Thermoelectric coolers (TECs or Peltier elements) create a temperature differential on each side. One side gets hot and the other side gets cool.
Perfect for application requiring heating or cooling such as small DIY refrigerators, custom drink heaters/coolers.
After turning on the device, the hot side will heat quickly, and the cold side will cool quickly.
The maximum power (voltage x current) applied to this device must not exceed 60 Watts.
