Voltage: Cambodia operates on 220V, 50Hz electrical standard. This is significantly higher than North American 110V standard, so voltage conversion is necessary for US/Canadian appliances.
Plug Types: Two main types dominate: Type A (2-flat pins, US-style) and Type C (2-round pins, European-style). Many outlets accept both types. Type A is most common in Siem Reap.
What You'll Need: A universal power adapter accommodating both Type A and Type C plugs is essential. Purchase before traveling or at airport shops. For devices requiring different voltage (hairdryers, electric razors, laptop chargers), use a voltage converter or bring dual-voltage devices.
Power Reliability: Siem Reap's electrical infrastructure is generally reliable, though occasional blackouts occur during peak demand or bad weather. Hotels almost always have backup generators. Power strips with surge protection protect devices from unexpected voltage spikes.
Recommendations: Bring universal adapter and voltage converter. Mobile phone chargers and laptops are typically dual-voltage (check labels). Charge devices at night in hotel. Carry a portable power bank for mobile phones during day trips.
