Apple Inc. sued companies it said are selling unauthorized electronic accessories such as chargers, speakers and cables for the iPod music player, iPhone and iPad tablet computer. “Many are of inferior quality and reliability, raising significant concerns over compatibility with and damage to Apple’s products,” Apple said in the complaint, citing a user comment that a charger from one of the companies drained his iPod rather than replenishing the battery.
