Compared with ordinary AC fans, what are the advantages of DC stand fan?

Compared with ordinary AC fans, the DC stand fan (DC stand fan) of DC floor fans have significant advantages in energy efficiency, performance and user experience. DC stand fan are more efficient, usually with a power of only 30%~50% of AC motors (such as 35W DC stand fan vs. 50~80W AC motors), which can significantly save electricity bills in the long term. DC stand fan reduce energy loss through electronic commutation (brushless design), while AC motors lose some power due to electromagnetic induction and carbon brush friction.

DC stand fan do not require carbon brushes, which avoids mechanical friction noise. The noise during operation can be as low as 20~40 decibels (close to the sound of natural wind), which is suitable for use in bedrooms or at night. DC stand fan have uniform torque and precise speed control, which reduces fan shaking and resonance noise.

DC fans usually support 6~8 gears or more (AC fans generally only have 3 gears), and users can accurately select a comfortable wind speed. Some high-end DC fans support stepless speed change, and the wind force adjustment is smoother.

For example, this product is equipped with a 4400mAh battery, which can run for 7.5 hours when fully charged (AC fans must be plugged in and cannot be disconnected from the power supply).

DC stand fan are easy to integrate with smart modules, supporting remote control, touch screen, APP control, and even voice linkage (such as access to smart homes). You can set a 7.5-hour timer to shut down, and some models can also remember the last use preferences (such as gear position, head shaking angle).

DC stand fan have no carbon brush wear, and the theoretical life can reach more than 20,000 hours (AC motors are about 10,000 hours). There is no need to replace carbon brushes or lubricate frequently.

DC stand fan are highly efficient, generate less heat, and reduce the risk of overheating. High-quality DC stand fan use a shielded design to avoid interference with Wi-Fi, Bluetooth and other signals.
