    I rec'd 2 power cords with my new Air, one thicker than the other. What is the difference between the two and why are there two?

    They simply slide up and out of the brick. Use the extension for when you need more length or where you cannot use a wall wart style adapter.

    The extension also has a grounding pin whereas the short plug does not.

    Nope. The rounded metal knob that the cord attaches to is how the brick manages being grounded.

    Thank you Pakaku,

    learned something new today! Strange somehow that the plug on the brick directly is not grounded though.

    It's pretty simple. Use the longer cord when the short one alone isn't long enough.

    @chabig's answer is of course correct - use the long one when you need a longer cord :)

    Personally, I leave the long cord plugged in at home, with the "Brick" located for convenient access. When I'm going to be traveling overnight & want to take my MacBook Air, I slide the brick off the cord and put it in my overnight bag, where I keep the "duckhead" adapter, cord stays behind. Keeps me from having to reach down behind the dresser where the long cord is plugged in.

    It probably has something to do with the compact form, since you can fold the prongs in. I guess there wasn't enough room for an elegant ground-prong solution.

    The pins don't fold at all on the NZ one (they're angled, not parallel like a US plug) but there are still only two.
