Sockets in the Solomon Islands
The plug types you’ll find in the Solomon Islands are Type G and I plugs and sockets.
Type G

Type G sockets have three rectangular pins arranged in a triangular pattern, with a built-in fuse for safety. They are the standard used in the United Kingdom.
Type I

Type I sockets have two flat angled pins and sometimes a vertical earth pin. UK Type G plugs do not fit into Type I sockets.

Forgotten your adaptor and already abroad? Don’t worry — airports and local shops usually stock them. That said, packing your own saves you from high prices and poor quality.
The Solomon Islands are usually visited together with Fiji and Vanuatu. Island nations often have their own standards, so it’s smart to check plug types before travelling.
Do You Need a Voltage Converter?
A voltage converter only helps if the supply is different. In the Solomon Islands the mains voltage lines up with the UK, so there’s no need.
It’s worth checking your device’s voltage rating first. A label showing ‘100–240 V, 50/60 Hz’ means it’ll work abroad without a converter.
