Electricity in Peru operates at 220 Volts and 60 Hertz. If you plan to use devices that operate on 110 Volts, it is advisable to bring an adapter to protect your equipment. Some laptops and cameras have dual voltage, but it’s always prudent to check this in advance. Peru uses three types of plugs: plugs with two flat pins, plugs with two flat pins and one rounded pin, and plugs with two rounded pins. If you come from a country with a different plug type, you will need an adapter, which you can purchase at local hardware stores or shopping centers.
