Key benefits Fast, reliable inflation: High-speed pump inflates standard mid-size car tires from 0 to 35 in 3–5 minutes, saving time compared with manual pumps. Hands-free accuracy: Set the target pressure and the unit automatically shuts off when the preset value is reached, preventing overinflation and removing the need for constant monitoring. Clear, accurate readings: Large digital screen displays real-time pressure for precise inflation and avoids the reading errors common with dial gauges. Ready-for-emergencies: Built-in LED light and long power/cable reach make roadside use safer and easier at night. What it does and why you need it Inflates tires quickly and accurately so you can get back on the road with correct tire pressure. Eliminates guesswork and reduces the risk of under- or overinflation by showing live pressure and stopping automatically at the preset value. Compact and portable for storage in your trunk; practical for routine maintenance and unexpected flat or low-pressure situations. Key features and specifications Inflation speed: inflates standard mid-size car tires from 0 to 35 in 3–5 minutes. Automatic shutdown: stops inflation when preset pressure is reached for safe, worry-free use. Continuous operation limit: can operate continuously for up to 10 minutes. Digital display: large screen shows real-time pressure for more accurate readings than dial gauges. Preset controls: set the required pressure using "+" and "-" buttons; the pump shuts off automatically at the preset value. Power and connection: plugs into the vehicle 12V lighter outlet; start the engine before use. Hose and cord length: 0.48 meter air hose and 3 meter power cord for easy reach to any tire. LED light: integrated emergency light turns on when the inflator is activated for night or low-light use. How to use (simple steps) 1. Start the car engine. 2. Plug the lighter plug into the 12V outlet. 3. Connect the air hose to the tire valve. 4. Use the "+" and "-" buttons to preset the desired pressure. 5. Start the inflator; the digital screen will display real-time pressure and the LED will illuminate. 6. The pump will automatically stop when the preset pressure is reached. Practical use scenarios Roadside emergency: Recover from a low-pressure or flat tire on the side of the road—connect, preset, and let the pump run while the LED helps you work in the dark. Pre-trip check: Quickly top up tire pressure for safer handling and improved fuel efficiency before a long drive. Routine maintenance at home: Keep accurate tire pressure across all four tires without trips to a gas station compressor. Compatibility and considerations Designed for use with standard mid-size car tires and vehicles with a 12V lighter outlet. Intended for short inflation cycles; maximum continuous operation is 10 minutes—allow cooling between extended uses. Preset and digital display features reduce the need for manual pressure checks, improving convenience and safety. What makes this inflator stand out Combines speed, real-time digital monitoring, and automatic shutdown to deliver a safer, more convenient inflation experience. Long power cord and air hose plus an integrated LED light extend usability in real-world situations, including night-time and roadside use. Package usage tips Always start the vehicle engine before operating the pump to avoid draining the battery. Verify the preset pressure matches your vehicle manufacturer’s recommended tire pressure. For multiple tires, allow the unit to cool if it approaches the 10-minute continuous runtime. This tire inflator is a practical, easy-to-use tool for fast, accurate tire inflation, emergency roadside use, and routine maintenance.
