Slovakia power adapters - what plugs are used in Slovakia?

Slovak power outlet

What adapter do I need for Slovakia?

Bring a Type E plug adapter [9] to Slovakia if your plug won't fit into a Slovak power outlet.

The type of plug adapter, power converter or charger that you'll need to use when visiting Slovakia all depends on the voltage and type of device that you're attempting to power in a Slovak power outlet. If you're unclear about what voltage your device uses then please read the section on how to find out the voltage of your device first.

  • Some areas in Slovakia suffer from power cuts therefore you should pack a power bank [10] if you wish to keep your cellphone and other devices fully charged whilst abroad during a blackout.
  • If you are from America travelling to Slovakia you will need to use a plug adapter to fit a US plug into a Slovak power outlet. As the voltage is different in Slovakia bring a power converter if your device or appliance isn't dual voltage and ensure that it is compatible with a 50hz power outlet.
  • If your device is 230 volts or is dual voltage and your plug will fit in a Slovak power outlet then it will work in Slovakia.
  • If your device is 230 volts or is dual voltage but your plug won't fit in a Slovak power outlet you'll need to bring a suitable plug adapter for Slovakia such a Type E plug adapter [9]. Please Note that a plug adapter for Slovakia (or power adapter) is designed to change the actual shape of the plug on your device to fit into a plug outlet found in Slovakia, but but is unable to convert the voltage from 230 volts to another voltage.
  • If your device is unable to run on 230 volts and isn't dual voltage you'll also need a power converter for Slovakia to convert the voltage from 230 volts to the correct voltage on your device. You'll still need to use a suitable plug adapter for Slovakia if your power converter doesn't include the correct Type E plug adapter.
  • If you want to power one or more USB devices such as cellphones or tablets then a USB travel power adapter is suitable and it should be dual voltage, however make sure that you choose to bring a USB travel adapter which includes a Type E plug adapter otherwise you'll also need to use a suitable plug adapter for Slovakia.

Warning: If your device won't handle 230 volts you run the potential risk of a blown fuse, damage to your device or even an electrical fire hazard. Prior to using your device in Slovakia please read the instruction manual first to ensure safe operation.

Travel Power Strips

Travel power strips including adapters

Travel Power Strips

Benefits of a travel power strip

  • A travel power strip is able to power more than one electronic appliance or device at once using just one power outlet, costing on average $30 USD.
  • You will find some travel power strips will convert voltage for low wattage devices (for example laptops). So even if your appliance isn't dual voltage it should still function in Slovakia when using a travel power strip, making them a cheaper and lightweight alternative to a power converter.
  • Typical models should include a number of USB ports.
  • Offers surge protection. The voltage from power grids in certain countries might fluctuate, a sudden power surge can damage your electronics. Some models will have a surge protector, this will protect any electronics from being overpowered.
  • When you return home the power strip will still work as a USB charger and power strip.
  • US and Canadian power strips include Type A, B, D, E/F, G, H, I, L and N plug adapters so should work in Slovakia. (Note: UK power strips include type B, F, G and I plug adapters so you will need to use it with an additional plug adapter.)

Disadvantages of a travel power strip

  • The power converter on a travel power strip won't convert higher wattage appliances such as curling irons and hair straighteners.
  • Due to their size power strips might be too heavy for packing in hand luggage.
  • A travel power strip might be considered excessive if you only bring a small number of devices and appliances that need powering.
Power Plug Adapters

Power Plug Adapters

Benefits of a power plug adapter

  • Easy to operate.
  • Cheap, prices around $7 USD.
  • Compact and lightweight.
  • Using a Type E plug adapter [9] will work in Slovakia.

Disadvantages of a power plug adapter

  • Some hotel rooms may only have one wall outlet available, so you will only be capable of powering one appliance at a time.
  • Should you plan on visiting more than just Slovakia then you may need to pack multiple power adapter types for other countries.
  • A single adapter for each appliance - for every individual device you want to use you will also need to pack a separate plug adapter.
  • Adapter only modifies the actual shape of the plug to fit in a Type E Slovak power outlet and doesn't alter the voltage used in Slovakia. If your appliance doesn't work with 230 volts and isn't dual voltage you will also need to bring a separate voltage converter.
  • You'll also still need to bring a separate USB charger as well if you need to charge any USB device.
Plug Adapter Sets

A comprehensive plug adapter set

Plug Adapter Sets

Benefits of a plug adapter set

  • As prices are around $15-$20 USD a power adapter set works out more cost-effective purchasing than purchasing multiple $7 power plug adapters.

  • If you are visiting different locations a power adapter set is perfect.
  • Includes Type A, B, C, D, E/F, G, H, I, J, L, M and N adapters so should be suitable with a Slovak power outlet.

Disadvantages of a plug adapter set

  • Involves planning; you'll have to choose which adapters they'll need, or alternatively pack every power adapter type along.
  • Means lots of individual plug adapters to bring.
  • The remaining power adapters will be redundant and using up space.
  • Not every plug adapter types are typically included with the set (especially rarer adapters) - so ensure that your plug adapter set includes an adapter that is compatible in Slovakia.
  • Adapters only modify the shape of the plug but don't modify the actual voltage.
Voltage Converters

Larger voltage converters

Voltage Converters

Benefits of a voltage converter

Disadvantages of a voltage converter

  • A power converter only changes the 230 volts from a Slovak power outlet and not the actual shape of the plug to fit into a Slovak power outlet, so you'll still be required to pack a suitable power adapter for Slovakia.
  • The size and weight of voltage converters makes them way too bulky for carrying in hand baggage.
  • Useless after your visit to Slovakia.
  • Usually less expensive to buy a dual voltage travel appliance than to purchase a much more expensive power converter simply to power your existing domestic appliance abroad.
  • Expensive; on average $128 USD.
  • If you plan to travel to Slovakia from the US you will need one as the voltage in Slovakia is 230 volts.

Slovakia power outlets and plug sockets

What plug sockets are used in Slovakia?

Type C and E power outlets

What plug sockets are used in Slovakia?

There are two types of power supply used in Slovakia, types E and C with the primary power outlets being type E:

  • Plug Type C - This ungrounded plug outlet, technically known as a Europlug, can be recognised by two holes adjacent to each other for live and neutral.
  • Plug Type E - You can identify the wall socket by the two large holes 19mm adjacent to each other for live and neutral with a single metal earth pin protruding the top to form a triangle shape.

Do US plugs work in Slovakia?

No - an American plug won't work in Slovakia because it doesn't fit into a Slovak power outlet without the use of a power adapter. Also, the voltage is different so please use a power converter if your device isn't dual voltage and check that your appliance can work with a 50hz power outlet.

How do I use a 110 volt appliance in Slovakia?

Use a step down power converter if you wish to use a 110V appliance in Slovakia.

Are electrical plugs in Slovakia different in Europe?

Tourists in Europe

Are electrical plugs in Slovakia different in Europe?

Various locations in Europe all use different voltages and power outlet types, with eight types of power outlets used in Europe (types C, D, E, F, G, J, K and L) you might find a plug which works with a Slovak power outlet might not function correctly in an outlet in another country. If you intend on visiting more than one destination in Europe it is advised to either bring a multiple power adapter travel set [16] consisting of different types of power adapters, or a more convenient international travel plug adapter [17] as both these options ensure that you are covered for all different power outlet types which you might find. When preparing to travel check this list of power outlets used throughout Europe to understand which power converters and adapters you will require during your trip.

Is the voltage in Slovakia the same as in the US?

The voltage from a Slovak power outlet is 230 volts, but 120 volts is used in the US. If your US power charger or appliance doesn't support dual voltage then you will need to use a suitable power converter for a Slovak power outlet which allows a 120 volt American device to work in a 220-240 volt outlet.

What electrical frequency is used in a Slovak power outlet?

The frequency in a Slovak power outlet is 50Hz.

Are plug sockets in Slovakia the same as US?

An American plug won't fit in a Slovak power outlet so you will need to use a plug adapter for Slovakia. Both the voltage and frequency are different so if your charger or appliance isn't dual voltage you need to use a power converter for Slovakia and check that it works with 50hz.

Are electrical outlets common in Slovakia?

Slovakia has 100% access to electrical power throughout the country.

Are there many power outages in Slovakia?

Typically Slovakia suffers power failures around once a month.

Should I pack a portable charger for Slovakia?

Because of problems with stability of electricity in Slovakia travellers should pack backup charging options if they wish to charge devices such as cellphones reliably.

  • Whilst travelling to Slovakia increased reliance on mobile phones for storing calendars, taking photos, social networks, sat nav and staying entertained could drain the power before the end of the day. As well as the inconvenience of missed photograph opportunities this could possibly leave you in an unknown location without enough power to make an emergency call or being able to use a satellite navigation app to return to your accommodation or hotel. By packing a power bank [10] for Slovakia lowers that risk as it means you can recharge your cell phone on the go, especially when visiting a location with power outages.
  • A typical 10,000mAh power bank [10] will store enough power to cover over three full days of mobile phone use and a 20,000mAh portable charger [21] should keep a typical smart phone charged for almost seven days depending on the usage and model of the phone.
  • Providing that your laptop supports USB-C charging then bringing a portable charger for a laptop [22] marked with PD (power delivery) that supplies 20Wh or more can be used to recharge the laptop in Slovakia.
  • Before travelling please note that some airlines don't let you bring portable chargers on an aircraft that supply 100Wh of power or more and must not be kept in the hold.
  • Typical consumer portable chargers won't work with high wattage items, but a rechargeable hair dryer [19] or gas hair straighteners [20] are designed for travelling to countries with power cuts like Slovakia.
Should I pack a portable charger for Slovakia?
Do solar battery chargers work in Slovakia?

Solar bags will recharge most USB devices

Do solar battery chargers work in Slovakia?

The climate in Slovakia could be suitable for a solar power bank [24], however is likely to take time to recharge. The reduced surface area of the cells means a solar power bank will need to be left in powerful daylight for an extended period of time in order to provide enough energy for a single charge cycle, and this might prove inconvenient to continually pack and unpack a solar power bank then wait for it to recharge between cloud cover.

  • The bigger cells found on a solar backpack [23] will give the bag the ability to create more electricity within a faster period of time, and might still generate a smaller charge during overcast weather.
  • A phone which has been plugged directly into the USB port of a solar backpack will gradually top up the battery during sunny spells in Slovakia, but this might prove inconvenient to have the phone continually connected in the bag should it be used frequently. Unlike a small solar power bank which requires unpacking facing the sunlight, a solar bag is continually exposed to daylight therefore can be topping up a power bank [10] throughout the day.
  • A bag that is suitable for Slovakia should have a solar cell efficiency of 22% or greater, be able to generate at least 6 watts of power and includes a compatible power bank of 10,000mAH or stronger.
  • Solar bags are found in rucksack, laptop messenger and backpack styles making them perfect for work, domestic and travel use.
  • The durable and flexible solar cells used in solar powered bags are made to survive bending and scratching, unlike normal rigid solar panels.

Slovakia 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 Slovakia?

If travelling with more than just one device then the best travel charger for Slovakia to buy is a multiple USB charger which includes compatible plugs like a 4 port USB travel charger [2]. Slovaks use two different types of power outlets (types E and C) and bringing this ensures that you are covered for type C.

Because these chargers come with interchangeable pins and can handle 100 volts to 240 volts will mean you can travel to multiple countries around the world simply by changing the heads. If your model of device is compatible with Fast Charge then you will benefit from much quicker recharging times with one of these types of USB power adapters and additional support for more power demanding devices like tablets. Unlike other adapters having a four port adapter will allow you to charge multiple devices at the same time without needing to pack multiple power adapters or occupying additional power sockets. Because you are only packing a single international travel charger will also keep the weight and size down, making it ideal to fold up and store in hand baggage. Because of their versatility these types of travel adapters can be used at home not just abroad so when you're not on holiday they can sit overnight charging multiple tablets, phones and e-readers with just a single power outlet.

We recommend buying a versatile power adapter similar to this at your preferred electronics retailer. The multipurpose travel charger illustrated below is the 4 Port USB Wall Charger [2] which has been successfully tested with multiple USB devices in numerous foreign countries.

What USB charger do I need for Slovakia?

Why use a travel USB charger for Slovakia?

  • Most travel USB chargers include 4 or more USB charger ports, meaning you now only need to bring a single charger to charge multiple devices. Instead of bringing 4 individual power chargers you only need to pack a single 4 port USB wall charger to power up to 4 devices, thereby cutting down on the weight and size of your baggage.
  • Most travel USB power chargers should include interchangeable plug heads for various regions making them ideal when visiting different countries across Europe which will probably use different outlets to Slovakia.
  • A good power charger is lightweight, compact and rugged - perfect for rigors of travel instead of than risking bringing a domestic charger which could be hard to repair or replace in Slovakia.
  • USB chargers will accept both the 230 volt power outlets in Slovakia along with different voltage standards in other countries.
  • It is possible that hotel bedrooms or accommodation in Slovakia only have a single power outlet, by using a travel charger with multiple USB ports means you can share the single power supply with all your devices rather than waiting to charge one device at a time.
  • Because of their versatile nature they take the uncertainty out of visiting an unknown country as they are guaranteed to work practically anywhere around the world.
  • Power outlets found in airports are often sparse and demand for charging multiple cell phones and tablets from other passengers before a flight can be high, therefore a USB charger with multiple ports and the capability to fast charge is ideal.
  • Sometimes the power grid in a country can be unstable, a quality travel charger allows for unexpected spikes and prevents damage to any devices attached to it. Trying to repair an overloaded mobile phone or tablet in Slovakia might prove to be problematic and costly.
  • Larger USB chargers will also feature a power outlet strip to use multiple low powered domestic appliances such as laptops, however these are unsuitable for high powered appliances such as hair dryers or clothes irons. Read our guide on using travel appliances in Slovakia for useful advice on the best power adapter for a Slovak power outlet for high wattage devices.
  • Certain cellphones and tablets could pull more than the usual 500 milliamps supplied by a standard 5 volt USB adapter to charge or provide fast charge. More expensive USB travel chargers will support fast charging should some of your devices need additional power.
  • On back at home travel USB power chargers can also be used by recharging multiple mobile phones and tablets on an overnight basis using one power outlet.

What is the best USB charger for Slovakia?

The is the most compact option for travellers from around the world who only have USB devices, but for visitors also wishing to use their domestic plugs these power adapters provide larger but more versatile solutions. All three power converters offer surge protection which can be crucial when visiting regions with unreliable or unstable power grids. These power converters are supplied with interchangeable type C, I and G plugs covering Continental Europe, America, Australia, United Kingdom, Japan, China and over 150 destinations:

  • BESTEK Portable International Travel Voltage Converter - The BESTEK travel converter has 4 USB charging ports with 3 AC power outlets and is the best selling compact power converter for travellers originating from North America visiting Slovakia using type B American plug sockets.
  • ORICO Traveling Outlet Surge Protector Power Strip - Also having 4 USB ports but only 2 AC power outlets the travel adapter from Orico is also aimed at travellers originating from the US using type B plugs. This is a much cheaper alternative to the BESTEK with just one less AC outlet at almost half the price.
  • BESTEK International USB Travel Power Strip - This power strip has just 2 AC outlets but offers a more flexible 5 USB charging ports. This versatile power strip is compatible with both American plugs and popular plug types A, D,E/F, G, H, I, L and N making it ideal for a majority of travellers from around the world visiting Slovakia.

Power converters for Slovakia

What is a power converter for Slovakia?

Power converters allow travellers to use a 100, 110 or 120 volt electrical device with a 230 volt Slovak 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 power adapter for Slovakia?

A heavy and bulky power converter [25] will convert a 230 volt Slovak power outlet to work with a non-230 volt appliance, but a more lightweight and cheaper power adapter (or plug adapter) will change the shape of the plug on your appliance to fit into a power outlet found in Slovakia.

Do I need a power converter for Slovakia?

If you are visiting Slovakia from another country check that the device can be used with a 230 volt power supply.

  • You need a step down power converter [15] if you are travelling from a country that uses 100-120 volts and your device or appliance is incompatible with 230 volts. Read the list of world power outlets guide to see which voltage your country uses.
  • You shouldn't need a power converter if you already own either a 230 volt single voltage device or one that is dual voltage.
  • Typically, devices designed for a lower voltage (for example 110 volts) and then used with 230 volts run the risk of an electrical fire hazard, blowing a fuse or damage to your device.
  • You shouldn't need a converter if you are attempting to charge a smaller electrical device such as a tablet or mobile phone as these are typically support dual voltage and designed for international use, but you should always always check the device for dual voltage support prior to your journey.
  • For powering appliances which draw more power or generate heat (such as hair straighteners and clothes irons) then you will need to use a bulkier higher wattage heavy duty power converter [6].
  • It could be more cost effective to use a smaller robust dual voltage travel appliance than carrying a heavier high wattage power converter just to use your existing domestic appliance.
  • Read these comprehensive guides on how to use curling irons, clothes irons, hair dryers and hair straighteners in Slovak power outlets , along with guides for affordable dual voltage alternatives.

Will I need a power converter if I'm travelling to Slovakia from America?

The 230 volts from a plug outlet in Slovakia is different to a US outlet, therefore bring a step down power converter if your charger or appliance doesn't support dual voltage.

What kind of converter do I need for Slovakia?

You need to use a step down power converter [15] to use any 100-120 volt appliance in Slovakia.

What voltage does Slovakia use?

Slovakia uses 230 volts in their standard power outlets.

How to convert 230 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 230 volt Slovak 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 Slovakia before plugging that into a Slovak 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 Slovak power outlet.
What is the difference between a power transformer and a converter?

Voltage converter

What is the difference between a power 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 I tell if I have a dual voltage device?

Dual voltage hair straighteners

How can I tell if I have a dual voltage device?

The easiest way to see if your device is single voltage or dual voltage is to look for either a sticker or numbers printed on the power adapter, or on the device itself, typically on the rear or near to where the power cord sits. The location might vary depending on the make and model of your unit and should also state on the box or in the instruction manual.

  • Single voltage devices might have a specific number - such as 110V.
  • Single voltage devices could 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 say a larger voltage range separated with a slash - such as 100/240V.

A USB powered phone

What different types of devices do you need to charge in Slovakia?

  • There are three types of electrical devices:
    • Low wattage electronic devices which plug into a power outlet - for example laptops and cameras.
    • High wattage appliances which plug into a power outlet - for example hair dryers and curling irons.
    • USB powered devices which charge with a USB port - for example mobile phones and iPads.
  • When you only want to take just USB powered devices to Slovakia then a simple travel USB charger is perfect as you'll only have to bring one charger and your existing charging cables and leave your domestic chargers at home.
  • Travel power strips are designed for powering and converting voltage for many low wattage devices (such as cameras), but unsuitable for high wattage appliances that need voltage conversion.

How many devices will you be taking to Slovakia?

  • Add up how many items you intended on bringing with you to Slovakia (such as tablets, mobile phones, eReaders, hair dryers or curling irons).
    • Remember to take into account that you might own more devices at a later date. Do you intend on buying a new mobile phone computer soon?
    • There is a growing number of smaller rechargeable devices such as electric shavers which use USB charging for their power charging source. The next time you have to replace a device it could need a USB adapter so please check that your travel adapter has enough spare ports to power these also.
  • Are you bringing children along who might need to recharge their devices as well?

How many Slovak power outlets are available?

Are multiple outlets available

How many Slovak power outlets are available?

  • Hotels in Slovakia might only offer one power outlet. This will be an inconvenience when charging up the batteries of more than one device overnight because you will only be able to charge one device at a time.
  • To recharge multiple devices at the same time we suggest using a travel USB wall charger or a travel power strip which can power multiple USB ports or power outlets.

What is your budget?

  • A basic power adapter starts from around $7 which powers one device from a Slovak power outlet (providing that works with 230 volts or is dual voltage), but investing in around $20 means you can charge multiple devices at once and be able to use them in multiple different countries.

Are you planning to visit anywhere else abroad in the future?

Do you intend on visiting countries other than Slovakia?

Are you flying long haul to travel to Slovakia?

Are you flying long haul to travel to Slovakia?

  • If you are embarking on an extended trip to get to Slovakia it's worth considering an airport-suitable charger that works in different power outlet types, one that can be packed in hand luggage and can be used to power phones and tablets.
  • As not all flights actually have power outlets for customers please consider bringing a portable charger [10] which will recharge on the go. After landing in Slovakia you might have to use a mobile phone for making a telephone call, messenging, using mapping to locate accomodation or recalling itineraries; therefore it is recommended that your phone will have ample battery power remaining.
