How Does Electricity & Plugs Work in Hong Kong?
Last verified: 2025-06 · Asia
1The Quick Answer
Hong Kong uses Type G plugs (British 3-pin square) at 220V/50Hz — the same as the UK — so US and European visitors need an adapter.
2What You Need to Know
Hong Kong uses the British-style Type G three-pin square plug socket at 220 volts and 50Hz, a legacy of British colonial rule. Visitors from the United States, Canada, Japan, and most of continental Europe will need a plug adapter. Most modern electronic devices (laptops, phone chargers, camera chargers) are dual-voltage (100–240V) and only require an adapter, not a voltage converter. Hong Kong has a very reliable power supply with extremely rare outages. Adapters are available at the airport, electronics stores in Sham Shui Po, and most hotel gift shops.
