Travel adapter from Samoa to Marshall Islands
Adapter Required
Yes — coming from Samoa, you will need a travel adapter for Marshall Islands. Samoa uses Type I plugs, and Marshall Islands uses Type A/Type B, so the pin shapes will not fit any wall socket. Voltages differ (230 V at home vs 120 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not. The mains frequency is also different (50 Hz vs 60 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
