Specifications: Solar panel power: 7V, 160MA Solar panel size: 11*11cm Brushless pump input: DC 4.5-10V Pump flow: 150-200L H Lifespan: 20,000 hours Delay: 3s Color: Black Net weight: 190g Package includes: 1 * Solar fountain 1 * Small parts for assembly Restart: when the sunshine is off, can restart within 3 seconds when the sunshine is back. Quick overview: The product is based on updating brushless solar pump technology products that overcome the disadvantage of hard start, low efficiency, low stability of similar products and it can start even easier than the same power brush pump. Features: Use solar energy, no extra power supply required, energy saving and environmentally friendly. Polycrystalline silicon. High quality. Quick start. High efficiency. Consistent performance. Easy to use and operate. Long lifespan. Note: Products of direct-acting solar-powered water pump, it does not need external batteries, a high water level depends entirely on the sun, when the daylight is weak the water pump does not work steadily, when the daylight gets stronger it would automatically continue to work. Solar panels and controllers are not submerged in water, although it has a weak waterproof structure, but it is not suitable for long-term immersion in water. The appearance of the solar panel may show a slight difference, but it has no impact on use. Please advise in kind. KLB Store
