Mobile Air Conditioner: The new cooling fan uses semiconductor cooling technology to cool down to -10°C in 3s, increasing the wind power by 90% and cooling the icy feeling by 88% Brushless Motor: The mini fan is equipped with a brushless motor, which greatly improves the wind speed and power. The maximum air speed is 10m/s, and the maximum speed is 15000 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, quickly compressing and cooling the inhaled hot air into expelled cool air, for rapid hurricane-like cooling. Air Jet: Specially designed wind guide structure, for precise blowing to the target area, reducing airflow loss and improving use efficiency. The fan blades use a high-precision cutting process, strong wind, scientific cutting of airflow, long-lasting blowing without headaches. Ultra HD Digital Display & 199 Speeds: The fan features an HD digital display that shows the current air
