Introducing the Window Socket, a solar charger that adheres to windows with suction and acts like an electrical socket converting energy from the Sun. Its inventors are Kyuho Song and Boa Oh, two industrial designers. Each Window Socket contains a 1,000 milliamp- hour battery, equivalent to the battery in your smartphone. The built-in battery takes 5 to 8 hours to fully charge and stays charged for up to 10 hours.
Window Socket can be used anywhere there is exposure to sunlight – while sitting at the window seat on board an airplane, or adhered to a car window, or anywhere outdoors. Shaped like a disc it can adhere to almost any transparent glass surface. With a built-in converter it provides electricity to any device plugged into it. The plug outlets shown in the picture are those used in Japan. So if you are here in North America and want to get one you will need a plug converter.
For road warriors and those off the power grid, Window Socket is a great tool for powering up small electronic devices. Right now it appears to be a prototype and no price is mentioned as of yet.
