Chosen Solution
It won’t charge anymore. I have tried other wires. My iPhone charges. So I know it’s the charging port.
I would suspect that the iPod’s battery is dead seeing as how this unit is probably 5 years old. iFixit doesn’t sell the battery but a quick Google search should point you in the right direction. I would follow this guide for the replacement. Keep in mind that the battery is soldered in place so it will require some soldering skills to complete the repair.
I read somewhere to look inside the charging port to see if it’s dirty. I poked in a toothpick, and a piece of lint came out. Problem solved!
