FAST INFLATION AND ACCURATE PRESSURE]: The tire inflator uses a powerful motor to bring you an efficient experience. It can inflate tires from 0 psi to 35 psi in 5 minutes and 30 seconds. Different objects need different PSI, such as car tires 70PSI, motorcycle 80PSI, bike 100PSI. For reference only. COMPACT & PORTABLE The inflatable portable air compressor is lighter in weight, smaller in size and narrower in body, which makes it easy for you to put it anywhere in your car. Meanwhile, it comes with an 11.5-inch (about 28.9 cm) long power cord, which can be placed anywhere you want to inflate. [Multi-functional, Easy to Use]: The air compression tire pump supports 4 units of pressure measurement - PSI, KPA, BAR, KG/CM. It is also equipped with LCD digital display and LED headlight support warning mode and SOS mode, so you can use it easily in the dark. You can plug the air pump into your car's cigarette lighter socket, set the default air pressure value, then gently press the switch to turn on the air pump, and that's it. Widely ApplicableThe portable air compressor comes with two extra nozzles, which can be used to inflate car/bike tires, as well as other inflatable equipment such as inflatable mattresses, inflatable boats, balls and so on.
