Apple has filed a federal lawsuit against a New Jersey company over what Apple says are counterfeit chargers and cables for its products that were sold on Amazon, according to AP

Apple claims the company, MobileStar, printed Apple logos on products that that “pose a significant risk of overheating, fire, and electrical shock.” The chargers and cables are being represented on Amazon as genuine Apple products.

Apple says it purchased the products on Amazon and later told the online retailer that they were fake. Amazon then identified Mobile Star as the source.

Amazon isn’t named in the suit.
