I would like to introduce you one of the- conceptual solar charger that’s positively blown up around the inter webs over the past few days, which is no small feat in the over saturated sun-powered, gadget-charging market. And for what it lacks in power, the device makes up for with a clever and simple design that helps it truly stick out from the pack.
The creation of Korean designers Kyuho Song and Boa Oh, the window socket is a portable, suction plate-based solar converter-charger that functions as a standard (at this point, European) plug. Stick it on any window — at home, in the office, car windshield, commuter train — where there’s decent sunlight, and the device automatically starts converting sunlight into electric energy. Once fully charged – it takes about five to eight hours — remove the Window Socket and

you have yourself a handy-dandy little outlet-on-the-go that maintains its charge for an unfortunately short 10 hours.
Although you don't necessary have to remove the Window Socket to plug in, the device’s compact size makes it a shoo-in for outdoor excursions. However, with that 10-hour battery life, the window-to-wilderness timeframe is a bit tight.
