Starting Friday, Apple device users in China who have concerns about their USB power adapters can drop them off at any Apple retail store or authorized service provider and get an official Apple USB adapter for $10, about half the usual price.

The special pricing is limited to one adapter for each iPhone, iPad or iPod.

Apple announced the USB Power Adapter Takeback Program on Monday. The program will kick off in the United States on Aug 16 and run until Oct 18.
