Voltage & Frequency: Belgium operates on 230V at 50Hz, standard throughout the European Union. This differs from North America (110-120V, 60Hz) and some other regions.
Plug Types: Belgium uses Type E plugs (two round pins with hole for earth pin) and also accepts Type C (European two round pins without earth). Type E is the official Belgian standard with a male grounding pin protruding from the socket.
What You Need:
Where to Buy Adapters: Available at Brussels Airport shops, electronics stores throughout city, and many hotel reception desks (sometimes for loan). Better to buy before travel as airport prices are inflated. Universal travel adapters cover Belgium and worldwide destinations.
Hotel Considerations: Most hotels provide 230V power. Higher-end hotels may have international sockets (110V and 230V) or USB charging ports. Ask reception about adapter availability. Bathrooms may have special shaver sockets (110-120V) marked clearly.
USB Charging: Increasingly common in hotels, cafes, airports, and public spaces. Voltage conversion automatic with USB - just need any USB cable. Many Brussels hotels have USB ports built into rooms.
Multiple Devices: Bring power strip/extension from home (with appropriate voltage) to charge several devices from single adapter. Alternatively, buy European power strip in Brussels electronics store.
