Ok, so I borrowed this Portable DVD player from my cousin, and I have no idea how to use it. So just a few stupid, obvious questions:

-When I plug it into the wall, do I need to turn it on for it to charge?
-And I know it says portable, but do I need a car plug for it?
-Does the red light mean it's charging?

I know the questions are up front, kind of obvious questions, but i'm just confused (I don't want you to think i'm stupid or anything...), and when I called my cousin, she wasn't much of a big help.

Thanks.
