Battery parameters: Rechargeable lithium battery pack: 3.7V 1800mAh In the case of sunlight, the solar panel can supply power to the water pump at the same time, and the excess electricity will directly charge the battery. When there is sunlight, the colorful breathing light will not light up. In the absence of sunlight, the battery can be fully for 4 hours (continuously spraying water to keep the light on) Battery life: more than 500 cycles of charging. Startup: For the first use, when the water pump receives sufficient sunlight, the water pump will start up within 3 seconds. In order to the battery life, 30% of the battery will be retained during each battery discharge, and the battery will be less than 30% of the storage capacity. Electricity, the battery does not work, it is recommended to take the fountain out of the water and put it in the sun for fast charging. Adopt brushless motor, long service life and low failure rate. Electric energy diversion and battery power supply function, 70% of the solar energy is converted into electric energy during the day to supply power to the fountain, and 30% to charge the battery. The batteries power the fountains and lights at night. With the same volume, the power of the solar panel is increased by encrypting the density of the monocrystalline silicon wire. 7 colored LED lamp beads, automatically start the lighting function after the sun goes down, and the lighting mode is automatic breathing mode. With four to prevent the wind from blowing the fountain to the shore of the pond during use (the length of a single strut is 10CM). Specifications of solar panels: Solar panel voltage: 4.5V Solar panel power: 3.5W Solar panel size: 160mm (diameter 160MM,) Number of colorful lights: 7 LED breathing colorful lights (automatically change color) Specifications of the water pump: Water pump voltage: DC 4.5V Water pump power: 1.0W Whether the water pump is equipped with anti-dry burning: With, anti-dry burning is integrated with the control board; Maximum lift: 130cm Maximum flow: 240L/H Maximum height: 60CM Colour: black Material: plastic Package Contents: 1 * Solar water pump 6 * Nozzle 4 * Anti-collision strut Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
