Voltage & Frequency: Cambodia uses 220 volts at 50 Hz electrical standard, different from North American 110V/60Hz.
Plug Types: Cambodia primarily uses Type A (two flat parallel pins, US standard) and Type C (two round pins, European standard) outlets. Some older buildings may have Type I (Australian three flat parallel pins).
Adapter Requirements: Visitors from North America need voltage converter for 110V appliances or buy dual-voltage devices. European visitors need Type A-to-C converters if devices are EU-plug equipped. Bring universal adapters to handle multiple outlet types.
Practical Tips: Most hotels provide adapters or can source them locally. 7-Eleven stores and electronics shops sell adapters (2,000-8,000 KHR). Power outages occur occasionally in rainy season; carry power banks for device charging. Electrical infrastructure in city center is reliable; older buildings may have unreliable power.
