The RAVPower RP-PC1084 makes tire maintenance effortless with a large 19-cylinder pump that fills a tire from 2.3 to 2.5 Bar in about a minute. Its one-touch intelligent inflation automatically stops once the target pressure is reached, and simple "+" and "-" buttons let you fine-tune the pressure or switch between PSI and other units. Powered directly from your car's cigarette lighter socket, it needs no batteries and can stay in the car ready for anytime use. Beyond car tires, it's versatile enough for bicycle tires, motorcycle tires, and inflatable balls, backed by a built-in light for low-visibility conditions.
