As a portable cooling device, handheld fans take brushless DC motors as their core technology in production. Compared with traditional motors, energy consumption is reduced by about 40%, with a rotation speed of over 15,000 rpm, delivering strong wind while ensuring low-noise operation. The body is mostly made of ABS+PC composite plastic, balancing durability and light weight, with a single unit weight controlled within 150g for easy one-handed grip and portability. In production, precise mold injection and modular assembly enable efficient integration of fan blades, motors, batteries, and control modules. Soft rubber blades and automatic stop protection are added to enhance safety.

In application scenarios, handheld fans are highly adaptable. During commutes, they can be operated with one hand to quickly relieve stuffiness in vehicles; for outdoor camping and sports, no external power is needed, and a built-in 4000mAh battery supports 100-speed continuous operation for 3–10 hours. In offices, their low noise does not disturb work, and they can be fixed on desks with brackets. Some models integrate power bank functions to meet emergency charging needs for mobile devices, expanding their use cases. With mature production processes, handheld fans continue to optimize wind power, battery life, and portability, becoming an essential summer companion.
