Should I pack a power bank for Saint Helena?

It is always recommended to pack a power bank to recharge mobiles and other USB powered devices when travelling.

  • The dependence on smartphones for some people is high and the thought of being offline can cause mild anxiety, particularly when being used in an unknown location. During a trip increased use of smart phones for taking pictures, storing calendars, GPS, social networks and staying entertained will drain power more excessively than normal. Beyond just missed photo opportunities a flat mobile phone battery can potentially leave you without adequate power to make an emergency call or being able to use sat nav to get directions to your hotel.
  • Using a power bank [4] in Saint Helena lowers that risk as it allows you to keep your smart phone charged without using a St Helenian power outlet.
  • We recommend bringing at least a 10,000mAh power bank [4] which will store enough energy to power over three full cycles whilst a 20,000mAh portable charger [14] should keep a typical mobile phone powered for roughly seven days. A mAh value (milli ampere-hours) describes the capacity of the battery and gives an indication of the number of cycles the power bank can do.
  • Should you want to charge your laptop in Saint Helena and it it supports USB-C charging then bring a portable charger for a laptop [15] marked with PD (power delivery) and a model supplying 20 Wh or more.
  • Before travelling be aware that some airlines prohibit portable chargers on an aircraft that supply 100Wh of power or more and must not be left in checked-in luggage.
  • Normal consumer power banks won't work with high powered items that generate heat, although a rechargeable hair dryer [12] or gas hair straighteners [13] are designed for travelling.

Does a solar battery charger work in Saint Helena?

Solar backpacks are ideal for hot climates

Does a solar battery charger work in Saint Helena?

The climate in Saint Helena will be suitable enough to recharge solar power bank [17] reliability, but will need to be exposed to strong daylight to produce suitable energy for a single charge. This could prove inconvenient to constantly unpack a solar power bank then wait for it to recharge in sunny spells.

  • Instead, the bigger durable panels used on a solar backpack [16] will give the backpack the ability to generate more power within a shorter period of time, meaning they should perform well in Saint Helena.
  • Phones which are directly plugged into the USB charging port of a backpack should gradually recharge the battery during sunny periods in Saint Helena, however this might be inconvenient to have the phone constantly connected to the bag during the day should it be needed frequently. A solar powered bag is more often 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.
  • Although the climate in Saint Helena is suitable, a bag should ideally have a solar cell efficiency of 22% or greater, can generate a minimum of 6 watts of energy and includes a power bank of 10,000mAH or greater.
  • The flexible and durable solar panels used in solar powered bags are built to endure bending and scratches, unlike normal solid solar panels. They come in messenger, rucksack and backpack styles which makes them perfect for domestic, work and travel use.

Power converters for Saint Helena

What is a power converter for a St Helenian power outlet?

Power converters for Saint Helena allow travellers to use their 100, 110 or 120 volt electrical device with a 240 volt St Helenian 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?

An expensive and heavy power converter [18] transforms the voltage of 240 volts from a St Helenian power outlet to work with a non-240 volt device, however a more lightweight and cheaper power adapter (or plug adapter) changes the shape of the plug on your device to fit into a power outlet found in Saint Helena.

Do I need a power converter for Saint Helena?

When travelling to Saint Helena from another country check the device can be charged using 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 is incompatible with 240 volts. See our WikiConnections world power outlets guide to find out the voltage is used in your country.
  • You won't need a power converter if you already own either a single voltage appliance that works with 240 volts or one that is dual voltage.
  • Typically, electrical devices which are designed to use a lower voltage such as 120 volts and used in a 240 volt outlet run the potential risk of blowing a fuse, damage to your device or even an electrical fire hazard unless you use a step down power converter [10].
  • You won't need a converter if you wish to recharge a smaller electrical device such as a mobile phone as these are normally dual voltage and designed for international use, however please 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 [19].
  • Investing a smaller robust dual voltage travel appliance could be more practical and cost effective than investing in a heavier high wattage power converter in order to use your existing domestic appliance in Saint Helena.
  • Read these comprehensive guides on travelling with clothes irons, curling wands, hairdryers and flat irons with St Helenian power outlets which includes advice on some affordable dual voltage alternatives.

What is the difference between a converter and a transformer?

Voltage converter

What is the difference between a converter and a 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 St Helenian 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 Saint Helena before plugging that into a St Helenian 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 St Helenian power outlet.

Is my device single voltage or dual voltage?

The easiest method to tell if your appliance is either single voltage or dual voltage is to look for a sticker on the supplied power adapter or on the device itself, normally near to where the power cord sits. This location might vary depending on the make or model of your device, it could also state on the box.

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

  • Should you only have to take just USB powered devices then you'll find that a simple travel USB charger is ideal because you will only need to bring that single lightweight charger with your existing USB charging cables rather than having to pack lots of domestic chargers.
  • Travel power strips are made for powering and voltage conversion for multiple low wattage devices (such as cameras), however unsuitable for high wattage appliances (such as clothes irons) which require voltage conversion.

How many St Helenian power outlets will be available?

  • Your accommodation in Saint Helena might only have one power outlet on the wall, this will present an issue if recharging the batteries of more than one item overnight because you can only recharge a single device at a time then have to keep swapping.
  • To charge more than one device at the same time look to using either a travel power strip or USB wall charger that can power multiple USB ports or outlets.

Is Saint Helena the only place you'll be visiting?

  • A single power adapter will only work in the one country that it was built for, therefore if you are visiting more than a single country you'll need to carry 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.

Do you plan on visiting elsewhere in the future?

How much can you afford?

  • Cheap power adapters start from under £10 which powers a single device in only one location (providing that it is dual voltage or is compatible with 240 volts), but paying roughly £15-£20 will allow you to charge more than one device at once and be able to use them in multiple countries.

Are you flying long haul to travel to Saint Helena?

  • For much longer journeys consider bringing a convenient 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 planes and airports have power outlets for customers therefore we recommend packing a travel portable charger [4] for recharging on the go. After landing in Saint Helena you could need to use a cell phone to make a call, messenging, using sat nav or viewing itineraries; so make sure that your phone has ample battery power left.
