Anyone else having charging issues? I got the one a couple months back with the larger on board memory and this one. Both have issues with charging. Neither will charge with the power "plug" supplied. The cable works fine, but will only charge with a generic wall charger that I found around the house. I have tried charging with the tablet off, on, in use, and not... Same result. The supplied plug won't work at all, the generic plug does, slowly. Other than that, I LOOOVE this tablet (obviously as I bought a second)
