Save your money when you see ads for cheap “personal air coolers” on TV

But this natural cooling from moisture evaporation only works in dry climates

There are a handful of good products to find in corny TV infomercials, but it’s no surprise to anyone that many of them are junk or outright worthless. I spent a good chunk of cash on a “freezing heat” soldering iron that supposedly only worked when you touched it to metal or to the end of a long wire of lead solder. Unfortunately, the tiny induction gas furnace in the device wasn’t strong enough to melt solder, so it never really worked no matter how many times I tried the wretched thing. I even looked at forum posts as recent as a few years ago plus people are still complaining about these bad things over 10 years after they were first released. But there are equally bad products with the infamous “as seen on TV” label nowadays. For instance, our frustratingly naive sibling was harping to me Last yearabout this $20 “portable air conditioner” that she had ordered from a TV commercial. I looked it up plus discovered that her $20 “portable air conditioner” is really called a “personal air cooler,” plus it’s nothing more than a micro-sized evaporative cooler. Evaporative coolers use a straight-forward fan to push air through a wet medium, thus causing the moisture to evaporate into the air, thereby dropping the temperature in the process. But this natural cooling from moisture evaporation only works in dry climates. My sibling was under the impression that she could take this tiny little evaporative cooler camping plus get air conditioner inside the tent. Since our outdoor humidity here hovers above 75% in the summer, the little “personal air cooler” isn’t even going to work!
