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

Getting ready for your journey from Tonga to South Sudan? 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.

Tonga uses Type I plugs, while South Sudan uses Type C and D. 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 South Sudan (230V, 50Hz) are close to Tonga (240V, 50Hz), so your appliances should work without a converter.

Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
