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

If you're heading to Guinea 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 Guinea uses Type C and F and K. 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 Guinea at 220V/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.

Most modern phone chargers, laptop adapters, and camera chargers are designed to handle 100-240V input, so they'll work anywhere with just a plug adapter. Heat-producing appliances like hair dryers and flat irons are often single-voltage, so check before you plug them in abroad.
