On August 6th, Apple announced it would initiate a USB Power Adapter Takeback Program in response to safety issues with some counterfeit USB power adapters for iOS devices. The program will allow users to buy an Apple USB power adapter for only US$10 if they trade in one of their counterfeit units.
The program was originally only available in the US and China. However, just six days later Apple expanded the program to customers in Japan, Canada, Australia, France, Germany, and the United Kingdom.
And now today Apple has expanded the program on a global scale, offering the Takeback program for customers in Austria, Belgium, Czech Republic, Denmark, Finland, Hong Kong, Hungary, Ireland, Italy, Korea, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Spain, Sweden, Switzerland,and Taiwan.
