The frequency of the alternating current in a Cook Islands power outlet is 50Hz.

Is the voltage in The Cook Islands the same as in the US?

The voltage which comes from a Cook Islands power outlet is 240 volts, but Americans use 120 volts. If your American appliance or charger isn't dual voltage then you will need use a power converter for a Cook Islands power outlet which allows a 120 volt US appliance to work with a 220-240 volt outlet.

How do I use a 110 volt appliance in The Cook Islands?

A step down power converter will allow you to use either a 110V or 120V appliance in a Cook Islands power outlet.

Should I pack a portable charger for The Cook Islands?

It is always recommended to bring a portable charger to recharge their cell phone and other devices when travelling.

  • During a trip to The Cook Islands increased use of cell phones for taking photos, storing itineraries, social networks, sat nav and staying entertained could syphon off power more excessively than normal. Beyond the simple missing photograph opportunities a flat cell phone battery could possibly leave you in an unknown location without enough power to make an emergency call or being able to use a satellite navigation app to return to your hotel or accommodation. Using a portable charger [4] eases those concerns as it allows you to recharge your cell phone on the go.
  • Bring at least a 10,000mAh portable charger [4] which can supply enough electricity to cover over 3 full days of mobile phone use and a 20,000mAh portable charger [14] should keep a typical mobile phone charged for almost a week.
  • If you need to charge your laptop with a portable charger in The Cook Islands and your laptop it supports USB-C charging then pack a portable charger for a laptop [15] marked with PD (power delivery) which supplies at least 20 Wh. Before travelling please note that some airlines won't allow you take power banks on an aircraft with more than 100Wh of power and must be kept in hand luggage only.
  • Typical consumer portable chargers aren't designed for high powered items, but a rechargeable hair dryer [12] or gas hair straighteners [13] are available for travelling.

Do solar battery chargers work in The Cook Islands?

Solar backpacks are ideal for hot climates

Do solar battery chargers work in The Cook Islands?

The climate in The Cook Islands will be adequate enough to charge solar power bank [17] dependably, but needs to be exposed to strong sunshine in order to provide enough energy for a single charge. This may prove inconvenient to continually unpack a solar power bank then wait whilst it recharges in sunny spells.

  • Instead, the larger solar panels found on a solar backpack [16] will give the bag the ability to create more electricity within a faster period of time, meaning they should perform well in The Cook Islands.
  • Phones that are directly plugged into the USB port of a solar backpack will gradually top up the battery during sunny periods in The Cook Islands, but this could be inconvenient to have it continuously tethered to the bag during the day should it be used constantly. Unlike a handheld solar power bank which requires unpacking facing the sunlight, a solar bag is more often exposed to light so can be recharging a regular power bank [4] during the day.
  • Even though the sunlight in The Cook Islands is strong, a bag should have a solar cell efficiency of at least 22%, can generate at least 6 watts of power and be used with a 10,000mAH power bank or greater. Unlike normal firm solar cells, the flexible and durable cells used in solar powered bags have been designed to endure scratching and bending. Solar bags are found in rucksack, backpack and messenger styles which makes them ideal for travel, work and domestic use.

What is a USB travel power charger?

A USB travel charger is a dual voltage charger with interchangeable plugs and multiple USB ports, suitable for charging multiple USB powered devices when travelling abroad.

Why use a travel USB charger for The Cook Islands?

  • Typically travel USB chargers include multiple USB charger ports, this means that you now only need to bring one charger to charge all your devices. It helps reduce the size and weight of your baggage by only packing one USB wall charger rather than needing to bring numerous individual USB chargers along.
  • Most travel USB power chargers include swappable plug heads for various regions thereby making them ideal when travelling to other countries across Oceania which are likely to use different standards to The Cook Islands.
  • A good USB charger is lightweight, compact and rugged - perfect for rigors of travel rather than risking bringing along a domestic charger which could be impossible to repair in The Cook Islands.
  • USB travel chargers will accept the 240 volts used in The Cook Islands power outlets plus other voltage standards in other countries.
  • There is a possibility that hotel bedrooms or accommodation in The Cook Islands only have a single wall outlet, by bringing a travel charger with multiple USB ports means you can share the single wall outlet with family or other traveler instead of having to wait to recharge each device one by one.
  • Due to their flexible nature a travel USB charger takes the uncertainty out of travelling to any unknown destination as they are guaranteed to work practically anywhere around the world.
  • Power outlets found in airports are often scarce and the demand for charging multiple devices from other passengers during departure can be high, so a USB travel charger with multiple ports and the ability to charge quickly is perect.
  • Some countries power grids are unstable, a good quality travel charger allows for unexpected surges and prevents damage to any devices attached to it. Trying to repair an overloaded mobile phone or tablet in The Cook Islands might prove to be inconvenient and expensive.
  • Premium USB chargers should also include power outlet strips to allow you to plug in low wattage devices such as laptops, but note these are unsuitable for high powered appliances such as hair dryers or clothes irons. Read our section on using travel appliances with a Cook Islands power outlet for advice on the most suitable power adapter to use with a Cook Islands power outlet for high powered appliances.
  • Certain tablets and cell phones could pull more than the normal 500 mA (milliamps) supplied by a normal 5 volt USB power adapter to charge or provide fast charge. Ensure that the USB power adapter can support fast charging should some of your devices need additional power.
  • Travel USB chargers can still be useful when returning home by charging multiple cell phones every night using a single power outlet.

Power converters for The Cook Islands

What is a power converter for a Cook Islands power outlet?

A power converter for The Cook Islands allows you to use a 100, 110 or 120 volt electric appliance with a 240 volt Cook Islands power outlet.

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

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

A small, cheap and lightweight power adapter (or plug adapter) changes the shape of the plug on your device to fit into a power outlet in The Cook Islands, however a heavier and more expensive power converter [18] converts a 240 volt Cook Islands power outlet to work with a non-240 volt appliance.

Do I need a power converter for The Cook Islands?

If you are visiting The Cook Islands from a different region please check the device will accept a 240 volt power supply.

  • A step down power converter [10] is needed if you are travelling from a country that uses 100-120 volts and your appliance isn't compatible with 240 volts. Read the WikiConnections world power outlets guide to see which voltage your country uses.
  • You shouldn't need a power converter if you already own either a 240 volt single voltage appliance or one that is dual voltage.
  • Normally electrical devices which are designed to work with a lower voltage such as 110 volts and used with 240 volts run a risk of an electrical fire hazard, a blown fuse or damage to your device.
  • You shouldn't need a converter if you wish to recharge a smaller electrical device such as a cell phone as these are normally designed for international use and support dual voltage, however you should always always check the device for dual voltage support prior to your journey.
  • When powering appliances which draw more power or generate heat (such as curling irons and hair dryers) then you will need to use a much larger higher wattage heavy duty power converter [19] which allows it to be used with a 240 volt Cook Islands power outlet.
  • Investing a smaller robust dual voltage travel appliance could be more cost effective and practical than carrying a much heavier power converter in order to use your existing domestic appliance.
  • For more information read our comprehensive travel guides on travelling with curling wands, clothes irons, blow dryers and flat irons in Cook Islands power outlets , along with guides for affordable dual voltage alternatives.

Will I need a power converter for The Cook Islands if I'm from America?

The voltage from a wall outlet in The Cook Islands is different to an American supply so you will need to bring a step down power converter if your appliance or charger isn't dual voltage.

What kind of converter do I need for The Cook Islands?

You need to buy a step down power converter [10] in order to use any 100, 110 or 120 volt appliance in The Cook Islands.

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.

How to convert 240 volts to 110 volts

  1. Use a step down power converter [10] to allow you to use a 110 or 120 volt appliance with a 240 volt Cook 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 Cook Islands before plugging that into a Cook 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 to the 110-120 volt range.
  4. Plug your appliance into the converter and turn the power on, your 110-120 volt appliance can now be used with a 240 volt Cook Islands power outlet.

What voltage does The Cook Islands use?

The Cook Islands uses 240 volts in their normal power outlets.

How to tell the voltage of your device

Single voltage hair straighteners

How to tell the voltage of your device

One method to tell if your appliance is dual voltage is to check for a sticker on the power adapter or on the appliance itself, typically near to where the power cord goes. This location will depend on the make or model of your appliance, it could also be written on the box or in the instruction manual.

  • Single voltage devices could have a specific number - such as 110V.
  • 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 say a large range separated with a slash - such as 110/240V.

How many devices will you be packing

How many devices will you be bringing to The Cook Islands?

  • Try adding up how many electrical items you intend to bring to The Cook Islands (for example laptops, phones, tablets, eReaders, clothes irons or hair dryers).
    • Remember to take into account that you might own more electrical items in the future. Are you thinking about purchasing a new laptop computer soon?
    • There is an increasing amount of USB powered rechargeable devices such as electric shavers which use USB charging for a power source, the if you buy a new device it might use a USB power adapter so ensure your travel adapter has enough spare ports for these additional items too.
  • Are you bringing children along who might need to charge their iPads?

Make a list of items you need

What different types of electrical devices do you want to use with a Cook Islands power outlet?

  • There are three different types of electrical devices or appliances:
    • Low wattage electrical items that can be plugged into an electrical outlet - for example cameras or laptops.
    • High wattage electrical appliances which plug into a power outlet - for example clothes irons or hair straighteners.
    • USB powered devices that can be plugged into a USB port - for example phones.
  • Should you only have to take just USB powered devices to The Cook Islands then a simple travel USB charger is perfect because you'll only have to bring that single lightweight charger whilst leaving your domestic chargers at home.
  • Travel power strips are ideal for powering and converting voltage for many low wattage devices (such as cameras), however won't work with high wattage appliances (such as hair irons) that require voltage conversion and could potentially damage it.
Are you only charging USB devices?

Will your devices and appliances work with a 240 volt power outlet?

Is The Cook Islands the only location you intend on visiting?

  • A single plug adapter only operates in the one country which it is made for, so if you plan on visiting multiple countries then you may need to pack additional plug adapters which in turn adds to the weight you'll have to bring.
  • However, universal travel adapters and travel USB wall chargers are designed for visiting multiple countries due to their interchangeable head system.
How many Cook Islands power outlets are available?

How many power outlets will be available

How many Cook Islands power outlets are available?

  • A hotel may only have a single power outlet on the wall. This will be an inconvenience when charging up the batteries of multiple electronic items such as tablets, mobile phones or laptops overnight as you'll only be able to charge a single device at a time.
  • Should you want to charge more than one device simultaneously then we suggest using either a USB wall charger or a travel power strip which can charge multiple USB ports and power outlets.

Do you plan to visit elsewhere in the future?

What is your budget?

  • A basic power adapter starts at under $10 USD (under £15 GBP / under C$45) which will charge only a single device in The Cook Islands (providing that works with 240 volts or is dual voltage), but investing in roughly between $15 to $20 USD (£15-£20 GBP / C$25-C$30) means you can power more than one device at once and use them in various countries.

Do you still need use your charger when returning home?

Do you intend to bring hand luggage to The Cook Islands?

Are you bringing just hand baggage

Do you intend to bring hand luggage to The Cook Islands?

Will it take you a long time to get to The Cook Islands?

Arriving at an airport

Will it take you a long time to get to The Cook Islands?

  • For much longer journeys consider a convenient airport-friendly charger that can be used with different power outlet types, one that is small enough to pack in carry-on luggage and can be used to quickly charge tablets and phones.
  • Not all airlines and airports actually have power outlets so consider using a travel portable charger [4] which will recharge on the go. After arriving you could have to use a cell phone for making calls, using sat nav to locate your hotel or recalling itineraries; therefore it is recommended that your phone will have ample charge left.
