    Does anyone know which of these is the right power adaptor for the new 11.6" Macbook Air, as I would like to get a second power supply to keep at work...

    The problem is that on the Apple UK Store there are two different 45w magsafe power adaptors for use with the macbook air at different prices!

    There is this one for £49:

    And this one for £65:

    Is there a difference, and does it matter enough to pay an extra £16 for the more expensive one??

    They'll both work. The cheaper one was for the 1st generation MB Air, which I have, and it works fine on my new 11.6" MBA. In fact, I have an older adapter from a white MB (with the rectangular plug), and that works fine too. It's a bit bigger in size (being 85W max) than the ones for MBA (45W max). But if you can find a used one for a good deal, go for it.

    The 2nd one that is 65 looks more like mine... I'd go with that. The first ones magsafe plug looks different.

    You can use anything 45W and above for the MacBook Air.
