USB powered, so you don't need a power adapter.
Can both heat and cool.
Pretty effective to be USB powered. I'm not sure how much power it draws though, but USB 2.0 only allows 500mA which is 2,5W.
Really small. Can only hold a 0.33L can. However it's easy to take it out the cooling system if you want to put it in a bigger housing.
The box says it looks cool on every desktop. I don't agree too much.
I studied the fridge and it works pretty simple. Under the metal plate there's a peltier element, and when it's connected to 5V it draws heat from the one side and over to the other side where the fan blows the heat away. If you turn the switch over to heat, the voltage is reversed and it draws heat the opposite way.
It advertises that it's compatible with Mac and PC. I figured it's also compatible with my Playstation 3 and Xbox 360.
