Marshall Islands to Trinidad and Tobago: Complete Plug & Adapter Guide (2026) No Adapter Needed

Heading from Marshall Islands to Trinidad and Tobago? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Both Marshall Islands and Trinidad and Tobago use Type A/B plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

The voltage and frequency in Trinidad and Tobago (115V, 60Hz) are close to Marshall Islands (120V, 60Hz), so your appliances should work without a converter.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Trinidad and Tobago specifically, look for one that supports Type A/B outlets. USB charging ports built into the adapter are a nice bonus.
