Apple is recalling the two prong Apple AC wall plug adapters designed for use in Continental Europe, Australia, New Zealand, Korea, Argentina and Brazil, as they could break and create a risk of electrical shock if touched. These wall plug adapters shipped from 2003 to 2015 with Mac and certain iOS devices, and were also included in the Apple World Travel Adapter Kit.

Apple has received 12 reports of wall plug adapters breaking and consumers receiving shocks overseas, including three reports of consumers who were medically evaluated and released. No reports of incidents or injuries were reported by U.S. consumers.

The kits contain three-prong and two-prong AC wall plug adapters that fit different electrical outlets worldwide. The recalled adapters were made for use in Australia/New Zealand/Argentina, Brazil, Continental Europe and Korea and were also sold with Mac computers and iOS devices. The wall plug adapters are white plastic with the following characteristics:

• Australia/New Zealand/Argentina - flat angled blades
• Brazil - round thin pins
• Continental Europe - round thin pins, slightly slanted inward
• Korea - round thick pins

Recalled wall plug adapters have either four or five letters or numbers, or no markings on the inside slot where the wall plug adapter attaches to the main power adapter. Redesigned adapters have a three-letter regional code in the slot (EUR, ARG, KOR, AUS or BRA).

Apple will exchange affected wall plug adapters with a redesigned adapter, free of charge. In order to do that, you should provide Apple with the serail number of your Mac, iPad, iPhone or iPod.

You can then exchange your adapter(s) at your local Apple Store or an Authorized Apple Service Provider.

The affected units are about 814,000. About 81,000 of them were sold in Canada.
