All-in-one 250PSI Tire Inflator Gauge The tire inflator gauge makes filling tires extremely easy when using an air compressor. Instead of filling a tire by checking the pressure, adjusting, and repeating, simply press the handle of tire inflator gauge down to fill the tire to the exact pressure you want and then release the handle, it will stop filling. Besides, the tire inflator comes with an extra inflation needle and cone inflation adapters thus can quickly inflate balls, air pillows, cushions and mattresses for your convenience.

AstroAI S1Pro Portable Car Tyre 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 tyre pressure from 30 PSI to 36 PSI in 1 minute (tested on 205/55 R16 and 225/45 R17 tyres), 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 tyres, 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.
