I was using this car charger to charge my MacBook Pro from past two months without any issue in my Swift Dzire 2012 model. Today, I connected two laptops at the same time using a multi socket extension. It worked fine for 15 minutes and then cigarette lighter fuse blown.
I took car to service centre and they replaced the blown fuse with another one of same capacity (15 AMP). When I again plugged in the charger into cigarette lighter socket then it blown again in few seconds. This happened a couple of times.
Finally, they used another car charger which looked like this and this time fuse was not blown.
Is it possible that the charger that I am using is the culprit and blowing up fuse repetitively? And is there anything that I can do to test and fix it?
Note - I was using this charger from two months without any issue but with a single laptop.
