@jessicasherlock , sherlock.jessicalyn, This is not really a cheap phone, I recommend you look in the charge port and blow/pick out(carefully) any dust/debri that may be causing an issue also look in the port for any bent pins and straighten very carefully with a tooth pick. Try a different compatible charger/cord again, to see if that is the issue. If different compatible charger/cord does not fix and port looks/test good, the battery or connection could be bad, if able to clean battery connections and reconnect/install battery, still not charging battery could be faulty(try another battery). If port is found to be bad/loose/damaged or signs of burnt/damaged components on the board, this is really not a repair for the inexperienced because the charge port for your device is soldered to the mother board and the heat generated could cause further damage if not very careful. I will post a link to a tear down guide to get you inside the tablet to check the charge port/battery connections and board. If not wanting to try the repair/diagnosing pop into a good local cell/computer repair shop and have them take a look, diagnose and estimate repair. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
