What adapter do I need for The Cayman Islands?

You need to bring a Type B plug adapter [3] to The Cayman Islands if your plug won't fit into a Cayman Islands power outlet.

The type of power adapter, converter or charger that's needed when visiting The Cayman Islands will all depend on the voltage and type of device that you're attempting to charge with a Cayman Islands power outlet. If you're unsure of what voltage your device can use then please read the section on how to find out the voltage of your device before going any further.

  • 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 can fit in a Cayman Islands power outlet then you can use it in The Cayman Islands without needing anything else.
  • If your device is 120 volts or is dual voltage but your plug doesn't fit in a Cayman Islands power outlet then you will need to bring a suitable plug adapter for The Cayman Islands such a Type B plug adapter [3]. A plug adapter for The Cayman Islands (or power adapter) is designed to change the shape of the plug on your device to fit into a plug outlet found in The Cayman Islands, but can't convert the voltage from 120 volts to use with another voltage.
  • If your device can't run on 120 volts and isn't dual voltage then you will also need a power converter for The Cayman Islands to convert the voltage from 120 volts to the correct voltage for your device. You'll still need to bring along a suitable plug adapter for The Cayman Islands if the power converter doesn't use the correct Type B plug adapter.
  • If you simply want to bring your USB devices such as tablets or cellphones then a USB travel power adapter will be more suited and it should be dual voltage, but ensure that you bring a USB travel adapter which has a Type B plug adapter otherwise you will also need to use a suitable plug adapter for The Cayman Islands.
  • An increase in use of a mobile phone during a vacation to The Cayman Islands will put an additional demand on the battery therefore you should pack a power bank [4] if you need to keep your phone or other USB powered devices charged whilst travelling to an unfamiliar country.

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

A power bank

Should I use a portable charger in The Cayman Islands?

While electrical cuts aren't common with power being available to the entire population, visitors are still advised to bring a portable charger to recharge mobile phones.

  • The dependence on mobile phones for some people is high and the thought of being offline can cause mild anxiety, particularly when being used when travelling to an unknown location. During a trip to The Cayman Islands increased use of mobile phones for storing calendars, taking photographs, social networks, getting directions and web browsing can syphon off power excessively. A flat mobile phone battery can possibly leave you in an unknown location without enough power to make emergency calls or being able to use sat nav to find your way back to accommodation or hotel. Bringing a portable charger [4] to The Cayman Islands alleviates those concerns as it means you can power up your mobile phone on the move.
  • Use at least a 10,000mAh power bank [4] which can store enough electricity to power over 3 full charges whilst a 20,000mAh portable charger [16] should keep a typical mobile phone powered for roughly seven days.
  • Providing that your laptop supports USB-C charging then bringing a portable charger for a laptop [17] marked with PD (power delivery) which supplies 20Wh or more can be used to recharge the laptop when travelling to The Cayman Islands. Be aware that some airlines don't let you take batteries on an aircraft with more than 100 Wh of power and must be kept in carry-on luggage only so always ahead with the carrier.
  • Small consumer portable chargers won't work with high powered items, although a rechargeable hair dryer [14] or gas hair straighteners [15] are available for travelling.
Will a solar charger work in The Cayman Islands?

Solar backpacks are ideal in hot countries

Will a solar charger work in The Cayman Islands?

The sunlight in The Cayman Islands will be adequate enough to charge solar power bank [19] reliability, however it will need to be left in strong sunshine to provide suitable power for a single charge. This may prove inconvenient to constantly unpack a solar power bank and wait for it to recharge in sunny spells.

  • Instead, the bigger panels used on a solar backpack [18] will give the backpack the ability to generate more power within a shorter period of time, making them ideal for the weather in The Cayman Islands.
  • Phones that have been plugged directly into the USB charging port of a solar backpack should gradually top up the power during sunny spells in The Cayman Islands, but this could prove inconvenient to have it continually tethered in the bag if it is to be needed constantly. A solar powered backpack is continuously exposed to light therefore will be powering up a regular power bank throughout the day, unlike a handheld solar power bank which needs unpacking and facing the sunlight.
  • Even though the climate in The Cayman Islands is suitable, a bag should have a solar cell efficiency of at least 22%, can generate a minimum of 6 watts of power and can be used with a power bank of 10,000mAH or stronger.
  • Unlike normal firm solar cells, the durable and flexible solar cells used in solar powered bags are designed to survive bending and scratching. Solar bags come in backpack, rucksack and messenger styles which makes them ideal for domestic, work and travel.

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?

A small, cheap and lightweight power adapter (or plug adapter) changes the shape of the plug on your device to slot into a power outlet found in The Cayman Islands, but an expensive and bulkier power converter [20] will transform the voltage of 120 volts from a Cayman Islands power outlet to work with a non-120 volt device.

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 [10] 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 [10].
  • 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 [21].
  • 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.

  2. If the power converter doesn't include the correct shaped plug then it will also be necessary to plug in the power cord from the power converter into a power adapter for The Cayman Islands before plugging that into a Cayman Islands power outlet.
  3. Some power converters include the ability to perform both step up and step down voltage conversions, therefore it may be necessary to manually switch the converter to output the voltage from 220-240v.
  4. Plug your appliance into the converter and turn the power on, your 220-240 volt appliance can now be used with a 120 volt Cayman Islands power outlet.
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.

Key to electrical adapter comparison

  1. Compatible number of countries based on data from the International Electrotechnical Commission World Plugs page (cited November 2018).
  2. Assuming only a single plug adapter from the plug adapter set will be used at any one time in a compatible location.
  3. Depending on if the power strip supports voltage conversion for low wattage items. All travel power strips tested do not convert voltage for high wattage appliances.
  4. Including the device itself, any supplied plug heads and power cords.
  5. Some travel power strips featuring less AC outlets may be small and lightweight enough to be suitable for hand luggage.
  6. Number of items if bringing an entire set of plug adapters for use in multiple locations to cover all eventualities (unless bringing only the necessary single plug adapter).

How many electrical items are you packing for The Cayman Islands?

Family may need to recharge devices too

How many electrical items are you packing for The Cayman Islands?

  • Add up how many applicances and devices you want to pack for The Cayman Islands (including tablets, laptops, cell phones, hair straighteners or clothes irons).
    • Allow for more electrical items at a later date. Do you intend on buying a new laptop computer soon?
    • There are an increasing amount of smaller rechargeable devices such as electric shavers that use USB as their power charging source, the next time you replace a device it could need a USB adapter so check that your travel adapter has enough spare ports to power these as well.
  • Are you bringing children to The Cayman Islands who will need to recharge their phones?
What are the different types of devices do you want to use?

A travel shaver

What are the different types of devices do you want to use?

  • There are three types of electrical devices or appliances:
    • Low wattage electrical devices which plug into an electrical outlet - for example a laptop.
    • High wattage appliances that can be plugged into a power outlet - for example clothes irons or hair straighteners.
    • USB devices which plug into a USB port - for example phones and iPads.
  • Should you only need to take just USB powered devices then you'll find that a travel USB charger is ideal because you will only need to bring that single lightweight charger with your USB charging cables whilst leaving your domestic chargers at home.
  • Travel power strips are built for providing power and voltage conversion for many low wattage devices, but unsuitable for high wattage appliances which need voltage conversion.
How many Cayman Islands power outlets will be available?

How many power outlets will be available

How many Cayman Islands power outlets will be available?

  • Hotels in The Cayman Islands may only have one power outlet on the wall. This could present a problem if charging up batteries of multiple items such as cell phones, tablet computers and cameras overnight as you will only be able to charge one device at a time every few hours.
  • To recharge multiple devices simultaneously we recommend packing a USB wall charger or a travel power strip that can charge multiple USB ports and outlets.

Do your devices and appliances only work with 120 volt power outlets?

Will you only be planning on charging USB devices in The Cayman Islands?

Will you only need USB electronics

Will you only be planning on charging USB devices in The Cayman Islands?

What is your budget?

  • A basic power adapter starts at $7 which powers only one device from a Cayman Islands power outlet (provided that works with 120 volts or it is dual voltage) however investing in roughly $20 allows you to power more than one device at once and use them in various different countries.

Do you intend on visiting anywhere abroad in the future?

Do you plan on visiting countries other than The Cayman Islands?

  • A simple plug adapter only typically works in the one country, so if you are visiting more than a single country you'll need to bring additional power adapters which can in turn add to the number of adapters you have to pack.
  • However, travel USB wall chargers and universal travel adapters are made for going to multiple countries becuase of the inclusion of interchangeable heads.
Are you flying long haul to get to The Cayman Islands?

Using a phone in an airport

Are you flying long haul to get to The Cayman Islands?

  • With long journeys it's worth considering bringing an airport-friendly charger that works in different power outlet types, one which can be packed in carry-on luggage and can be used to quickly top up phones and tablets.
  • Not all airports and airlines actually have power outlets for travellers therefore we recommend using a battery portable charger [4] which will recharge on the move. When you land you could have to rely on your phone to make telephone calls, sending emails , using mapping to locate your hotel or reading an itinerary - it is recommended that your phone has enough battery power stored.

Will you always have reliable access to electrical power?

  • The voltage in The Cayman Islands is stable however if you need to go to other countries you might need an adapter which will protect your electrical appliances. Electricty in some countries might often fluctuate which could potentially cause damage to your devices, so it is advisable to use an adapter which has surge protection such as a travel power strip.
  • Be prepared for a power cut and countries with limited electricity by packing a solar backpack [18] and portable charger [4].
