Travel adapter from Guinea-Bissau to Costa Rica

Compare the plug shapes, voltage and frequency in Guinea-Bissau and Costa Rica, and find out which adapter you need before you travel.

Adapter required

Yes — coming from Guinea-Bissau, you will need a travel adapter for Costa Rica. Guinea-Bissau uses Type C/Type F plugs, and Costa Rica uses Type A/Type B, so the pin shapes will not fit any wall socket. Voltages differ (230 V at home vs 120 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not. The mains frequency is also different (50 Hz vs 60 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.

Voltage converter may be needed. Check your device label — most modern electronics (phones, laptops) support 100–240 V and only need a plug adapter. Hair dryers, kettles, and older appliances may need a step-up or step-down converter.
Frequency differs (50 Hz vs 60 Hz). Rarely an issue for most electronics, but can affect motor-driven devices like clocks and shavers.
