AstroAI S1Pro Portable Car Tire Inflator combines compact dimensions (13x16x6cm, 623g) with an expansive LCD screen that automatically illuminates upon connection, providing real-time pressure monitoring for effortless tracking during inflation. Engineered for efficiency, it rapidly boosts tire pressure from 30 PSI to 36 PSI in 1 minute (tested on 205/55 R16 and 225/45 R17 tires), achieving a full 0-36 PSI inflation in 5 minutes, making it ideal for British sedans, compact SUVs, and MPVs while requiring cooling breaks after 15 minutes of continuous operation. Its intelligent preset system enables automatic shutoff upon reaching user-defined pressure levels (supports kPa/PSI/BAR/KG/cm² units), eliminating over-inflation risks. The 3-meter power cord and 48cm reinforced hose ensure easy access to all tires, complemented by an integrated emergency LED light for low-light conditions. Versatility is enhanced with included adapters for cars, motorcycles, bicycles, and sports equipment, while a spare fuse and detailed manual ensure long-term reliability. Backed by a 2-year warranty, this all-in-one solution merges portability with professional-grade performance for both routine maintenance and emergency scenarios.
The large digital screen displays the tyre's real-time pressure for a more accurate and intuitive experience. Avoids pressure reading errors common with dial tyre pumps.
This tyre inflator will automatically shut off once it reaches the preset value, no need to babysit the inflation process and worry about overinflation. To inflate: just start the engine, insert the cigarette lighter plug into the car's 12 V outlet, connect the tyre, and preset the desired pressure by pressing "+" and "-".
For tyres with the specification of 185/55 R14, this car tyre pump can inflate from 30 PSI to 36 PSI < 1 min, and can fully inflate a tyre from 0 PSI to 36 PSI < 5 mins. (Note: It can continuously work for 15 mins.)
With a 0.48 m long air hose and a 3 m long power cord, the car tyre inflator is easily connected to any tyre. The integrated LED light is great for emergencies and working in dark environments. When the digital tyre inflator is powered, the LED light will illuminate.
