Features: <br>1. Air cooling device, it is not used to cool the water but for heat dissipation by means of water circulation. <br>2. Can be used in small space cooling, pet air conditioner, learning the principle of semiconductor refrigeration and more. <br>3. Refrigeration effect depends on the size of the cooling space, ambient temperature, heat insulation, sealability, etc. <br>4. With strong resistance to low temperature, durable with long service life. <br>5. Simple structure but good practicability. <br> <br>Specification: <br> <br>Red Wire: "+" <br>Black Wire: "-" <br>Optional Type 4 chip cooler 6 chip cooler <br>Power Supply DC 12V 24A DC 12V 36A <br>Power 280W 420W <br>Size 12*6.6*9.5cm / <br> 4.72*2.60*3.74in 16*6.6*9.5cm / <br>6.30*2.60*3.74in <br>Weight 611g/21.5oz <br>841g/29.6oz <br> <br> <br>Package list: <br>1 * Cooler <br> <br>Note: <br>1.
