Tonga to Antigua and Barbuda: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Tonga to Antigua and Barbuda? 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 Antigua and Barbuda uses Type A and B. 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 Antigua and Barbuda (230V, 60Hz) are close to Tonga (240V, 50Hz), so your appliances should work without a converter.

Most modern phone chargers, laptop adapters, and camera chargers are designed to handle 100-240V input, so they'll work anywhere with just a plug adapter. Heat-producing appliances like hair dryers and flat irons are often single-voltage, so check before you plug them in abroad.
