USB Water Cooled Fan

Get ready for summer with this water based USB fan. This is a small, portable fan houses a sponge so when air is drawing over it, cooler air comes out.

I’ve seen on the web some call this a portable air-conditioner, and I think that is unrealistic. However; if you want cooler air than what is in your office or room, this will do the trick.

I’ve read a couple of reviews from Amazon about the fan it people say it’s quite and does a good job of sending a stream of cool air.

You can run the fan directly from USB, or charge the battery for portable use. For example, on a hot summer day watching your kid play travel soccer or softball.

The USB water cooled fan comes in three different colors and is available now, before the heat of summer hits! At the time of this writing the USB fan was only $15. Almost a no-brain-er just as a try.

The program provides a command line interface over the serial port that you can use to program the message and set other options like speed and the delay between messages.
