Tonga to Saint Vincent and the Grenadines: Complete Plug & Adapter Guide (2026) Adapter Needed

Heading from Tonga to Saint Vincent and the Grenadines? 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.

Tonga uses Type I plugs, while Saint Vincent and the Grenadines uses Type A and B and G. 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 Saint Vincent and the Grenadines (230V, 50Hz) are close to Tonga (240V, 50Hz), so your appliances should work without a converter.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Saint Vincent and the Grenadines specifically, look for one that supports Type A/B/G outlets. USB charging ports built into the adapter are a nice bonus.
