4 Preset Modes: The MY01 electric ball pump is an upgraded version that has been designed with 4 preset ball modes: basketball, soccer, football and volleyball. You don’t have to preset the pressure anymore; Just one-key select the ball mode you need and inflate that is more convenient to use. Also, we do reserve the custom mode that you can preset manually to inflate other balls. (NOTE: it is not suitable for balls requiring pressure under 2 PSI )

New Function--Deflation & More Accurate Pressure Detection: This air pump for ball detects pressure more accurately than the old version. Not only can it inflate the sport balls, but also it has deflating function that can help deflate to proper pressure if the ball pressure was too high. (Press and hold the "-" button to deflating)

Twice Faster & More Powerful：Equipped with upgraded motor, the MY01 inflates twice faster than the old version that will fully inflates a ball within one minute. Additionally, it can inflates higher pressure up to 15 PSI, while the old version is only 12, which is more powerful that can work for other balls with higher pressure requirement.

Automatic Ball Pump: This is an automatic ball pump, which is different from the push-pull air pumps that are inefficient and exhausting. It inflates and stop automatically. Ultra easy to use, even for children. Also, it brings great help for coaches, whom have to inflate tons of equipment before the practice session, to save their time and energy.

Portable: This ball pump has a compact design (Size: 6.29*1.57*1.57inch, Weight: 0.55LB) which is portable. It fits in your bag and even your pocket, easy to be carried to the court and other where you might need it. Also, the MY01 version has been built in a needle storage hole that you can store a ball needle inside. What a convenient design!
