I have a similar problem with the Galaxy Tab 1. It means the charger is faulty and won't charge the tablet (or will charge it very slowly - which seems to be your case). Try squiggling it around a little bit until it charge, also consider buying a new Samsung tablet charger (the phone charger has a lower output, which is inadequate for a tablet), don't use the knock-off brands!.
If the red X is there even when it's not charging, then the battery is faulty, take it to the service center.
The problem is that your tablet needs to recognize your charger as a charger that can provide 2A. But only a Samsung charger will provide the right signal. Any other USB power source will limited to 0.5A. The result is that you need to get an original charger from Samsung.
