Smart Digital Display: This electric air pump features an LED screen to display the current and preset tire pressure in real time. It automatically shuts off when the desired tire pressure is reached to prevent overcharging and ensure ease of use. Powerful Inflation Performance: Equipped with a 6000mAh battery, the maximum pressure is 150 PSI and the airflow is 45 L/min. It's perfect for inflating cars, motorcycles, balls, swim rings, and inflatable toys, and you don't have to worry about charging. Multiple Inflation Modes: Supports 4 pressure units (PSI, BAR, KPA, KG/CM²) and multiple inflation modes (bikes, cars, balls, etc.); automatically shuts off after 3 minutes of inactivity to conserve power. Portable Design: It's small and lightweight (80 × 48 × 165 mm), making it easy to store and carry. Built-in SOS LED light, suitable for nighttime use and emergency rescue. Inflating a car tire: 1. Starting the device: Press the start button to start the compressor. 2. Connecting the nozzle: Securely attach the nozzle to the tire valve, ensuring there are no air leaks. 3. Adjusting the pressure: Use the button to select the desired pressure and adjust it precisely on the screen. 4. Starting inflation: Press the start button and the compressor will begin inflating. 5. Monitoring the pressure: The screen displays the current pressure in real time to ensure the set value is reached. 6. Stopping inflation: Once the desired pressure is reached, the compressor will automatically stop. The tire is now ready for use, and you can continue driving. Warnings Regarding Compressor Use: 1. Not Suitable for Large or Heavy Vehicles: The compressor is suitable for regular cars, bicycles, motorcycles, and various medium-sized balloons, but is not suitable for inflating heavy vehicles such as large trucks or SUVs to avoid inefficiency or damage to the device. 2. Noise and Heat During Inflation are Normal: During use, the compressor may make noise, and the exterior may become hot. These phenomena are normal. Use the device with caution and avoid direct contact with hot parts to minimize the risk of burns. 3. Pay Attention to Safety During Inflation: Ensure the device is properly connected to the inflatable object to prevent detachment, which could affect inflation efficiency or cause injury. 4. Do Not Use for Prolonged Periods: It is recommended not to use the compressor for more than 10 minutes at a time to avoid overheating and potential damage. After prolonged use, allow the compressor to rest for at least 10 minutes before using it again. 5. Keep the unit dry: The compressor is not waterproof; do not use it in humid environments or in the rain to avoid power outages. 6. Correct pressure setting: Before inflating, set the appropriate pressure according to the type of inflatable to avoid under- or over-pressurization and ensure the lifespan and safety of the inflatable. 7. Check the battery status: Ensure the compressor's built-in battery is fully charged to guarantee efficient inflation. If the battery is low, charge the unit before use to avoid interruptions.
