Access to electrical power in The United Kingdom is excellent which spans the entire population.

Should I pack a portable charger for The United Kingdom?

A portable charger

Should I pack a portable charger for The United Kingdom?

Even though electrical failures aren't common and electricity is available to the entire population, travellers should still bring a power bank to recharge mobile phones and other USB powered devices.

  • With many the thought of being without their phone can cause mild anxiety, especially when being used when travelling to an unknown location. During a trip increased use of smart phones for taking pictures, storing calendars, GPS, social network sharing and web browsing could drain batteries towards the end of the day. A flat cell phone battery could possibly leave you stranded without adequate power to make emergency calls or being able to use satellite navigation to find your way back to hotel or accommodation. Using a portable charger alleviates those concerns as it means you can keep your cell phone fully powered without using a wall charger.
  • We recommend using at least a 10,000mAh portable charger which will supply enough energy to cover over three full charging cycles while a 20,000mAh portable charger should keep an average mobile phone powered for roughly seven days. The mAh value (milli ampere-hours) describes the capacity of the battery and gives an indication of the number of recharges the power bank can achieve, so a higher value will be better for travellers.
  • As long as your laptop supports USB-C charging then a portable charger for a laptop marked with PD (power delivery) that supplies 20Wh or more can be used to recharge that laptop when travelling to The United Kingdom. Be aware that some airlines won't let you bring power banks on an aircraft that supply 100 Wh of power or more and must not be left in checked-in luggage so please check ahead with the airline first.
  • Consumer power banks aren't designed for high powered items that generate heat, but a rechargeable hair dryer or rechargeable cordless flat iron are designed for travelling.    [10] [10] [18] [19] [20] [21] [AD]
How well do solar powered chargers work in The United Kingdom?

A solar backpack recharging in the sun

How well do solar powered chargers work in The United Kingdom?

The daylight in The United Kingdom might be suitable for a solar power bank, however it is likely to take time to charge. Due to the small surface area a solar power bank will need to be left in strong daylight for an extended period of time to produce enough power for a single charge, and this might prove difficult to constantly pack and unpack a solar power bank and wait for it to recharge between cloud cover.

  • Instead, the larger solar cells used on a solar backpack give the bag the ability to create more electricity within a faster period of time.
  • A phone that has been directly plugged into the USB port of a backpack can trickle charge the battery during sunny spells in The United Kingdom, however might prove inconvenient to have it continuously tethered in the bag during the day if it is to be used constantly. A solar powered bag is more often exposed to light therefore could be charging a regular power bank throughout the day, unlike a small solar power bank which needs unpacking and facing the sunlight.
  • A solar bag that is suitable for The United Kingdom needs to have a solar cell efficiency of 22% or more, be able to generate at least 6 watts of power and be used with a 10,000mAH power bank or stronger.
  • They are available in rucksack, backpack and messenger styles which makes them ideal for work, travel and domestic use.
  • The flexible and durable solar cells used in solar powered bags are built to endure bending and scratches, unlike normal solid solar panels.  [10] [22] [23] [AD]

The United Kingdom chargers

What is a USB travel power charger?

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.

What USB charger do I need for The United Kingdom?

When you are travelling to more than one country and bringing more than just one device the best international travel charger for The United Kingdom is a multiple USB adapter which includes compatible plugs like a 4 port USB travel charger. As these types of chargers are supplied with interchangeable pins and handle from 100 volts - 240 volts will mean you can travel to over 100 countries around the world simply by changing the supplied plugs. If your model of device supports Fast Charge then you will benefit from faster recharging times with one of these travel adapters plus additional compatibility with certain power demanding devices.

Unlike other travel chargers this means you can power more than one device at the same time without needing to buy seperate power adapters on your UK trip. By only bringing a single international USB travel charger will keep the size down, making it ideal to store in hand baggage whilst travelling as well as being on hand for charging your devices at the airport or on a flight. Because of their flexibility these types of travel chargers can be used back at home so when you’re not travelling they can be used overnight charging multiple phones and tablets without needing an additional plug socket.

We suggest buying an adaptable travel adapter like this online. The travel adapter illustrated here is the 4 Port USB Wall Charger which has been successfully tested for recharging multiple USB devices in numerous countries on a daily basis. [2] [AD]

What USB charger do I need for The United Kingdom?

Why use a travel USB charger for The United Kingdom?

  • Most travel USB chargers include multiple USB charger ports, this means that you now only need to bring one charger to charge multiple devices. Instead of bringing 4 separate power chargers you only need to pack a single 4 port USB wall charger to power up to 4 individual devices, thereby reducing the weight and size of your baggage.
  • Most travel USB chargers will include swappable plug heads for different countries. This is suitable when travelling across different countries which will probably use different standards to The United Kingdom.
  • A good USB power charger is lightweight, compact and rugged - ideal for the rigors of travel instead of than risking bringing a domestic charger which could be impossible to replace or repair in The United Kingdom.
  • USB chargers will accept both the 230 volts used in The United Kingdom power outlets and different voltage standards in other countries.
  • There is a possibility that hotels in The United Kingdom might only have a single wall outlet, by bringing a travel charger with multiple USB ports allows you to share out the single power supply with all your devices instead of having to wait to recharge each device one by one.
  • Because of their versatile nature a travel USB charger takes the worry out of travelling to any unknown country as they are guaranteed to work practically anywhere in the world.
  • Power outlets in airports can be scarce and demand for charging multiple cell phones and tablets from other passengers during departure can be high, so a USB charger with multiple ports and the capability to fast charge is ideal.
  • Some countries power grids are unstable, a good quality travel USB charger allows for unexpected fluctuations and will prevent damage to any devices attached to it. Trying to repair an overloaded smartphone or tablet in The United Kingdom could prove to be problematic and expensive.
  • Premium USB travel chargers should also feature a power outlet strip to allow you to use low powered domestic appliances such as laptops, but please be aware these will be unsuitable for high powered domestic such as hair dryers or clothes irons. Read our section on using travel appliances with a UK power outlet for helpful advice on the best power adapter to use with a UK power outlet for high powered devices.
  • Certain tablets and cellphones might require more than the normal 500 mA 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 require extra power.
  • Travel USB power chargers can still be useful back at home by recharging multiple mobile phones and tablets every day using a single power outlet. [2] [AD]

What is the best USB charger for The United Kingdom?

A 4 port USB travel charger is the most compact option for travellers from any country wanting to recharge devices via USB, however for those also wanting to use their domestic plugs these power converters provide larger but more versatile solutions. All 3 power converters offer surge protection which is useful when visiting counties with unstable power grids to prevent damage to any connected appliances from voltage spikes. These travel converters come supplied with interchangeable type C, I and G plugs covering Europe, North America, Australia, United Kingdom, Japan, China and over 150 destinations:

  • BESTEK Portable International Travel Voltage Converter - The BESTEK travel adaptor has 4 USB charging ports with 3 AC power outlets and is the most popular compact power converter for travellers originating from North America going to The United Kingdom using type B American plug sockets.
  • ORICO Traveling Outlet Surge Protector Power Strip - Similarly having 4 USB ports but only 2 AC power outlets the travel adapter from Orico is also aimed at travellers originating from North America using type B plugs and gives almost the same set of features as the BESTEK with just 1 less AC outlet for almost half price.

Power converters for The United Kingdom

What does a power converter for a UK power outlet do?

Power converters enable you to use a 100-120 volt electric appliance with a 230 volt UK 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?

A lightweight, cheap and small power adapter (or plug adapter) changes the shape of the plug on your appliance to fit into a power outlet in The United Kingdom, whereas a more expensive and heavier power converter transforms a 230 volt UK power outlet to work with a non-230 volt appliance. [15] [AD]

Do I need a power converter for The United Kingdom?

When visiting The United Kingdom from another country check your device can be charged using a 230 volt power supply.

  • A step down power converter is needed if you are travelling from a country that uses 100-120 volts and your appliance is incompatible with 230 volts. See our WikiConnections world power outlets guide to find out the voltage your country uses.
  • You won't need a power converter if you already use either a single voltage device that works with 230 volts or one that supports dual voltage.
  • Typically, devices designed to work with a lower voltage (such as 110 volts) and used with 230 volts run the risk of blowing a fuse, damage to your device or even an electrical fire hazard.
  • You shouldn't need a power converter if you wish to power a smaller electrical device such as a tablet or cell phone as these are typically designed for international use and dual voltage, but you should always always check the device for dual voltage support first.
  • If supplying power to high wattage appliances or generate heat (such as clothes irons and hair straighteners) then you will need to use a much larger higher wattage heavy duty power converter.
  • 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.
  • Read these comprehensive guides on travelling with curling irons, clothes irons, flat irons and hairdryers with UK power outlets , along with guides for some affordable dual voltage alternatives.  [6] [15] [AD]

What converter do I need for The United Kingdom?

In order to use any 100, 110 or 120 volt appliance in The United Kingdom you will need to buy a step down power converter[15] [AD]

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

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 230 volts to 110 volts

  1. Use a step down power converter to allow you to use a 110 or 120 volt appliance with a 230 volt UK 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 The United Kingdom before plugging that into a UK 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 230 volt UK power outlet. [15] [AD]

What voltage is used in The United Kingdom?

The United Kingdom uses 230 volts in their power outlets. [8]

What voltage is my appliance?

Single voltage hair straighteners

What voltage is my appliance?

One way to tell if a appliance is single or dual voltage is to check for a sticker on the charger, or on the unit itself, typically on the rear of the appliance or near to where the power cord plugs into. The location might depend on the make or model of your unit and should also state on the box.

  • Single voltage devices might have a specific number - such as 240V.
  • 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.

The type of power converter that is suitable for The United Kingdom depends on various requirements. Before choosing the right one to use we suggest reading through the following checklist:

How many electrical items are you packing for The United Kingdom?

How many devices are you packing

How many electrical items are you packing for The United Kingdom?

  • Count how many electrical items you intended on bringing with you to The United Kingdom (for example mobile phones, tablets, laptops, eReaders, curling irons and hair dryers).
    • Remember to allow for more devices at a later date. Are you thinking about buying a new tablet computer next year for example?
    • There are an increasing amount of smaller rechargeable devices such as electric shavers that use USB charging as a power charging source. The next time you buy a new device it could use a USB adapter so please ensure your travel adapter has enough spare ports for these also.
  • Will you also be travelling with family who might need to recharge their devices?
What different types of electrical devices do you want to charge?

What different types of electrical devices do you want to charge?

  • There are three types of electrical devices or appliances:
    • Low wattage electrical devices which plug into an electrical outlet - for example cameras or laptops.
    • High wattage appliances which can be plugged into a power outlet - for example hair dryers and curling irons.
    • USB powered electrical devices that charge using a USB port - for example mobile phones.
  • If you only want to bring along just USB powered devices you'll find that a simple travel USB charger is ideal because you will only have to bring that single lightweight charger with your existing USB charging cables.
  • Travel power strips are most suited for powering and voltage conversion for several low wattage devices (such as laptops), however won't work with high wattage appliances (such as hair straighteners) that require voltage conversion and could potentially overload the power strip.
Will you only be planning on charging USB devices in The United Kingdom?

Do your devices and appliances work with 230 volt power outlets?

How many UK power outlets will be available?

Are multiple wall outlets available

How many UK power outlets will be available?

  • Your accommodation in The United Kingdom might only have a single power outlet, this could be an issue when recharging batteries of multiple electronic devices such as cell phones, tablet computers and laptops overnight as you will only be able to recharge one device at a time every few hours.
  • Should you want to charge more than one device at the same time then we suggest bringing a travel power strip or travel USB wall charger which are capable of powering multiple USB ports or power outlets. [12] [AD]

Do you intend to visit anywhere abroad in the future?

Do you plan on visiting countries other than The United Kingdom?

How much can you afford to pay?

  • A basic power adapter can power a single device in only one location (providing that it is dual voltage or is compatible with 230 volts) but paying a small amount more will allow you to charge more than one device at once and you will be able to use them in multiple different countries.

Will you always have reliable access to electricity?

  • Electricty in The United Kingdom is stable but if you need to visit other countries you might need an electrical adapter to protect your appliances. Power might occasionally fluctuate in some countries and this might cause damage to your devices, so you will need to look for an adapter which offers built in surge protection such as a travel power strip.
  • Be prepared for a power cut and countries with limited electricity by using a portable charger and a solar backpack.  [10] [10] [22] [AD]

Would you like to use your charger when returning home?

Are you only bringing hand luggage to The United Kingdom?

Are you bringing just hand baggage

Will it take you a long time to get to The United Kingdom?

How long will it take to travel

Will it take you a long time to get to The United Kingdom?

  • If you are embarking on an extended journey to get to The United Kingdom consider an airport-suitable power charger that can be used with multiple outlet types, one that is light enough to pack in carry-on luggage and can quickly power tablets and phones.
  • Not all airports and airlines actually have power outlets for customers therefore consider packing a battery portable charger for recharging on the go. After arriving in The United Kingdom you might need to rely on a cellphone for making a call, sending texts, using mapping to find your hotel or reading an itinerary; please make sure that your phone will have enough charge stored. [10] [AD]

SIM cards in the UK

What is the best SIM pay as you go card in Britain?

If you are travelling and need to use your cell phone abroad then you should consider using a free local SIM in the UK to avoid paying high roaming costs from your own country.

Data charges incurred with uncapped international roaming can inadvertently add hundreds to a cell phone bill unless data roaming is switched off, Wi-Fi is used or data is capped. Wi-Fi hotspots in the UK cost an average of £5 per session, therefore ordering a SIM card pre-loaded with £5 credit provides better value which can last for the duration of trip to the UK providing that data use is light.

There are 15 local mobile network providers in the UK which offer free SIM only deals online, this list of mobile providers in the UK highlights their best value deals and links directly to their SIM card ordering page:

  • O2 will send free pay and go SIM cards with prepaid £10 top ups.
  • LycaMobile can either send a free SIM without credit or the option to pay for a preloaded SIM which includes additional free credit. LycaMobile also offers £15 of free credit when transferring an existing number.
  • Vodafone offer free SIM deals with plans from only £10 per month.
  • Asda Mobile will send you a standard, micro and nano SIM card for free and offer bundles from £5 per month.
  • BT Mobile have contracts from £5 per month for their 4G data including access to their national BT WiFi, choose between a free full sized, micro or nano SIM.
  • giffgaff start with preloaded SIM cards from just £5 along with PAYG plans and also offer free calls and text between other giffgaff customers.
  • Three Mobile free SIM cards are suitable for using 4G without committing to a monthly contract.
  • Virgin Mobile Pay As You Go SIM cards offer two simple pay as you go tariffs aimed towards either heavy calls or heavy data and text usage.
  • Talkmobile offer three different sizes of free SIM cards with the option to include top up amounts as well as longer 30 day and 12 month SIM only plans.
  • Tesco Mobile send up to 4 SIM cards per UK address and offer to triple credit when ordering.
  • Lebara Mobile will supply a free SIM card, order online and credit with a minimum of £5 top up.
  • Pebble Mobile free SIM cards are the only consumer network with national roaming and inclusive EU roaming plans.
  • FreedomPop is a UK mobile provider offering one of the best SIM only deals for mobile phone users in the UK with 4G data, text and talk time. Their basic service includes a SIM card with free 200mb of data with 200 minutes and text messages every month; users can then opt to pay for additional data or switch to a paid plan as their demands grow. FreedomPop also offers a premium free SIM only card offering a one month of free trial of 1GB of data, 1000 minutes and text messages before paying an £8.95 monthly top-up with no contract or cancellation fees.

Be aware that some providers may only ship free SIM cards to UK residential or business addresses, so if you are staying in a hotel in the UK we suggest that your free SIM is delivered to a work, family or friends postal address.

You can also purchase prepaid Pay As You Go SIM cards at most UK newsagents and supermarkets, however you won´t be able to take advantage of the heavily discounted online offers. Most towns and cities in the UK have high street mobile phone stores which sell SIM cards promoting their own network at a much higher cost and will also encourage shoppers to take out a long term monthly contract.

Be aware if you are flying to a UK airport some arrival halls will sell preloaded SIM cards at highly inflated prices. Instead we recommend taking advantage of any available free airport WiFi until a suitable SIM card can be obtained once outside the airport.

SIM only contracts in the UK

For longer trips to the UK there are 4 providers which won´t ship free PAYG cards but still offer monthly SIM plans online:

  • iD Mobile have capped SIM only contracts from just £4 per month and offer data rollover with all GoTo contracts.
  • TalkTalk have SIM plans starting from less than £4 per month.
  • Truphone will send prepaid SIM cards with auto top-up and the ability to add local US and Australian numbers alongside a local UK number.
  • EE are a newly formed mobile network in the UK formally comprised of T-Mobile and Orange.

Using a free SIM card with a locked phone

If you are changing network carriers you will need to ensure you´re using an unlocked phone prior to inserting a different SIM card. If it wasn´t unlocked at the time of purchase you should be able to request to your existing cell phone provider to unlock it for a small charge, use a high street mobile phone unlocking service or look for instructions online on how to unlock your specific model of phone yourself. Be aware that the cost of unlocking a phone is likely to be substantially cheaper than paying excessive roaming charges.
