7: The XD Design Solar Window Charger
Nothing is more frustrating than trying to charge your phone and you don’t have a cable. Or the battery to your car dies, and you are stuck with no way to charge your phone. There’s a solution for that, and it is the XD Design Solar Window Charger. Just attach to a window in your car, and you have a quick charging solution (via McCarthy Auto Group).

Solar power is everywhere, so it makes sense to use one to charge your phone. The installation isn’t that difficult, and the results are surprisingly better than you’d expect for the price.
