Automatic Electric Ball Pump: Features smart pressure detection and an automatic stop function. It's incredibly convenient to use – simply preset the desired pressure and press the start button; the pump will automatically inflate the ball and stop once the target pressure is reached, saving you time and effort. Accurate Pressure Detection: Use the LCD screen and digital gauge to precisely set the inflation pressure (PSI). This feature simplifies the inflation process, allowing you to focus on the game and enjoy playing. Faster and More Powerful: Equipped with an upgraded motor, this pump delivers an airflow of up to 4 liters per minute, fully inflating a ball in just 1–2 minutes. It frees your hands and eliminates the strenuous manual pumping required by traditional pumps. Compact and Portable Design: Measuring 16 x 3.5 cm, it easily fits into a bag or even a pocket. The included storage bag makes it easy to carry and use anywhere, so you never have to worry about a deflated ball. It also features a built-in LED light and a backlit LCD screen for easy use at night or in low light conditions.
