2.3 Power Outage Protection
When the unit is plugged into a power adapter, it operates on AC power and simultaneously charges the internal battery. In the event of a power failure, the pump will automatically switch to battery power, ensuring continuous oxygen supply to your aquatic environment. The minimum flow setting can provide up to 100 hours of operation, while the maximum flow can last for approximately 8 hours (based on single air stone experiment).

3. Maintenance
Proper maintenance ensures the longevity and efficient operation of your air pump.
3.1 Air Stone Care
Soak new air stones in water before initial use to ensure optimal bubble diffusion. Periodically clean or replace air stones to prevent clogging and maintain consistent airflow.
3.2 Battery Care
Avoid overcharging the battery. While the unit is designed for continuous charging, prolonged excessive charging can impact battery life. Disconnect the charger once fully charged if not needed for immediate backup.
4. Troubleshooting
If you encounter issues with your air pump, refer to the following common troubleshooting tips:
- No Airflow: Check all hose connections for kinks or blockages. Ensure air stones are not clogged. Verify the unit is powered on and the battery is charged or the power adapter is connected.
- Weak Airflow: Adjust the air volume control knob to a higher setting. Inspect air stones for partial clogging. Ensure the diverter valve outlets are fully open for the desired hoses.
- Unit Not Charging: Confirm the power adapter is correctly plugged into both the unit and a working power outlet. Check the power adapter for any damage.
- Unusual Noise: Ensure the unit is placed on a stable, flat surface. Check for any loose connections or foreign objects obstructing the air intake/outlet.
