Precise Pressure Monitoring Equipped with a digital display screen, it allows you to monitor the pressure in real-time. With accurate readings and the ability to switch between PSI, BAR, KPA, and KG/CM2 units, you can easily determine the optimal inflation level for different inflatables. Intelligent Preset Modes The pump offers four convenient preset modes - tent mode, surfboard mode, swim rings mode, and custom mode. Simply choose the desired mode, and the pump automatically stops inflating when the preset pressure is reached, preventing over-inflation and ensuring safety. Versatile Power Options The built-in 8000mAh large-capacity battery provides long-lasting operation and eliminates the hassle of tangled cords, offering you ultimate portability. Additionally, the pump supports car power supply, making it a perfect companion for outdoor adventures without worrying about running out of power. High Efficiency and Time-Saving The portable inflatable pump, designed for convenience, ensures a high inflation rate of 100L/min and a maximum pressure of 25PSI. You can rely on its swift performance to quickly inflate various items such as paddleboards, kayaks, inflatable boats, air mattresses, and more. Use scenarios - At the lake or beach, quickly inflate a paddleboard to your preferred PSI for stable handling. - On camping trips or family gatherings, use preset modes to inflate air mattresses and pool inflatables without guesswork. - During road trips or outdoor events, connect to a car power supply to power the pump when charging stations are unavailable.
