Travel Adapter for Tonga: Do You Need One? (Samoa → Tonga)No Adapter Needed

If you're heading to Tonga from Samoa, sorting out the power situation is one of the easiest pre-trip wins. Below you'll find the plug types, voltage, and frequency used in Tonga, whether you need an adapter, and which devices are safe to plug in.

Do you need a travel adapter for Tonga?

Good news: you generally don't need a plug adapter. Both Samoa and Tonga use Type I outlets, so your existing plugs should fit Tonga's sockets directly. A universal adapter is still worth keeping in your bag as a backup for future trips.

What plugs and sockets does Tonga use?

Tonga uses the following power plug: Type I: two flat angled pins (plus ground), used in Australia, New Zealand and China. Outlets run at 240V and 50Hz. Since Samoa also uses Type I, your plugs already match.

Voltage and frequency in Tonga

Tonga runs on 240V at 50Hz, very close to Samoa (230V, 50Hz). That means voltage isn't a concern here, since your appliances won't be over- or under-powered, so no voltage converter is needed.

Will your devices work in Tonga?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Tonga with just your existing plug, and no converter is required. Even heat-based appliances like hair dryers and straighteners should run fine given the matching 240V supply, though it's always worth a quick label check.

What travel adapter should you buy for Tonga?

Because Samoa and Tonga share Type I outlets, you don't need a special adapter for this trip. A universal travel adapter is still a smart, inexpensive backup if you plan to travel elsewhere, and the better ones add USB-C fast charging to free up your charger.

Tips for charging your devices in Tonga

Pack at least one adapter per traveler, and consider a small power strip from home, which turns a single Tonga outlet into several. Ordering online before you fly is almost always cheaper than airport kiosks.
