This has totally happened to me minutes ago.
So, I have an iPad mini air 2 in which was bought 2 years ago. I’ve had a terrible experience when I first got it. A charger cable plug was stuck on my charge plug so I had needed help. Its been affecting my chargers. 4 broken chargers every single month, maybe even year.
This time, my Charger cable broke and won’t totally charge so I tried charging it with my charger cable that was bought 7 months ago. I noticed as I plugged the head, the wire started having little sparks of light in the end of the small plug.
So I un-plugged it, making sure it wasn’t electric. I checked again, I moved the wire a little, there it was again. I kept doing it and small fire just started to melt over and smoke was starting to come out.
I was freaking out. Like, totally freaking out.
This has scared me of leaving my charger plugged when I’m out somewhere. Glad it wasnt only me who experienced such small event. It’s dangerous and it could cause fire to your house.
