Voltage & Frequency: India uses 230V AC at 50Hz frequency, different from many Western countries operating on 110V or 60Hz. Ensure all electronics are compatible or use voltage converters.
Plug Types: India primarily uses Type D (three round pins in triangular pattern), Type A (two flat parallel pins), and increasingly Type G (three rectangular pins). Most hotels provide multiple plug types or adapters.
Adapters & Converters: Universal travel adapters are readily available in electronics stores, supermarkets, and hotel shops across Chennai. For sensitive electronics, consider bringing a step-down converter from your home country for safety.
Power Supply Reliability: Chennai's power supply is generally reliable in developed areas and hotels. Occasional power cuts (loadshedding) can occur, though rare in tourist areas. Most hotels have backup generators ensuring uninterrupted supply.
Where to Buy: Electronics shops on Mount Road, T. Nagar shopping areas, and modern malls sell various adapters and converters. Airport shops also stock travel adapters at premium prices.
USB Charging: Most hotels, cafes, and shopping malls provide USB charging points. Carrying a portable power bank is recommended for day-long excursions.
