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

Heading from Guinea to Costa Rica? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Guinea uses Type C and F and K plugs, while Costa Rica uses Type A and B. 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.

Voltage is another key difference. Guinea uses 220V while Costa Rica uses 120V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

When packing for Costa Rica, 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.
