Rechargeable cordless portable air pump that delivers fast inflation and convenient deflation for low-pressure inflatables, travel storage, and outdoor use. Key benefits and why you need it: - The built-in 5200 mAh lithium-ion battery provides extended runtime for outdoor use without frequent recharging. - High airflow of up to 400 liters per minute and a working pressure of 4 kPa accelerates inflation and deflation, cutting wait times at the beach or campsite. - One-button operation and four LED battery indicators make the pump simple to use for all ages. - Compact and lightweight at 340 g with a matching drawstring storage bag, so the pump and all accessories fit easily into a backpack, suitcase, or beach bag. - USB Type-C charging supports power banks, car adapters, laptops, and wall adapters for flexible recharging on the go. - Four interchangeable nozzle sizes cover approximately 90 percent of common inflatables and ensure a tight fit to prevent air leakage. - Separate inflate and deflate channels maintain steady airflow and protect the motor, while the internal heat dissipation structure helps prevent overheating during extended use. Performance and features: - Built-in battery capacity is 5200 mAh, which supports longer continuous operation compared to typical 2000 mAh pumps. - Maximum airflow is 400 l/min and working pressure is 4 kPa, enabling faster inflation than many lower-capacity pumps. - Typical inflation times are approximately 15 to 25 seconds for swim rings, 45 to 60 seconds for pool floats, and 55 to 65 seconds for single-person kayaks. - Dual ports allow separate inflate and deflate functions for quick venting of vacuum storage bags and large inflatables. - Four nozzle sizes are included: S for small toys and thin valves, M for medium floats and children pools, L for air mattresses and kayaks, and XL flat nozzle for vacuum compression bags. - Durable ABS housing with internal heat dissipation protects the pump during repeated use. - Simple one-button control is intuitive and suitable for all users. Compatibility and limitations: - The pump is suitable for low-pressure inflatables such as swim rings, pool floats, inflatable slides, air mattresses, camping sleeping pads, inflatable kayaks, and vacuum compression storage bags for clothing and bedding. - The pump is not suitable for high-pressure items such as sports balls requiring high pressure, vehicle tires, latex balloons, or foil balloons. What is included: - One rechargeable portable electric air pump. - Four interchangeable nozzles in sizes S, M, L, and XL. - One Type-C charging cable. - One drawstring storage bag.
