blackX indicator when i plug my Galaxy s3 into charger, what does that mean?

[AC Question]

blackX indicator when i plug my Galaxy s3 into verizon car charger, what does that mean? when i plug in the home charger i get a black lightning indicator. I just got a new system upgrade but the car charger issue happened before the upgrade. I am thinking the car charger is bad, it has a loose fit when i plug it in. They are not cheap to replace and it is quite new.

Welcome to Android Central, and sorry for the wait. It probably means there is insufficient current to charge.
