The car air pump is also called the portable tire inflator or car air compressor, which works with the operation of a motor. When pumping air, the valve of the communicating device is opened by atmospheric pressure, and the gas enters into the cylinder; when the tire is pumped, the valve is closed by the air pressure in the cylinder, and then the gas enters the tire.
Advantages of the car air pump:
1. Small size, usually put in the trunk of a car, does not occupy space, and is easy to carry.
2. High power, good efficiency and fast inflation speed.
3. It can be used in automobiles, motorcycles, bicycles, swim rings and balls, etc., with a wide range of applications.
4. It can be used to measure the tire pressure so that the car tires can maintain normal tire pressure at any time.
