Wireless Charging for Nokia Lumia Free 3D model

this device has perfect performance . when you are in home or office you can use Usb(in) to put in plug and charge mobile . But what happen in out ? when you are in road or .... that you don't have any electrical.No problem ... you can open solar panel and use sun to charge it.or close panel and put it in your pack and move easily .what happen about old version of lumia that didn't charge with wireless ... you can use usb (out) and charge it( one way to plug and other way to mobile )
