-Fast Ball Pump: The electric ball pump reaches a pressure of 12 PSI (82,000 Pa), has an airflow of 4 l/min, inflates powerfully and fills a ball in just 1-2 minutes. The perfect choice for saving time during the game. -Rechargeable Ball Pump: Built-in 2000 mAh lithium battery, allowing 30 balls to be inflated on a full charge. Comes with a micro-USB cable, which can be charged via a mobile phone adapter, computer, car's USB port or power bank. -LED Display and Flashlight: The ball pump's large LED display shows the preset pressure, real-time pressure and battery life, and there is a flashlight at the bottom for use at night. This ensures extra user-friendliness. -2 Needles and 1 Nozzle: The mini ball pump comes with 2 needles and 1 nozzle, allowing you to inflate most sports balls: football, rugby, volleyball, basketball, handball and other inflatable balls, as well as swimming rings, etc. -User-friendly: Set the exact PSI (pressure unit) for the basketball, and the pump will automatically stop when the preset pressure is reached. You don't have to worry about the ball's pressure being too high or too low. The mini handball pump is lightweight and saves space in your pocket. Instructions for use: Accessory installation: There are two ways to use the pump. 1. Connect one end of the air hose to the needle and the other end to the pump's air outlet. Then insert the needle completely into the ball. 2. Screw the needle directly onto the pump's air outlet and insert the needle completely into the ball. Preset PSI: Set the desired PSI based on the ball type. Turn on the switch to start inflating. 1. After installing the accessories, it is advisable to test each connection point to ensure it is correctly installed and to check for leaks. If a leak is found, it must be adjusted to ensure that the air pump gets a more accurate pressure, which improves the inflation experience. 2. Since the product's pressure sensor may have an error of 1 psi, it is advisable to add 1 psi to the expected value when setting the psi value for better results. 3. For first use, you can test the most suitable psi several times. The air pump has a memory function and saves the used psi next time you turn it on. 4. Avoid accidentally touching the switch during use, which causes the air pump to stop working before the ball is filled. 5. If the displayed pressure during use deviates from the actual pressure, press the \"+\" and \"-\" buttons simultaneously to reset the calibration without connecting the inflatable object.
