The Ring Automotive Cordless Digital Tyre Inflator allows you to inflate your car, motorcycle, bicycle tyres or small inflatables easily and quickly. Its compact size and robust design make it easy to store in your vehicle for use anywhere. The backlit digital screen simplifies setting tyre pressure, and it can inflate a 15-inch tyre from flat in under 6 minutes. The RTC4000 features a digital autostop function that halts inflation once the desired pressure is reached. The inbuilt memory can store up to 4 tyre pressures in PSI, BAR, or kPa. A deflator valve is included for accurate pressure adjustment. A powerful, built-in LED light is useful in emergencies, regardless of lighting conditions. It comes with a 3-piece adaptor kit for small inflatables like sports equipment and Presta bike valves.
