Spec Sheet
Where can I find the spec sheet for this online?

Power....
How do you power this? I have 2 nice aluminum heat sinks on it, and am powering it with a 9v battery but it does not do anything. My battery gets hot, so I am assuming that it is drawing current.....but when I measure the voltage of the battery when it is connected it reads around .4 volts and immediately returns to around 8.2 volts afterwards. Help??? Editors Note: You can not get enough current out of a 9 volt battery. You need several amps to power this. Have a look at the spec sheet

'Cool' Little Device!
This works exactly as advertised. I love it, things like this get the inventive juices flowing so to speak. However, if you don't have the supplies to cool the hot side, I would suggest buying the other peltier model, as it already has heatsinks attached! Would buy again!

Power requirements
The power requirements are clear. Multiply the Imax (max. amps) by the voltage. For example 12 volts X 8 amps = 96 watts.
However, on startup the amps are a little higher than typical ratings. I recommend a power supply of at least 125% of power consumption.
Stacking TECs works, but one should stack progressively larger or smaller TECs since the hot side is multiples more efficient that the cold side.
Example: If using TECs for cooling a CPU, put the cold side of a small TEC onto the CPU chip, put a larger TEC ontop of that, etc.
I highly recommend an aluminum plate of about 1/16" thickness between each TEC, but always as large ase the upper TEC.
Example: 1st TEC is 20mm square, second TEC is 30mm square, aluminum plate between the two is 30mm square, etc.
Now, thermal shut-off of TECs using switches such as bi-metal switches is very hard on the life of TECs.
To regulate either the hot or cold side of a TEC without harming the life of the TEC you should use a pulse width modulator. I recommend the PWM's sold specifically for this purpose that you can buy at TETech.com for about $100.00. The same PWM can be used for either the hot or cold side by simply changing a jumper wire.

hat transformer will power this alone
To use one of these alone, what size power supply do you need? Not the computer power supply, I mean if it is just running this and nothing else?
