Can you manually inflate air mattress with built-in pump?
Spread the mattress on a clean floor. Open the valve and put the pump hose inside the mattress. Start pumping the air inside the mattress and make sure no air gets out. And quickly close the valve after inflating the mattress.
What does built-in pump mean for air mattress?
A built-in pump is an internal pump that is built inside the air mattress and can be either battery-operated or electrically powered. Either way, you won’t have to struggle with fitting any external equipment into the valve, and you won’t end up with sore leg muscles from manually pumping up the air mattress.
