Apple has asked customers to stop using some plug adapters because of a risk of electric shock.

They are recalling two types of plug:

• The AC wall plug shipped with Macs and some iOS devices between 2003 and 2010.
• A three-pronged plug included in the World Travel Adapter kit.

The affected plugs are all white, with no letters or words on the inside slot.

Unaffected versions of the plug are white with a grey on the inside, with a dimple on the side.

Apple USB power adapters are not affected.
