Voltage: Macau uses 220V, 50Hz alternating current. Plug Types: Three types are in use: British-style three rectangular pins (Type G), European two round pins (Type C), and American two flat pins (Type A). Most accommodations have at least one Type G socket.
Adapters: Bring a universal power adapter compatible with multiple standards. Available at electronics shops, airports, and hotels. Consider a voltage converter for devices designed for 110V if bringing US electronics.
Charging: Most hotels provide USB charging ports in rooms. Mobile phone chargers operate on 220V; verify before plugging in. Power banks are recommended for day trips and extended activities outside hotels.
Safety: Electrical standards are reliable and well-regulated. Avoid overloading circuits. Water resistance near bathrooms is important due to humidity. Power outages are rare in modern infrastructure areas.
