Air pumps are devices used to move air in and out of various objects, such as tires, balloons, and inflatable toys. They can be powered manually or electrically, making them versatile for different applications. Manual air pumps often require physical effort, while electric pumps can quickly inflate or deflate items with the push of a button. These pumps come in various types, including hand pumps, foot pumps, and electric pumps. Each type has its own advantages, such as portability or speed. Air pumps are essential tools for maintaining proper air pressure and ensuring the functionality of inflatable products.
