Sounds like a bad charger issue, nothing to do with you Samsung Tab.

It will have to be a charger capable of 2.1 Amps, but not all chargers will work with the Samsung and not all cables will work with all chargers! It may take a little trial and error to get the right combination! OEM Samsung chargers are available on Ebay and Amazon for less than $10 and seem to always work best for me! Look for the lightening bolt in the battery icon when charging!

When you have to wiggle in order to charge, either you have bad USB cable or USB charging port. Try known working USB cable first.
Tab 3 has different models and sizes, I have no idea which one you have.
Tab 3 7.0 , the micro USB port in on mainboard, you need solder skill or asking a repair shop to replace it.
Tab 3 8.0 or larger, USB port is on flex cable, this one is easy to replace and cost under $10.

Use this tool to help you to see which one is the problem: charger, USB cable, or USB port. Current should be at least 1.5 Amperes if everything is working. No guessing as you see your tablet is charging or not when swapping part one by one until the problem solved: charger, USB cable, USB charging port .
The charger must have an output of 5V, 2 Amps , read the small print on the side of your charger.
