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

Yes, you need electrical appliances with power supply and switching voltage. For example, all laptops now have transformers. If you travel, you can bring two adapters, American standard.

The voltage in USA/Canada is 1 10V. Please pay attention to whether the electrical equipment you carry meets the requirements. If the rated power is 220V, it is not recommended to carry it with you, or please attach a transformer. Please also buy an adapter in China.

1879, Edison produced a carbon filament incandescent lamp, and the effect was very good. At that time, incandescent lamps operated well at DC voltage of 1 10V, which Edison thought was a safe and economical voltage in power distribution.

However, another voltage level, 220 V, was later recommended in the low-voltage field.

After Edison and Tesla had a big debate about "strong DC or strong AC", the United States gradually began to adopt 1 10V AC.

other countries

Singapore's power supply voltage is 220-240 volts AC, the frequency is 50 Hz, and the plug is a British square triangle plug; You need to bring a conversion plug. In general, the hotel will provide a conversion plug, but it may not be enough. It is recommended to bring your own.

The United Arab Emirates uses a voltage of 220v (British standard, thick triangular plug), and the socket type is different from that in China. It is recommended to bring your own conversion plug.

The socket in Egypt is round with two holes, and the voltage is 220V and 50Hz. China's electrical appliances can be used normally in Egypt without transformer, but they need to be plugged in. If the voltage specification of your electrical appliance can't meet this requirement, you need to bring your own transformer.
