Guam Travel Adapters
Type A and Type B • 120 volts • 60 Hz
Guam is an island territory of the United States located in the western Pacific Ocean. It is the largest and southernmost of the Mariana Islands. The capital city is Hagatna. Guam has a strategic location in the Pacific and is known for its beaches, coral reefs, and Chamorro cultural heritage.
Guam uses mains electricity supplied at about 120 volts at 60 Hz. Wall outlets use Type A and Type B sockets, the same plug types used in the mainland United States. Travelers from regions that use different plug types should bring a compatible travel adapter. Visitors should confirm that their electronic devices support 100–240V input or use an appropriate voltage converter if necessary.

Plug types are listed because they are encountered in at least some installations. Presence may be partial, legacy, mixed, or situational. A travel adapter, also spelled travel adaptor, changes plug fit only; a voltage converter, sometimes searched as a voltage convertor, is needed only for devices that are not dual voltage. No plug type is excluded due to limited or declining use.
