A manual balloon pump is a simple device used to inflate balloons without the need for electricity. It typically consists of a cylindrical body with a handle that the user pumps up and down. This action creates suction, drawing air into the pump and forcing it into the balloon through a nozzle. These pumps are popular for parties and events, as they allow for quick and easy inflation of various types of balloons, including latex balloons and mylar balloons. They are portable, lightweight, and often made of durable plastic, making them convenient for both indoor and outdoor use.
