    Hi,
    this might have been discussed before, but I just cannot find a threat about it:

    May I use my old 85W Brick of my older 15″ for the new unibody 13" Macbook Pro?
    The MacSafe Adapter certainly fits. But is ist safe to use it ?
    Please help

    Thanx from Germany.

    That was quick...

    Thank you, that was a quick and clear reply...

    I am certainly not good with electricity,,, as you can tell.
    So even though it is bigger (85 W vs. 60W), it will not harm battery or the brick?

    It won't harm it, the number on the power adapter is the maximum output, it can be scaled back. I use my 85 watt power adapter from my MacBook Pro on my MacBook Air frequently.
