Versatile use: Place this water fountain in the bird bath, pool, pond or other water to create a beautiful water decoration. Solar Powered: The fountain is powered by solar cells and therefore requires no batteries or electricity. The fountain only needs a few seconds of direct sunlight to start working. It sprays about 10 - 20 cm up into the air depending on how bright sunlight is on it. Different nozzles: You can choose from different interchangeable nozzles to have different effects on the water sprayed. Keep in mind that the pump for the fountain must be covered in water for it to work. Note: 1.This product is a solar powered water pump without an external battery.The height of the water jet depends entirely on the strength of the sun. When the sun is weak, the pump will not work continuously but will automatically start repeatedly until it has received enough energy to return to its continuous working mode. Place the product in direct and free sunlight. In case of shade, the pump does not receive enough energy for normal operation. 2.The pump must be completely immersed in the water and the water pump should be cleaned regularly. 3.Handle the water fountain carefully as the solar panel is very sensitive.
