AstroAI S1 Portable Tire Inflator 150 PSI 12V DC Digital Air Compressor with Preset Pressure Auto Shut Off and LED Light

The AstroAI S1 Portable Tire Inflator is a compact 12V DC air compressor designed for convenient tire inflation at home, in the garage, or during roadside emergencies. It provides a maximum pressure of 150 PSI and features a digital pressure display with preset pressure control. Users can set the desired tire pressure, and the inflator will automatically stop once the target pressure is reached, helping reduce the risk of over-inflation. AstroAI officially identifies the S1 as the 150 PSI digital-screen and auto-shutoff model in this product family. The S1 is powered directly from a vehicle’s 12V DC socket and is suitable for cars, motorcycles, bicycles, sports balls, and other compatible inflatables. Its compact design makes it easy to store in a vehicle trunk or garage, while the integrated LED light improves visibility during nighttime or low-light use. The unit also includes multiple inflation adapters, allowing it to work with different valve types and inflatable products. Its preset pressure function, real-time digital display, and automatic shut-off make it a practical choice for routine tire-pressure maintenance and emergency use.
