How to choose a good small table fan?
Things to note when purchasing a small fanAlthough small fans are very cheap products, they may only cost 1-2 meals, but if you buy the wrong one because you don’t see the details clearly and it is not so convenient to use, it will still be a big loss, so I will sort out the general points that need to be paid attention to for everyone. refer to.
Choose USB socket or normal power socket
This depends on where you use the small fan. For example, if you place it next to the bed, your socket must have a USB socket. Otherwise, you need to choose a type with wireless battery life, or just buy a type with an ordinary power socket.
Battery life
Most small fans on the market use USB interfaces and can be used wirelessly. Wireless use depends on battery life, especially if a small handheld fan is used outdoors. If the battery capacity is within 2000mAh, the highest wind speed will be very effective. It may only have about 2 hours of battery life, which is definitely not enough. Therefore, it is recommended to choose a battery with a capacity of more than 4000mAh for a small handheld fan. The maximum wind speed is basically enough for a day of outdoor use. The batteries of the small handheld fans introduced in this article are all above 4000mAh, and the battery life is relatively long.
Noise value
Generally, 50-60 decibels is equivalent to the sound of normal conversation. Generally, small fans running at low speed can be within 40dB, and running at high speed can be considered relatively low noise at around 40dB. If you want it quieter, you can use a type with more rotating fan blades. The fan blades have a softer airflow and generally produce less noise.
