I just got the tab 2 7.0 a few days ago and I have noticed the galaxy tab 2 is very picky as to what chargers it will actually charge through so I want to know what sort of car chargers will work with it. I plan on using my tab on long car trips but I want to be able to actually charge it. I have a car charger for other devices that is just a usb port that plugs into the 12 v outlet but I don't know if it will work. So I guess my question is what are the requirements for a charger to actually charge the tab 2 7.0. I currently can't test the one I have as I don't have access to a car until christmas when I have to make the long trip back home.
