Compare the plug shapes, voltage and frequency in Slovenia and Antigua and Barbuda, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Slovenia, you will need a travel adapter for Antigua and Barbuda. Slovenia uses Type C/Type F plugs, and Antigua and Barbuda uses Type A/Type B, so the pin shapes will not fit any wall socket. 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.
