Costa Rica to Solomon Islands: Complete Plug & Adapter Guide (2026) Adapter Needed

If you're heading to Solomon Islands from Costa Rica, it's worth checking the power situation before you pack. Different countries use different outlet types and electrical standards, so your devices may not plug in directly when you arrive.

Costa Rica uses Type A and B plugs, while Solomon Islands uses Type G and I. Since there is no overlap, you will need a travel adapter to plug in your devices. Make sure to pick one up before your trip or at the airport.

The electrical standards differ significantly: Costa Rica operates at 120V/60Hz and Solomon Islands at 230V/50Hz. For single-voltage appliances (hair straighteners, kettles, etc.), this mismatch could damage your device or even be a safety hazard. Always verify your device's voltage rating before plugging in.

When packing for Solomon Islands, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
