1. Inflating: The portable tire inflator uses a pure copper motor and advanced airflow boosting technology that allows tires to inflate in just 10 seconds, making it an essential tool for quick breakdown assistance. 2. For precision measurement: With a precision intelligent chip, this air compressor provides accurate pressure measurements, enabling users to adjust the desired inflation level and automatically stop once reached, ensuring safety and preventing overinflation. 3. Automatic functionality: This multifunctional pump is designed for convenience, allowing users to set the desired tire pressure and automatically stop inflation at the correct level, while its removable inflation hose prevents air leakage. 4. Digital LCD display: The builtin digital LCD pressure gauge offers realtime monitoring of both current and preset pressure, enhancing ease of use and helping users maintain tire conditions with clear, visible measurements.
