it roughly takes 1500~ Manual pumps to fill a 4500 psi Bottle and from what i can see, each cycle on this machine is around 3~ Seconds. so 3 x 1500 = 4500 Then devide that by 60 to get the time 4500 / 60 = 75 Minutes
Not a good solution! O-rings wear out quickly, the pump overheats! To charge 1 pcp air gun, it takes 3-4 rest times for the pump to cool down! Otherwise, the o-rings will break down very quickly!
