Portable fan, mini rechargeable fan 5000 mAh, small quiet turbo fan with adjustable speed (1 to 199), cooling fan for camping, sports, travel (black)

Mobile Air Conditioner: The new cooling fan uses semiconductor cooling technology to cool down to -10°C in 3 seconds, increasing wind power by 90% and reducing the feeling of icy cold by 88%.

Brushless Motor: The mini fan is equipped with a brushless motor, which significantly improves wind speed and power.

The maximum air speed is 10 m/s and the maximum speed is 15,000 rpm (200% higher than a normal fan). Turbo Fan: This portable fan uses aircraft-grade turbo blades to simulate the power of an aircraft engine, rapidly compressing and cooling the inhaled hot air into fresh expelled air, for rapid, hurricane-like cooling. Air Jet: Specially designed wind guidance structure for precise blowing to the target area, reducing airflow loss and improving usage efficiency. The fan blades use a high-precision cutting process, providing a strong airflow, scientifically controlled airflow, and long-lasting cooling without headaches. Ultra HD Digital Display & 199 Speeds: The fan is equipped with an HD digital display that shows the current air speed and remaining power. This small fan is equipped with a roller speed control that regulates the wind speed from 1 to 199 speeds without poles.
