High Quality Content by WIKIPEDIA articles! MagSafe is a proprietary magnetically-attached power connector introduced by Apple Inc. on January 10, 2006 in conjunction with the MacBook Pro at the Macworld Expo in San Francisco. The MagSafe connector is held in place by a magnet so that if it is tugged on, for example by someone tripping over the cord, it will pull out of the socket safely, without damaging the connector or the computer power socket, or pulling the computer off of a table or desk. MagSafe is similar to the magnetic power connectors that many deep fryers and Japanese countertop cooking appliances have in order to avoid spilling their dangerously hot contents. Apple exclusively owns US Patent No. 7311526 ("Magnetic connector for electronic device", issued in 2007) and does not license the MagSafe connector or the patent.
