When traveling abroad, if it is the first time to visit a country, many people will definitely worry about whether Taiwan’s plugs can be used directly there. Although many hotels provide free rental adapters, the number is limited, and cheap hotels or backpacker inns do not have this service. In addition, there are voltage issues.
This article recommends a very easy-to-use CheckPlug website. Not only can you quickly check the socket style and voltage standards of the country you are traveling to, but you can also compare them with Taiwan or other countries, so you don’t have to worry about forgetting to bring an adapter or avoiding wrong voltages.

CheckPlug quickly checks the socket and voltage standards of the country you are traveling to, and whether you need an adapter.
CheckPlug is a free query tool developed abroad. Although it is only in English, the operation is very simple. After entering the website, select the current country and travel destination country, and then you can obtain relevant information.
In addition, when making inquiries, remember to not only look at the socket style, but also what the local voltage is, and whether the plugs and chargers you plan to bring support international voltages? If there is only a single voltage and the voltage at the tourist destination is different, then it cannot be used. This should be noted.
After clicking the link above to enter the CheckPlug website, the top I’m from selects the country you are currently in, such as Japan, Taiwan, and the default will be your current location. The bottom I’m going to is the country of the travel destination. Some popular travel countries are also displayed at the bottom to facilitate your quick selection:

It is available in almost all countries/regions around the world. The names are arranged alphabetically and the search function is also supported. You can directly enter keywords to quickly find:

After selecting, click Check Plugs below. I chose Taiwan and Brazil:

Then the socket types, voltages and frequencies used in Taiwan and Brazil will be listed, and the diagram will be used to tell whether there are any differences between the two countries at a glance. When traveling to Brazil from Taiwan, you must bring an adapter. The socket types are completely different. Taiwan has Type A and Type B, while Brazil has Type C and Type N.
The voltage part is also relatively high. Brazil requires 127V, while Taiwan requires 110V. Therefore, you can only use chargers that support international voltage (100V ~240V). A simple 110V charger cannot be used in Brazil:

If you find English difficult to read, you can use the browser’s translation function to translate the entire page into Traditional Chinese, so that it becomes Chinese.
Many chargers now support international voltages, especially mobile phones and laptops. If you don’t know, just look at the words on the charger to see if it says 100V~240V, or on the transformer.
There are currently two basic voltage and frequency standards commonly used around the world, namely 110V~120V, 60Hz and 220V~240V, 50Hz. There are so many sockets, there are about 8 common types, A, B, C, D, E, F, G, H, which are quite complicated. Therefore, before traveling abroad, you must check the local sockets and voltage first, so that you don’t have to worry about the situation where you need to use an adapter but can’t buy it.
