Is it commonplace for Sony MiniDV HC28 camcorders' charger ports to stop working? - camcorder batteries charger it works!

I took something is connected to the charger, and I'm not sure what happened, but I hear a sort of crackling quickly and now when I plug something on port the camera. I bought a separate charger, but my port is always useful? Is this normal? Do you have any idea what might happen?
