Quick answer
Montserrat uses Types A and B at 230 V. U.S. plugs fit the outlets in Montserrat. 230 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 Montserrat
- No plug adapter: your U.S. plugs fit.
- 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 230 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.
