3. Setup
3.1 Charging the Inflator
Before initial use, fully charge the inflator. Connect the provided Type-C cable to the inflator and a suitable 5V 1.5A charger. A full charge takes approximately 30 minutes. The indicator light will flash red during charging and turn green when fully charged.

3.2 Valve Compatibility and Attachment
The AS2pro supports both Presta and Schrader valves without needing extra accessories. The unique nozzle design allows for effortless switching.
- For Schrader Valve: Ensure the seal part has the big hole outward.
- For Presta Valve: Ensure the seal part has the small hole outward.
When inflating, press the inflator firmly against the valve and adjust its position to prevent air leakage. For TPU valves, always use the extended hose.


4. Operating Instructions
4.1 Inflation Process
The AS2pro features an auto-stop function. You can set or adjust the desired pressure, and the pump will automatically stop once the preset value is reached. The LED screen provides a real-time display of the pressure, battery level, and allows you to switch between BAR and PSI units.


4.2 Performance
The AS2pro offers powerful inflation, capable of refilling a 700*25C road bike tire (0-80 PSI) in just 52 seconds, and inflating it from 0-120 PSI in 120 seconds.


5. Maintenance
5.1 General Care
The AS2pro is equipped with a silicone insulation case and a splash-proof pouch. Use the silicone case during operation to prevent burns from continuous injections and to protect against overheating. The splash-proof pouch allows for use in light rain conditions.

5.2 Battery Longevity
The AS2pro utilizes balanced charging technology to enhance durability, allowing it to withstand over 200 charging cycles with less than 10% battery degradation.
6. Troubleshooting
- Air Leakage During Inflation: Press the inflator firmly against the valve before and during inflation. Adjust the position to ensure a tight seal.
- Inflator Gets Hot: It is normal for the inflator to get warm during operation. Always use it with the provided silicone case to manage heat.
- Traction When Removing from Presta Valve: A slight sense of traction when pulling the inflator off a Presta valve after inflation is normal.
- TPU Valve Inflation: Do not inflate TPU valves without using the extended hose.
