Papua New Guinea to Tonga: Complete Plug & Adapter Guide (2026) No Adapter Needed

Heading from Papua New Guinea to Tonga? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Both Papua New Guinea and Tonga use Type I plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

The voltage and frequency in Tonga (240V, 50Hz) are the same as Papua New Guinea (240V, 50Hz), so your appliances should work without a converter.

Don't forget that Tonga hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
