Electric ball pump designs with intelligent automatic inflation feature, slide "ON" switch to automatically inflate and then feel it for yourself. Because this air pump will not stop on its own, you must manually turn it off by sliding the switch to "OFF" when you believe the inflation is sufficient.
The Ultra Fast Air Pump for Balls has an ultra fast air volume (3.5 L/M, 1-2 mins finish inflate), so you will never have to delay the game with unnecessary pumping again, and there will be no need to push and pull on the handle like before, just take a break to wait 1-2 mins. Allow your hands to be free!!! NOTE: This is ONLY for people over the age of 12!
