Solar power supply, environmental protection and energy saving: The power of this oxygen pump comes from solar energy, which is environmentally friendly, safe and energy-saving. At the same time, you can adjust the angle of the bracket according to the direction of the sun to ensure that the solar panels can receive solar energy at different times of the day.Powerful oxygen production technology: The aerator produces a large amount of oxygen (the oxygen production is twice that of the ordinary aerator), and it is not afraid of the attenuation of the oxygen production caused by the depth of the water. The powerful oxygen pump greatly increases the water circulation and oxygen in the fish tank, improves the overall water quality of the water environment, increases the health of the water body, and gives your fish a comfortable environment.Robust and simple + quiet design: The aerator is made of high-quality ABS material, and the body is environmentally friendly, durable, simple and stylish. At the same time, it uses noise reduction technology, the working noise is less than 45 decibels, the operation is quiet and stable, and it does not affect the normal rest of you and your family.Large-capacity battery has a long battery life: This aerator has a built-in 3600mAh large-capacity battery, which can work continuously for up to 14 hours after being fully charged. At the same time, the battery has a power storage function, even at night and cloudy days, the aerator can work normally. In addition to solar energy, you can also use a DC power supply to power the aerator through a USB cable to ensure that it can be used normally even if it rains for a long time.Easy to use: Just connect the oxygenator to the oxygen hose and the gas stone, then put the hose and the gas stone into the pool, press the power switch to start working, and press the mode button to select different working modes to control the amount of oxygen (with 3 kinds of oxygen supply modes are available).Specification:Solar panel power: 6V 1.5WBattery capacity: 3.7V/3600mA/hAir pump type: DC micro air pumpRated voltage: 3.0VBath sound: Less than 60dBMaximum airflow: 0.9L/minMinimum airflow: 0.5L/minOperating mode:1.

Long press the power switch (press for 3 seconds), the blue light will be on, and the oxygen will be started. At this time, it is the long-term oxygen mode.2. Press the power switch again (press 1 time) to switch the oxygen mode to intermittent mode, (stop for 2 seconds, and give oxygen for 8 seconds in a cycle mode).3. Charging: Please use the USB2.0 adapter charging head to charge this product. When the voltage is insufficient, the blue light will turn into a red light and enter a flashing state, please charge it in time. Oxygen can also be given while charging.Package list:Aerator 1*Solar panel 1*Oxygen tube 2*Air stone 2 *Note:1.
