Demo of the AstroAI Air Compressor Tire Inflator Portable Air Pump for Car Tires on Amazon. I bought this because I was tired of sitting by the tire, waiting for the tires to inflate. Due to many temperature changes in our area, our tires are frequently low on air and need to be refilled. This has made it a lot easier. You can set the PSI to your tire's suggested PSI (see the inside of your car door or your manual), then attach the pump, step back and wait. The device turns off when the PSI is correct.
