Imagine the situation when your tire loses air in the middle of nowhere and you have no options other than calling for help. But the main question is why you should worry if you have the 3326 Tire inflator. This compact device has the ability to inflate tires and other items. Even compared to the heavy mechanical pumps this inflator is far more effectual. It also has a pressure gauge to check the tire pressure. This 300 psi pressure gauge machine also has separate compartments to keep all its peripherals in an organized way and the wire which comes with it is long enough to be taken to all the four wheels. And for the power supply, just connect it to the car lighter point.
