What this means for your trip
Travelling from Ireland to Macau? Easy trip, electrically speaking — you don't need a plug adapter or a voltage converter. Both countries use the same outlet shape and the same voltage standard, so every charger, phone, and laptop you'd normally pack works the moment you land.
Both countries run on Type G outlets. You don't need a shape adapter at all — just plug in the way you do at home.
Voltage is the same on both ends (230V vs 230V, 50Hz vs 50Hz), so every charger that works at home works in Macau without modification. No voltage converter, no hunting for "100-240V" on the brick.
One more thing about Macau: The rest of China uses types A, C, I.
Frequently asked
Do I need a travel adapter for Macau from Ireland?
No. Both Ireland and Macau use Type G outlets, so your plug fits the socket as-is.
What type of plug does Macau use?
Macau uses Type G outlets at 230V, 50Hz. Three rectangular pins. UK, Ireland, Malta, Singapore, Hong Kong, many former UK colonies.
What's the voltage in Macau?
Macau runs on 230V at 50Hz. That's on the high-voltage standard, matching than Ireland's 230V supply. Most modern phones, laptops, tablets, and camera chargers are dual-voltage (check for "100-240V" on the brick) and work on either. Single-voltage devices like hair dryers, curling irons, and travel kettles will not — bring a dual-voltage travel version or a voltage converter.
Are Ireland chargers dual-voltage?
Most — but not all. Check the charger brick for a line that reads something like "INPUT: 100-240V, 50/60Hz." If you see that, the charger works on either voltage standard and you only need a plug adapter. If it lists just "120V" (or just "230V"), it's single-voltage and can't be plugged straight into the other side without a voltage converter.
