air pumps
An air pump is a device used to inflate or deflate objects by moving air in or out. Commonly used for inflating balloons, bicycles, and air mattresses, air pumps can be manual or electric. Manual pumps require physical effort, while electric pumps operate with a motor, making them faster and easier to use.
Air pumps work by creating a pressure difference, allowing air to flow into or out of an object. They are essential tools in various activities, from sports to camping, ensuring that items are properly inflated for optimal performance and comfort.
