My iphone charger got short ciruited because of the iphone cable which got it's outer covering ripped off already. The charger still works. But my question is, is it still safe to use? On the cable, there isnt any sign of damage to the wirings. (I removed a bit of the wire mesh because it also burned) As for other things, the fuse on the extension cord blew up and the circuit breaker for my room tripped. Another thing, the part that got short-circuited is the AC prongs.
