Look at how many countries in East Asia and North America have ridiculously low voltages. Japan directly operates at 100V, and the US at most 120V. I really don’t understand why they insist on low voltage. If we take a hairdryer from China abroad, it won’t even turn on, almost like running out of air; conversely, if they bring small appliances to China, they might get burned out and smoke. Whoever encounters this confusion is stunned.

Interestingly, 220V is the mainstream configuration in our region! From China and Korea to Russia, Argentina, and Thailand, it’s all this voltage, just with a slight difference in frequency — we use 50Hz, while Korea prefers 60Hz.

When it comes to voltage, it’s really just a matter of each country setting their own standards back in the day. The one that was established first has been used ever since, and no one wants to bother changing everything now.

Further into Europe and Australia, the voltage quietly increased by 10V, mostly stabilizing at 230V, and they are especially considerate by supporting a range from 220V to 240V. Most new appliances now are designed for wide voltage compatibility, so even across regions, they usually work fine.

But everyone should really check the local standards before traveling abroad. Don’t excitedly bring your new beauty devices or shavers, only to find they don’t work and end up as paperweights. That’s such a loss. $DOGE
