Peltier Air Cooler DC 12V Thermoelectric Semiconductor Refrigeration Dehumidification Equipment DIY Kit 144W 15A for Small Refrigerators Air Conditioners Pet

Hi, Did you use this unit (https://www.amazon.com/Dual-core-Semiconductor-Refrigeration-Thermoelectric-Dehumidification/dp/B074TX9CQC) to dehumidify your 70L wine cooler? If so, did it spike up the temperature inside the cooler much while running? I also notice that it seem you did not have to drill hole at the back of the wine cooler, did you just leave the wire through front door and let the front door's rubber gasket to help seal everything?
