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

Heading from Croatia 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.

Croatia uses Type C and F 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 Croatia (230V, 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 Tonga specifically, look for one that supports Type I outlets. USB charging ports built into the adapter are a nice bonus.
