How it works
The UK uses type G plugs (three rectangular pins), which few other countries use. Most of Europe uses round-pin type C, E and F sockets, North America uses flat-pin types A and B, and Australia uses type I. Choose your destination to see what you need.
Voltage matters too. Most of the world runs at 220–240V like the UK, so an adapter is all you need. In the USA, Canada, Japan and parts of the Caribbean and Latin America it's 100–127V. Phone and laptop chargers cope fine, but UK hairdryers and straighteners usually don't.
Worked examples
- Spain → Need an adapter?: Yes · Plug types used: Type C, F · Voltage: 230V, 50Hz
- USA → Need an adapter?: Yes · Plug types used: Type A, B · Voltage: 120V, 60Hz
- Dubai (UAE) → Need an adapter?: Probably — pack one · Plug types used: Type C, D, G · Voltage: 230V, 50Hz
- Cyprus → Need an adapter?: No · Plug types used: Type G · Voltage: 230V, 50Hz
- Japan → Need an adapter?: Yes · Plug types used: Type A, B · Voltage: 100V, 50/60Hz
Common questions
Do I need an adapter for Spain?
Yes. Spain uses type C and F (two round pins), so you need a European adapter. The voltage is 230V, so UK appliances work.
Will my UK hair straighteners work in the USA?
Usually not properly. The USA runs at 120V. Unless the label says 100–240V (dual voltage), you'd need a voltage converter, not just an adapter.
Which countries use the same plug as the UK?
Ireland, Malta, Cyprus, Hong Kong, Singapore, Malaysia and Kenya all use type G. It's also common in Dubai, Qatar, Sri Lanka and the Maldives.
What is the difference between an adapter and a converter?
An adapter just changes the plug shape. A converter changes the voltage. Most modern chargers only need an adapter.
