Should I bring a portable charger to The Ascension Islands?

It is always recommended to bring a power bank to recharge cell phones whilst travelling.

  • The dependence on mobile phones for some is high and being without a mobile can leave them anxious, particularly when being relied upon when travelling. Whilst travelling increased reliance on mobile phones for taking photos, storing calendars, getting directions, social networks and playing games will drain the power before the end of the day. A flat cell phone battery could possibly leave you without adequate power to make an emergency call or being able to use a satellite navigation app to find your way back to accommodation or hotel. Using a portable charger [4] eases those concerns as it means you can recharge your cell phone on the go.
  • Use at least a 10,000mAh portable charger [4] which can store enough power to cover around three full charges whilst a 20,000mAh power bank [14] should keep an average smart phone powered for roughly a week depending on the usage and model of the phone.
  • If your laptop has a USB-C charging port then a portable charger for a laptop [15] marked with PD (power delivery) that supplies 20Wh or more can be used to extend the battery life of that laptop in The Ascension Islands. Before travelling please note that some airlines don't allow you take power banks on an aircraft with more than 100Wh of power and must be kept in hand luggage only.
  • Average consumer portable chargers aren't designed for use with high powered items, although a rechargeable hair dryer [12] or gas hair straighteners [13] can be used for travelling.

Does a solar battery charger work in The Ascension Islands?

Solar backpacks are ideal in hot weather

Does a solar battery charger work in The Ascension Islands?

The sunlight in The Ascension Islands will be adequate enough to recharge solar power bank [17] reliability, but will need to be left in strong daylight in order to produce adequate energy for a single charge. It could prove inconvenient to continually unpack a solar power bank then wait for it to recharge in sunny spells.

  • Instead, the much larger solar panels used on a solar backpack [16] will give the bag the ability to create more electricity within a faster period of time and could also generate power when cloudy, meaning they should perform well in The Ascension Islands.
  • A phone which has been plugged directly into the USB port of a backpack can trickle charge the power during sunny periods in The Ascension Islands, however could prove inconvenient to have the phone continually connected in the bag if it is to be needed frequently. A battery power bank [4] plugged in a solar backpack can be constantly recharged inside the bag during the day, afterwards the phone can be recharged using the power bank at any time without sunshine.
  • Even though the sunlight in The Ascension Islands is strong, a bag should have a solar cell efficiency of at least 22%, can generate at least 6 watts of energy and be used with a compatible power bank of 10,000mAH or greater. Unlike regular solid solar cells, the durable and flexible solar panels used in solar powered bags have been made to survive bending and scratching. They are available in backpack, rucksack and messenger styles making them perfect for travel, domestic and work.

Do I need a power converter for The Ascension Islands?

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

  • A step down power converter [10] is needed if you are travelling to The Ascension Islands from a country that uses 100-120 volts and your appliance isn't compatible with 240 volts. Read the WikiConnections list of world power outlets guide to see the voltage your country uses.
  • You shouldn't need a power converter if you already use either a single voltage device that works with 240 volts or one that supports dual voltage.
  • Devices which are designed to use a lower voltage (such as 120 volts) and then used in a 240 volt outlet run the potential risk of damage to your device, an electrical fire hazard or a blown fuse unless you use a step down power converter [10].
  • You won't need a power converter if you wish to power a smaller electrical device such as a tablet or mobile phone as these are typically support dual voltage and designed for international use, however you should always check the device for dual voltage support first.
  • For supplying power to high wattage appliances or generate heat (for example hair straighteners and curling irons) then you will need to use a bulkier higher wattage heavy duty power converter [19].
  • Investing a smaller lightweight dual voltage travel appliance should be more cost effective and practical than bringing a heavier power converter in order to use your existing domestic appliance.

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.

    • High wattage electrical appliances that can be plugged into an electrical outlet - for example hair dryers or clothes irons.
    • USB powered devices which connect to a USB port - for example phones.
  • Should you only intend to take just USB powered devices to The Ascension Islands you'll find that a simple travel USB charger is perfect because you'll only have to bring that single lightweight charger along with appropriate USB charging cables whilst leaving your domestic chargers at home.
  • Travel power strips are made for powering and converting voltage for multiple low wattage devices of any voltage (such as a laptop), but won't work with high wattage appliances which require voltage conversion.

Do your devices work with a 240 volt power outlet?

Will your trip include visits to countries other than The Ascension Islands?

  • Single plug adapters will typically only work in a single country that they are made for, so if you plan on visiting multiple countries then you'll need to carry additional plug adapters which in turn adds to the weight you'll have to pack.
  • However, universal travel adapters and travel USB wall chargers are designed for visiting multiple countries due to their interchangeable head system.
