The company says in rare cases, the adapters can break and "create a risk of electrical shock if touched." The plugs in question were shipped from 2003 to 2015.
In a statement, Apple said it knows of 12 such incidents.
The voluntary recall applies to Argentina, Australia, Brazil, continental Europe, New Zealand and South Korea. It also applies to an adapter in the Apple World Travel Adapter Kit.
If your adapter is affected by the recall, Apple says you can exchange it or contact the company for a refund if you already bought a replacement.
