Compare the plug shapes, voltage and frequency in Cuba and Cape Verde, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Cuba, you will need a travel adapter for Cape Verde. Cuba uses Type A/Type B plugs, and Cape Verde uses Type C/Type F, so the pin shapes will not fit any wall socket. Voltages differ (120 V at home vs 230 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 (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
