I have a 1st Generation N7 that doesn't charge properly. I bought a new battery for it, which worked for awhile, but also stopped charging. Other than that, my N7 worked and looks great. I would love to get it back into service if possible. Is there such a thing as a stand alone charger that will charge the battery outside the device? If I could just pop a fully charged battery into it whenever necessary, I think it would work just fine.
