About two weeks ago, while plugging in the charger into a 120 volt receptacle, for some reason, a bright electrical spark happened which caused a blackout in my hotel room. It appeared that a breaker had to be reset. The adapter seems to working although there is a black flash spot on only one of the prongs towards the backend, the other prong was sparkling clean. Don't know what really happened but I'm lucky I came out of it unhurt. I do notice that I was generating static electricity while staying in that hotel room. Climate was cold and dry. Wonder at the time of the incident I was a ground to the hot side of the plug? That's not the case right or else I would have felt a shock. Vaguely recall the arc originating somewhere above the holes in the receptacle and terminating at one of the prongs in the charger. Strange. Anyway one experienced something similar? Again charger seemed okay.
