4. Setup Instructions
4.1 Component Identification
Image 4.1: Overview of the air pump components and controls.
4.2 Connecting Air Tubes and Air Stones
- Cut the air tube to the desired length.
- Connect one end of the air tube to an air outlet on the pump.
- Connect the other end of the air tube to an air stone.
- Place the air stones in your aquarium.
4.3 Installing Check Valves (Recommended)
If the air pump is placed below the water level of your aquarium, it is crucial to install check valves to prevent water from siphoning back into the pump during a power outage, which can cause damage. The package includes two check valves.
- Cut the air tube from the middle or any suitable position between the pump and the air stone.
- Insert the check valve into the cut section of the air tube. Ensure the arrow on the check valve points towards the air stone (away from the pump), indicating the direction of airflow.
- Connect the air tubes to the air pump and check valve respectively.
- Connect the other end of the air tube to the air stone.

4.4 Charging the Air Pump
The air pump is equipped with a rechargeable lithium battery. Before first use, fully charge the pump. Use the provided USB charging cable to connect the pump to a USB power source such as a USB charger, power bank, car USB charger, or computer USB port.

5. Operating Instructions
5.1 Power ON/OFF
Press the ON/OFF switch (refer to Image 4.1) to turn the pump on or off.
5.2 Working Modes and Airflow Adjustment
The pump offers two working modes and four adjustable airflow levels:
- Continuous Mode: Provides constant airflow. Press the 'M' button (Working Mode Indication Key) to select this mode.
- Intermittent Mode: Provides airflow in intervals, conserving battery life. Press the 'M' button to cycle to this mode. A blinking light indicates intermittent mode, while a constant light indicates normal (continuous) mode.
To adjust the airflow level, press the 'Flow Adjustable Button' (up/down arrows). There are four levels, typically indicated by a flashing light on the battery indicator. A constant light on the indicator shows the power level.

5.3 Battery Indicator
The indicator lights on the pump serve a dual purpose:
- When adjusting airflow, a flashing indication shows the air flow rate level.
- When not adjusting airflow, a constant light indicates the current battery power level.
5.4 Runtime
The 4W-2600mAh model offers the following approximate runtimes on a full charge:
- Maximum Continuous Mode: 16 hours
- Minimum Continuous Mode: 30 hours
- Maximum Intermittent Mode: 31 hours
- Minimum Intermittent Mode: 58 hours

6. Maintenance
6.1 Cleaning Air Stones
Over time, air stones can become clogged with algae or debris, reducing airflow. Clean them regularly by soaking them in a diluted bleach solution (e.g., 1 part bleach to 9 parts water) for a few hours, then rinse thoroughly and soak in dechlorinated water before reintroducing to the tank.
6.2 Checking Air Tubes
Inspect air tubes periodically for kinks, cracks, or blockages. Replace damaged tubes to ensure optimal airflow.
6.3 Battery Care
To prolong battery life, avoid fully discharging the pump frequently. Recharge the pump when the battery indicator shows low power. If storing the pump for an extended period, charge it to approximately 50% and recharge every 3-6 months.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No air output | Pump is off; Battery is depleted; Air tube kinked/blocked; Air stone clogged; Check valve installed incorrectly. | Turn on pump; Recharge battery; Straighten/replace air tube; Clean/replace air stone; Verify check valve direction. |
| Low air output | Airflow setting too low; Air stone partially clogged; Air tube partially blocked; Low battery. | Increase airflow setting; Clean air stone; Check air tube for partial blockages; Recharge battery. |
| Excessive noise | Pump not on a stable surface; Vibrations; Internal issue. | Ensure pump is on a flat, stable surface; Check rubber feet for damage; Contact support if noise persists. |
| Pump does not charge | USB cable faulty; Power source faulty; Charging port damaged. | Try a different USB cable; Try a different USB power source; Contact support. |
