Hong Kong is one of the easiest Asian destinations for UK travelers and a quick adapter pick for everyone else. The territory uses Type G plugs identical to the UK at 220 V mains. Despite the 1997 handover to China, Hong Kong has kept its own electrical standards as part of the "one country, two systems" framework.
Quick answer by origin:
- From the US or Canada: Adapter required. Voltage check required.
- From the UK or Ireland: Nothing needed.
- From the EU (Schengen): Adapter required. Voltage match is fine.
- From Australia or NZ: Adapter required. Voltage match is fine.
- From mainland China: Adapter required (different plug type).
What plug does Hong Kong use?
Hong Kong uses Type G plugs throughout the territory. The standard is functionally identical to British BS 1363:
- Three rectangular pins in a triangular pattern
- Built-in fuse (typically 3 A or 13 A)
- Sleeved live and neutral pins
- Socket shutters that only open when the earth pin is fully inserted
- Switched outlets (every Hong Kong wall socket has a switch beside it)
Hong Kong has maintained Type G as the legal standard through the 1997 handover to China and continues to use it exclusively. New construction, mall outlets, MTR (subway) stations, and public charging stations all use Type G.
Hong Kong's voltage and frequency
Hong Kong runs at 220 V, 50 Hz. The grid is operated by CLP Power (Kowloon and the New Territories) and HK Electric (Hong Kong Island). Both deliver stable voltage with typical variation under 2% from spec.
For US and Canadian travelers, this is roughly double your home 120 V mains. The dual-voltage check matters.
For UK, EU, Australian, and most Asian travelers, voltage matches.
Do I need a travel adapter for Hong Kong? By origin country
From the United States or Canada
Adapter required. US plugs don't fit Type G sockets. Buy a US-to-UK adapter ($5-15) which works in Hong Kong identically.
Voltage check: every device needs 100-240 V on the brick. Single-voltage US appliances will burn out at Hong Kong mains.
From the United Kingdom or Ireland
Nothing needed. Your Type G plug fits Hong Kong sockets directly. Voltage matches at 220-230 V. Some UK appliances may run very slightly differently due to the 220 V vs 230 V tolerance but functionally everything works identically.
From the EU (Schengen area)
Adapter required, voltage match is fine. Europlugs, Schuko, French Type E, and Italian Type L all fail in Type G sockets. Any EU-to-UK adapter works.
From Australia or New Zealand
Adapter required, voltage match is fine. AU Type I doesn't fit Type G. AU-to-UK adapters cover the gap.
From mainland China
Adapter required. Mainland China uses Type A, C, and I. None of those fit Hong Kong Type G sockets. If you're crossing from Shenzhen to Hong Kong, expect to need a different adapter than the one you used in mainland China.
From other Type G countries
Nothing needed. UK, Ireland, Singapore, Malaysia, UAE, and other Type G nations all work directly.
Hong Kong vs mainland China
Travelers often visit both Hong Kong and mainland China on the same trip. Power-wise they're different:
- Hong Kong: Type G plugs, 220 V at 50 Hz
- Mainland China: Type A, C, and I plugs, 220 V at 50 Hz (voltage matches)
Crossing the border (or arriving at HKG vs PVG/PEK) requires switching plug shapes. A universal adapter handles both; carrying a UK-only adapter for Hong Kong then needing a separate adapter for mainland China.
Practical answers for common Hong Kong travel situations
Will my MacBook charger work in Hong Kong? Yes. All Apple chargers are dual voltage. Add a US-to-UK adapter if flying from the US.
Are Hong Kong hotels reliable for power? Yes, extremely. The grid is among the most stable in Asia. Even budget hostels in Mong Kok have modern Type G outlets.
Can I buy an adapter at Hong Kong International Airport (HKG)? Yes, at airport markup: HKD 60-150 ($8-19) for adapters that cost HKD 25-50 at any Fortress, Watson's, or Hong Kong electronics shop.
What about USB outlets in Hong Kong hotels? Mid-range and higher hotels have USB outlets at bedsides and desks. Modern Hong Kong properties (Conrad, Mandarin Oriental, Four Seasons, Cordis) have dedicated USB-A and USB-C charging stations.
What about charging on the MTR or Star Ferry? MTR stations don't have public charging at platforms but most have USB outlets in the connecting tunnels. Star Ferry boats don't have outlets. Plan ahead.
Will my UK three-pin shaver charge in Hong Kong? Yes, directly. Same Type G socket, same 220-230 V mains.
Charging multiple devices at once
Hong Kong outlets typically come in pairs per faceplate in modern hotels, often with switches like the UK. For travel charging:
- A GaN multi-port charger with a Type G plug, charges 4 devices off one socket
- A Type G-input travel power strip with 2-3 universal sockets
- A USB-C hub charger that plugs into Type G
Hong Kong sockets deliver 13 A per outlet (2,860 W at 220 V), enough for any travel charging setup.
The bottom line
Hong Kong is one of the easier Asian destinations for travelers, especially UK and Irish ones. Standard Type G sockets, stable 220 V mains, modern infrastructure throughout.
For UK and Irish travelers: nothing to pack beyond what you'd take to London. For everyone else: one Type G adapter handles the territory. Remember that mainland China needs a different adapter entirely.
