    This is the spare/replacement power cord/charger for the Macbook Pro 15" and 17".

  • this is for the 2011 and before MacBook air (not for use with any other). you may have bought the computer in 2011, but if it was before WWDC 2012 then it has magsafe 1. you can use this and have the magsafe to magsafe2 adaptor to have a charger that is more convenient to use. Moral of my blabberings is do not use with anything but a MacBook air from 2011 and before

  • It charges your macbook pro.
