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

Portable 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 expelled cool 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 utilize a high-precision cutting process, delivering a strong airflow, scientifically optimized airflow, and long-lasting, headache-free cooling. Ultra HD Digital Display & 199 Speeds: The fan features an HD digital display that shows the current air speed and remaining power. This compact fan is equipped with a roller speed control that adjusts the wind speed from 1 to 199 speeds without poles. Portable & Desk Fan: It can be used as a handheld fan outdoors and folded at a 90° angle as a desk fan indoors.
