Marshall Islands Power Plugs, Wall Sockets & Electrical Outlets
In Marshall Islands, power plugs and sockets (electrical outlets) of Type A (NEMA 1-15, two flat parallel pins, ungrounded) and Type B (NEMA 5-15, two flat parallel pins plus round grounding pin, grounded) are used. Wall sockets run at 120V and 60Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Marshall Islands.

Power Sockets and Plug Types in Marshall Islands
The Marshall Islands power plug standard follows the North American system, with both Type A and Type B plugs in common use across the country. Electricity is supplied at 120V and 60Hz, matching the specifications used throughout the United States, which is unsurprising given the islands' historical and political ties to the U.S. Type A is the two-pin ungrounded plug found on smaller electronics, lamps, and phone chargers, while Type B adds a third round grounding pin for larger appliances, computers, and power tools that require additional safety protection.
Both plug types are widely installed in hotels, homes, and businesses throughout the Marshall Islands. Because Type B outlets are backward compatible, a standard plug top with two flat pins will fit into either a Type A or Type B socket, though the reverse is not true for grounded three-pin devices.
Do All Sockets in Marshall Islands Look the Same?
Not every electrical outlet in the Marshall Islands looks identical, since both two-pin Type A and three-pin Type B sockets are in circulation. Newer buildings and modern installations tend to favor the grounded Type B outlet for improved safety, while older properties may still only offer the ungrounded Type A version. Travelers should check the shape of their device's plug against the socket before assuming compatibility, particularly with grounded electronics.
Do You Need a Travel Adaptor for Marshall Islands?
If your home country already uses Type A or Type B plugs and a 120V/60Hz supply, such as the United States, Canada, or parts of Central America, you will not need a travel adaptor for the Marshall Islands. Visitors from countries using different plug shapes or running on 220-240V systems, however, will need an adaptor to physically fit their devices into local sockets, and possibly a voltage converter for equipment that isn't dual-voltage.
Where to Buy a Travel Adapter for Marshall Islands
Travel adapters for Type A and Type B outlets are widely available before departure at airport shops, electronics retailers, and online marketplaces, and it's generally easier to purchase one in advance rather than searching for the right style once you arrive in the Marshall Islands. Look specifically for adapters labeled for North American or US-style plugs, since these correspond exactly to the sockets used throughout the islands.
Frequently Asked Questions
You only need a travel adaptor if your devices use a plug shape other than Type A or Type B. Since the Marshall Islands uses the same 120V, 60Hz system and plug types as North America, travelers from those regions can use their existing plugs without any adapter.
Some are and some aren't. The Marshall Islands uses both ungrounded Type A sockets and grounded Type B sockets, with Type B featuring a third round pin for grounding protection on larger appliances and electronics.
Yes, most modern phone chargers are dual-voltage and can handle the Marshall Islands' 120V, 60Hz supply without a converter. You'll simply need a plug that matches the local Type A or Type B outlet, which is standard for devices from North America.
Pack a Type A or Type B plug adapter if your devices use a different plug shape, along with a voltage converter if your equipment isn't rated for 120V. Travelers from the US, Canada, or similar regions can typically bring their devices as-is since the plug types and voltage already match.
