You can use a 110V Appliance in countries that use 220V, provided you use a voltage converter. The voltage converter should be able to convert the power supply of 220V to the requirement of the device – 110V and thus allow the device to operate properly.
That is because many countries use 220V AC, while Japan uses 100V AC, and the US uses 110V AC outlet. Electrical appliances of these countries are designed to adapt to the local voltage level. Electrical appliances with high rated voltages may not operate when plugged into a low-voltage power source.
Key Takeaways: Countries in North America, the Caribbean, and certain areas of the Pacific use 110 volts at 60 hertz, whereas the rest of the globe uses 220 volts at 50 hertz. The voltage ranges covered by 110V and 220V are 100-125V and 220-250V, respectively. In many nations, you will also find both 110V and 220V outlets.
If you take a scroll down the page, you will notice that most countries have a well-defined plug and voltage standard. Many Latin-American, African and Asian countries, however, use a motley collection of – often incompatible – plugs and sometimes also the voltage differs from region to region.
To use your 110V household appliances from the United States in nations that utilize 220V electricity, you’ll need a step-down voltage converter or transformer. On the other side, if you have a step-up voltage converter/transformer, you may use 220V appliances in the United States that normally require 110V.
But, the 110V voltage is too low, transmission loss is too high, in order to improve this situation, Europe using the 220V voltage specification. So the European countries use the form of 220V/50Hz AC grid standards. The industrial system of each country has been formed for more than 100 years, and cannot be subversive unified revision.
