Have you purchased chargers for your Apple products from a third party?
Recent reports have suggested that some counterfeit and third party adapters may not be designed properly and could result in safety issues. Because of this, Apple recently announced a USB Power Adapter Takeback Program.
Starting August 16, 2013, if you have concerns about any of your USB power adapters, you can drop them off at an Apple Retail Store or at an Apple Authorized Service Provider. They'll ensure that these adapters are disposed of in an environmentally friendly way.
In exchange, for a limited time, you can purchase one Apple USB power adapter to charge your iPhone, iPad, or iPod at a special price — $10 USD. To qualify, you must turn in at least one USB power adapter and bring your iPhone, iPad, or iPod to an Apple Retail Store or participating Apple Authorized Service Provider for serial number validation. The special pricing on Apple USB power adapters is limited to one adapter for each iPhone, iPad, and iPod you own and is valid until October 18, 2013.
