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

Whether it's a business trip or a vacation, traveling from Oman to Tonga requires a quick check on power compatibility. The last thing you want is to arrive and discover your charger doesn't fit the outlets.

The plug types are different between these two countries. In Oman, outlets accept Type G, but in Tonga you'll find Type I sockets. A travel plug adapter is essential for this trip.

On the voltage front, Oman (240V, 50Hz) and Tonga (240V, 50Hz) are identical. You shouldn't need a voltage converter for your electronics.

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.
