This is a great mini hand pump for those simple inflation jobs such as
Beach Balls between mini 4-Inches to even larger 16-inch and larger if
you have the endurance. Smaller beach balls inflate with a half dozen or
so pumps and great when electric or larger Hand Pumps are not needed.
Pumps as fast as you can pump it. This is a manual pump that may take some getting use to as they all do.
Once you have the technique down, it's a breeze plus a little exercise.
