A lot of gadgets have let usual power sources aside and now use usb to charge/work. This can be a problem when you don`t have an usb source around, or when you look around your house and you see a lot of transformers so you can use usb ports.
Well, the piece I`m writing about helps you mitigate this problem a bit, by transforming normal electricity power into usb ports that can be used to charge whatever you want!
