- Powerful inflation and deflation: this air mattress pump delivers 4000 Pa air pressure and 400 L/min wind speed, allowing a single air mattress to reach 100% inflation in about 3 minutes. The 2-in-1 design supports both inflating and deflating by sucking air out. It also includes an air-blow function for outdoor camping that can assist starting a fire when needed. - 5200 mAh rechargeable battery: equipped with a high-capacity battery, it can run for approximately 60 minutes on a full charge. Use anywhere you like. The Type-C charging port enables fast and flexible charging. - Convenient Type-C charging: designed for easy use without a bulky AC power supply. Charge directly via Type-C with a power bank, laptop, car charger, or wall adapter for true portability. - 3 different nozzles: includes small, middle, and large nozzles to fit a wide range of inflatables. Small is ideal for inflatable toys; middle suits air mattresses and inflatable furniture; large fits pools, boats, and floats. Made from durable ABS material, the nozzles are strong and ready to use without purchasing extra parts. - One-button operation and high efficiency inflate/deflate: simple steps 1) select the appropriate nozzle and attach it to the inflation/deflation port, 2) hold the switch for 2 seconds to turn the pump on, and a short press to turn it off. Ensure there is no gap between the attachment’s bottom ring and the pump edge.
