Quick answer
St. Lucia uses Types A, B and G at 240 V. Some outlets in St. Lucia take U.S. plugs, but others are Type G. Pack a Type G adapter to be safe. 240 V is about twice the 120 V of the United States. Chargers marked 100–240 V (phones, laptops, cameras) only need an adapter; single-voltage devices such as hair dryers and straighteners need a converter, or bring dual-voltage ones.

What to pack for St. Lucia
- A Type G plug adapter, one per device you charge at the same time.
- Dual-voltage hair tools, or a voltage converter if yours are 120 V only.
- Leave U.S. power strips at home: most are rated for 125 V, not 240 V.
Check the label first
Look for the input line on your charger or device. INPUT: 100–240V means it works anywhere with just a plug adapter. A single number such as 120V means it only works at that voltage.
