I worked at a hotel in 2007 and folks left their laptop chargers all the time. Every so often the managers would let us raid the lost and found for stuff that hadn't been claimed. Well, I found this in there. I re-found it today going through some boxes of stuff in my apartment. I have no use for it as I don't have a MacBook. It is the official Apple brand. I have no reason to assume that it doesn't work, as the previous owner was likely using it before they left it. I see that these aren't cheap on Ebay, but I'll take the first reasonable, sub-Ebay level offer.
