Product Features
Powerful Airflow
The pump delivers a maximum air flow rate of 2.5 Liters Per Minute (LPM) and a pressure of 0.015 MPa. It is suitable for aquariums ranging from 5 to 30 gallons, providing sufficient aeration and water circulation.

Rechargeable Battery & Automatic Power Switching
Equipped with a built-in 2600mAh lithium-ion battery, the pump offers two working modes:
- Normal Mode: Provides 22-25 hours of continuous operation.
- Intermittent Mode: Provides 27-30 hours of operation (runs for a few seconds, then pauses).
The pump supports both AC and DC power. When connected to AC power, it functions as a standard air pump. In the event of a power outage, it automatically switches to the internal lithium battery DC power supply, ensuring continuous aeration for your aquatic environment.
Ultra-Quiet Operation
Designed with 4 shock-absorbing feet, the pump minimizes vibration and noise. At its lowest flow rate, the noise level is approximately 35dB, comparable to rustling leaves or a ticking watch, promoting a peaceful environment for both you and your pets.

Versatile Applications
This portable air pump is suitable for various uses, including:
- Home aquariums and fish tanks
- Outdoor fishing
- Live bait aeration
- Emergency aeration during power outages
- Transportation of aquatic life

Connecting Components
- Connect Air Tubing: Insert one end of the air tubing firmly into the air outlet port on the pump.
- Attach Air Stone: Connect the other end of the air tubing to an air stone. Ensure a snug fit.
- Install Check Valve (Important for below water level placement): If the air pump is placed below the water level of the aquarium, a check valve must be installed on the air tubing between the pump and the air stone. This prevents water from siphoning back into the pump during a power outage, which can damage the unit. Ensure the check valve is oriented correctly, allowing air to flow from the pump to the air stone, but not water back to the pump.

Placement
Position the air pump in a stable location. If the pump is placed below the water level of the aquarium, ensure the check valve is correctly installed to prevent back-siphoning. For optimal performance and safety, it is generally recommended to place the air pump above the water level.

Operating Instructions
- Power On/Off: Press and hold the power button (indicated by a circle with a vertical line) for approximately 3 seconds to turn the pump on or off.
- Switch Modes: Once the pump is on, short press the power button to toggle between Normal Mode (continuous aeration) and Intermittent Mode (aeration with pauses). The intermittent mode indicator light will illuminate when this mode is active.
- Battery Indicator: The battery indicator lights will show the current charge level of the internal battery.
Charging Instructions
The KEDSUM air pump is rechargeable via its Type-C USB port.
- Connect Charging Cable: Insert the Type-C end of the charging cable into the pump's charging port.
- Connect to Power Source: Connect the USB-A end of the charging cable to a compatible 5V USB power source, such as a laptop, a wall charger (5V output), or a power bank.
- Charging Indicator: The battery indicator lights will show the charging status. They will typically blink while charging and remain solid when fully charged.

Maintenance
- Keep Dry: The pump is not waterproof. Avoid water intrusion, especially saltwater, as it can damage internal electronics.
- Clean Air Stones: Periodically clean or replace air stones to ensure optimal bubble production and airflow. Clogged air stones can reduce pump efficiency.
- Tubing Inspection: Check air tubing regularly for kinks, blockages, or damage.
- Storage: When not in use for extended periods, fully charge the pump and store it in a cool, dry place.
