The refrigeration unit operates in a state where one side cools while the other heats. It is essential to provide good heat dissipation for the heating surface during operation. It is strictly prohibited to power on the unit for more than 2 seconds without heat dissipation, which could lead to overheating and potential damage. The buyer assumes all responsibility for such damage!

Installing a heat sink must involve applying thermal grease.

The power of the product does not meet the original specifications.

Please choose other stores' original products if you require high quality. Please do not compare the quality with the original products. You get what you pay for. Those who play with high power should not purchase!

Please purchase samples first if you are a bulk customer.
