Since then, concern has risen over using counterfeit and/or third party chargers for Apple devices. (It is important to note that not all third party adapters are an issue. Many are made to appropriate specifications and are just fine. But there are those “others”…)
In response, Apple has rolled out a “Takeback” program that will begin on August 16.
If you have concerns about your power adapter, you can take it (along with the device that it charges) to your local Apple store or participating Apple Service provider anytime between August 16 and October 18.
You will pay $10 for your new Apple adapter, which is half of the usual retail price. You can purchase one (and only one) for each device that you own.
You can read Apple’s official explanation of their program, and find a store near you by clicking here.
