When the weather is warm, and we need some relief, you can’t do much better than a handheld or miniature fan.

The short answer is anywhere it’s hot. There are seemingly endless applications for a great portable fan, though. They’re perfect for everything from day trips to theme parks, the zoo, the beach, or the pool, camping trips, road trips, outdoor runs, hikes, and everything in between. 

Even a day of errands when it’s sweltering outside is a great time to break out the portable USB fan for some cooling relief while at the supermarket, post office, pharmacy, or anywhere else you wind up.

Even the most powerful air-conditioning units in a home will struggle when temperatures are reaching astronomical highs, so a mini fan follows the same scientific principles present here. No, you won’t get total relief when the sun is beating down, and it’s flirting with record highs, but you will get some cooling effect. 

For better results, try purchasing two fans to run simultaneously or bring an ice pack to place near the fan blades. This will chill the air and make the fan’s already potent effect even greater.

Don’t sweat the small stuff, and get a small fan to give you big relief today. You can find plenty of great desktop, portable, and USB-powered fans to use anywhere and everywhere. Here are some factors to consider when picking the best USB fan for your purposes:
