Electric power in Jamaica is almost the same as in the United States and Canada. In Jamaica it is 110 -120v at 50 hz (also called 'cycles'). In the US and Canada the power operates 60 hz so a clock or other electrical appliance that bases its operation on the frequency of the power supply will work but will probably not work properly (for example a clock will operate but will not keep the proper time). Other types of electrical equipment such as hair dryers, cell phone, battery charges, etc. will work properly, if a bit slower, even if they are designed for 60 hz power supplies.

Note: Some, but not all, electrical appliances will automatically switch between using 110V and 220V power and between using 50 hz and 60 hz power. See the name tag on the unit, the manufacturer provided instruction manual, or call the manufacturer of the appliance for details. The following photo shows the name tag of an item that works on all input voltages between 100V and 240V and will work in Jamaica.

 

Jamaica uses type A and B receptacles (the same as used in the United States and Canada). See the following for a description of these two receptacle types:

Visitors to Jamaica from some countries, such as the UK, will need to bring converters to match or change the voltage and/or the receptacles in Jamaica if they bring any electrical equipment. Travel shops, department stores, electrical goods shops, etc. in your home country carry the proper voltage converters and receptacle adapters. Some resorts, but not all, in Jamaica can loan visitors the required receptacle adapters and/or voltage converters (contact your resort for availability).

Note: If a voltage converter is needed for the use of electrical equipment from your country in Jamaica, check the name plate, instruction manual, or contact the manufacturer to determine the wattage of each piece of electrical equipment. You should purchase a voltage converter which is capable of converting at least the largest wattage value of the pieces of electrical equipment you are taking to Jamaica.

For example, for UK visitors this means that both a voltage converter (from 110V to 220V, aka a step up converter) and a receptacle adapter (from type A or B to type G) will be required for a equipment made to UK standards to work in Jamaica. In the UK try shops such as Dixons (with many shops on the high street, Heathrow terminals 1, 3, 4, and 5, or Gatwick North and South terminals) or Harrods (located in central London) for both receptacle adapters and voltage converters.

Note should also be made of the power outages which happen in Jamaica. Because power outages are more common in Jamaica than in some other countries, visitors are advised to bring a flashlight (also known as a torch in the UK) and a battery operated clock. Many resorts have their own generators so power outages, if they happen, are often only a few seconds long.
