Apple has said that the USB adapters can overheat and pose a safety risk in "rare cases." Affected adapters can be identified on the bottom with the name "Model A1300" and the letters "CE" in solid gray.
"Customer safety is always Apple's top priority, and we have voluntarily decided to exchange every affected power adapter for a new, redesigned adapter, free of charge," the company said. "We encourage customers to exchange any affected adapter for a new one as soon as possible."
Affected adapters are identified as "Model A1300." The redesigned adapter, "Model A1400," does not need to be replaced.
Owners of affected adapters can bring them to an Apple Retail Store or a participating Apple Authorized Service Provider. They will need to have their iPhone serial number verified as part of the exchange process, so users must bring their iPhone with them.
Those who cannot bring their affected adapter to a location can contact Apple Technical Support and attempt to arrange an exchange. Users who own affected adapters are encouraged to charge their iPhone through their computer's USB port until the part is replaced.
The full list of countries where the adapter was sold is included below:
- Czech Republic
- South Africa
