Soon, Europe introduced the AC power transmission technology. Q: Why are there so many different voltage levels? Can they be unified?Ī: At the end of the 19th century, the United States took the lead in adopting the 110V voltage specification and built the 110V/60Hz standard grid. If not, then you need to equip the voltage converter to get your appliance working properly. In fact, the current global civil exchange standard voltages are two:Ģ20V region (220~240V): China, Britain, Germany, Australia, Singapore and more than 120 countries and regionsġ10V region (100~130V): the United States, Canada, Japan, China Taiwan and more than 30 countries and regionsīuying electrical appliances from abroad, we must first consider whether they cannot be used. To be safe, you'll need a GoHz voltage converter. Common conversion plug power is only 60W, but household appliances power generally much higher, such as rice cooker power is at least 600W, most common is 1000W-1500W. Some people may think that voltage converting is very simple? A travel plug can do the job! Actually, it can't. The only solution is to convert the 220V home electric into 110V, so be sure to use the voltage converter. Especially, for voltage and current sensitive smart chip, it will easy to be burned, and hard to be repaired and replaced, the cost may also be very expensive. In other words, if a Japanese original electrical appliance is directly used under 220v, it will be broken. If a low rated voltage is inserted into a high voltage power supply, the appliance may be burned out. Electrical appliances with high rated voltages may not operate when plugged into a low-voltage power source. Electrical appliances of these countries are designed to adapt to the local voltage level. That is because many countries use 220V AC, while Japan uses 100V AC, and the US uses 110V AC outlet. In fact, not only Japan's rice cooker, the coffee machines, ovens and other appliances from the United States are not easy to use at home. Have you ever purchased a foreign electrical product?Ī friend said the rice cooker he bought from Japan cannot be used at home.
