Compare the plug shapes, voltage and frequency in Palau and Tonga, and find out which adapter you need before you travel.

Adapter required

Yes — coming from Palau, you will need a travel adapter for Tonga. Palau uses Type A/Type B plugs, and Tonga 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.

Voltage converter may be needed. Check your device label — most modern electronics (phones, laptops) support 100–240 V and only need a plug adapter. Hair dryers, kettles, and older appliances may need a step-up or step-down converter.

Frequency differs (60 Hz vs 50 Hz). Rarely an issue for most electronics, but can affect motor-driven devices like clocks and shavers.
