Small Cordless Portable- Unlike other air pumps on the market that require a power source, the electric air pump can be used not only at home but also at the beach, camping, and outdoor parties. The overall size is small and exquisite, and it can be easily put into a backpack when not in use, without adding extra weight. Long-lasting Power & USB Charging- The electric battery air pump has a built-in 5200mAh rechargeable lithium battery, which provides a longer working time. The included USB charging cable can be used with any device that has a USB interface, such as a car seat, computer, or power bank, making it more convenient for your summer travels. Faster Inflation and Deflation- Inflation and deflation can be completed in just a few seconds to several minutes, depending on the size of the object, thanks to the 15W high power and 400L/min airflow. Simply insert the air nozzle into the valve and turn on the switch. Less waiting time means more time to play or relax! Safe and Drop-Proof- The portable battery air pump has an overheating protection function and can work continuously for a long time without burning out, so kids can use it with confidence. The air pump is made of durable, non-slip materials that are easy to grip and use. 3 Different Nozzles- The electric air pump comes equipped with three different nozzle types to meet your various inflation needs. It's perfect for air mattresses, inflatable swimming pools, swimming rings, children's paddling pools, yoga balls and other inflatable items.
