What is the Voltage and Frequency in Tonga?

The electrical current in Tonga is 240 volts with 50 cycles per second. So the main information you will need to know for using your own appliances in Tonga is that the electricity in Tonga runs on 240 volts 50Hz.

You will be able to use your electrical appliances in Tonga if the voltage where your electrical items were manufactured for is a country using 220-240 volts. These countries include the UK, Europe, Australia and most of Asia and Africa.

If you are from a country that has a different electrical range, such as 100-127 volts, and therefore your electrical items are manufactured to run on that system, you will need to get a converter or a transformer for using your appliances in Tonga. A voltage converter is a feature of many travel adapters, so be sure to look out for this specification if you need it. Countries in this category include most countries in North and South America.

Does Tonga Experience Power Cuts?

Tonga experiences planned and unplanned power cuts. Power cuts on Tongatapu are rarer than on some other islands like Vava’u, Ha’apai and ‘Eua. Planned power cuts by Tonga’s sole public power administrator, Tonga Power, usually last around seven hours throughout the day, while unplanned power cuts are often resolved quickly.

Some more remote accommodations in Tonga use their own power generators, which may cut out more frequently than what’s connected to the national grid.

The most common time for power cuts to occur is during the wet season where tropical storms are more frequent and can cause damage to power lines, power stations, etc. The wet season in Tonga runs from December to April.
