You can bring this teeny tiny A/C wherever you go

We're approaching the point of summer where an air conditioner set to full blast is a necessity at all times. And now when full blast isn't in the cards—say, your Scrooge-y boss keeps your office at sauna temps—you can still keep your cool, thanks to a teeny, tiny portable air conditioner that costs less than a penny a day to run.

The Geizeer uses a special gel ice pack and a fan to blow perfectly chilled air for five hours without a charge—meaning you could feasibly bring it to the beach or a baseball game on a particularly sweltering day. And it charges with a USB cable, so you could even juice it up with a portable battery if the game goes into extra innings. (Hey, you might look silly. But so do those clowns with portable fans.)

Watch it in action:

You can get your Geizeer here for $109—so a lot cheaper than the clunker that fills your window. (Although it's not big enough to cool your whole house.) The only bummer is you won't have it in your hot little hands until December—when the last thing you want to think about is a cold breeze.
