Top 10 Best USB Fans under 20$

Can’t get your room air conditioner to fight all that heat outside? Sometimes, in large building or houses, an air conditioning might not be enough to save you from the heat, in situations like these, USB fans comes to rescue. They are compact and don’t make a loud noise like those bulky and plugged wired fans.

USB fans are a portable version of traditional fans that are lightweight and compact and can easily fit in small bags to carry around easily. They make little to no noise to let you keep your focus on your work without getting distracted. Since they are USB fans, they do not need an electric socket to use. They can use computer USB ports, wall outlets using power USB adapters, or any other place you can plug a USB into.

USB fans are ideal for close-range cooling and can’t cool an entire room, you can put it in from of you and rather than being small in size, they are powerful enough to cool you up.

Being highly portable, they can be carried around easily and can be used in places where electric outlets are not available. Due to these features of USB fans, they are in high demand and I did extensive research to find out some of the best USB fans available under the 20$ price range.

Factors to Consider Buying USB Fans

There is a huge number of USB fans available in the market and you can easily get lost in the never-ending list of products self claiming to be the best ones. In summers, we can’t always have our air conditioners with us, and sometimes even with them we might need an additional cooling source and due to this demand for these portable fans, there is a huge number of sellers in the market.

To filter your needs and preference, you need to specify few things that you should be looking at in your fan before buying any of them, and I am going to share these important buying factors with you so you can be sure to look for these features in your next USB fan.

1. Cooling Power

The primary purpose of a USB fan is to prove a cool refreshing breeze and help us get to stand in the high temperature of hot summer days. If your fan can’t provide powerful cooling then no matter how well made and premium looking it is, it will be a total waste.

  • Look for USB fans that offer multiple speed modes since you might not always need the same speed. On an average day, you might prefer your fan to be slow while on hot and humid days, you would want it to work on full power and highest speed.
  • High quality and well-designed blades will utilize the full potential of the fan and will give huge airflow for the user as nicely designed blades are made to catch and release maximum air possible.

2. Portability

Using a USB fan rather than traditional is often because of the portability feature of the smaller and compact USB fans, as they can be fit very well in a small bag and traveled around with providing you airflow in places like trains and bushes which on their own have a poor cooling system. So you want your fan to be portable enough for you to carry it easily to places like these.

  • Being compact and lightweight in size is the core of being a portable product, the lighter and smaller your fan is without compromising on power, the better you can travel with it in your bag packs.
  • It should contain a rechargeable battery of its own that can last at least 2.5 hours so you don’t always need to search for a USB port every time
  • you want some cooling for yourself.

3. Design

A well-thought-out design can make or break a product and a USB fan is no different, with the correct blade design to adjust for multi-direction airflow, your fan should be designed in a way to provide you comfort. A good design will also ensure to reduce and absorb most of the fan’s noise to provide you with a noise-free environment.

  • It should be durable and made with solid materials that can long last and can be cleaned and maintained easily.
  • It should be silent in working, as such that when in use even when on high power it should generate minimal to no noise at all and be silent while operating.
  • Can be placed in different environments well, such as a clip-based design can be hanged in places where desk fans can’t and the same goes for tripod-based designs. These make sure that you can place your fan in the most comfortable places possible.

4. Features

Some great set of features to enhance your experience is what we always look for in a USB fan. It should contain a basic adjustment mechanism and must have a solid stand method that can be used to place it in different places. A good and comfortable on/off button is also a necessity.

  • The adjustment angle of the head should be flexible enough for it to move in different directions and make the airflow in multiple ways to ensure proper cooling in all the needed directions. It should also rotate properly without any force and with ease.
  • It must have widely known and well-established position types such as clip-based or a stand-based position that allows the fan to be placed in a place without any movement.


Are USB fans worth it? 

Yes, a powerful USB fan is more than necessary with current weather scenarios. They are convenient and provide the best compact cooling option available and increase the airflow and even support your air conditioning to cool better. Being compact and lightweight they are portable also and can be carried around easily.

Can a USB fan be plugged into a phone charger?

Yes, a USB fan only needs a USB port with a power supply in it and a phone charger will work like a charm. You can even use your computer or laptop to charge or use these fans too. This makes it highly convenient to plug in any device available and use.

What is the normal RPM of a USB fan? 

USB fans RPM comes in a variety of ranges and can differ greatly due to the type of USB fan you are using. Still, the most common average is 2000 RPM which is good enough to get you cool and fresh.
