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

Getting ready for your journey from Serbia to Tonga? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

Your Serbia plugs (Type C, F) won't fit Tonga's outlets (Type I). You'll want to grab a universal travel adapter or one specifically designed for Tonga before you depart.

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