About this product
A thermoelectric Peltier cooling kit moves heat from one face of the module to the other when DC current is applied, creating a cold side and a hot side. Such kits are used for small cooling boxes, cooling electronics and temperature control experiments. The hot side must be fitted with a heat sink, and often a fan, to carry away the heat it pumps.

Frequently asked questions
Why does the hot side get very hot?
A Peltier module moves heat and also adds the electrical power it consumes as heat. Without a large enough heat sink and airflow on the hot side, the module overheats and cooling drops or stops.
Can it be powered from USB or a battery?
The listing does not state the rated voltage or current. Confirm these from the module datasheet before connecting any supply.
