Review on Portable Evaporative Cooler: USB Rechargeable, Stepless Speed Control - Ideal for Home, Office, and Outdoor Use by Jeffrey Crutcher

First of all, it is very beautiful. I'm pretty sure I ordered white and got yellow. I regret not just for the aesthetic value. However, this is basically a very expensive fan. The cooling aspect only seems to work if you're standing directly in front of it and have water in a very small compartment. The instructions say to dampen the inner sponge, but be sure to dry it off before returning to the fan or you'll end up with a puddle on the table. It's not the loudest fan, but it makes a whirring noise and is louder than me. would have liked. In summer I'm ready to deal with the noise, not the heat. The charge doesn't last long. Its portability in the sense that it is easy to move around. However, it is better to use it when connected to the network so that it does not die.
