Apple has announced an exchange program for its 5W European USB power adapters that “may overheat and pose a safety risk.” The affected adapters came with the iPhone 3GS, iPhone 4, and iPhone 4S models shipped from October 2009 to September 2012 in a number of European countries — the full list is included within the announcement. Though the adapters only pose a risk “in rare cases,” the company is voluntarily offering a free, new, redesigned power adapter for each affected adapter exchanged. Affected models are marked “Model A1300” with the letters “CE” in solid gray.
Apple recommends users with these adapters discontinue use and exchange the adapter. In the meantime, users can charge their iPhones by connecting the USB cable to a computer. Users must bring their affected adapters to an Apple Retail Store or participating Apple Authorized Service Provider to make the exchange for a new adapter.
