1.180 and adjust the air supply automatically up and down 90, which can not only automatically shake your head about 180 and supply air in a large area, but also manually adjust the air supply angle up and down 90, making the distance and height refreshing. 2. Strong endurance, continuous air supply hours, built-in 2000mAh rechargeable battery, and only 7W energy-saving design, the endurance time of the first wind speed is as long as 5 hours, the second gear is 3.5 hours, and the third gear is 2 hours; Using brushless copper-core motor, running softly and slowly can not only reduce the sound when running, but also reduce the power consumption, which is more energy-saving and electricity-saving. 3. One-key switching of three-speed wind speed, simple design and simple life; The first gear: the refreshing experience of the breeze; The second gear: refreshing and double sweeping away the sultry; Third gear: strong wind speed and instant coolness. 4. Newly upgraded 7 turbine blades are strong and soft, and 7 inclined and rotating blades are more powerful; Innovative aerodynamic design, aerodynamic design can be reduced with external environmental factors; Air resistance, compared with similar competing products, the wind speed increased by more than 20%, and the work efficiency jumped by 30%. 5. Easy-to-remove masks are easier to clean, and fans will naturally cause dust accumulation for a long time, which will affect health. We design easy-to-remove masks to clean the fan blades more easily.
