It depends on the charger, and how far gone it is. Take a sewing needle and push up the inside pins of the charger I believe there are 5-6. Push them up gently and plug in charger to see if it works. If all else fails go on amazon and buy a 10$ charger and toss the one that is giving you grief. Really think about it.. What's more expensive, a charger, or a new charge port for your phone?
