Question about Intex Quick-Fill AC/DC

The pump is basically suitable for inflating inflatables such as mats and pools. Whether it is also suitable for balls such as a gym ball depends on the size and valve type of the ball. The pump comes with three different nozzle attachments that should fit most valve sizes. If the Gymball has a standard valve, the pump may work. However, it would be advisable to check the specific requirements of the Gymball to ensure that the pump is compatible.
