Compare the plug shapes, voltage and frequency in Honduras and Nauru, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Honduras, you will need a travel adapter for Nauru. Honduras uses Type A/Type B plugs, and Nauru uses Type I, so the pin shapes will not fit any wall socket. Voltages differ (120 V at home vs 240 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 (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
