What is the plug standard for hotels in Hong Kong?

The plug standard of Hong Kong hotels is English plug. British plug has three square pins with "ELN" three poles, Earth is the ground wire, L Live is the live wire and NNull is the zero wire. There is a difference between the plug and the plug in the mainland, so it needs to be used safely. If you need to use electrical products with other voltages, you need to prepare a transformer. Some hotels may also set up one or two ordinary 2 plugs (domestic) or 3 plugs (domestic) to meet the needs of tourists from different regions. For details, please check the hotel official website or consult the hotel staff.
