[Q] car charging for sm-t210 topic

hi, does anyone have a solution. when i plug my note 3 7" in it doesn't even register as being plugged in. do other roms correct this problem? or is there another solution. I've tried different plugs with outputs that say they are the same as the wall outlets (which charges fine)

This is a major problem as i only got this tablet to replace my car stereo. I have everything done and wired up, but now I have a tablet that can't charge while in the car.

Any solution and I would be very grateful. thanks.
