The Key Point Of Choosing A Handheld Fan
Oct 11, 2021
1. Wind speed size
Although the wind speed of the USB fan is not comparable to that of the general cooling fan, the weaker wind speed is not good. This immediately determines whether the USB fan is blown cool enough.
2. Application convenience
The original intention of the USB fan design is to make the application more convenient. If it is large, heavy, and inconvenient in actual operation, it will increase the pressure.
3. Endurance
The longer the use time, the stronger the applicability. According to the battery power size, the length of the battery life can be understood, and it is best to choose a battery above 2000mAh.
4. Noise reduction
This is very important. Of course, the lower the noise, the better. A noisy USB fan will affect work and rest. If it is used in an office or classroom, it is very easy to harm others.
