    Swapping power adapters is generally a bad idea.

    Especially when the laptops have different power requirements

    The MBP power brick will work fine on both the MBP and MB.

    The MB power brick will run (but isn't supposed to charge) a MBP.

    Apple Says Differently...

    I could have sworn I read that it was officially fine to use both power supplies interchangeably, but Apple says differently:

    Use only the power adapter that came with your MacBook Pro computer. Adapters for other electronic devices (including other MacBook Pro models) may look similar, but they may affect your computer’s performance or damage it.

    I've always used PowerBook and iBook adaptors interchangeably, though; it's just more convenient.

    Yeah, I thought I read something straight from Apple that said it was OK to switch them around, but now when I google, I only see weblogs and the such that say it's OK.

    One guy did notice that the output from both the MB and MBP bricks are the same, which makes me wish I knew more about electricity to understand what the different wattages really mean. :D
