Query: Five Star Fire Hazard

Worked fine for the first two uses. Today, it is going to the landfill along with the rest of the garbage. Although the metal prongs were making contact with the outlet, the charger would only charge while holding the charger against the outlet in a certain way. After a few attempts, the charger was working again, without human intervention.Just when I was comfortable that it was working, there was a bright flash and a puff of smoke.Zero stars as a chargerFive stars as a fire hazard.
