Apple today announced a voluntary recall of AC wall plug adapters designed for use in Argentina, Australia, Brazil, Continental Europe, New Zealand and South Korea. Apple said that "in very rare cases," affected Apple two-prong wall plug adapters may break and create a risk of electrical shock if touched. These wall plug adapters shipped with Mac and certain iOS devices between 2003 and 2015 and were also included in the Apple World Travel Adapter Kit. Apple said it was aware of 12 incidents worldwide.

The recall does not affect any other Apple AC wall plug adapters designed for Canada, China, Hong Kong, Japan, United Kingdom, United States or any Apple USB power adapters.

Apple is asking customers to stop using affected plug adapters. Details about how to exchange the affected adapters for new, redesigned ones, are available at www.apple.com/support/ac-wallplug-adapter

An affected two-prong plug adapter has either four or five characters or no characters on the inside slot where it attaches to the main Apple power adapter.
