Adaptor plug changes your appliance plug to fit Peruvian outletsPeru travel adaptor kit has the adapters you will need for traveling to the South America country of Peru. These adaptors allow your North America appliances to fit into Peru wall power outlets. Note that some laptops have a grounded, three prong plug and require a grounded adaptor... NONGROUNDED ADAPTERS | Going In Style offers non-grounded adapter plugs for use with your voltage converter, transformer, or dual/multi voltage appliance. A non-grounded United States plug has two flat blades. Peru operates on 110-220 volt electricity and is generated at 50-60Hz (Cycles) Alternating Current. United States 110-120 volt electricity is generated at 60Hz (Cycles) Alternating Current. This difference in cycles may cause the motor in your 60Hz United States appliance to operate slightly slower when used on 50Hz foreign electricity. Most modern electronic equipment including battery chargers, Lenovo, HP, Asus, Toshiba computers, iPods, etc., will not be affected by the difference in cycle. Going in Style adapters allow electrical connections up to 240 volts. Adapter plugs DO NOT convert voltage and only change the configuration of the pins. When voltage conversion is needed, use an electricity converter. An electricity converter changes the voltage input into your appliance. The United States electrical appliances operate on a lower current of 110-120 volts AC (Alternating Current). Most of the world operates on 220-240 volts AC. Therefore converter units enable your electronic and non-electronic appliances to run on foreign electricity (220-240 volts) to match the voltage requirements of your 110-120 volt device. Failure to run your appliance with a converter could damage your appliance.
