a device used to inflate sports balls, such as soccer balls and basketballs, by forcing air into them
A ball pump is a small device used to inflate sports balls, like soccer balls, basketballs, or footballs. It usually has a needle attachment that fits into the valve of the ball. The pump works by pushing air into the ball to increase its pressure, making it firm and ready for use. Ball pumps are commonly used by athletes, coaches, and anyone who needs to keep sports balls properly inflated for games and practice. Some pumps are manual, while others are powered by electricity or batteries for quicker inflation.
