Tanzania to Tonga: Complete Plug & Adapter Guide (2026) Adapter Needed

Heading from Tanzania 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.

Tanzania uses Type D and G plugs, while Tonga uses Type I. Since there is no overlap, you will need a travel adapter to plug in your devices. Make sure to pick one up before your trip or at the airport.

The voltage and frequency in Tonga (240V, 50Hz) are close to Tanzania (230V, 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.
