Do I need to bring a voltage converter and plug converter when traveling to the United States now?

Yes, electrical appliances with power supply and voltage conversion are required. For example, modern laptops are equipped with transformers. When traveling, you can bring two adapters, American standard ones.

The voltage in the United States/Canada is 110V. Please pay attention to whether the electrical equipment you carry meets the requirements. If the rated power is 220V, it is not recommended to bring it for use, or please bring a transformer. Please also buy a conversion plug in China

In 1879, Edison produced a relatively effective carbon filament incandescent lamp. The incandescent lamp at that time ran well under 110V DC voltage. Edison believed that this was a safe and economical method for power distribution. voltage.

But later, another voltage level - 220V was also recommended for use in the low-voltage field.

After the two geniuses Edison and Tesla had a big fight over the issue of "is DC stronger or AC is stronger?", the United States slowly began to generally adopt 110V AC.

Other countries

The power supply voltage in Singapore is 220-240 volts alternating current, the frequency is 50 Hz, and the plug is a British-style square triangle Large plug; need to bring conversion plug. Under normal circumstances, hotels will provide conversion plugs, but they may not be sufficient. It is recommended to bring your own.

The voltage of the UAE is 220v (British standard, thick triangle plug). The socket type is inconsistent with that in China. It is recommended to bring your own conversion plug< /p>

Egyptian sockets have two round holes, and the voltage is 220V, 50Hz. Chinese electrical appliances can be used normally in Egypt without a transformer, but they require a plug adapter.

If the voltage specification of your electrical appliance does not meet this, you will also need to bring your own transformer
