Forgotten your adaptor and already abroad? Don’t worry — airports and local shops usually stock them. That said, packing your own saves you from high prices and poor quality.

Tonga is often combined with visits to Fiji and Samoa. Even nearby islands can have different plug types, so it’s smart to check before you travel.

The plug types you’ll find in Tonga are Type I plugs and sockets.

Type I sockets have two flat angled pins and sometimes a vertical earth pin. UK Type G plugs do not fit into Type I sockets.

Do You Need a Voltage Converter?

Converters only matter when voltages clash. In Tonga the supply is pretty much the same as the UK’s, so you’re sorted.

Before charging abroad, glance at the mains label: ‘100–240 V, 50/60 Hz’ confirms it’ll run safely without a converter.
