What adapter do I need for Peru?

You'll need to bring a Type C plug adapter to Peru if your plug doesn't fit in a Peruvian power outlet.

The type of power adapter, power converter or charger that you'll need when visiting Peru all depends on the voltage and type of device that you're trying to power in a Peruvian power outlet. If you're unsure of what voltage your device can use then please read the section on how can you tell if you have a single voltage or dual voltage device before going any further.

  • Certain areas in Peru do not have access to electricity and suffer from power blackouts, it is advised to pack a portable charger if you want to recharge your mobile phone whilst staying in a region without electricity or during a blackout.
  • If you're travelling to Peru from the US then we recommend bringing a power adapter for Peru as US Type A or Type B outlets might not commonly be used. Because the voltage is different in Peru use a power converter for Peru if your device isn't dual voltage.
  • If your device can run on 220 volts or is dual voltage and your plug can fit in a Peruvian power outlet then it can work in Peru.
  • If your device can run on 220 volts or is dual voltage but your plug won't fit in a Peruvian power outlet then you will need to bring a suitable plug adapter for Peru such a Type C plug adapter. A plug adapter for Peru (or power adapter) only changes the shape of the plug on your device to fit into a plug outlet found in Peru, but but is unable to change the voltage from 220 volts to a different voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage you will also need a power converter for Peru to convert the voltage from 220 volts to the correct voltage on your device. You will still need to pack a suitable plug adapter for Peru if the power converter doesn't use the correct Type C plug adapter.
  • If you simply want to recharge your USB devices such as mobile phones or tablets then a USB travel power adapter is recommended and it should be dual voltage, however ensure that you bring a USB travel adapter which has a Type C plug adapter otherwise you will also need to pack a suitable plug adapter for Peru[3] [AD]

Warning: If your device won't handle 220 volts you run a risk of a blown fuse, damage to your device or even an electrical fire hazard. Prior to using your device in Peru check the instruction manual first to ensure safe operation.

  • The interchangeable heads don't include one which is compatible with a Peruvian power outlet - therefore you'll still need to bring a separate power adapter for a Peruvian power outlet.
  • They only have USB ports so you will be unable to power any electrical appliances, only USB ones. [7] [AD]
Travel Power Strips

Travel power strip including plug adapters

Travel Power Strips

Benefits of a travel power strip

  • Certain models are able to convert voltage for low wattage electronics (for example laptops). So therefore if the electronic device isn't dual voltage it should still be used in Peru by using just a travel power strip. This will make a travel power strip a cheaper and lightweight substitute for a power converter.
  • Able to charge many electrical appliances and devices concurrently using only a single Peruvian power outlet, costs under £40.
  • Most models will also feature a number of USB charge ports.
  • The voltage from power outlets in certain areas could fluctuate, a surge in power might damage your delicate electrical items. There are some travel power strips that include a surge protector to protect any device from being overloaded by an unstable power grid.
  • It will still be of use back at home.

Disadvantages of a travel power strip

  • Not supplied with the correct plug adapter for Peru therefore you should pack an additional power plug adapter for a Peruvian power outlet as well .
  • Unlike a dedicated voltage converter, the voltage converter on a travel power strip won't work with high wattage appliances such as hair straighteners or clothes irons.
  • Due to their size power strips might be unsuitable for packing in hand luggage.
  • Travel power strips might be excessive if you only bring a small number of items to power. [8] [AD]

Voltage Converters

Those originating from The United Kingdom will not need a converter as the voltage in Peru is 220 volts.

Benefits of a voltage converter

Disadvantages of a voltage converter

  • It only changes the 220 volts from a Peruvian power outlet and not the shape of the plug to fit into a Peruvian power outlet, therefore you will still need to pack the right type of plug adapter for Peru.
  • The normal weight of voltage converters makes them impractical for carrying in hand luggage.
  • An expensive power converter is redundant when you return to the UK.
  • It's usually less expensive to bring a dual voltage travel appliance than to purchase an expensive power converter just to bring your existing single voltage domestic appliance abroad.

Peru power outlets and plug sockets

What plug sockets are used in Peru?

Type A, B and C power outlets

What plug sockets are used in Peru?

There are three different types of power outlets used in Peru, types C, A and B with the primary power outlets being type C socket:

  • Plug Type A - You can identify this plug socket by the 2 slots adjacent to each other where the live and neutral blades sit.
  • Plug Type B - You can recognise the plug outlet by 2 thin slots adjacent to each other where the short two blades sit with a single hole below for the longer earth pin.
  • Plug Type C - You can recognise the power outlet by two circular holes adjacent to each other for live and neutral. [3] [AD]

How do I use a 110 volt appliance in Peru?

To use a 110 volt appliance in a Peruvian power outlet you need to use a step down power converter.

What is the frequency used in a Peruvian power outlet?

The frequency from a Peruvian power outlet is 60 Hz. [11]

Is there good access to electricity in Peru?

Almost 10% of the population doesn't have access to electricity in Peru.

Are there power outages in Peru?

It is reported that there are potentially monthly power failures in Peru.

Should I pack a power bank for Peru?

Because electricity isn't available to 100% of the population of Peru together with potential power blackouts, travellers should use alternative charging options if they need to continue using devices such as mobile phones or eReaders.

  • During a trip to Peru increased reliance on smart phones for taking photographs, storing itineraries, social network sharing, getting directions and staying entertained can syphon off power more excessively than normal. As well as the simple missing photograph opportunities a flat mobile phone battery can potentially leave you without enough power to make an emergency call or being able to use a GPS app to find your way back to hotel. Using a 10,000mAh portable charger in Peru lowers that risk as it allows you to recharge your smart phone on the go, especially when travelling to a country with limited access to electricity and power cuts in some areas.
  • A 10,000mAh power bank will supply enough power to cover around 3 full days of mobile phone use whilst a 20,000mAh portable charger should keep a typical mobile phone powered for around seven days.
  • Providing that your laptop uses a USB-C charging port then packing a portable charger for a laptop marked with PD (power delivery) which supplies 20Wh or more can be used to extend the battery life of the laptop when travelling to Peru. 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 so please check ahead with the carrier first.
  • Consumer portable chargers won't work with high powered items that generate heat, although a rechargeable hair dryer or gas hair straighteners are designed for travelling to locations with both power cuts and a lack of access to electricity like Peru.    [12] [12] [13] [14] [15] [16] [AD]

Does a solar powered charger work in Peru?

Solar backpacks are ideal in hot countries

Does a solar powered charger work in Peru?

The climate in Peru will be suitable enough to recharge solar power bank dependably, but needs to be left in strong sunlight in order to provide adequate power for a single charge. It may prove inconvenient to constantly unpack a solar power bank then wait for it to recharge in sunny spells.

  • The bigger durable solar panels found on a solar backpack give the backpack the ability to create more electricity within a shorter period of time, making them ideal for the climate in Peru.
  • A phone that is plugged directly into a USB port of a solar backpack can trickle charge the battery during sunny periods in Peru, however this could be inconvenient to have it continually tethered in the bag if it is to be used frequently. A solar powered bag is usually exposed to daylight therefore can be powering up a power bank during the day, unlike a handheld solar power bank that requires unpacking and facing sunlight.
  • Although the climate in Peru is suitable, a bag should have a solar cell efficiency of at least 22%, be able to generate at least 6 watts of power and includes a 10,000mAH power bank or greater. Unlike regular rigid solar cells, the flexible and durable solar cells used in solar powered bags are designed to survive scratching and bending. They are found in laptop messenger, rucksack and backpack styles which makes them perfect for travel, domestic and work.  [17] [18] [AD]

Peru 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 Peru?

When you are travelling to multiple countries then the best international travel charger for Peru is a multiple USB charger which includes compatible plugs such as a 4 port USB travel charger. There are three different types of plug sockets that Peruvians use (C, A and B) and using a travel charger like this will ensure that you are covered for both types A and C.

As these chargers are supplied with interchangeable pins and can handle from 100 volts - 240 volts it makes them ideal for multiple countries in North America, Europe, Asia and Africa just by switching the plugs over. If your model of device supports Fast Charge (not all USB devices do) then you will benefit from much quicker charging times with one of these types of USB travel chargers plus compatibility with more power hungry devices. Unlike other adapters having a 4 port adapter will also allow you to charge multiple devices at once without needing to buy multiple travel chargers for your Peruvian trip. Because you are only needing to pack a single lightweight travel charger will help keep the size and weight down, making it ideal to store in hand baggage while travelling and suitable for recharging your devices at an airport or on a plane. Because of their flexibility these types of chargers can be used at home as well as abroad so when you're not on holiday they can be used under your bedside table charging multiple smartphones and tablets with only a single power outlet.

We suggest searching for this type of versatile travel adapter at your preferred electronics retailer. The multipurpose travel adapter illustrated here is the 4 Port USB Wall Charger which has been successfully tested for powering multiple USB devices in numerous foreign countries around the world. [7] [AD]

What USB charger do I need for Peru?

Why use a travel USB charger for Peru?

  • Normal travel USB chargers include 4 or more USB charger ports, meaning you only need to bring one charger to charge multiple devices. This helps reduce the weight of your baggage by only bringing one USB wall charger rather than bringing several different USB chargers.
  • Travel USB power chargers will include swappable plug heads for different power outlet types. This is ideal when visiting different countries across South America which are likely to use different standards to Peru.
  • Good USB travel chargers are lightweight, compact and rugged; perfect for the rigors of travel rather than risking bringing a domestic charger which could be impossible to repair or replace in Peru.
  • USB travel chargers will accept the 220 volt power outlets in Peru along with other voltage standards in other countries.
  • There is a chance that some hotels in Peru only have one wall outlet, by using a travel charger with multiple USB ports means you can share the single wall outlet with all your devices rather than having to wait to recharge each device one by one.
  • Because of their versatile nature a travel USB charger takes the uncertainty out of travelling to an unknown destination as they are guaranteed to work almost anywhere on the planet.
  • Power outlets found in airports can be in short supply and demand for charging multiple cell phones and tablets from other passengers during departure can be high, therefore a USB charger with multiple ports and the ability to charge quickly is perfect.
  • Sometimes the power grid in a country can be unstable, a good quality travel charger allows for unexpected fluctuations and will prevent damage to any devices attached to it. Attempting to repair an overloaded mobile phone in Peru might prove to be difficult and costly.
  • Larger USB chargers also incorporate a power outlet strip to allow you to plug in low powered devices such as laptops, however these will be unsuitable for high wattage appliances such as hair dryers or clothes irons. Read our section on using travel appliances in Peru for useful guidelines and advice on the most suitable power adapter for a high powered devices with a Peruvian power outlet.
  • Certain mobile phones could pull more than the standard 500 milliamps supplied by a normal 5 volt USB adapter to charge or provide fast charge. Quality USB chargers will support fast charging incase any of your devices need extra power.
  • When returning home travel USB power chargers can also be useful by recharging multiple cell phones every day using a single power outlet. [7] [AD]

What is the best USB charger for Peru?

A 4 port USB travel charger is the most compact option for travellers from any country wanting to recharge devices using USB, but for visitors also wishing to use their domestic plugs the following power adapters provide larger but more versatile solutions. All three power strips offer surge protection which is useful when visiting counties with unreliable power grids to prevent damage to any connected devices. These power adapters come with interchangeable type C, I and G plugs covering Continental Europe, North America, Australia, United Kingdom, Japan, China and over 150 destinations:

Power converters for Peru

What is a power converter for Peru?

A power converter for Peru enables you to use a 100, 110 or 120 volt electric device with a 220 volt Peruvian 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 for Peru?

A lightweight, cheap and small power adapter (or plug adapter) changes the shape of the plug on your device to fit into a power outlet found in Peru, however an expensive and bulkier power converter will transform the voltage of 220 volts from a Peruvian power outlet to work with a non-220 volt appliance. [19] [AD]

Do I need a power converter for Peru?

If travelling to Peru from another region check your device can accept a 220 volt power supply.

  • A step down power converter is needed if you are travelling to Peru from a country that uses 100-120 volts and your device or appliance doesn't support 220 volts. Read our world power outlets guide to find out the voltage is used in your country.
  • You don't need a power converter if you already own either a 220 volt device or one that supports dual voltage.
  • Electrical devices designed to use a lower voltage (such as 110 volts) and used in a 220 volt outlet run the potential risk of damage to your device, an electrical fire hazard or blowing a fuse unless a step down power converter is used.
  • You shouldn't need a power converter if you wish to power a smaller electrical device such as a laptop as these are normally dual voltage and designed for international use, however you should always always check the device for dual voltage support prior to your journey.
  • If supplying power to appliances which draw more power or generate heat (such as hair dryers and curling irons) then you will need to use a much larger higher wattage heavy duty power converter.
  • Purchasing a smaller lightweight dual voltage travel appliance might be more cost effective and practical than investing in a heavier high wattage power converter in order to use your existing domestic appliance in Peru.
  • Read our comprehensive travel guides on how to use curling wands, clothes irons, hair dryers and hair straighteners with a Peruvian power outlet which includes guides on affordable dual voltage alternatives.  [10] [20] [AD]

What converter do I need for Peru?

If you want to use any 100, 110 or 120 volt appliance in Peru you will need a step down power converter[10] [AD]

How to convert 220 volts to 110 volts

  1. Use a step down power converter to allow you to use a 110 or 120 volt appliance with a 220 volt Peruvian 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 Peru before plugging that into a Peruvian 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 220 volt Peruvian power outlet. [10] [AD]

What voltage is used in Peru?

Peru uses 220 volts in their standard power outlets. [2]
What is the difference between a transformer and a converter?

Voltage converter

What is the difference between a transformer and a 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 can you tell if you have a single voltage or dual voltage device?

Dual voltage hair straighteners

How can you tell if you have a single voltage or dual voltage device?

The easiest method to tell if your device is dual or single voltage is to check for a sticker on the existing power plug, or on the appliance itself, normally near to where the power cord sits. This location might depend on the make or model of your unit but should also be written in the instruction manual or on the box.

  • Single voltage devices could have a specific number - such as 110V.
  • 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 normally say a large voltage range separated with a slash - such as 110/240V.

  • Should you only intend on using USB powered electronics such as mobile phones for Peru then it is recommended to just bring a travel USB wall charger.
  • If you only use a simple power plug adapter you will still need to bring the USB charger that was supplied with your device as well. [7] [AD]

  • A hotel might only offer a single power outlet on the wall. This will present an inconvenience if charging up batteries of more than one electronic device overnight because you can only charge a single device at a time every few hours.
  • To recharge more than one device at the same time look to bringing a travel USB wall charger or a travel power strip which are capable of charging multiple USB ports and outlets. [8] [AD]

What is your budget?

  • A basic power adapter starts at under £10 which charges a single device from a Peruvian power outlet (provided that works with 220 volts or it is dual voltage) but investing in roughly £20-£25 will allow you to charge multiple devices simultaneously and be able to bring them to various countries.

Is Peru the only country you plan on visiting?

  • Single power adapters only typically work in a single country which they are built for, therefore if you need to visit multiple countries you may need to bring additional power adapters which can in turn add to the number of adapters you'll have to bring.
  • On the other hand travel USB wall chargers and universal travel adapters are designed for travelling to more than one country becuase of their interchangeable head system.

Are you flying long haul to get to Peru?

  • If you're taking a longer trip to get to Peru it's worth thinking about packing an appropriate airport-friendly charger that works in different outlet types, one which is light enough to pack in carry-on luggage and can top up tablets and phones.
  • As not all flights have power outlets available for the public we recommend packing a travel portable charger which will recharge on the go. When you land you could have to rely on your phone for making a call, receiving messages, using sat nav to locate a hotel or recalling an itinerary; therefore it is recommended that your phone has enough battery power left. [4] [AD]

Will you always have reliable access to electrical power?

  • The power could sporadically fluctuate in Peru and this might cause damage to your devices, look for a power adapter which has surge protection such as a travel power strip.
  • Because Peru has power cuts and having partial access to electricity you might find that whatever power charger you pack for the country doesn't work anyway. Using a portable charger or a solar backpack will prepare you for power cuts and limited electricity access.  [4] [4] [17] [AD]
