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.

It was discontinued across Apple's product lines between 2016 and 2019 and replaced with USB-C and USB Power Delivery charging.

The basic concept of MagSafe is derived from the magnetic power connectors that are part of many deep fryers and Japanese countertop cooking appliances since the early 2000s in order to avoid spilling their dangerously hot contents.

[15] MagSafe 3 is slimmer than its predecessor and connects to a power supply using a removable cable with a USB-C end.

Since this uses an actual Apple product, purchased legally, manufacturers believe that no licensing agreements are needed (a principle referred to as the first sale doctrine) and no patent was violated.

These chargers were sometimes unsafe or had false specifications in their labelling or malfunctioned: e.g. the LEDs on the connector did not show the correct color.

[22][23][24][25] Many users reported problems with the quality of the construction of the early MagSafe cords, giving the product low marks on the Apple Store's website.

[26] Common complaints included the plug separating from the cord, transformer shorting, and pin springs losing elasticity.

[28] Following the release of a Knowledge Base article, a class-action lawsuit was filed on May 1, 2009, in the US District Court for the Northern District of California's San Jose office, alleging that the MagSafe power adapter is prone to frayed wires and overheating, and as such represents a fire hazard.
