Units can potentially overheat
Apple has announced a free program to replace what it says are potentially dangerous European 5W USB power adapters. The adapters are identifiable by an "A1300" model number, and the letters "CE" displayed in solid, dark gray. They were available between October 2009 and September 2012, and bundled with the iPhone 3GS, 4, and 4S, as well as sold separately.
In its warning, Apple explains that the bad adapters can potentially overheat and cause damage in "rare cases." In exchange Apple is offering a redesigned model, the A1400. To swap for a new unit a person must bring an A1300 to an Apple Store or an authorized service provider, and where applicable bring in the associated iPhone so that the serial number can be checked. Should there not be a location nearby, a person can still call Apple technical support and attempt to organize an exchange that way.
Despite being oriented towards continental Europe, the A1300 was also distributed in a number of non-European countries. These include Egypt, India, Indonesia, Israel, Russia, South Africa, and Vietnam.
