Montserrat uses plug types A and B. The most common is type B – the North American three-prong plug.
The mains voltage in Montserrat is 230 V and the frequency is 60 Hz. Devices from countries with 220–240 V work without a converter. Devices from countries with 100–127 V (USA, Canada, Japan) should only be plugged in if the power supply says 100–240 V.
You need an adapter if your devices have plugs other than types A and B. You won’t need one if you’re coming from Canada, Japan and United States. Only some plugs fit for travellers from China. Travellers from Australia, France, Germany, India, Poland and United Kingdom need an adapter to type B.
Not if you’re coming from Australia, China, France, Germany, India, Poland and United Kingdom – the voltage is similar. If you bring devices from Canada, Japan and United States, check their rating labels. Phone and laptop chargers usually work on 100–240 V, but hair dryers, straighteners and kettles often do not – those need a voltage converter.
