Apple has issued a voluntary recall of AC wall adapters after becoming aware of a dozen cases where users received an electric shock.
The multinational company behind the iPad, iPhone and Mac PC launched an international AC Wall Plug Adapter Exchange Program on Friday after revealing problems with the adapters.
"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," the Cupertino, California, based company said in a media statement.
"In very rare cases, affected Apple two-prong wall plug adapters may break and create a risk of electrical shock if touched. Because customer safety is the company's top priority, Apple is asking customers to stop using affected plug adapters."
Apple said the wall plug adapters shipped with Apple Mac personal computers and some devices running iterations of Apple's iOS mobile device operating system between 2003 and 2015 were affected by the recall. Affected adapters were also included in the Apple World Travel Adapter Kit.
"Apple is aware of 12 incidents worldwide," the company said but did not elaborate on where they were or how badly hurt those affected by the malfunction were.
"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."
The company was quick to clarify that only users of adapters for some countries risked electric shocks.
"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 said.
Apple directed Mac and iOS device users to its website, apple.com/nz/support/ac-wallplug-adapter/, for more details on how to identify an affected adapter.
Adapters with flat angled blades need replacing in Argentina, Australia and New Zealand.
In continental Europe it's round thin pins, which are slightly slanted inward.
Adapters with round thick pins need replacing in Korea.
Round thin pins need replacing in Brazil.
Apple said, on its website, adapters could be exchanged at local Authorized Apple Service Providers such as Yoobee.
Apple Mac and iOS users can request a replacement via the website or contact Apple Support direct.
"We will need to verify your Mac, iPad, iPhone or iPod serial number as part of the exchange process so please find your serial number in advance," Apple said.
Finding your device serial number is easy. You'll find it under Settings>General>About>Serial Number. To take a screen shot of it on an iOS device hold the Home key down and press the Power button.
It's not the first time Apple has had to run such replacement programmes. In 2013 Apple said iPhone users answering their smart phone while it was plugged in to the mains using third-party or counterfeit mains chargers were at risk of electrocution.
Apple offered to replace third party mains charges with genuine Apple versions for US$10 after bride-to-be Ma Ailun suffered a fatal electric shock when she answered her charging iPhone 5 in July.
