Testing two powerful Peltier coolers: TEC2-19006 and Heke Tech CL-C067

Описание: In this video, I test two "new" Peltier coolers. I wanted to get some more powerful Peltier coolers for a project and I found these two devices on Aliexpress. According to the parameters published on the sellers' site, these devices are able to reach below -30°C without any issues while consuming relatively low power.

Unfortunately, only the TEC2-19006 seemed to be fulfilling the promises made by the Aliexpress pages. The Heke Tech performed poorly.
