Bought a D2-912 aka D2-PAD Internet Tablet at Big Lots. It came with a charger and in the instructions say to only use that charger. Had it one week and yesterday 5-11-13, I was moving some flv and MPG4 files from my computer to the plug in Micro SD card and I noticed that the USB charged it while it was plugged in. So, I left it plugged in after I was done and the battery came to full 100% charge. THAT might come in useful to anyone that has one of these and has it away from home and don't have the actual charger with them. I was wondering if I can use a cigarette lighter adapter -> Micro USB in the car? That would be very handy as one is driving to keep the tablet up to charge. Also I downloaded Google Maps for this thing and it works beautifully! This is a Wi-Fi only tablet meaning you can't be driving along and pull off the shoulder and expect to use Google Maps, but rather find a local wi-fi hot spot, such as Pizza Hut, McDonalds, etc and maybe even some rest stops??? to get a wi-fi signal.
