Editor's Notes

June 13, 2019:

We added two quality models to the list: the AceMining Office and the Elechomes Table. Even though the AceMining option is a clip-on fan, the base of the clamp is flat, effectively serving as a stable stand for those who’d like to position it on a counter or desk. Campers and beach-goers have expressed satisfaction in its versatility, though a few people seem to have a minor issue with the brightness of its integrated light when it’s being used in sleep settings.

The Elechomes model can be utilized in a variety of manners as well, since it features a handheld, foldable stem and a removable base. In addition to its flexibility, it provides solid battery life and three speed settings, making it one of the most functional options available.

We decided to increase the position of the Opolar Natural, noting handy features like an automatic shutoff timer and easy-to-remove housing (which is helpful for cleaning purposes). Opted to remove the Opolar Clamp once we noted numerous instances in which the battery was unable to hold a charge after only a couple of months.

How A Fan Keeps You Cool

This is true even if you can't tell that you're sweating, as even tiny amounts of perspiration, combined with a nice little airflow, can help lower your body temperature.

Keeping cool throughout the summer months can be a daunting task. If you're not careful, however, and you let the heat get to you, you can find yourself facing a whole host of difficulties. Heat stroke is no joke, but even a little too much warmth can result in mild dehydration that can cause fatigue, headaches, and irritability at the least. Excessive heat is also likely to drain your productivity, so if you wind up overheating at work, you might find it more difficult to get your tasks done on time.

Many people will turn to air conditioners as a means of keeping cool when it gets too hot. At home, this can cause a bit of a problem for your electrical bills, and the installation of window units or the maintenance of a central unit can be a pain in the neck. In the office, while you don't have to worry about installation or maintenance, you also don't have much control over the temperature setting, and many office managers are liable to keep their spaces a little warmer to save on electrical cost.

For all of these reasons, it's a good idea to invest in a USB powered fan that can help circulate the air in your immediate vicinity. And while these fans may look a little on the small side, you may be surprised by how effective they are. Just how is it that a small fan like these and actually cool you down? Well, it turns out that has more to do with human biology then with anything special these fan manufacturers are doing.

When your body gets hot, it sweats. It may not be the most attractive reaction to the heat, but that mechanism is one of the only things keeping you from overheating. That's because all of those tiny droplets of sweat evaporate, and when they do so slightly cooler air graces your skin, creating a cooling effect.

The speed of an air current over a body of water, even if that body is a single drop of sweat, has a direct effect on its rate of evaporation. As a result, when even a small USB powered fan blows a current of air across your skin, it amplifies the evaporative effect, cooling you down more efficiently. This is true even if you can't tell that you're sweating, as even tiny amounts of perspiration, combined with a nice little airflow, can help lower your body temperature.

Which USB Fan Is Right For You?

When it comes time for you to choose a USB powered fan, you'll notice that most of the options out there are relatively small. As discussed above, the diminutive size of these fans doesn't do a lot to hinder their effectiveness, so you can set aside the feeling that you need the biggest USB fan out there, and focus on other features instead.

For such a person, the smallest possible fan is likely the best choice.

For fans like these, portability is a central question. Just how portable you need your fan to be will determine both the size and mounting mechanism you end up with. For example, if you only need a fan that will live on your desk most of the time, but that you want to be able to reposition as needed, something on the larger side with a sturdy base would be ideal. This wouldn't be the perfect fan for someone who wants to take their unit with them when they leave at the end of the day, however. For such a person, the smallest possible fan is likely the best choice. This consumer also probably doesn't need something with as sturdy a base, and may find that a fan with its own clip system would serve them better, allowing them to fasten the unit to the edge of a desk or even their computer screen.

It's also worth investigating whether the fan you got your eye on has adjustable speeds. Some fans simply turn on and off, while others give you variable speed settings, allowing you to turn them up or down as needed. It might be nice to have a fan you can turn down to a lower setting when working with papers that you don't want to blow away, for example, and then turn back up at the hottest point of the afternoon to help you cool down.

Other Tricks And Tools To Beat The Heat

Whether at home, the gym, or the office, it's imperative that you do your best to keep cool. A good USB powered fan is just one tool in a larger toolbox that you should be using on a regular basis. The following are a few additional tricks and investments that can make sure you are as comfortable as possible no matter the season.

To that end, it would be wise to keep a water bottle handy at all times.

Quite possibly the most important thing you can do when it's hot out is to stay hydrated. To that end, it would be wise to keep a water bottle handy at all times. We're not talking about a plastic bottle of water you get from a vending machine either; we're talking about a reusable bottle that you can fill up at home with clean, filtered water to keep you from dehydrating.

If you are looking for ways to keep your temperature under control without firing up your air conditioner, you may be interested in an evaporative cooler. As we mentioned above, the evaporation of water has a direct effect on temperature, and an evaporative cooler introduces a small amount of water vapor to the current of a powerful fan. The result is a stream of slightly cooler air then you would experience with a fan alone. These units are particularly effective when you can create a cross breeze in a small room.

Finally, if you want to add yet another layer of evaporative cooling to your heat-beating strategy, you should seriously consider a cooling towel. These devices are designed to hold onto a fair amount of water and drape across your neck or other body part without necessarily making you feel wet. As the water they contain evaporates, you experience an undeniable cooling sensation.
