The Cooler Module starts working when powered on with rated voltage 5V and rated current 1A. Featuring a small size of 30*30*5mm, instantaneous refrigeration, stable performance, no noise, and vibration, it can reduce temperature to -20℃ at most. It can be used in the environment with limited space, high-reliability requirements, and no refrigerant pollution or used for making portable refrigerators/incubators, hot and cold water dispensers, and cooling electronic devices.

Note:

1. The side with words is for cooling, and the side without words is for dissipating heat.

2. Heat side requires a heat sink or water-cooled heat dissipation device all the time, otherwise, there is a risk of burnout.
