The fan blades are made of a flexible plastic film, so does the fan use energy?

Does the USB fan consume power?

USB fans are generally smaller in size and the space they can blow into is limited. We can therefore imagine that the power consumption of USB will not be very high. The standard voltage of the USB fan interface is 5V. The maximum output is said to be only 500mA, so the rated power is basically less than 10W. In this way, 1 kilowatt hour is equivalent to 1000 watts , and it takes at least 100 hours to consume 1 kilowatt hour of electricity, so the power consumption is very low!

Advantages of USB fans

1. Easy to carry, plug and play, usually small in size, easy to carry, and can be plugged into a laptop or mobile phone. Let you feel the cool breeze. Good security and low noise. The blades of the USB fan are made of plastic filmic flexible. Although the rotation speed is fast, it is absolutely safe, has low noise and good wind resistance. You feel like a lucky little fan when you blow it.

2. Different personalized, fashionable and exquisite USB fans give you more choices. Not only is it functional, but it also adds a lot of color to your desk.

Therefore, users need to adjust according to the type of USB electric fan they purchase.

2. When usinga USB fan, it should be noted that its operating power is closely related to the output power of the computer. If you find that the USB fan does not work during use, you should immediately unplug the USB cable from the USB fan to avoid burning the computer.

The respective characteristics of USB fans:

1. The portable USB fan can be powered by batteries and can be folded. Can be recharged.

3. Universal USB fan, with relatively simple appearance and simple functions. There is only an on/off switch and the fan speed cannot be adjusted. The biggest advantage is large air volume and low noise. The market price ist from 20 to 30 yuan. Unable to load.

4. USB fan with adjustable speed. The power switch adopts button type. The biggest feature is of course that the air volume can be adjusted. The fan blades are made of urethane, which is soft, has low air volume and low noise. The base part of the motor is connected by a pipe, and the blowing angle can be adjusted. The market price is 25-35 yuan. Unable to load.

5. Giant USB fan, larger than other ordinary USB fans. It also provides negative ion generation function. In addition to fresh air, it can also generate negative ions during work, creating a conducive environment for users to use the computer.environment.

6. Creative USB fan with great personality. Better air structure allows for a more complete air supply. At the same time, thanks toCreative design elements, small fans become more attractive.
