Description:

1.Get ice cold in minutes or heat to boiling by simply reversing the polarity.
2.Used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer / cooler. 
3.Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts.
4.Must be used in conjunction with a heat sink to avoid burned. Hot side needs heat sink all the time. 

Please Note:

1.Under cooling mode: Red wire to positive, black wire to negative. the surface with model number is cooling side.
2.When heating, just need to change the current polarity; when cooling, switching power supply is needed.
3.During installation, keep thermoelectric cooler clean, and apply the heat-conducting silicone grease evenly over both heating and cooling surfaces.
