(Note: Incompatible with heavy-duty tires, like those on offroad vehicles, RVs, trucks, and trailers.) EASY TO USE: You can choose 5 smart modes (car, motorcycle, bicycle, ball, and custom) and 4 pressure units as needed (PSI, Bar, kPa, kg/cm²) based on your various inflation needs. The custom mode allows you to freely preset the desired pressure value (3-150PSI) based on the inflatables you want to inflate. The exterior silicone sleeve protects against accidental drops, prolonging the tool’s service life. ALL IN ONE TOOL: The air compressor can be used as more than an air pump, it is also a multifunctional emergency tool.
