Apple says 90% of all Apple charging accessories sold on Amazon are fake
Apple purchased these devices itself, and then informed Amazon that they were not legitimate Apple products. At that point, Amazon told Apple that a firm called Mobile Star was offering the counterfeit goods. These fakes present a health risk to consumers according to Apple, because they "pose a significant risk of overheating, fire, and electrical shock."
Back in 2013, after a 23-year old woman was reportedly killed in China when she answered a call on her Apple iPhone 5, a number of incidents took place where iPhone and iPad users were getting shocked. Apple tied the problem to the use of cheap, third party chargers. The company started a campaign to exchange those poorly made chargers and cables for genuine Apple manufactured charging accessories. Apple is concerned that a number of its customers could again be facing danger after purchasing the knock-offs that were sold on Amazon.
If you purchased what was labeled as "genuine" Apple charging accessories from Amazon, we suggest that you call the online retailer or Apple.
