Indonesia operates on 220 volts, 50 Hz AC electrical system. Most modern electronics from various countries will operate safely with voltage converters.
Indonesia uses Type C and Type I plugs:
Type C: Two round pins (common in Europe, Southeast Asia). Most electrical outlets in hotels, shops, and homes use this standard.
Type I: Two flat pins in V-shape with ground pin (Australian standard). Less common but found in newer buildings and hotels.
• Purchase a combination adapter supporting both Type C and I plugs (approximately 50,000-100,000 IDR from local electronics shops)
• Most hotels provide adapters upon request
• Universal travel adapters work but verify Type C/I compatibility before purchase
• Bring adapters from home country as selection in Bandung is limited
Bandung has reliable electricity with occasional brief outages during monsoon season. Hotels and shopping malls have backup generators ensuring uninterrupted power. Water heaters typically require manual switching; ask hotel staff for operation instructions.
USB charging ports are increasingly common in hotels, cafes, and shopping malls. Carry USB power adapters and cables for convenient charging. Power banks (portable chargers) are highly recommended for all-day exploration away from accommodation.
