Power Sockets and Plug Types in Tristan da Cunha
Tristan da Cunha power plug standards follow the British system, since the island is a UK overseas territory. The only plug type used here is Type G (BS 1363), the familiar three-pin design found throughout the United Kingdom and its former territories. If you're travelling from a country with a different plug shape, you'll need an adapter to connect your devices to the local electrical outlet.
Type G plugs feature three rectangular pins arranged in a triangular pattern: a longer earth pin at the top and two shorter pins for live and neutral below. This earth or grounding pin is more than just a third contact point, it acts as a safety key, pushing open the shutters inside the socket before the live and neutral pins can make contact. Each plug also contains an internal cartridge fuse, rated at either 3A or 13A depending on the appliance, giving an extra layer of protection that many other AC power plugs and sockets around the world lack.
Voltage and Frequency in Tristan da Cunha
The electrical supply on Tristan da Cunha runs at 240 volts and 50Hz, consistent with British and most European standards. This matters for travellers because devices designed for 110-120V regions, such as the United States and Canada, may not operate safely without a voltage converter. Most modern electronics like phone chargers, laptops, and camera batteries are dual-voltage and will handle 240V without any issue.
Understanding Tristan da Cunha's Power Plugs and Sockets
Because Type G is the sole plug standard on the island, packing the correct adapter is straightforward compared to countries that use multiple plug types. The design's triangular pin arrangement and protective shutters make it one of the safer choices worldwide, and its widespread use across former British territories means adapters are easy to find before you travel. Keep in mind that the plug's relatively large size can crowd power strips, so a single adapter per device is often more practical than trying to fit several into one multi-socket strip.
Where to Buy a Travel Adapter for Tristan da Cunha
Given the island's remote location with very limited local shopping options, it's best to purchase a Type G travel adapter before you depart. These are widely available at airport travel shops, electronics retailers, and online marketplaces, and are often sold as part of universal adapter kits. Look for an adapter that matches the BS 1363 pin dimensions and, if you're bringing higher-wattage appliances, confirm the adapter or plug fuse can handle the load.

- Large electronics retailers before you leave home
- Online marketplaces offering universal or UK-specific adapters
- Luggage and outdoor travel stores stocking adapter kits
Frequently Asked Questions
Yes, if your home country doesn't use Type G plugs, you'll need an adapter to fit the island's BS 1363 sockets. Since Tristan da Cunha only uses this one plug type, a single Type G adapter covers every outlet you'll encounter there.
Most phone chargers are dual-voltage and can handle Tristan da Cunha's 240V, 50Hz supply without a converter. You'll still need a Type G plug adapter to physically connect your charger to the local electrical outlet, but a voltage converter typically isn't necessary.
Tristan da Cunha uses 240 volts at 50Hz, matching British electrical standards. Travellers with devices built for 110-120V systems should check whether a voltage converter is needed, though most modern electronics are dual-voltage.
Pack a Type G travel adapter, since it's the only plug type used on the island, featuring three rectangular pins including a longer earth pin. If any of your devices aren't dual-voltage rated for 240V, also bring a voltage converter to use alongside your adapter.
