Apple just launched a exchange program in 36 countries for certain models its 5W USB power adapter, which the company has reported can overheat and pose a security risk, in some cases, at no cost to the customer. Apple recommends all users who have this A1300 charger model to change it as soon as possible for the A1400, a charger that the iPhone 5 uses.
This particular adapter, It is the one that came with the iPhone 3GS, iPhone 4 and iPhone 4s models, which were distributed between October 2009 and September 2012, when the iPhone 5 was launched. This charger was also on sale independently for those users who needed a replacement as a second charger or because it had broken down.
To identify the charger model we have, the first thing is to get hold of a magnifying glass. In the image that heads the article we can see perfectly where the model is indicated, but in reality, you have to have a very good eye and pay enough attention to be able to read it clearly. If you have the A1300 model and the CE letters in dark color, go looking for a space in your agenda to visit an Apple store and proceed to change it for the A1400 model that has the CE letters in white.
If unfortunately, as is my case, you do not have an App Store in your area, you can approach an authorized Apple reseller. If you also do not have an authorized dealer in your area, very likely, you can approach from next week a telephone store of the provider with which you obtained your iPhone, where they will check the serial number of our iPhone to make sure that model it has been provided by that company.
