High Capacity Battery for Extended Use - Equipped with a powerful 8000mAh rechargeable battery, this portable electric air pump provides long-lasting power for multiple inflations on a single charge. Ideal for kayaking trips, outdoor adventures, or car tire inflation, enabling inflation without a power source. Advanced Digital Monitoring System - The built-in LCD display shows real-time pressure readings. You can set and track exact inflation levels up to 25 psi (137 kPa). This accuracy helps prevent guesswork and reduces the risk of over-inflation for kayaks, inflatable boats, or car tires. Inflation with Auto Shutoff - Delivers an airflow of 100 L/min, allowing inflations to be completed in minutes. The intelligent auto-shutoff stops inflation once your preset pressure is reached, providing hands-free operation and protecting your inflatable gear from excessive pressure. Versatile Multi-Nozzle Design - Includes 6 different air nozzles and an 80 cm hose, making it compatible with a wide range of valve types found on kayaks, inflatable boats, rafts, air mattresses, and car tires. The comprehensive nozzle set covers virtually any inflation need during outdoor activities. Use scenarios - Kayaking trips or inflatable boat outings: quickly and reliably inflate kayaks, rafts, or other inflatables without external power. - Camping or outdoor trips: inflate air mattresses and other gear away from power outlets, with a portable power source. - On the road or away from a power source: inflate car tires or manage inflatables when no external power is available.
