Do I need to bring a converter to travel to Japan?

There are many friends who have traveled to neighboring countries in recent years, but there are indeed many differences between foreign countries and China. This small series will tell you whether you need to bring a converter to Japan.

Do I need to bring a converter to travel to Japan? No, just use it directly. It's only 1 10 volts, which is a little slow.

Basically, they all use sockets, and some hotel colleagues provide various switch charging lines.

You can charge your mobile phone directly, but if you want to use a computer, you need to borrow a converter from the front desk.

99% of sockets in Japan are two-phase flat sockets, so if you plug in three-phase and two-phase round pins, you need a power adapter.

The single-phase electricity in China is 220V, and the floating value is-10~+7, that is, it is between (198~235.4V).

Household voltages in Japan are single-phase 100V and 200 V, of which the floating value of 200V is -20~+20( 182~222V) based on 202.

First, we take a plug from an electrical appliance in Japan. Take a closer look. In fact, there is little difference between the Japanese double-hole plug and our national standard plug. They are flat double-headed plugs, but if we look closely, we will find that there are two small round holes drilled in the metal plate of the Japanese plug, which are found in almost all electrical appliances without exception.

My friend in Japan told me that this kind of plug is almost the most common in Japan, because Japanese laws and regulations stipulate that two small round holes must be drilled in the plug to produce electrical appliances. If not, it can't be sold in the market. Our country has almost no such rigid regulations on national standard plugs.

Maybe everyone thinks that the difference between our national standard plug and Japanese plug is only the difference between perforated and non-perforated plugs. Everything else is similar, there is no difference. So how can these two small round holes be safer?

It turns out that as long as we carefully observe the bronze medal on the socket, we will know why the plug is plugged into the socket. The reason is that after the plug enters the socket, the bronze medal of the socket can block the plug and transmit electricity. The small round hole of the Japanese plug can make the plug and socket lock more tightly and flexibly, and it will not loosen when inserted, so it will hardly ignite.
