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 [12] 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 [11] 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.

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.

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
