The power of the air pump is determined by the type of vehicle. Therefore, when purchasing the vehicle mounted air pump, small cars can choose the one with low power on the horizontal bar, which is cheap and energy-saving, and is enough; But large SUVs and other off-road vehicles, medium and large cars need to use parallel bars high-power inflation pump, otherwise the inflation is very slow, and it costs electricity.

2. Inflation speed.

General vehicle inflation pump inflation speed is different, low power inflation slow, high power inflation fast. If the car's tires are large, it is recommended to use a high-power inflation pump. The inflation speed is faster. Generally, those above 225 are suitable for high-power ones, and the inflation speed is above 35L per minute. Pay attention to the inflation speed when purchasing.

Connector is the most commonly used part of air pump, so its quality is very important. Good quality vehicle air pump is made of pure copper connector, which is durable. Even if you accidentally step on it, it's OK. Poor quality is ordinary iron, which is easy to deform. You should see clearly when you buy it.

5. Whether it is convenient to take up the air pump.

The inflatable pump circuit is generally long, about 3 meters. If it is folded up casually, it will easily lead to premature aging and damage of the circuit. Therefore, if the inflatable pump has a special groove to collect the circuit, it will be much better, which can greatly extend the life of the circuit.

6. Whether a tool kit is provided.

If the vehicle mounted inflatable pump is equipped with a tool kit, it will be more practical. When purchasing the inflatable pump, try to buy a combined tool kit, which is more convenient to use. With the kit, the air pump is more convenient to carry.
