Tonga: plugs, voltage, currency, time & travel facts

Plugs and voltage

Tonga uses Type I sockets. Mains supply is 230 V at 50 Hz.

At 230 V, devices made only for 100–127 V (many American and Japanese hair dryers, curling irons and some shavers) will be damaged without a step-down converter. Chargers labelled “100–240V” work fine with just a plug adapter.
