Hong Kong is listed with 220V nominal AC supply, 50Hz, and Type G in the reviewed travel references. These figures describe a destination profile, not the outlet in your room.

Before plugging in
The listed plug family is a travel reference, not a guarantee about every building or outlet. Treat mainland China, Hong Kong and Macau as separate electrical profiles.

Illustrations show broad family shapes only. They are not dimensioned drawings or a fit test.
A plug letter identifies a shape family. It does not establish the supply voltage, the exact subvariant, the condition of the wall socket, or a working protective earth. Nominal values can differ from the actual supply at a particular property.
What changes for a US traveler?
A US appliance marked 120V only does not cover every 220V reference candidate. Do not use a plug adapter to bridge that electrical mismatch. The listed plug families differ from common US A/B plugs. Investigate a correctly rated adapter for the actual socket, with protective earth if your appliance requires it. The reference includes 50Hz or an unresolved frequency, so a US 60Hz-only appliance needs a specific frequency check.
- The destination reference cannot answer for an appliance without its INPUT label and grounding classification.
Why some charts disagree
The values below are retained as a research conflict, not silently averaged into a new national standard. An outlet-specific answer matters most for a single-voltage device.
| Field | Values reported | References |
|---|---|---|
| plug types | [["C", "D", "G"], ["D", "G"], ["G"]] | Bel Fuse , MAG Kabel , MENNEKES |
Hong Kong research note
Local regulatory and utility material supports 220V/50Hz. Type G is the main travel planning reference; international C/D listings are facility questions rather than promises about every current guest room.
Check your device label
Find the INPUT line on the item that actually connects to AC power. Confirm its voltage range includes the local supply, its frequency rating includes the local frequency, and its plug and grounding requirements are met. A USB output rating such as 65W is not the AC input rating.
| Device | Check before use |
|---|---|
| Phone and tablet chargers | If the actual charger says INPUT 100–240V 50/60Hz, the listed 220V and 50Hz values are inside those two ranges. Check its wall plug and USB profile separately. |
| Laptop supplies | Inspect the brick and detachable cord. A Type G country listing does not verify a Class I earth path in your room. |
| Cameras and small chargers | Read the battery charger’s AC INPUT, not the camera body. A 120V-only label cannot be cleared for 220V without a maker-approved solution. |
| Hair dryers and heated tools | A US 120V-only heating appliance is outside at least one 220V candidate; a shape adapter is not a converter. |
| Medical and CPAP devices | Ask the maker and care team to compare the exact power supply with 220V and 50Hz; plan a backup rather than relying on a country-level safe-use verdict. |

What adapter type should you look for?
Start with an adapter that explicitly accepts your device’s actual plug and has an output plug matching the outlet shown by your accommodation. Check the adapter’s AC current rating, permitted appliances and earth continuity. A universal adapter can have several pins yet lack protective earth. A shape adapter cannot step voltage up or down.
For Hong Kong, research Type G. Do not buy solely from this country-level listing; ask the property about the exact socket variant first.
- Dedicated destination head: investigate one that names the exact wall socket variant and your device plug.
- Grounded route for Class I equipment: require documented protective-earth continuity from the wall through the adapter.
- Documented universal model: useful for several stops only when every required variant and the AC load are supported.

Travel questions for Hong Kong
Will a US plug connect directly in Hong Kong?
The listed Type G families differ from common US A/B. Look for a device-to-wall adapter for the actual room socket, not a country-name guarantee.
Can I use a device marked 120V only?
Not from the 220V reference alone. At least one candidate is outside a 120V-only label; ask the property and product maker before connecting it.
What should I confirm with the property?
Ask for the voltage and a photo or exact name of the outlet you will use. The local electrical reference with socket caveats research status and Type G listing do not verify every room or a working protective earth.

The research record marks this profile as local electrical reference with socket caveats. If sources disagree, the screening tool requests local confirmation rather than treating a nominal reference as a safety certificate. Report a correction
