My old iPhone charger over heated and my new one is not charging properly. What should I do?

Is the battery broken? Is the phone broken? Is there just a cooling delay before it charges again? Is the power chord broken?

So I changed cell phone chargers and am now using apple and it’s charging normally again, I was told non apple chargers are usually not good with apple devices.
