Tristan da Cunha Travel Adapters
Type G • 230 volts • 50 Hz
Tristan da Cunha is widely considered the remotest permanently inhabited place on Earth. There's no airstrip, so the only way in or out is by boat, a six-day voyage from Cape Town that happens roughly ten times a year. Everyone on the island lives in a single settlement, Edinburgh of the Seven Seas, and the 2026 census counted just 221 residents.
Tristan da Cunha is a British Overseas Territory, administered together with Saint Helena and Ascension Island under the territory's full name, Saint Helena, Ascension and Tristan da Cunha. The main island is volcanic, centered on Queen Mary's Peak, and sits roughly 2,800 kilometers from Cape Town and about 2,430 kilometers from Saint Helena, its nearest neighbor. The wider archipelago also includes the uninhabited Inaccessible, Nightingale, and Gough Islands, with the latter two forming a UNESCO World Heritage Site.
Tristan da Cunha uses mains electricity supplied at 230 volts at 50 Hz. Wall outlets use Type G plugs, the same standard used throughout the United Kingdom. Travelers from regions that use different plug types should bring a compatible travel adapter. Visitors should confirm that their electronic devices support 100–240V input or use an appropriate voltage converter if necessary.

Do I need a voltage converter for Tristan da Cunha?
Only if your device isn't dual voltage. Most phones, laptops, and cameras are rated for 100–240V and only need a plug adapter for outlets on Tristan da Cunha. High-wattage single-voltage appliances, like hair dryers, straighteners, or some CPAP machines, need a voltage converter, not just an adapter. Check the device label for its voltage rating before you travel.
Can I use my US phone charger in Tristan da Cunha?
Most modern phone and laptop chargers are rated for 100–240V, so they work on the 230V supply used on Tristan da Cunha without a separate converter. You'll still need a plug adapter, since the charger's US plug won't physically fit the local outlets.
Are Tristan da Cunha and US power outlets interchangeable?
No. Tristan da Cunha uses Type G outlets and the US uses Type A/B. The plug shapes are different, and the local supply runs at 230V compared to 120V in the US, so a plug adapter alone is only safe for devices that already support both voltages.
Does Tristan da Cunha use more than one plug type?
No. Tristan da Cunha uses a single plug type, Type G, a grounded, rectangular three-pin plug that carries a 13-amp fuse in the plug itself. It's the same standard used throughout the United Kingdom, which administers the island.
