Description :

Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your owncustom car drink warmer/cooler.Since they consit primarily of semiconductor material sandwiched between ceramic plates and have no moving partsThese devices must be used in conjunction with a heat sink to avoid burnedEach device is full inspected and tested
