Product Features
- Small but Powerful: The air pump delivers 17 cylinders/18 minutes of inflation and can inflate tires from 29 PSI to 36 PSI in less than 1 minute. Inflate up to four 195/55/R15 car tires with just one full charge (0-36psi). Measuring only 8.38*2.08*2.08 inches and weighing 1.1 pounds, the tire inflator can be stored in the side door of your car for an attractive and space-saving solution. A storage bag helps you carry it better when traveling.
- Freedom of Choice: Portable tire inflator for car has four pressure units to choose from, which can be switched between PSI, KPA, BAR, KG/CM² in real time. Suitable for four preset inflation modes: car, motorcycle, bicycle and ball. You can preset the desired value, and the electric air pump will stop inflating tires automatically after reaching it, eliminating worries about over-inflation.
- Two Inflatable Modes: Equipped with USB charging cable and 12V car power cable, the air compressor can provide two inflating modes. You don't have to worry about the battery running out during the trip, it's a good helper for emergencies on the road. Connect the tire inflator to your car's 12V cigarette lighter and inflate your tires directly. There is also an additional USB output port on the cordless tire inflator, which serves as an emergency power source for mobile phones.
- Digital Display and LED Lighting: The dual digital display screen can intelligently detect real-time tire pressure, allowing you to quickly read real-time and preset pressure values. The LED light on the top of the air pump has 3 lighting modes: normal, SOS, and flash, which can become an emergency power source in the dark. The air pump can also work with a safety hammer to break through thick car windows. This multifunctional tire pump increases the chances of survival.
