The portable tire pump from VEVOR offers quick and efficient inflation. With 19 cylinders, a maximum pressure of 160 PSI, and enhanced power, it inflates twice as fast as other pumps. In just 1 minute, you can inflate a 205/55 R16 tire from 80% to 100% pressure. Powered by high-capacity batteries (3x2600 mAh), it can inflate approximately 12 tires (225/60 R18) or 18 tires (175/70 R14) from 80% to 100% pressure with a single full charge. A DC 12V power cable (3 m) is also included for connection to your vehicle's power source. With the built-in real-time tire pressure monitoring, you will have precise control over the inflation time and pressure. Set the desired pressure and it stops automatically when achieved. Say goodbye to over-inflation, tire damage, and constant gauge monitoring.
