Austria uses 230 volts AC, 50 Hz — the same standard as most of continental Europe.
Austria uses Type C (European two-round-pin) and Type F (Schuko, two-round-pin with grounding) plugs. These are standard throughout continental Europe.
North American Travelers (110V): Require voltage converters AND plug adapters. Travel converters available at electronics stores cost €15-40. Consider purchasing before travel or at airport shops. UK/Irish Travelers: Require plug adapters only (Type G plugs). Australian/NZ Travelers: Require plug adapters and voltage converters.
Airport electronics shops sell standard European adapters (€8-15). City center electronics retailers like MediaMarkt or Saturn stock full ranges. Hotels can usually provide adapters for guests. Multiple USB ports are increasingly common in hotels and cafés.
Austrian electrical standards are strict and safe. Ground your connections. Use hotel safe for valuable electronics. Power outages are rare. Many accommodations include universal sockets.
