In the Marshall Islands, they use Type A and B plugs and sockets. The mains voltage is 120 V, and the frequency is 60 Hz.
So, you’ll definitely need a travel adaptor in the Marshall Islands. Their plugs and sockets aren’t the same as our Type G back in the UK.

These details combine official input from electricity authorities, IEC standards, and practical experience from people who’ve travelled internationally.
Sockets in the Marshall Islands
the Marshall Islands uses Type A and B plugs and sockets.
Type A

Type A sockets have two flat parallel pins and no grounding. Unlike Type G, they don’t include an earth pin, which makes them less secure.
Type B

Type B sockets have two flat parallel pins plus a round grounding pin. Unlike Type G, the pins are thinner and there’s no built-in fuse.

No adaptor once you’ve landed? Airports and local shops are an option. But nothing beats the peace of mind of having your own ready to use.
The Marshall Islands are often visited together with Micronesia and Palau. It’s a good idea to look at those pages as well — plugs and voltage can vary between islands.
Do You Need a Voltage Converter?
You might run into problems plugging straight in the Northern Mariana Islands, as the voltage isn’t the same as the UK’s 230 V. A converter will sort that.
Before you plug in abroad, make sure to check the voltage label. Devices marked ‘100–240 V, 50/60 Hz’ can handle different voltages, so no converter needed.
