Apple 45W Magsafe 2 Power Adapter for MacBook Air

This is a genuine Apple 45W charger which has the Magsafe 2 magnetic connector protecting the 45W power adapter as well as the MacBook Air computer. The design of the Mac Magsafe 2 power adapter means that if someone walks past your MacBook Air whilst it is plugged into the mains power and kicks your Magsafe 2 mains adapter cable then due to the fact that it is only connected via a magnetic link it will just simply disconnect from your MacBook Air.
