Travel adapter from Taiwan to Oman
Adapter Required
Yes — coming from Taiwan, you will need a travel adapter for Oman. Taiwan uses Type A/Type B plugs, and Oman uses Type G, so the pin shapes will not fit any wall socket. Voltages differ (110 V at home vs 230 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.
