Adapter required

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