【Maximum 120m/s Wind Speed & 3-Stage Adjustment】We have honed advanced power electronics technology for many years and incorporated our independently developed brushless DC motor technology into our products. This has increased the maximum rotation speed to 300,000 RPM, expanding the range of applications. At the same time, we have retained the original wind speed adjustment function, allowing you to adjust the airflow to your preferred strength in 3 stages to suit the usage scenario. High Speed: (300,000 RPM) Can be used to blow away or gather debris, dust, and fallen leaves generated at construction sites or during pruning work, and can also be used to blow away water droplets when washing a car. Medium Speed: (250,000 RPM) Sand and water in small gaps often remain even after sweeping with a broom, but a blower can blow them away in an instant. Cleaning of parking lot asphalt cracks, entrance tiles, window sashes, etc., can also be done efficiently. Low Speed: (200,000 RPM) Useful for blowing away wood and metal shavings. 【100% Brass Ultra-Powerful Brushless Motor】Adopting an upgraded ultra-powerful motor, it can blow away dust from every corner of computers and other devices. It can be used easily anywhere without choosing a location. 【10000mAh Large Capacity Battery & Fast Charging】Built-in 10000mAh large-capacity lithium battery, it can be used for up to 150 minutes with a full charge of about 2-3 hours, supporting the smooth completion of various tasks. In addition, the USB-C charging port supports fast charging, enabling fast and efficient charging. 【Equipped with Two High-Brightness LED Lights】Adopting the latest LED high-intensity light chips, the lifespan of the lights reaches 10,000 hours. Bright and uniform light. Lights are installed on both ends with different functions, and can be operated separately, allowing you to see clearly and clean even at night or in dark places such as corners. s59
