How Do I Know if My Fan Is AC or DC

October 30, 2024

To determine whether your fan is powered by alternating current (AC) or direct current (DC), you can check the following:

Check the label: Look for a label on the fan or its power supply. It should specify the input voltage and whether it is AC or DC. AC voltage is typically 110V or 220V, while DC voltage is usually 12V, 24V, or 48V.
Check the power cord:

If the fan has a two or three-pronged plug that can be plugged directly into a wall outlet, it is most likely an AC fan.
If the fan has a low voltage power adapter or plugs into a USB port, it is likely a DC fan.

Check the fan’s manual or specifications: If you have the fan’s manual or can find its specifications online, it should state the power requirements, including whether it uses AC or DC power.

In general, most household fans, such as ceiling fans, table fans, and floor standing fans, are powered by AC. However, some smaller, portable fans, like those used in cars or powered by batteries, use DC power.
