    I just bought a macbook as a replace for my five year old iBook. I was planning on purchasing a second power adapter. I like the size and more rugged connector on the Macbook Air power adapter.

    I have searched around and it sounds like the Air adapter will work with a MacBook but I am not completely convinced. I understand that this adapter will only charge or power the unit but not both.

    Has anyone tried their Air adapter on a MacBook? Could an Air owner tell me the voltage and current rating (outputs) on their adapter?

    dont know the ratings or voltage, but i plugged my G/F's Air power adaptor into my MBP and it not only powered it, but stated it was being charged to so.

    It should work, but it will take longer to charge. I believe the Air adapter is 45w, the MB 65w and the MBP is 85w. I used to have a PowerBook G4 15" that originally came with a 65w adapter. I used an iBook adapter with it which was only 45w, it would power it ok, but sometimes it would stop charging, then start charging, then stop again.

    Bought It!

    As an update I picked up a Macbook Air power adapter. It works great with my Black MacBook.

    The good side of the grass.
    That's funny, my Air charger won't even light or charge when plugged into the MBP. Works fine in the MB though. Maybe cause it's gen. 1 MBP?

    I have used my MBA charger with my Penryn MBP with no problems. It powers and charges the MBP. I do notice the charger gets slightly warmer when used with the MBP than just when used with the MBA.

    I love it since it is so nice to carry around such a tiny charger in my briefcase when I take my MBP out of the office.
