Charging cord manufactured by Bose nearly caused a fire in our home! Everyone smelled the smoke and an electric charge was in the air, but we couldn’t find the source immediately. Then my son saw the smoke. it was the charging cord for a mini Bose speaker that we’ve had less than one year. It burned a black mark in the wood desk it was on, and the cord end is melted. If we had not been at home, I guarantee it would have started a fire in our home.
