The market umbrella is green, not only for its color, but its solar panels that can convert sunlight into electricity! Four 10" x 4 1/4" solar panels woven into the umbrella's 9' diameter canopy. The produced electricity is accessed via two USB ports in its pole. There is a rechargeable 3.7-volt/1,000mA backup battery provides power in overcast conditions, ensuring smartphones and tablets have an uninterrupted supply of power.
