Apple is warning that some users of its 5W European USB power adapter  - the one that shipped with the iPhone 3GS, iPhone 4, and iPhone 4S between October 2009 and September 2012 – should swap the charger for a new one as the existing unit “may overheat and pose a safety risk”.

The replacement scheme for affected chargers announced today and spotted by 9to5Mac will, of course, see all potentially affected adapters replaced free of charge. Apple notes that other 5W USB power adapters are not included in this scheme.

The affected adapter is the A1300 model, which have the letters CE in solid gray. The new adapter, which isn’t affected, is an A1400 model and has the letters CE outlined in gray.
