Solomon Islands Travel Adapters
Type I (Australian Plug) • 230 volts • 50 Hz
Guadalcanal, the Solomon Islands' largest island, was the site of a pivotal World War II campaign fought from August 1942 to February 1943. The Allied victory there marked Japan's first major land defeat of the war and a turning point in the Pacific campaign.
Solomon Islands uses mains electricity supplied at 230 volts at 50 Hz. Wall outlets in Solomon Islands use Type I, the same plug used in Australia and New Zealand and often called the Australian plug.
Travelers from the U.S. using Type A or Type B plugs need a travel adapter for the Solomon Islands that covers Type I. A travel adapter changes the plug shape only and does not convert voltage. Devices marked for 100–240V input can be used on the Solomon Islands' 230V supply with the correct adapter; equipment that is not dual voltage requires an appropriate voltage converter.
What Plug Type Does the Solomon Islands Use?

Adapter may also be spelled adaptor. Converter may be spelled convertor. Grounded may also be described as earthed.
Solomon Islands uses the Type I plug and outlet system, the same standard used in Australia and New Zealand. Some other adapter guides also list Type G for the Solomon Islands. We checked this independently: the Solomon Islands Electricity Authority's own technical documentation and multiple standards references list Type I only, so Type G is not included on this page. Bring a Type I adapter regardless; if you also happen to have a Type G adapter on hand, it won't hurt to pack it, but it should not be necessary.

Do I need a voltage converter for the Solomon Islands?
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 the Solomon Islands' Type I outlets. 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 the Solomon Islands?
Phone and laptop chargers use a universal 100–240V power supply, so yours will work on the Solomon Islands' 230V supply without a separate converter. You'll still need a Type I plug adapter, since the charger's US plug won't physically fit the Solomon Islands' outlets.
Are the Solomon Islands and US power outlets interchangeable?
No. Solomon Islands uses Type I outlets and the US uses Type A/B. The plug shapes are different, and Solomon Islands 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 Solomon Islands use the same plug as Australia?
Yes. Solomon Islands uses the same Type I plug and outlet system used in Australia and New Zealand, so a Type I travel adapter that works for those countries also works in the Solomon Islands.
