Specifications

8-inch USB Desktop Fan

Key Performance Characteristics:

Airflow and Performance: The 8-inch fan blade design typically delivers stronger airflow compared to 6-inch or smaller fans. Thanks to the optimized brushless motor, the airflow distance is moderate, making it suitable for close-range, high-intensity cooling.

Noise and Energy Consumption: High-quality products use a DC brushless motor, resulting in low noise during mid-range operation (around 42dB for some models) and low energy consumption, making them both quiet and energy-efficient.

Power Supply and Battery Life: Supports universal USB power supply (connects to computers and power banks), enhancing portability. Some models have built-in lithium batteries (e.g., 2200mAh to 10000mAh) for continuous use during mobile or power outage scenarios.

Design and Structure: Supports multi-angle airflow (e.g., 90 degrees) for convenient air circulation. Most adopt a compact design, with a tabletop/clamp-on structure for efficient space utilization.

Specific Applicable Specifications and Features:

Size and Scenarios: The 8-inch (approximately 20cm in diameter) fan is moderately sized, suitable for small spaces such as desks, study desks, and bedside tables, without obstructing the view.

Power Specifications: Standard 5V USB interface, supports power supply from computers, power banks, and USB sockets; some models support built-in battery charging.

Function Specifications: Typically uses a DC brushless motor, with low noise and 3 adjustable speeds (low, medium, and high).

Design and Maintenance: Mostly 3 or 5 blades, with materials mostly plastic or metal mesh covers; it is recommended to choose an odd number of blades to reduce rotational resonance.

Usage Precautions: Due to its rated power and airflow distance limitations, it is not suitable for cooling large spaces; it is more suitable for personal close-range direct airflow.
