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 [11] 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 [12] 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 onlyso always ahead with the carrier.
  • Small consumer portable chargers won't work with high powered items, although a rechargeable hair dryer [9] or gas hair straighteners [10] are available for travelling.

The sunlight in The Cayman Islands will be adequate enough to charge solar power bank [14] 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 [13] 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.

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.
