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

Whether it's a business trip or a vacation, traveling from Antigua and Barbuda 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.

There's no plug compatibility between Antigua and Barbuda and Tonga. Antigua and Barbuda devices use Type A/B connectors, while Tonga sockets are Type I. An adapter is a must-have for this destination.

On the voltage front, Antigua and Barbuda (230V, 60Hz) and Tonga (240V, 50Hz) are very similar. You shouldn't need a voltage converter for your electronics.

Don't forget that Tonga hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
