Power Plugs in Tonga

Tonga uses Type I power plugs and electrical outlets. The standard voltage is 240V with a frequency of 50Hz. This is significantly higher than the 120V used in the United States and Canada, so travelers from North America should check their device compatibility.

Do You Need a Travel Adapter for Tonga?

Yes, travelers from the United States, Canada, Mexico, and other countries using Type A/B plugs will need a travel adapter for Tonga. The Type I outlets used in Tonga are not compatible with American plugs.

Voltage Converter vs. Plug Adapter

It's important to understand the difference: a plug adapter only changes the physical shape of your plug to fit Tonga's outlets, while a voltage converter actually changes the electrical current. Since Tonga uses 240V (higher than US 120V), you may need a voltage converter for older appliances like hair dryers. However, most modern electronics (smartphones, laptops, cameras) have built-in converters that work with 100-240V.

Tips for Travelers to Tonga

• Pack a Type I adapter before traveling - Tonga's outlets won't accept US plugs
• Tonga runs on 240V - check that your devices support this voltage or pack a converter for single-voltage appliances
• Traffic drives on the left in Tonga - look right first when crossing streets
• Stick to bottled or filtered water in Tonga - tap water isn't recommended for drinking
