Hey guy's a lot of people have had slow charging N7's so I thought I'd share. I just took mine apart & inspected the usb's ribbon cable - it seems to have worked loose so I reattached it & now my tablet charges again I went through hell to finally figure this out & hope it helps someone out there.
I also made a quick youtube vid just search nexus 7 won't charge & you should find it.
