This is the device that patches and inflates a flat tire in 10 minutes without requiring you to lift the car or remove the tire. Its built-in compressor pumps air and the included sealant through the flat tire's air valve to simultaneously patch and inflate the tire. The patented water-based nano-fiber sealant patches holes up to 1/4" wide and a built-in pressure gauge helps you determine when the tire is inflated to its optimal air pressure. It plugs into a car's DC outlet with an 11' cord and all components are housed in a lunch box-sized container that stores unobtrusively inside a car. The device can be used just for inflation and includes attachments for bicycle tires and sports balls. Patched tires can be driven up to 125 miles. Additional sealant available below. 10 1/2" L x 8" H x 4" W. (5 lbs.)
