Although many people know about DC fans, they may not know how to use them and how to use them safely. For example, how is a DC fan used? Can it be plugged directly into the DC power supply? Or can it be used after charging? Is the electricity used for charging DC or AC? How long can it be used after charging? What is the price difference between a DC fan and an ordinary AC fan in the same size? The following is the answer from the DC fan manufacturer.
First of all, the DC fan must be driven by a DC power supply! The voltage of the DC power supply used must be consistent with the working voltage marked on the fan. The battery is a DC power supply. If it is used to drive a DC fan, in addition to charging, it also depends on whether the voltage of the battery is consistent with the working voltage of the fan. If it is inconsistent, a DC/DC converter should be used to make the voltage consistent.
The prices are similar. The DC fans are generally used in cars or in places where it is inconvenient to use mains power. Of course, the cost of using AC is more economical, and there are many varieties of AC for you to choose from. As for the power supply and voltage All have to correspond to charging and use it. Generally, do not turn it on during the charging process. After charging, use it again (4~8 hours). If there is a plug, use AC power. I have never seen one without a plug. The use time after charging is basically the same as the above, and the prices of AC fans and DC fans are not much different. But remember: Except for the safety manual and charging voltage, what power and service life are basically imaginary.
