The power adapters with the MagSafe plugs? Yeah, for the most part. They have 3 different current outputs, but all will work safely. The lower wattage ones will charge more slowly, or in the case of a Macbook air 45 watt PS trying to power and charge a MacBook Pro (which uses the 85 watt one), it might actually not keep up, and the battery will still drain VERY slowly. I don't know this for a fact.
