Marshall Islands to Sierra Leone: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Marshall Islands to Sierra Leone? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

Marshall Islands uses Type A and B plugs, while Sierra Leone uses Type D and G. Since there is no overlap, you will need a travel adapter to plug in your devices. Make sure to pick one up before your trip or at the airport.

Be aware that Marshall Islands runs on 120V at 60Hz, while Sierra Leone uses 230V at 50Hz. This voltage difference matters for appliances like hair dryers, curling irons, and electric shavers that aren't dual-voltage. Check the label on your devices. If it says "100-240V," you're fine. Otherwise, you'll need a voltage converter.

When packing for Sierra Leone, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
