Travel adapter from Mexico to Tonga

⚠️

Adapter Required

Yes — coming from Mexico, you will need a travel adapter for Tonga. Mexico uses Type A/Type B plugs, and Tonga uses Type I, so the pin shapes will not fit any wall socket. Voltages differ (127 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.
