Timor-Leste to Tonga: Complete Plug & Adapter Guide (2026) Adapter Needed
Heading from Timor-Leste 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 Timor-Leste 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 close to Timor-Leste (220V, 50Hz), so your appliances should work without a converter.
When packing for Tonga, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
