BQLZR Semiconductor Refrigeration Tablets 62mmx62mm，Heatsink Thermoelectric Cooler Cooling White TEC1-12730 253W Thermoelectric Peltier Semiconductor Clip Cooler

• Operates in 12 volts DC and >30 amps to make it works fluently.
• Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications such as cooling your CPU, video card, NANO Reef, laser diode, CCD camera, picnic cooler, beverage cooler , alternate power sources, or even for your own custom car drink warmer/cooler.
• This device must be used in conjunction with a heat sink to avoid burned.
• Solid state, vibration free, noise-free. When the product is working, the heat dissipation surface must be heat-dissipated, connected to heat sinks, tubes, etc
• Output cooling power: 253W
• 62mm x 62mm x 4.8mm (2.44 inches square, about 3/16" thick)
• The rate of cooling/heating depends on how much power is applied.
• NOTE:1)Don't even think about hooking up 12 volts before putting one or two heat sinks in place. 2)It can get really hot and cold, really fast. Don't burn it up and/or burn yourself.
• If you just want to hold it between your fingers and experience an odd sensation, 3 volts would be enough.
• When the product is used, the cooling surface must be close to the object, and it is best to apply thermal conductive silicone grease
