This solar phone charger is designed to be deployed at outdoor events like weddings and concerts so that people can charge their phones. Normally extension cords or large cumbersome solar umbrellas have to be set up to fill this need.
The one issue is that people have to supervise their charging and the charger itself can be stolen. In a future iteration I will add essentially a port for a bike lock and locking compartments for phones to sit in while charging.
I would also like to spread the usb ports around the edges more so that they are not so condensed. It will change the experience from waiting in line to just walking up and plugging into your own space.
