The Caribbean

Is an electrical power outlet for the Caribbean the same as a Cayman Islands power outlet?

Various countries throughout The Caribbean use different voltages and power outlet types, a plug that could be used in The Cayman Islands might not function or fit in another island. When travelling to more than one island in The Caribbean you should either bring along a multiple power adapter travel set consisting of various types of power adapters, or a single international travel plug adapter as both these options ensure that you are covered for most different power outlet types that you might find on each island.

As all islands in The Caribbean use different standards of voltages and power outlet types you may find a plug that can be used in The Cayman Islands might not work correctly with an electrical outlet on another island. Before travelling check these pages for more instructions on what to expect for every island in the Caribbean: Anguilla, Antigua, Aruba, Bahamas, Barbados, Barbuda, British Virgin Islands, Cayman Islands, Cuba, Curacao, Dominican Republic, Dominica, Grenada, Grenadines, Guadeloupe, Haiti, Jamaica, Martinique, Montserrat, Nevis, Puerto Rico, Saint Kitts, Saint Lucia, Saint Vincent, Tobago, Trinidad and US Virgin Islands.   [9] [9] [12] [AD]

How do I use a 220 volt appliance in The Cayman Islands?

To use a 220V appliance in a Cayman Islands power outlet you will need to use a step up power converter.

Are power outlets common in The Cayman Islands?

The Cayman Islands has excellent access to electrical power throughout the country.

How reliable is the power grid in The Cayman Islands?

Though power outages are unpredictable, electricity in The Cayman Islands is classed as dependable and there is no pattern of regular power blackouts.

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 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 which can store enough electricity to power over 3 full charges whilst a 20,000mAh portable charger 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 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 or rechargeable cordless flat iron are available for travelling.    [4] [4] [13] [14] [15] [16] [AD]

Will a solar charger work in The Cayman Islands?

Solar backpacks are ideal for hot climates

Will a solar charger work in The Cayman Islands?

The sunlight in The Cayman Islands will be adequate enough to charge solar power bank 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 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.  [17] [18] [AD]

Unlike other chargers this means you can power more than one device at the same time without needing to buy seperate power adapters. Because you are only packing a single travel charger will keep the overall weight and size down, making it perfect to fold up and store in hand luggage as well as being convenient for recharging your devices at the airport or on a plane. Because of their flexibility these types of travel chargers can be used at home so when you’re not on holiday they can sit overnight charging multiple smartphones, tablets and e-readers with only a single power outlet.

We recommend searching for a versatile travel charger similar to this online. The travel adapter illustrated here is the 4 Port USB Wall Charger which has been successfully tested for charging multiple USB devices in numerous different countries on a daily basis. [7] [AD]

What USB charger do I need for The Cayman Islands?

Why use a travel USB charger for The Cayman Islands?

  • Typically travel USB chargers include multiple USB charger ports, meaning you should only need to bring a single charger to charge multiple devices. This reduces the size and weight of your baggage by only needing to pack a single USB wall charger rather than having to bring several power chargers along.
  • Most travel USB chargers will include swappable plug heads for different countries. This is perfect when travelling to multiple countries which will probably use a different standard to The Cayman Islands.
  • Good USB travel power chargers are compact, rugged and lightweight; perfect for the rigors of travel rather than risking packing a domestic charger which could be impossible to repair in The Cayman Islands.
  • USB chargers can accept both the 120 volts used in The Cayman Islands power outlets plus different voltage standards in other countries.
  • There is a possibility that hotels in The Cayman Islands only have a single wall outlet, by using a travel charger with multiple USB ports allows you to share the single power supply with family or other traveler rather than waiting to charge one device at a time.
  • Because of their flexible nature they take the uncertainty out of visiting an unknown destination as they are guaranteed to work practically anywhere on the planet.
  • Power outlets found in airports are often in short supply and the demand for charging multiple cell phones from other passengers before a flight can be high, so a USB travel charger with multiple ports and the capability to fast charge is ideal.
  • Some countries power grids are unstable, a good quality travel USB charger allows for unexpected fluctuations to prevent damage to any devices attached to it. Attempting to repair an overloaded smartphone in The Cayman Islands might prove to be difficult and expensive.
  • Higher priced USB chargers will also include power outlet strips to use multiple low wattage devices such as laptops, however these will be unsuitable for high wattage appliances such as hair dryers or clothes irons. Refer to our section on using travel appliances with a Cayman Islands power outlet for helpful guidelines on the best power adapter to use with a Cayman Islands power outlet for high powered devices.
  • Certain cell phones and tablets might pull more than the normal 500 milliamps produced from a standard 5 volt USB adapter to charge or provide fast charge. Quality USB travel chargers will support fast charging incase some of your devices need extra power.
  • Travel USB power chargers can also be useful when returning home by recharging multiple mobile phones and tablets every night using one power outlet. [7] [AD]

What is the best USB charger for The Cayman Islands?

A 4 port USB travel charger is the most compact option for travellers from any country wanting to recharge devices via USB, however for those also wishing to use their domestic plugs these power strips provide larger but more versatile solutions. All 3 power adapters offer surge protection which can be crucial for travellers to counties with unreliable or unstable power supplies. These power adapters come with interchangeable type C, I and G plugs covering both The Cayman Islands and over 150 countries around the world:

This versatile power strip is compatible with both American plugs and popular plug types A, D,E/F, G, H, I, L and N making it ideal for most travellers from around the world visiting The Cayman Islands. [7] [AD]

Power converters for The Cayman Islands

What does a power converter for The Cayman Islands do?

A power converter for The Cayman Islands will enable travellers to use their 220, 230 or 240 volt electrical appliance with a 120 volt Cayman Islands power outlet.

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 will transform the voltage of 120 volts from a Cayman Islands power outlet to work with a non-120 volt device. [19] [AD]

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 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 can be used with a 120 volt power outlet otherwise you will need a step up power converter.
  • 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.
  • For 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.
  • 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.  [10] [20] [AD]

How to convert 120 volts to 220 volts

  1. Use a step up power converter to allow you to use 220, 230 and 240 volt appliances with a 120 volt Cayman Islands power outlet.
  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. [10] [AD]
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 straighteners

What voltage is my device?

The best method to see if your device is dual or single voltage is to look for numbers printed on the existing charger or on the unit itself, typically near to where the power cord plugs into. The location might depend on the make or model of your unit and should also be written in the instruction manual.

  • Single voltage devices might say a specific number - such as 220V.
  • Single voltage devices could also have a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 100-120V.
  • Dual voltage devices will typically say a larger range separated with a slash - such as 110/240V.

    • Low wattage electronic devices which can be plugged into an electrical outlet - for example a laptop.
    • High wattage electrical appliances that plug into a power outlet - for example hair straighteners or clothes irons.
    • USB devices that can be plugged into a USB port - for example mobile phones.
  • Should you only want to take just USB powered devices you'll find that a simple travel USB charger is ideal as you will only have to bring that single compact charger with your charging cables and leave your domestic chargers at home.
  • A travel power strip is designed for providing power and converting voltage for many low wattage devices of any voltage, however won't work with high wattage appliances that need voltage conversion and could potentially damage the power strip.

What is your budget?

  • A basic power adapter can power only one device from a Cayman Islands power outlet (providing that works with 120 volts or is dual voltage), however investing in a little more means you can power multiple devices at once and bring them to 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 perfect for travelling to multiple countries due to the inclusion of interchangeable heads.

Using a phone in the 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 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. [4] [AD]

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 and portable charger.  [4] [4] [17] [AD]
