    I just picked up my custom MBA 13"(i7/8GB/256 GB)

    I have an extra magsafe 2 adapter (85W) at home for my work Mac.

    Is it safe to use on the new MBA ? (MBA came with 45W)

  2. macrumors 68000

    Yes but it will not charge any faster as it will only draw 45W.

    You can use any larger MagSafe than the one that came with your Mac, but it isn't recommended to use a smaller MagSafe (ie it isn't recommend to use a 45w on a 15" MacBook Pro that came with an 85w)
