Imagine a portable socket that gets its power from the sun rather than the grid. It seems now you can charge your cellphone and gadgets no matter where you are and using solar power. It seems easy, you would just plug into a window instead of into the wall.
According to the designers, Kyohu Song and Boa Oh, that is the whole point, “We tried to design a portable socket, so that users can use it intuitively without special training,” they write.
It is really simple. The portable socket attaches to a window and takes solar power through solar panels on its underside:
The solar panels suck energy from the sun and the charger converts that energy into electricity. You plug in to the charger.
In addition, the charger stores that energy. After five to eight hours of charging, the socket provides 10 hours of use. You can pop it off the window, stick it in your bag, and use it to charge up your phone with solar energy, even if you’re sitting in a dark room.
