Apple has recalled AC wall plug adapters designed for Mac and certain iOS devices between 2003 and 2015 due to the risk of electrical shock if touched.

The chargers were sold in Europe, Australia, New Zealand, Korea, Argentina and Brazil. The tech giant is aware of 12 incidents worldwide of people getting zapped by the chargers.

The company said in a statement: “Because customer safety is the company’s top priority, Apple is asking customers to stop using affected plug adapters. Customers should visit www.apple.com/support/ac-wallplug-adapter for details about how to exchange the affected adapters for new, redesigned ones.

“An affected wall plug adapter has 4 or 5 characters or no characters on the inside slot… redesigned adapters have a 3-letter regional code in the slot (EUR, KOR, AUS, ARG or BRA)”.
