Key Features
- 2X Faster Inflation: Equipped with a 19-Cylinder Design and a built-in 6000mAh (2000mAh*3) rechargeable battery, this inflator delivers up to 20L/min airflow, significantly reducing inflation time. It can inflate a 195/65R15 tire from 30 to 36 PSI in approximately 1.27 minutes.
- Dual-Screen Display: Features a high-precision sensor and large dual digital LED screens that clearly display both real-time and preset pressures. It offers 4 smart inflation modes (car, motorcycle, bike, ball) plus a custom mode with an adjustable range of 3-150 PSI. Easily switch between PSI, KPA, BAR, and KG/CM² pressure units.
- Dual Power Supply & Reverse Charging: Equipped with a rechargeable battery (fully charged in about 4 hours via USB-Type C cable). A 3-meter 12V DC car power supply cord is included for backup, ensuring operation even when the battery is depleted. The device also functions as a power bank for urgent phone charging.
- Auto Shut-Off Function: Automatically stops inflation once the desired pressure is reached, preventing over-inflation. The device also shuts off after 90 seconds of standby to conserve battery. (Note: Incompatible with heavy-duty tires like those on off-road vehicles, RVs, trucks, and trailers.)
- Multifunctional LED Light: Features a top-mounted LED light with three modes (constant light, 0.8s slow flash, 0.4s fast flash) for use in dark conditions, changing tires, or alerting other vehicles at night.
- Hidden Storage Design: A convenient hidden compartment on the back of the unit allows for easy storage of the 3 air nozzles, preventing loss.

Setup
Before first use, ensure the device is fully charged. Connect the USB-Type C cable to the inflator and a compatible 5V/2A USB power adapter (not included). The battery indicator will show charging status.
Initial Setup and Connection:
- Connect Air Hose: Connect the air hose to the top port of the inflator. Ensure it is securely screwed in.
- Attach to Valve: Select the appropriate nozzle if needed (e.g., for bikes or balls) and firmly attach the air hose nozzle to the tire valve core. For car tires, simply clamp the nozzle onto the valve stem.
- Power On: Press and hold the power button (usually the central button) for 3 seconds to turn on the device. The dual-display screen will illuminate.

Operating Instructions
Selecting Inflation Mode and Setting Pressure:
- Choose Mode: Short press the 'M' button (mode button, often indicated by an icon) to cycle through the preset inflation modes: Car, Motorcycle, Bicycle, Ball, and Custom. Each mode has a recommended pressure range.
- Set Pressure Unit: Short press the 'U' button (unit button) to switch between pressure units: PSI, KPA, BAR, and KG/CM².
- Adjust Target Pressure: Use the '+' and '-' buttons to increase or decrease the desired target pressure. The preset value will flash while adjusting.
- Start Inflation: Once the desired pressure is set, short press the power button (central button) to begin inflation. The real-time pressure will be displayed and increase as the item inflates.
- Auto Shut-Off: The inflator will automatically stop once the set target pressure is reached.
- Manual Stop: To stop inflation manually at any time, short press the power button again.
Using the LED Light:
Short press the light button (indicated by a light bulb icon) to cycle through the LED light modes:
- Constant Light
- 0.8s Slow Flash (SOS signal)
- 0.4s Fast Flash (Warning light)
Press the button again to turn off the light.
Using as a Power Bank:
Connect your electronic device (e.g., smartphone) to the USB output port (5V/2A) on the inflator using a compatible USB cable. The inflator will begin charging your device.
Maintenance
- Charging: It is recommended to fully charge the pump before every use to ensure optimal performance and battery longevity.
- Cleaning: Wipe the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the inflator and its accessories in the provided storage bag in a cool, dry place away from direct sunlight and extreme temperatures. Utilize the hidden storage compartment for the nozzles.
- Air Hose Care: Ensure the air hose is not kinked or damaged during storage or use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not turn on. | Low battery or not charged. | Charge the device fully using the USB-Type C cable. If battery is depleted, use the 12V DC car cord. |
| Inflation is slow or not working. | Air hose not securely connected; nozzle not properly attached to valve; item being inflated is too large (e.g., heavy-duty truck tires). | Ensure all connections are tight. Verify the nozzle is correctly attached to the valve. Note that the device is not compatible with heavy-duty tires. |
| Inflator stops before reaching target pressure (for large items like pool floats). | Automatic shut-off after 90 seconds of continuous operation without significant pressure increase (safety feature). | Restart the inflator by pressing the power button. This is normal behavior for items that take longer to inflate. |
| Inaccurate pressure reading. | Sensor calibration issue or improper connection. | Ensure the hose is tightly connected to both the inflator and the valve. If issues persist, contact customer support. |
| Device overheats. | Prolonged continuous use. | Allow the device to cool down for a period before resuming use. The device has overheat protection and will shut itself off. |
