Northern Mariana Islands Travel Adapters
Type A & Type B • 120 volts • 60 Hz
North Field on Tinian, one of the Northern Mariana Islands' three main islands, was the largest airfield in the world during World War II and the departure point for both atomic bombing missions: the Enola Gay took off from its runway on August 6, 1945 bound for Hiroshima, followed by Bockscar's mission to Nagasaki on August 9.
The Northern Mariana Islands are a United States Commonwealth in the western Pacific Ocean located north of Guam. The capital is Saipan. The islands are known for their beaches, World War II historical sites, and tropical climate.
The Northern Mariana Islands use mains electricity supplied at 120 volts at 60 Hz, the same standard as the US mainland. Wall outlets use Type A and Type B. Travelers from regions that use different plug types need a travel adapter for Type A or Type B; equipment that is not dual voltage requires an appropriate voltage converter.

Do I need a voltage converter for the Northern Mariana Islands?
Only if your device isn't dual voltage. Most phones, laptops, and cameras are rated for 100–240V and only need a plug adapter for the Northern Mariana Islands' outlets. High-wattage single-voltage appliances, like hair dryers, straighteners, or some CPAP machines, need a voltage converter, not just an adapter. Check the device label for its voltage rating before you travel.
Can I use my US phone charger in the Northern Mariana Islands?
Yes. The Northern Mariana Islands run on the same 120V, 60Hz supply as the US mainland, so a US phone or laptop charger plugs in and works directly with no adapter or converter needed.
Are the Northern Mariana Islands and US power outlets interchangeable?
Yes. The Northern Mariana Islands are a US commonwealth and use the same Type A and Type B outlets at the same 120V, 60Hz standard as the US mainland, so US plugs and chargers fit and work without any adapter.
Does the Northern Mariana Islands use more than one plug type?
Yes. Type A is an ungrounded plug with two flat parallel pins, and Type B is the same two flat pins plus a round grounding pin. Type A plugs fit directly into Type B sockets, so a Type B adapter covers both.
