Portable Digital Wireless Car Tire Inflator

• Wireless and Rechargeable: This is the defining feature. It uses a built-in rechargeable Lithium-ion battery (often ranging from 2000mAh up to 6000mAh or more).² This makes it entirely cordless, eliminating the need to connect to a car’s 12V cigarette lighter for every use.

   

• Compact and Lightweight: Designed for portability, it’s typically small enough to fit in a glove box, center console, or tool bag, making it a perfect emergency or routine maintenance tool.³

   

• Charging: Usually charged via a standard USB-C or Micro-USB cable.⁴ Some models also include a 12V DC power cord for charging or use when the internal battery is depleted.⁵

   

🎯 Digital Functionality and Safety

• Digital Pressure Gauge (Digital Display): It features a bright, easy-to-read LCD or LED digital screen.⁶ This displays the current tire pressure and the target pressure.⁷

   

• Automatic Shut-Off: A crucial safety and convenience feature.⁸ The user presets the desired tire pressure (e.g., 35 PSI).⁹ The inflator will automatically stop once the pressure reaches that preset value, preventing over-inflation.

   

• Multiple Pressure Units: The display usually allows switching between standard measurement units, such as PSI (Pounds per Square Inch), BAR, KPA (Kilopascals), and sometimes ¹⁰$kg/cm^2$.¹¹

   

• Tire Pressure Monitoring: When connected to the tire valve, the device can display the tire’s current pressure, effectively acting as a digital tire gauge.¹²
