Ascension Island Power Plugs, Wall Sockets & Electrical Outlets
In Ascension Island, power plugs and sockets (electrical outlets) of Type G (BS 1363, three rectangular pins in triangular pattern, grounded) are used. Wall sockets run at 240V and 60Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Ascension Island.

Do You Need a Travel Adaptor for Ascension Island?
If you're travelling from a country that doesn't use the British-style plug, you will need a travel adaptor for Ascension Island. The Ascension Island power plug follows the Type G standard, the same three-pin design used throughout the United Kingdom, so visitors arriving with two-pin or other plug shapes will need to convert their AC power plugs and sockets to fit local outlets. Packing a compatible adaptor before you arrive is recommended, since specialist electrical adaptors may be difficult to find on the island itself.
Voltage and Frequency in Ascension Island
Ascension Island runs on a 240V supply at 60Hz. This voltage is broadly in line with what's used across the UK and much of Europe, though the 60Hz frequency differs from the 50Hz standard found in Britain itself. Travellers from regions using similar voltage levels generally won't need a voltage converter, but it's worth checking device compatibility, particularly for anything sensitive to frequency changes such as certain clocks or motorised appliances.
Dual-Voltage Devices and Ascension Island
Most modern electronics, including phone chargers, laptop power supplies, and camera battery chargers, are dual-voltage and designed to accept a range of input voltages automatically. For these devices, a simple travel adaptor to physically fit the Type G socket is all that's required, with no separate voltage conversion needed. Always check the small print on your charger or power adapter, which typically lists an input range such as 100-240V, before plugging in.
Power Sockets and Plug Types in Ascension Island
Ascension Island uses the Type G plug, the familiar British 3-pin plug built to the BS 1363 standard. It features three rectangular pins arranged in a triangular pattern, with live and neutral pins measuring 6.35 by 3.18mm and a longer earth pin measuring 3.18 by 7.92mm. This grounded plug is rated for 13A at 220-240V and includes an internal cartridge fuse for individual appliance protection, one of the reasons it's regarded as an especially safe design.
The earth pin on a Type G plug also acts as a safety key, pushing open shutters inside the socket before the live and neutral pins can make contact. This sequencing means the earth connection is always established first and disconnected last. Because the plug is relatively large, it can sometimes crowd out neighbouring sockets on a power strip, so travellers using multiple devices should plan accordingly.
- Plug type: Type G (BS 1363), three rectangular pins in a triangular layout
- Voltage: 240V
- Frequency: 60Hz
- Rated current: 13A, with internal fuse protection (typically 3A or 13A)
- Grounded design with protective socket shutters
Frequently Asked Questions
Yes, unless your home country already uses the Type G plug. Ascension Island runs exclusively on the British-style Type G socket, so a travel adaptor is needed to connect plugs with a different pin configuration.
Ascension Island uses a 240V electrical supply at 60Hz. This is similar to voltage levels used in the UK, though the frequency differs from Britain's standard 50Hz.
Most phone chargers are dual-voltage and can handle 240V without any issue, so a voltage converter typically isn't necessary. You'll just need a travel adaptor with a 3-pin plug to physically fit the Type G sockets used on the island.
Ascension Island uses the Type G plug, the same three-pin design used in the United Kingdom. It's a grounded, 13A plug with an internal fuse and rectangular pins arranged in a triangular pattern.
