High performance: This battery-powered air pump delivers a maximum pressure of 150 PSI. The powerful motor provides an airflow of 25 liters per minute. It inflates a car tire (195/55R15) from 0 to 2.48 bar in 4 minutes and 30 seconds, and a racing bike tire (700x28C) from 0 to 120 PSI in 4 minutes and 13 seconds. Wide range of uses: This portable compressor includes 4 accessories (Schrader valve, Presta valve, needle adapter, air nozzles) and supports 4 pressure units (PSI, Bar, KPa, kg/cm²). By connecting the inflator to the tire, you can accurately measure tire pressure. Intelligent inflation: Set the desired tire pressure before use. Once the preset pressure is reached, the compressor automatically shuts off to prevent over-inflation. Easy to use: The electric pump features a large backlit display for clear reading in low light or direct sunlight. A built-in flashlight on the top provides additional illumination for nighttime use. Large capacity battery: The cordless air pump has a built-in 4000mAh lithium battery, rechargeable via a Type-C port. When fully charged, it can inflate up to 2.5 car tires (175/55R15, 0–36 PSI), 7 road bike tires (700x28C, 0–100 PSI), 24 mountain bike tires (0–45 PSI), or 10 motorcycle tires.
