【Latest Technological Breakthrough】: New high-quality brushless motor, special air duct design and excellent circuit design make the motor heat dissipation more even. This means that during use, it does not need to stop working for cooling due to the motor overheating like other air pumps. Our air pump can work continuously until the battery runs out! 【Super Mini Portable】: The electric air pump weighs about 140g and measures about 49.5*49.5*82.5mm, which is smaller than your fist. It can be easily put in a backpack or pocket. With ABS shell and good sealing technology, one-button operation, it is a must-have for outdoor camping, hiking, beach and indoor storage bags, no longer limited by power supply. 【Fast Inflation/Deflation】: The portable air pump is equipped with a powerful motor, with a maximum air pressure of 4kPa, a maximum wind speed of 200L/min and a power of 30W. It only takes about 15-20 seconds to fill a swimming ring, about 100 seconds to fill an air mattress (without a control plug), 2-3 minutes to fill an inflatable pool and 30-40 seconds to compress a vacuum storage bag (depending on the size of the product). 【Air Pressure Sensor】: The ultra-mini pump has a built-in special air pressure sensor. When the air pressure inside the inflatable product increases, the air pump will increase the speed to increase its own air pressure. This means that your inflatable product can be filled to the max, instead of being like a deflated rubber ball. 【Rechargeable and Nozzle】: Built-in 1200mAh lithium polymer rechargeable battery, fast charging with Type-C interface, charging time only 3-4 hours (with a 10W-20W adapter), can work continuously for 20 minutes-25. Equipped with 5 different nozzles, it can be adapted to most inflatable products. Note: This air pump cannot inflate tires, balloons or basketballs. Note: 1.
