3.Eton Rukus Portable Bluetooth Solar Powered Wireless Speaker System
A portable solar powered speaker system is a perfect gadget for summer picnics. Before this you’d have to listen to music through your phone’s speakers, which aren’t that good. Or you’d use one of those dock station speakers that will kill your phone’s battery in a matter of minutes.
That’s where this solar powered gadget will come in very handy. Not only can it play music and not drain your phone’s battery, you can actually charge your phone with it. The built in solar panels on this gadget produce enough energy to actually play music and charge your phone at the same time.
