Apple 60W Magsafe 2 power adapter for MacBook Air
This genuine Apple 60W charger has the Magsafe 2 magnetic connector which protects the 60W power adapter and the MacBook Air computer. The design of the Mac Magsafe power adapter means that if someone walks past your MacBook Air while it is plugged into the mains power and kicks your Magsafe mains adapter cable then because it is only connected via a magnetic link it will simply disconnect from your MacBook Air. This will therefore minimize undue strain on both the Magsafe power port and MacBook Air power cable
Apple 60W mains adapter will charge your MacBook Air battery while turned on, turned off or in sleep mode. If you have no battery fitted then it will simply power your MacBook Air.
