TEC1-12706 72W Semiconductor Thermoelectric Peltier Cooler Heater - White

Pros: Super fun. Really cools things down. Connect it to an old laptop power supply. I'm using one that gives 15v at 3.5A.

Cons: Without a heatsink, fan, and thermal compound, the whole thing gets really hot. If you're buying this, buy them at the same time - any CPU heatsink/fan combo should work. Totally don't understand the science behind it.

Other: From supermarket room temperature beer to ice-cold refrescante in 2 minutes? You bet! But that's the only use I can think of.

Pros: Excellent cooler or warmer! I tested with an old fountain that used on a router burned and cooled well. Now I need TWO CPU cooler to the heat exchange, on both sides of the peltier, and make my mini fridge. Pt-BR Excelente resfriador ou aquecedor! Testei com uma fonte velha que usava em um roteador queimado e resfriou bem. Preciso agora de DOIS cooler de CPU para fazer a troca térmica, de ambos os lados do peltier, e fazer minha mini geladeira.

Cons: Could indicate kits with cooler and cooler to manufacture portable mini refrigerators. pt-br Poderiam indicar kits com cooler e caixa térmica para a fabricação de mini geladeiras portáteis.

Other: Excelent!

Pros: works even with 3.2 volts 2000ma batteries but drains them too fast but anyway i tryed it with all most drained battery . they are arroun 4.5mm in size .

Cons: im not actully using them for now because im busiy with somethings else , just did alot of tests for now and placed it back. so i can say anything about ist long time stability.

Other: good product wide range of working voltage voltage chances its effectiveness anyway. deserves its price clearly .

Pros: with a voltage of 2 volts consumed the initial current is about 2.5 amps, which descends about 2 amps when the temperature exceeds 50 degrees.

Cons: Is relatively easy to achieve a temperature difference of 40 C ° between two sides of the Peltier device. For testing I used two identical heat sinks equipped with fan, located on each side of the Peltier cell. It is a means inefficient cooling a CPU but is effective when it does not matter 24 watts consumption.

Other: Not efficient but effective.

Pros: well, it's much much cheaper than anything you can find on retail. The device came with silicone sealed sides,.that is very good for my application. Easy to use, better way to use is have a constant current drive.

Cons: mine came with a corner dented. LUckily the metal elements inside were not damaged. the maximum power is 50 watts, not 72. please check datasheet, or you will kill it before time....

Other: nothing, really. A cool device ad a cheap price. Perfect for stydy or for diy thermally controlled small environments
