Hong Kong Power Plug Types and Voltage Guide

1. Power Plug Types

The power sockets in Hong Kong mainly adopt the following two standards:
- British BS 1363 three-pin plug: This is the most common socket type in Hong Kong, consistent with the British standard, characterized by three rectangular metal pins (one vertical, two horizontal).
- Compatible with Mainland China's two-pin flat plug (Type A): Some hotels or newer buildings may offer two-pin flat interfaces, but their prevalence is relatively low.

Suggestion:
- If your device uses American (Type A/B), European (Type C), or other types of plugs, you need to carry a British standard adapter (BS 1363).
- Some hotels may offer free borrowing services, but it is recommended to bring a universal converter to handle various scenarios.

2. Voltage and Frequency

• Voltage: 220 volts (V), consistent with Mainland China and European countries.
• Frequency: 50 hertz (Hz).

Notes:
- If your device comes from Japan, the United States, Canada, or other countries using 110V voltage, you need to confirm whether it supports wide voltage (100-240V). If it only supports 110V, you need to carry a voltage converter separately, otherwise, it may damage your device.
- Modern electronic products (such as mobile phones, laptops, camera chargers) usually support wide voltage and can be used directly.

3. Practical Suggestions

• Adapter Purchase:
• Available at convenience stores in Hong Kong (such as 7-11, OK Convenience Stores), electrical appliance stores (such as Fortress, Broadway), or airport shops, priced at approximately HK$20-50.

• It is recommended to carry a universal converter (with USB interface) for convenient simultaneous charging of multiple devices.

• Hotel Facilities:

• Some high-end hotels provide USB charging ports or international universal sockets; it is recommended to confirm with the hotel in advance.

• Bathrooms may be equipped with 110V shaver-only sockets (requires two-pin round plug).

• Other Devices:

• High-power appliances (such as hair dryers, curling irons) need to confirm compatibility with 220V voltage.
• If you need to use Mainland China’s two-pin plug, pair it with a British standard converter (some sockets may be loose, so it is recommended to prioritize the original adapter).

4. Safety Tips

• Avoid using substandard converters to prevent short circuits or fires.
• Do not connect too many high-power devices simultaneously to avoid overloading the socket.
