Voltage: Brasília operates on 220 volts, 60 Hz electrical system. Most modern appliances are dual-voltage (110-220V) but verify specifications before connecting.
Brazil uses multiple plug standards: Type N (three round pins in triangular arrangement), Type C (two round pins), and older Type A/B formats in some locations. Universal adapters accommodating multiple plug types are essential.
Brasília's modern infrastructure provides consistent electrical supply with minimal outages. Surge protectors recommended for sensitive electronics in hotels or residences.
