pocket air conditioner

We're having the first serious heat wave of the summer (about 97-100 F) and I'm sitting here getting moderate relief with my new pocket air conditioner. B. ordered us a couple of these. It's about 7 inches by 5 inches, 6.5 inches high, and it runs on a battery (recharged by plugging it into a USB port) and a small bottle of water that snaps upside down into a holder. When I turn the fan on, a faint stream of coolish air comes out the back and makes a modest attempt to refresh me. Really, it's at least as comforting as pitiful meows from a cat or two.
