“This is the only market umbrella that extends the battery life of mobile devices, so you can frolic longer outdoors without fretting over a drained battery. Four 10″ x 4 1/4″ solar panels woven into the umbrella’s 9′ diameter canopy convert sunlight into electricity which is accessed via two USB ports in its pole. A rechargeable 3.7-volt/1000mA backup battery provides power in overcast conditions, ensuring smartphones and tablets have an uninterrupted supply of power.”
