Mike, you are absolutely correct in your analysis of these mini-swamp coolers. But their ability, under the certain circumstances cannot be denied. I lived in Phoenix AZ for a few years, where these were used in a few homes as rooftop coolers. On a larger scale than the ones hyped in recent scams, these can work semi-efficiently in a hot and very dry environments. Under the right conditions, they are able to do something a fan and mister will not, and that is cool a larger area, like a room.
Agreed! Under the right circumstances the rooftop evaporative coolers can work quite well. But these tiny desktop units powered by a USB port on your computer are essentially a misting fan.
I’d love to see some A/C reviews or a survey of the current cooling technology landscape. The wife and I are experiencing our first really hot weather camping—consecutive 100+ degree days and 80+ degree nights—and I’d love to get ideas on how we could improve the experience in future. Our absorption refrigerator is struggling much more than our A/C units, though.
Thank you so much, Mike! I thought this was kinda like the coolers that cool X number of degrees below room temperature. I still have one I used in a big rig. Worked fine there, but the rig was always in the 70's.
Thanks Mike! Now what’s the scam about free solar panels?
A wet cloth placed on your neck and a fan would do just as good if not better.

You’re referring to the Peltier Effect, which is the technology in semiconductor coolers. They on drop the temperature by maybe 20 degrees, so they work as a cooler, not a true refrigerator. I’ll cover more on the different types of coolers later. https://phononic.com/resources/how-thermoelectric-cooling-uses-the-peltier-effect/#:~:text=The%20Peltier%20effect%20refers%20to,current%20as%20well%20as%20reversible.
