110 V at 50 Hz - the only common pairing of American voltage with European frequency.
What you need, by where you are coming from
Arriving from the United States or CanadaPlugs go straight in and the voltage matches. Nothing to pack.
Arriving from the UK or IrelandA plug adapter, and appliances marked 100-240 V. Anything single-voltage needs a converter.
Arriving from most of continental EuropeA plug adapter, and appliances marked 100-240 V. Anything single-voltage needs a converter.
Arriving from Australia or New ZealandA plug adapter, and appliances marked 100-240 V. Anything single-voltage needs a converter.
Socket types, voltage and frequency are the nominal domestic supply as published in IEC/TR 60083 and the national standards it lists.
Jamaican sockets are American Type and at 110 V, but the grid runs at 50 Hz - the only common pairing of the two.
Sockets in Jamaica are Type and at 110 V, 50 Hz - American plugs and voltage on a European frequency.
American and Canadian plugs fit straight in. Everyone else needs an adapter.
The 50 Hz supply is the oddity. Electronics do not care; a mains-timed clock or a motor built for 60 Hz runs slow.
110 V means European 230 V-only appliances will not work.
Unearthed two-slot sockets are common outside the resort hotels.
Resorts often fit both two-slot and earthed outlets, and will lend an adapter at the desk.
The neighbouring islands are all slightly different. Cuba runs 110 V at 60 Hz, the Dominican Republic 120 V at 60 Hz, and Barbados 115 V at 50 Hz - same plug shape, four combinations.
