    Can I use my MBA's charger to charge my Macbook 7;1?

    I don't think so, IIRC, the MB needs a 65W charger and the MBA uses a 45W.

    This should answer most, if not all, of your battery questions:

    I was at a clients office with my MBA and when I left there I forgot my charger. A coleague of mine went there the next day, he's got a 17" MBP and just so happened he forgot his charger at home, so he used mine.

    It worked. Under light usage, the main problem is going to be a very slow charge coupled by a pretty warm adaptor being run at it's max capacity for an extended period of time. If the laptop is off, and you just want to charge it, there shouldn't be an issue at all. I certainly wouldn't use it if you're doing anything heavy though. That's asking for trouble. There's a reason why they come with higher capacity chargers.
