- First, the most important
- A USB fan won't make hair fly rock'n'roll, due to its size and power. Less power also leads to less energy consumption, a consumption that turns around 25 times less than a common fan.
- The word “USB” means that these fans are for use in this type of socket, present in notebooks and desktop computers (cell phone adapters also work).
- If you don't like the noises caused by air circulators or conditioners, these little ones are good options. USB fan motors are quite quiet compared to any other air circulating products.
- Its size and weight make it very versatile, with use in virtually every situation. The portability allows many to be turned in any direction (360°), which is very practical.
The best USB fans on the market: Our favorites
Among the advantages of a USB fan, we can highlight its size. Compact, it takes up little space on your desk and cools all around you. An inexpensive option to end the heat once and for all. Below, check our ranking with the best models on the market.
Micro USB Ventisol Fan
A safe-looking, portable device with a metal grill to protect the propellers from accidental shock. Medium length USB cable included for power connection.
It has a design similar to some air circulators, with an approximate size of 15 cm high by 15 cm wide, and a propeller diameter of 9.5 cm. The equipment is made of metal and plastic, with ABS propellers.
It has a fixed base (needs a flat surface to stand on), with an energy consumption of 0.003 kw/h (up to 30 times less than a standard fan), and a power of 3 W, allowing 150 RPM (the propellers rotate 150 times per minute).
Powerful Mini USB Fan
Like every USB fan, it's portable, with a plastic housing and grilles protecting the propellers from accidental shocks. Short length USB cable included for power connection.
The differential of this model is that it has an internal lithium battery that allows the use of the product without the need for a cable, having autonomy for approximately 40 minutes.
Compact in size, it is approximately 15 cm high by 12 cm wide, with the possibility of choosing colors. It also has a button for speed selection (three levels), in addition to a flashlight function, made by a led lamp.
Western Mini USB Fan
Portable equipment with a more minimalist or “root” characteristic, with a flexible rod that has a USB connector cable at one end and the motor with a propeller at the other.
Due to this feature, it does not have the propeller protected against accidental touches and does not have a cable, being a proximity fan.
The product also has a drop of LED for lighting (reading, computer keys) and that, due to the flexibility of the rod, allows different positions of the same.
The fan can be found in different colors, with a rod length of approximately 20 cm (from the USB cable to the motor), with about 10 cm in diameter between the blades.
buying guide
Not everyone likes working in an air-conditioned environment. And an alternative to cool off is the USB fan, which in addition to consuming little energy, fulfills its main function very well.
They are small, silent and give a charm to the environment. Want to know more about this product? Stay with us to learn everything you need before making your purchase.
What is the USB fan and what are its advantages?
USB fans are small air circulators with the same characteristics as the original, to run from computers, creating a continuous gust of wind for their direct users.
Extremely light and inexpensive, they are small (on average half the size of a class ruler) and don't need plugs to work.
Their main characteristic is their portability and mobility, where any small space can be used by them.
Whether fixed base or flexible rod, most products are capable of movement up to 360° (a full circle), but not automatically, you need to steer.
They also do not have a remote control, as the distance from the product to its user is always very small.
The working principle is the same as a normal fan. There are the blades, which rotate at great speed and “hurl” the air at a speed in the direction they point, at a temperature lower than that of the environment.
Of course, when investigating more about the product, you will notice that there is also a decorative issue involved, where there are fans able to draw attention by the delicacy of the shapes in their reduced size, and even by the shapes and models of some of them.
How about a little comparison between the little ones and the big ones?
USB fans Standard fans
silent engine Motors with high noise
Battery for use without power source Useful for entire environments
Compact and portable Risk of tripping in wiring and apparatus
Energy consumption up to 30 times less
Different designs and formats, also for aesthetic purposes
Refresh only close people
Of course, we are talking about mobility here, and for this reason the USB fan is a great choice! If the topic is “cooling an entire room”, then it is unfortunately not what you are looking for.
But, in a workplace, nobody wants to risk a flight of papers when the wind hits where they are, right? So, cheers for the USB fan!
What to pay attention to: fixed base or flexible rod?
We're talking about fans with everything smaller. Smaller size, lower power, lower consumption. So don't be fooled into imagining that this product will bring wind to everyone on the living room sofa.
It brings a directed air, capable of reaching up to two meters of distance, with the particularity of connection via USB ports – use in computers or even adapters for sockets.
If you often use a workstation, any model with a fixed base can be an option, as it will surely conquer its little place next to the screen, sending that gentle breeze for you.
Now, if your workstation does not have a fixed base, you should invest in purchasing a product with a flexible rod (the USB socket is part of the product) or even a device with battery.
This will allow you mobility in placing it where possible without necessarily needing the cable connected to the computer.
As we believe in tables (and them in us), we prepared a list of possibilities, and beside a suggestion of USB fans with better adaptation to the case.
Possibilities Product suggestion
Fixed workstation Fixed base fan with USB cable
work anywhere USB fan with rod, USB fan with internal battery
Working in low light environments USB fan with flashlight function
Notebook with low battery life USB fan with internal battery
Work in tight places USB fan with rod
To avoid dissatisfaction, first try to identify your need and then what features the product must have to satisfy them.
Following this path, you will certainly choose the best model, even among so many.
How much?
Now let's go to the cost-benefit ratio, which is very attractive when we come across these accessories.
You already know what this product offers, and as for the price, a USB fan can easily be found from R$20 to R$50.
Other options (with ice drawer, for example) are found for a higher value, but this variation is mainly based on what the equipment intends to do.
Where to buy?
USB fans are products that have been on the market for some time, and are very accessible to the consumer, especially in department stores such as: Americanas, Casas Bahia, Leroy Merlin.
But, if you are interested in researching and choosing from a greater variety, the recommendation is without a doubt to buy online, where you can choose and receive in the comfort of your home, in stores like Amazon.
Purchasing Criteria: Factors to Compare USB Fan Models
A USB fan is a relatively simple electronic device with very specific functionality. Therefore, what you need to take into account when purchasing are the following points:
- portability
- Autonomy
- Propeller size
- power
- design
Below, we will detail each one of them so that you can make the best choice when buying a USB fan.
portability
That's basically where the equipment will go. It's no use searching for fixed-base USB fans if you don't have space or place to keep it working.
Keep in mind that USB power means a cable connected to the computer (or a power source through an adapter) and the fan.
Think carefully about how you intend to use the product and in what situations this will occur, so that you have the best options when considering buying.
In the Purchasing Guide section above, we detail the differences between fixed-base and flexible-stem fans, be sure to check it out.
Autonomy
Being powered via USB, it will help to drain your computer's power. If it's plugged in, that's fine. But what if it's the notebook battery?
So, if your computer is running low on battery power, almost dependent on the outlet, opt for models with an internal battery that can be charged earlier.
Propeller size
When we talk about a fan, size can be a document. The width of the propellers will give you partial information on how much air will be directed, increasing the contact area.
This information is worth a lot when we are talking about warmer places, or the need for the wind to reach as much of your body as possible. The larger the blades, the greater the chance of this happening.
Check these dimensions in the description of each product.
power
USB fans will not have a great potential for causing wind, but they are capable of cooling.
The greater their power (usually transmitted in watts -W), the greater their ability to rotate the propellers in a unit that is called revolutions per minute, or RPM.
The higher this number, the greater the chances of a good wind load. So look for more powerful fans, with more revolutions per minute.
design
We've already said that in addition to being functional, they can make the environment even more stylish. With this factor in mind, analyze the style of the place where you work - or any other environment where you want to use the product.
Are you the basic black type or do you like gadgets that make the place more stripped and colorful?
There are varied options on the market and in this guide we have very different models, which you can check in the ranking.
That way, you can choose the one that is more like you or your business, be it cool or more traditional.
