Cayman Islands power outlet

What adapter do I need for The Cayman Islands?

The type of plug adapter, converter or charger that's needed when visiting The Cayman Islands all depend on the voltage and type of device that you're trying to power with a Cayman Islands power outlet. If you don't know what voltage your device can use then read the section about how to tell the voltage of your device first.

  • If you are from America and travelling to The Cayman Islands you will not need a power converter or a plug adapter. One suggestion however is to pack a multiple USB travel power adapter as it will allow you to power more than one device with only a single charger.
  • If your device is 120 volts or is dual voltage and the plug fits in a Cayman Islands power outlet then it will work in The Cayman Islands without needing anything else.
  • If your device can run on 120 volts or is dual voltage but your plug won't fit in a Cayman Islands power outlet then you will need a suitable plug adapter for The Cayman Islands such a Type B plug adapter [3]. Please Note that a plug adapter for The Cayman Islands (or power adapter) is designed to change the actual shape of the plug on your device to fit into a plug outlet found in The Cayman Islands, but doesn't convert the voltage from 120 volts to another voltage.
  • If your device is unable to use 120 volts and isn't dual voltage you will also need a power converter for The Cayman Islands to convert the voltage from 120 volts to the correct voltage on your device. You will still need to use a suitable plug adapter for The Cayman Islands if the power converter doesn't include the correct Type B plug adapter.
  • If you only want to power one or more USB devices such as cell phones or tablets then a USB travel power adapter is suitable and it should be dual voltage, however ensure that you bring a USB travel adapter which includes a Type B plug adapter otherwise you will still need to pack a suitable plug adapter for The Cayman Islands.

Warning: If your device won't handle the 120 volts used in The Cayman Islands you run the risk of an electrical fire hazard, blowing a fuse or damage to your device. Prior to using your device in The Cayman Islands check the instruction manual first to ensure safe operation.

Background

Also known as: electrical converter, electrical transformer, voltage converter, power transformer or voltage transformer.

What is the difference between a power converter and a plug adapter for The Cayman Islands?

An expensive and bulky power converter [10] will transform the voltage of 120 volts from a Cayman Islands power outlet to work with a non-120 volt appliance, whereas a more lightweight and smaller power adapter [9] (or plug adapter) will change the shape of the plug on your device to slot into a power outlet in The Cayman Islands.

Do I need a power converter for The Cayman Islands?

When travelling to The Cayman Islands from another country check your device can be charged using a 120 volt power supply.

  • You need a step up power converter [11] if you are travelling to The Cayman Islands from a country that uses 220-240 volts and your appliance or device won't support 120 volts. See the list of world power outlets page to find out which voltage your country uses.
  • You shouldn't need a power converter if you are already using either a 120 volt device or one that supports dual voltage.
  • Normally electrical devices which come from a different country which use a higher voltage (such as 230 volts) and used with 120 volts can take longer to charge or won't turn on. If your device charges slowly or does not power up when travelling to The Cayman Islands from a different region check that it is compatible with a 120 volt power outlet or you will need a step up power converter [11].
  • You won't need a power converter if you are attempting to charge a smaller electrical device such as a laptop as these are normally dual voltage and designed for international use, however you should always check the device for dual voltage support prior to your journey.
  • When powering high wattage appliances or generate heat (for example hair straighteners and clothes irons) then you will need to use a much larger higher wattage heavy duty power converter [12].
  • It should be more cost effective to purchase a smaller robust dual voltage travel appliance than paying for a heavier high wattage power converter to The Cayman Islands just to use your existing domestic appliance.
  • Read our comprehensive travel guides on using clothes irons, curling wands, hair straighteners and blow dryers in The Cayman Islands which includes recommendations for affordable dual voltage alternatives.

What is the difference between a power converter and a power transformer?

Voltage converter

What is the difference between a power converter and a power transformer?

Converters and transformers are both used to change one voltage to another, but this ambiguity can cause confusion as their purposes are different:

  • Power converters are designed for simple electrical appliances which typically generate heat or use motors such as clothes irons, shavers or hair dryers. Transformers are designed for more complex electronic items such as televisions or games consoles.
  • Buying a power converter is cheaper than buying a power transformer.
  • Power transformers are larger and heavier making them more suited for permanent residential use; for example an expat wishing to use an imported television would need to use a transformer for this purpose.
  • Power converters are more suitable for travellers wishing to bring domestic appliances abroad such as hair dryers or flat irons. However, it is more practical and cost effective to purchase a dual voltage appliance designed for travel rather than a heavier power converter.
  • Power converters are suitable for 2 pin ungrounded appliances, it could be harder to find a converter if you want to use a grounded 3 pin appliance.
  • Transformers can be used constantly however it is recommended that converters are used for no longer than a couple of hours at a time.
  • Shops may sell transformers under the name of converters, for the purposes this guide we will be referring to both converters and transformers as converters.
What voltage is my device?

Single voltage hair dryer

What voltage is my device?

The easiest way to tell if your appliance is dual voltage is to look for a sticker on the supplied power adapter or on the device itself, normally near to where the power cord sits. This location might vary depending on the make or model of your appliance, it should also state on the box.

  • Single voltage devices might have a specific number - such as 240V.
  • Single voltage devices could also say a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 220-240V.
  • Dual voltage devices will normally say a larger voltage range separated with a slash - such as 110/240V.
