• 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 sensation of icy coldness by 88%. Brushless Motor: This 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 regular fan). Turbo Fan: This portable fan uses aircraft-grade turbine blades to simulate the power of an aircraft engine, rapidly compressing and cooling the inhaled hot air into expelled cool air for hurricane-like rapid cooling. Air Jet: Specially designed wind guide structure for precise blowing to the target area, reducing airflow loss and improving usage efficiency. The fan blades use a high-precision cutting process. Strong wind. Scientific airflow design. Long-lasting blowing without headache. Ultra HD Digital Display & 199 Speeds: The fan is equipped with an HD digital display showing current air speed and remaining power. This small fan has a roller adjustment ratio that regulates wind speed from 1 to 199 speeds without poles. Portable Fan & Desk Fan: It can be used as a portable handheld fan outdoors and folded 90° as a desk fan indoors.
