Should I bring a power bank to Tristan da Cunha?

A USB portable charger

Should I bring a power bank to Tristan da Cunha?

It is always recommended to pack a portable charger to recharge cell phones and other USB powered devices whilst travelling.

  • Whilst travelling increased use of mobile phones for taking photographs, storing itineraries, GPS, social networks and staying entertained can syphon off power towards the end of the day. Beyond the inconvenience of missing photograph opportunities a flat mobile phone battery can possibly leave you stranded without sufficient power to make an emergency call or being able to use a GPS app to find your way back to accommodation or hotel. Using a power bank [4] eases those concerns as it means you can power up your cell phone without needing a Tristanian power outlet.
  • A 10,000mAh power bank [4] will supply enough power to power over three full days of mobile phone use while a 20,000mAh portable charger [9] should keep a typical mobile phone powered for almost 7 days.
  • As long as your laptop uses a USB-C charging port then packing a portable charger for a laptop [10] marked with PD (power delivery) which supplies 20Wh or more can be used to recharge your laptop. Please note that some airlines don't allow you bring batteries on an aircraft that supply 100Wh of power or more and must not be kept in the hold.
  • Consumer portable chargers won't work with high powered items that generate heat, but a rechargeable hair dryer [7] or gas hair straighteners [8] can be used for travelling.
Will a solar charger work in Tristan da Cunha?

A solar backpack recharging

Will a solar charger work in Tristan da Cunha?

The climate in Tristan da Cunha might be suitable for a solar power bank [12] but is likely to take time to recharge. Because of the smaller surface area of the cells a solar power bank will need to be kept in powerful daylight for a long period of time to provide enough energy for a single charge, and this might prove difficult to repeatedly pack and unpack a solar power bank then wait whilst it recharges between cloud cover.

  • Instead, the bigger durable solar cells found on a solar backpack [11] give the bag the ability to generate more power within a faster period of time.
  • A phone that is directly plugged into the USB charging port of a backpack should trickle charge the battery during sunny periods in Tristan da Cunha, but might prove inconvenient to have a phone constantly tethered in the bag during the day should it be needed frequently. A power bank [4] plugged in a solar backpack can be constantly topped up inside the bag during sunlight, afterwards the phone can be recharged using the power bank at any time without sunshine.
  • A solar bag that is suitable for Tristan da Cunha should have a solar cell efficiency of 22% or more, can generate a minimum of 6 watts of power and includes a 10,000mAH power bank or greater.
  • Solar bags are available in backpack, messenger and rucksack styles making them ideal for travel, work and domestic use.
  • Unlike normal solid solar panels, the flexible and durable solar cells used in solar powered bags have been built to survive bending and scratches.

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

What is the difference between a power adapter and a power converter for Tristan da Cunha?

A small, cheap and lightweight power adapter (or plug adapter) will change the shape of the plug on your appliance to fit into a power outlet found in Tristan da Cunha, but a heavier and more expensive power converter [14] transforms a 240 volt Tristanian power outlet to work with a non-240 volt device.

Do I need a power converter for Tristan da Cunha?

When you are travelling to Tristan da Cunha from another region please ensure the device can be charged using a 240 volt power supply.

  • You will need a step down power converter [15] if you are travelling from a country that uses 100-120 volts and your device is incompatible with 240 volts. See the world power outlets guide to discover which voltage your country uses.
  • You don't need a power converter if you are already using either a 240 volt single voltage appliance or one that supports dual voltage.
  • Typically, electrical devices which are designed to use a lower voltage (for example 120 volts) and used in a 240 volt outlet run a risk of an electrical fire hazard, blowing a fuse or damage to your device unless you use a step down power converter [15].
  • You shouldn't need a power converter if you are attempting to recharge a smaller electrical device such as a tablet or cell phone as these are normally designed for international use and dual voltage, but please always check the device for dual voltage support first.
  • For powering high wattage appliances or generate heat (such as clothes irons and hair straighteners) then you will need to use a more expensive higher wattage heavy duty power converter [16].
  • Purchasing a smaller lightweight dual voltage travel appliance could be more practical and cost effective than carrying a much heavier power converter just to use your existing domestic appliance.
  • Read our guides on using clothes irons, curling wands, hair straighteners and blow dryers with a Tristanian power outlet , along with advice on affordable dual voltage alternatives.

Do I need a power converter for Tristan da Cunha if I'm visiting from the US?

What is the difference between a transformer and a power converter?

Voltage converter

What is the difference between a transformer and a power converter?

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 [15] to allow you to use a 110 or 120 volt appliance with a 240 volt Tristanian 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 Tristan da Cunha before plugging that into a Tristanian 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 Tristanian power outlet.

What voltage is used in Tristan da Cunha?

Tristan da Cunha uses 240 volts in their normal power outlets.

How can you tell if you have a dual voltage appliance?

Dual voltage hair straighteners

How can you tell if you have a dual voltage appliance?

The way to tell if your device is dual voltage is to look for numbers printed on the power plug or on the device itself, normally on the rear of the device or near to where the power cord goes. This location might depend on the make and model of your appliance and could also state in the instruction manual.

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