Peru’s Plug & Power Standards

1. Plug Types:
   • Type A: Two flat, parallel pins (North American standard). Most common.
   • Type C: Two round pins (European standard). Very common, especially in newer buildings, hotels, and areas with 220V.
   • Less Common: Type B (Type A + ground pin) is occasionally found, especially on higher-power appliances or in newer constructions, but not widespread. Type F (C with side ground clips) is also seen sometimes.
2. Voltage:
   • Dual Voltage System: This is the crucial point.
     • 110V / 120V: Found in most of coastal Peru (Lima, Trujillo, Chiclayo) and the western regions. Predominant in older areas.
     • 220V / 230V: Found in most of the Andes (Cusco, Arequipa, Puno, Huaraz) and the Amazon (Iquitos, Puerto Maldonado). Predominant in these regions, especially newer buildings.
   • Important: Always check the voltage at your specific location! Outlets are not always clearly labeled. Plugging a 110V device into 220V will likely destroy it. Plugging a 220V device into 110V may simply not work properly.
3. Frequency:
   • 60 Hz throughout the country. Consistent with North America, different from Europe’s 50Hz. This mainly affects timing motors in devices like clocks or some older appliances; most modern electronics (laptops, phone chargers) handle 50/60Hz fine.

Key Considerations for Travelers:

• Bring Adaptors: Carry both Type A (N. American) and Type C (Euro) plug adaptors. A universal adaptor is highly recommended.
• Check Device Voltage: Crucial! Look at the label on your charger or device (e.g., “Input: 100-240V, 50/60Hz”). If it says “100-240V” or “110-240V”, it will work safely anywhere in Peru with just a plug adaptor.
• Single-Voltage Devices (110V only or 220V only): You will need a voltage converter/transformer for regions with the opposite voltage. Highly recommended to avoid bringing these if possible.
• USB Charging: USB ports (like on laptops or dedicated USB chargers) almost always support 100-240V. You’ll only need the plug adaptor.
• Hotels: Many tourist hotels, especially higher-end ones, may have outlets that accept multiple plug types (A, C, sometimes B) or even provide 110V and 220V sockets. Some also have USB ports built-in. However, never assume.
• Machu Picchu / Aguas Calientes: Primarily uses 220V and Type C plugs.

In summary:

• Plugs: Primarily Type A (flat pins) and Type C (round pins). Bring both adaptors.
• Voltage: Either 110V or 220V - check locally! Coastal/West often 110V; Andes/Amazon often 220V.
• Frequency: 60 Hz everywhere.
• Best Practice: Use dual-voltage devices (100-240V) and bring Type A & C plug adaptors (or a universal adaptor). Check voltage at your outlet before plugging in sensitive electronics. Avoid single-voltage appliances if possible.
