So I have a belkin charger for the car and a mce case on my iPhone. For some reason the official charger fits but the belkin doesn't. Is there anything I can do to make it fit?
It is not unusual for accessories like 3rd party chargers to not fit with other 3rd party accessories. You would need to either modify the case or charger connector. I would take the easy way out and get another OEM cable to use with this charger.
