Although technology is helping to make the world seem a lot smaller, there are still major differences between countries. Electrical standardization is one area where not much has changed since the original national standards were set by each country. If you travel a lot, this can make things very frustrating! The United States and most of the Western hemisphere use electrical systems operating at volts.
Almost every other country uses volts as a standard. The v systems have a 60Hz cycle while most of the v systems operate at 50Hz. This difference in cycles per second is not normally a big deal but it can make certain items like electric clocks run faster or slower. With a few exceptions, most notably Brazil and South Africa, alternating current AC is the method used to deliver electricity. But be aware of those countries that use direct current DC -- it can easily destroy any equipment plugged in that wasn't made to operate in that system.
The adapter is simply a connector that changes the plug shape to match the outlet. It does not change the voltage or electrical output in any way. If you know that the plug shape is the only difference between your equipment and the electrical system you are planning to use, then an adapter is all you need.
Below is a list that gives an idea what the wattage of common appliances is. Use this as a guide only. Always check your appliance first!
Transformers and converters only convert the voltage, not the frequency. The difference in cycles may cause the motor in a 50 Hz appliance to operate slightly faster when used on 60 Hz electricity. This cycle difference will cause electric clocks and timing circuits to keep incorrect time: European alarm clocks will run faster on 60 Hz electricity and American clocks will lose some 10 minutes every hour when used in Europe. However, most modern electronic equipment like phone chargers, laptops, printers, etc.
Just take a look at the glass of an ordinary light bulb or stop at a supermarket and note what is printed on a light bulb packet!

Useful information for travellers. Last updated: 17 July Useful information for travellers Only use plug adapters if the local mains voltage is the same as at home or if you need to power a multi-voltage device.
Travel adapters do NOT convert the voltage! Converters Converters and transformers both step up or down the voltage, but there is a difference in use between them. Check out all plug types used around the world. Type B. Type C. In summary, if you are traveling to a foreign country, you will most likely need to bring along an adapter.
However, you only need a converter if your appliances are not dual voltage and not compatible with the electricity in your destination country. You can avoid packing a converter by making sure all your appliances are dual voltage before you leave for your trip.
