The three-pronged plugs, primarily used in the UK, Hong Kong and Singapore, were sold with Mac computer and mobile devices between 2003 and 2010, as well as part of the Apple World Travel Adapter Kit.
“An affected three-prong plug adapter is white, with no letters on the inside slot where it attaches to the main Apple power adapter,” the company said in a blog post.
“Because customer safety is a top priority, Apple is asking customers to stop using affected plug adapters.”
Apple said it was aware of six incidents worldwide involving the plugs, but the recall did not affect its USB port-based adapters.
The technology giant confirmed it will exchange affected plugs for new adapters.
