Tire inflator is a tool used to inflate tyres. It comes with a gauge that shows how much air is in the tyre and a line that connects to the tyre valve. Simply connect the hose to the valve and turn on the tyre inflator to use it. The tire's air pressure will begin to build up, and the gauge will indicate this. Simply shut off the tire inflator and unplug the line once the tyre has the desired quantity of air in it. The necessary tyre pressure is restored by using this product that is connected to the 12V power outlet.
