The ProMaster Apple Travel Adapter is for use with most Apple laptop, tablet, and phone power supplies. The adapter replaces the standard wall outlet prongs on your Apple charger. It provides a variety of adaptable prongs allowing you to configure it for use in over 150 countries! While the adapter provides the connection to various wall AC receptacles, it does not convert voltage. Most Apple chargers can handle an input voltage that is compatible throughout the world. However, be sure to double check your charger's input as compared to the outlet voltage you intend to use.
