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 at a higher price, but this variation is mainly based on what the equipment proposes to do.

USB fans are products with a certain time in the market, and are very accessible to consumers, mainly in department stores such as electronic computer item shop.

But, if you are interested in research and choose in greater variety, the recommendation is undoubtedly the online purchase, in which you can choose and receive in the convenience of your home, in stores like Amazon.

Purchasing criteria: Factors to compare USB fan models

A USB fan is relatively simple electronic equipment, with very specific functionality. Therefore, what you need to take into account when purchasing are the following points:

• Portability
• Autonomy
• Propellers size
• Wattage
• Design

Next, we’ll detail each one so you can make the best choice when buying a USB fan.

Portability

It is basically where the equipment will be. There is no point in researching fixed-base USB fans if you don’t have the space or place to keep it running.

Remember that USB power means a cable connected to the computer (or to a power source via an adapter) and to the fan.

Think carefully about how you intend to use the product and in what situations it will occur, to have the best options when considering buying.

Here is an example of a USB fan with a flexible rod:

In the Buying Guide section, above, we detail the differences between fixed-base and flexible-shaft fans, be sure to check.

Autonomy

Being powered via USB, it will help to drain power from the computer. If it’s plugged in, that’s fine. But what if it’s the notebook battery?

So, if your computer already has the battery in the last, almost dependent on the outlet, choose models with internal battery that can be charged before.

Propellers size

When we talk about a fan, size can be a document. The width of the propellers will give you partial information on the amount of air that will be directed, increasing the contact area.

This information is very valuable 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 occurring.

Check these dimensions in the description of each product.

Wattage

USB fans will not have a great potential to cause 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 already said that in addition to being functional, they can make the environment even more stylish. Thinking about this factor, 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 accoutrements that leave the place more stripped and colorful?

There are varied options on the market and in this guide we have brought very different models, which you can check in the ranking.

That way, you can choose the one that looks more like you or your business, whether cool or more traditional.
