Do I need to take an adapter to Dubai? Are they the same as those in Hong Kong?

You need an adapter to go to Dubai, just like Hong Kong. China and Hongkong use triangular flat plug, 220v, 50Hz. The United States uses a two-pin flat or two-pin flat plus circular grounding pin plug, with rated voltage and frequency of 120v and 60Hz respectively.

To play abroad, you need to bring some electrical appliances that need to be recharged or connected to the power supply. Due to the different national conditions in the world, the transmission power of each country is also different. Different electricity consumption leads to different voltages in each country, and the socket shape, current frequency and socket specifications are also different. Without proper adapter and current-voltage conversion, some electrical appliances brought out of China can't be used normally.
