Circuit parameters:Operating voltage range: 3.0V-4.25VMaximum working current: 450MADischarge protection voltage: 3.0VCharging protection voltage: 4.25VWorking time: about 22 hoursWithout light controlProduct size: 21.5X17.5X7cm/8.5×6.9×2.8inch[Conversion: 1cm=0.3937 inch, 1inch=2.54 cm]Three Modes:Mode 1: High gear. Green light is always on.Mode 2: Low gear. Dark blue light is always on.Mode 3: Low gear (work for 10 seconds; stop for 10 seconds). Sky blue light is always on.Instructions:1.Connect the bubble stone to the vent hole and put it into the water body that needs oxygenation. The solar cell is facing the sunlight, and there is no obstruction between the solar cell and the sunlight. Press the POWER switch and the oxygen pump starts working.2.This product is an electronic product. The oxygen-increasing part of the device cannot be placed in the water, and the diversion hole cannot be blocked.3.This product is a solar energy product. The charging speed is related to the intensity of sunlight. Regular cleaning of the dirt on the solar cell can improve the charging efficiency.Package Included:1x Solar panel1x Aeration pu
