【FAST PUMPING TYRE】:GSPSCN Heavy Duty Double cylinder design,maximum pressure 150PSI, air flow 70L/min, inflates standard vehicle tyre in 1.5 minutes (200/70/R16, 0-35psi) 【BRIGHT LED LIGHT】: GSPSCN portable 12v air compressor is equipped with bright and long-lasting LED lights, allow easy operation or making quick repairs in the dark and make sure you can be seen in an emergency to avoid any potential dangers. 【LCD DIGITAL PRESSURE GAUGE (with Backlight)】:Tyre pump apart from inflating air, the built-in digital air gauge can also check and monitor tyre pressure with large bright LCD backlit digital display . The gauge is preset pressure shut off gauge with four display units: PSI, KPA, BAR, KG/CM²; Measuring range: 0-150 PSI with precise accuracy of 0.1 PSI. 【ADVANCED ACCURACY】: Professionally calibrated to always return a reading within 1% of the pressure of your tyre. No more guessing! Accurately measures and inflates from 0-150 PSI; The final inflation value will be 0.5-1.5 PSI higher than the preset value; When inflation is finished, it perfectly solves the problem of reduced pressure after removing the valve connector, thus making inflation more accurate. 【Notice】: Please note that if the inflator does not work, please be sure to use the battery clamp. Because the two-cylinder air pump need more powerful current to work.
