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

Getting ready for your journey from Oman to Marshall Islands? 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.

Your Oman plugs (Type G) won't fit Marshall Islands's outlets (Type A, B). You'll want to grab a universal travel adapter or one specifically designed for Marshall Islands before you depart.

Be aware that Oman runs on 240V at 50Hz, while Marshall Islands uses 120V at 60Hz. 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.

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