High Performance: The maximum pressure of this cordless air pump is 150 PSI. The powerful motor produces 25 liters of air flow per minute. Inflates a car tire (195/55R15) from 0 to 2.48 bar in 4 minutes and 30 seconds, and a road bike tire (700x28C) from 0 to 120 PSI in 4 minutes and 13 seconds. Wide range of applications: This cordless compressor comes with 4 accessories (Schrader valve, Presta valve, needle valve, air valve) and 4 pressure units (Psi, Bar, Kpa, Kg/Cm). By connecting the pump to the tire, you can measure the tire pressure accurately. Smart inflation: The desired tire pressure can be set before use. When the preset pressure value is reached, the cordless compressor will automatically shut off to avoid over-inflation.
