Compare the plug shapes, voltage and frequency in Antigua and Barbuda and Macau, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Antigua and Barbuda, you will need a travel adapter for Macau. Antigua and Barbuda uses Type A/Type B plugs, and Macau uses Type G, 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.
Frequency differs (60 Hz vs 50 Hz). Rarely an issue for most electronics, but can affect motor-driven devices like clocks and shavers.
