Working current: Imax = 4.3-4.6A (rated at 12V) Rated voltage: 12V (Vmax: 15V starting current 5.8A) Cooling power: Qcmax 55W Working environment: temperature range -55 'C ~ 83'C (high ambient temperature drop directly affect the cooling efficiency) 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 own custom car drink warmer/cooler. Since they consit primarily of semiconductor material sandwiched between ceramic plates and have no moving parts These devices must be used in conjunction with a heat sink to avoid burned Each device is full inspected and tested Fitted with 6-inch insulated leads
