From Sint Maarten to Hong Kong
When travelling from Sint Maarten to Hong Kong: None of your Sint Maarten plug types fit in Hong Kong. You will need a travel adapter. Voltage is different (110V → 230V). Check your charger label; if it doesn’t list 230V you’ll also need a voltage converter. Frequency differs (60Hz → 50Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.

About electricity in Hong Kong
Hong Kong runs on 230V/50Hz with Type G, the same three-rectangular-pin socket used across the UK.
Grid & history
Two private utilities, CLP and HK Electric, supply the city primarily from natural gas, with some nuclear imported from Daya Bay across the border in Shenzhen.
Availability
Outages are extremely rare.
Sockets & hotels
Type G is universal, and UK plugs fit perfectly. Older tenement buildings may still have ungrounded sockets, though the plug shape is the same.
Energy mix
Coal and gas dominate; nuclear is imported.
Practical tips
- A Type G adapter is essential for non-UK plugs.
- Voltage is 230V, so standard chargers handle it without issue.
