【Quick and Efficient Inflation】Equipped with a high-performance chip, the tire inflator portable air compressor delivers powerful high-velocity airflow—boasting an impressive 36L/min inflation rate, twice as fast as regular tire inflators. This allows you to finish inflating quickly, with a maximum pressure of 180 PSI 【4+N Smart Modes】The air pump offers four pressure measurement units: PSI, KPA, BAR, and kg/cm². It also provides four preset inflation modes: bicycle, motorcycle, car, and ball. The fifth manual mode allows you to customize the pressure according to the specific inflation target. It is extremely convenient for both daily life and travel needs 【Accurate LCD Screen & Automatic Stop】The large LCD display shows preset values and real-time pressure values, making it easy to monitor and operate at any time. At the same time, you can preset and monitor tire pressure with it, and the air compressor will automatically shut off when the set pressure is reached, preventing over-inflation 【Multifunctional Emergency Tools】In addition to serving as a tire inflator, it is also a practical emergency tool. It features an LED light with 3 modes at the top, which can be used to illuminate dark areas or warn other vehicles at night. There’s also a 5V/2A USB output/input port, allowing it to serve as an emergency power source for electronic devices 【Upgraded Radiator】This portable air compressor adopts acoustic noise reduction technology, with a noise reduction structure that can reduce the noise to as low as 40 dB. The built-in control chip and spiral fan enhance effectively the heat dissipation speed, while the arrangement of cooling holes further increases the heat dissipation area
