    Funciona ya con 1.5 V. Empieza a enfriar de verdad con 5 V y da el máximo a 12 - 13 V. Es importante montar un radiador de cobre y de dimensiones generosas en el lado caliente. Con 12 V he conseguido de -15 ºc a -17 ºC en el lado frío. Como generador de corriente, funciona pero lógicamente genera muy pocos mA.

    @12 volts with fan running, It only use 3 + amps. You just need to use a better HSF. Stock/generic HSF from Intel/AMD cpu is Not enough to draw the heat.

    Good device, but does not generate the stated voltages

    This is a great unit but it's output as a voltage generator is not what is presented in the description. I have put large temperature differences across the unit and it never generates a voltage over about 0.8V. I needed 2 units in series to power a 5V boost converter. Once the converter triggered, the thermoelectric device did a great job of powering it and an attached LED lamp for a long time. These are high quality units, but do not generate the voltages described. In the picture, I used a ice

    Brutally working well. It is able to work with very high efficiency at low power consumption. Good buy.
