6. Air pump bath sound: less than 60dB
7. Air flow: 0.5-1L/min

Circuit parameters:
1. Working voltage range: 3.0V-4.25V
2. Rated operating current: 150MA
3. Discharge protection voltage: 3.0V
4. Charging protection voltage: 4.25V
5. Working mode: third gear (continuous third gear oxygenation, continuous low-level oxygenation, intermittent oxygenation for 10 seconds and stop for 10 seconds, repeat cycle)

Instructions for use:
Connect the air stone with the vent hole and put it into the water body that needs oxygenation. The solar panel faces the sunlight, and there is no obstruction between the solar panel and the sunlight. Press the POWER switch, and the oxygenation pump will start to work

Things to note:
1. This product is an electronic product. The main part of the oxygen booster cannot be placed in water, and the diversion hole cannot be blocked.
2. This product is a solar product, please face the solar panel to the sun, and ensure that there is no shelter between the solar panel and the sun. The charging speed is related to the intensity of sunlight. Regularly cleaning the dirt on the solar cells can improve the charging efficiency
