Solar-powered Spaza Kiosks allow for extended hour trading, which means more feet through the door after working hours. The average African citizen spends $2 per week on cellphone charging. By promoting free solar-powered charging at your kiosk, that $2 can be spent at the kiosk on other items.
Window Socket: Designed by Kyuho Song & Boa Oh, the portable socket plugs to a window and draws solar power to an internal battery, which enables one to either plug in small devices to the outlet right there and then, or save the stored power for use during night time hours. via designtrend #Solar_Power_Battery
