Description of WINOMO TEC1 12706 Thermoelectric Peltier Heatsink
Material: Ceramic. Size: 4 * 4 * 0.36cm/1.57 * 1.57 * 0.14inch(L * W * H). Rated voltage: DC12V (Vmax: 15V). Cooling power: Qcmax 72W. It gets ice cold in minutes or heat to boiling by simply reversing the polarity. It can be used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler.
Through trial and error I found that this product is simply not worth the investment. The cooling capabilities are severely lacking and fail to meet basic expectations. Additionally, the installation process is overly complicated and time-consuming..
They worked great but one of them arrived broken after delivery. They were cheap so I'm not worried about that but they should be packaged in a way that this doesn't happen. But overall great!
