
π 1. MagSafe for MacBooks (2006 β Present)
-
Originally introduced in 2006, this version of MagSafe was a magnetic power connector for MacBooks.
-
It snapped into the charging port magnetically and would detach safely if pulled, preventing laptops from being dragged off desks.
-
Discontinued in favor of USB-C for a few years, but reintroduced in newer MacBooks (2021 and later) as MagSafe 3, offering faster charging and the same magnetic safety.
π± 2. MagSafe for iPhones (2020 β Present)
-
Introduced with the iPhone 12 series in 2020.
-
It's a magnetic ring built into the back of the iPhone (and compatible cases) that aligns accessories like:
-
Wireless chargers (e.g., MagSafe Charger)
-
Wallets
-
Battery packs
-
Mounts and stands
-
-
MagSafe ensures precise alignment for wireless charging (based on the Qi standard, but with magnets for better efficiency).
