The Astro AI S1 portable air compressor features a real-time tire pressure display on an LCD screen, eliminating the need for mechanical gauges. The Astro AI S1 also teaches real-time tire pressure, making readings more accurate and convenient. It offers four available units of measurement: psi, kPa, bar, and kg/cm². Once the preset pressure is reached, the Astro AI S1 portable air compressor automatically shuts off, eliminating concerns about over-inflation. To inflate, after starting the engine, plug the cigarette lighter plug into a 12V car power outlet, attach the tire, and press the buttons to set the desired pressure. For 185/55 R14 tires, the Astro AI S1 portable air compressor can increase air pressure from 0 psi to 36 psi in 5 minutes and from 30 psi to 36 psi in 1 minute. Note: The device can operate continuously for 15 minutes. The Astro AI S1 portable air compressor comes with a 0.5-meter hose and a 3-meter power cord for easy connection to any tire. A built-in LED light helps ensure smooth operation in emergencies and dark environments. The LED will illuminate when the digital tire inflator is switched on. Caution: This type of corded air compressor can only be charged using a car cigarette lighter socket. Package contents include 1 S1 portable air compressor, 2 nozzles, 1 needle valve adapter, 1 Presta Schrader adapter, and 1 spare fuse. The S1 portable air compressor is compatible with EU standards.
