Travel adapter from Antigua and Barbuda to Portugal
Adapter Required
Yes — coming from Antigua and Barbuda, you will need a travel adapter for Portugal. Antigua and Barbuda uses Type A/Type B plugs, and Portugal uses Type C/Type F, so the pin shapes will not fit any wall socket. 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.
