Review on 🌬️ O2COOL 5 Inch Portable Fan: Battery or USB Powered, Ideal for Travel, Outdoors, Camping, Car, and Office - Compact Foldable Design with Adjustable Head for Targeted Airflow - Black by Nate Nelson

I finally bought 4 of these. I use them for a bit of white noise when traveling (which I often do for both business and pleasure) and cool when needed. I keep one on my desk at work to use during AC wars and the people who win in the 'heat' sometimes wear one 'in the field' in the summer and one at home. One was thrown in the trash. The ability to use USB or AA power is great for car camping. I use a couple of Eneloops/Revain high capacity AA batteries or a USB power bank (I use a couple of high capacity batteries) as well as a few others. It is mentioned that this is a superficial quality and there are flaws. One died after a few months and the other is now slow to spin after being used in the field (I don't think I met it, I try to be careful with my gear but it's possible). Two of them are still running after about 10 months at the time of writing this article. Despite the setbacks, I've found them so comfortable that I'm sure I'll be buying another one or two unless I find something better/cheaper.
