What adapter do I need for Oman?

You need to pack a Type G plug adapter [3] for Oman if your plug won't fit into an Omani power outlet.

The type of power adapter, power converter or charger that you'll need when visiting Oman all depend on the voltage and type of device that you're attempting to charge with an Omani power outlet. If you do not know which voltage your device uses then read the section on how can you tell if you have a single voltage or dual voltage device first.

  • If you are from the US visiting Oman then you will need to use a suitable plug adapter for Oman to fit a US plug into an Omani power outlet. Because the voltage is different in Oman pack a power converter if your device or appliance isn't dual voltage and ensure that it will work with a 50hz power outlet.
  • If your device is 240 volts or is dual voltage and your plug fits in an Omani power outlet then you can use it in Oman without needing a plug adapter.
  • If your device is 240 volts or is dual voltage but the plug won't fit in an Omani power outlet then you'll need a suitable plug adapter for Oman such a Type G plug adapter [3]. A plug adapter for Oman (or power adapter) will only change the actual shape of the plug on your device to fit into a plug outlet found in Oman, but won't convert the voltage from 240 volts to another voltage.
  • If your device doesn't run on 240 volts and isn't dual voltage then you'll also need a power converter for Oman to convert the voltage from 240 volts to the correct voltage on your device. You will still need to pack a suitable plug adapter for Oman if the power converter doesn't use the correct Type G plug adapter.
  • If you need to power USB devices such as cell phones or tablets then a USB travel power adapter is suitable and it should be dual voltage, but make sure that you choose one which includes a Type G plug adapter otherwise you will also need to use a suitable plug adapter for Oman.
  • Excess use of a cellphone during a vacation to Oman can leave you with a flat battery quickly therefore you should pack a portable charger [4] if you wish to recharge your mobile phone whilst travelling to an unknown location.

Warning: If your device won't handle the 240 volts used in Oman you run the potential risk of damage to your device, an electrical fire hazard or blowing a fuse. Prior to using your device in Oman please check the instruction manual first to ensure safe operation.

Type C and G power outlets

What plug sockets are used in Oman?

There are two types of power outlets used in Oman, types G and C with the primary power outlets being type G:

  • Plug Type C - The plug socket, technically called a type C socket or Europlug, is recognised by the two circular adjacent holes for live and neutral pins.
  • Plug Type G - This wall outlet, also called a type G power outlet, looks like three vertical rectangular slots in a triangle pattern for live, neutral and earth pins.

Do US plugs work in Oman?

No; a US plug won't work in Oman because it can't fit into an Omani power outlet without using a power adapter. The voltage is 240 volts so please use a power converter for Oman if your device isn't dual voltage and check that your device can work with a 50hz power outlet.

How do I use a 110 volt appliance in Oman?

To use a 110V appliance in an Omani power outlet you need a step down power converter.

Is the voltage in Oman the same as the US?

The voltage in Oman is 240 volts, but 120 volts is used in America. If your American charger or appliance isn't dual voltage then you will need to use a power converter for Oman which can change the voltage from 240 volts to 120 volts.

Is an Omani power outlet the same as the US?

US plugs won't fit in an Omani power outlet therefore you will need to bring a plug adapter for Oman. Both the voltage and frequency are different so if your appliance or charger isn't dual voltage you need to use a power converter for Oman and ensure that it works with 50hz.

What electrical frequency is used in Oman?

The frequency of the current from an Omani power outlet is 50Hz.

How reliable is the electricity in Oman?

Even though consistent power can't be guaranteed, the power grid in Oman is reliable as there is no pattern of regular power failures compared to other countries.

Are power outlets available in Oman?

100% of population has access to electricity in Oman.

Should I bring a portable charger to Oman?

USB power bank for charging smartphones

Should I bring a portable charger to Oman?

Whilst power blackouts aren't regular with electricity being available throughout the country, travellers should still bring a power bank to recharge mobiles and other devices.

  • With many being offline can cause mild stress, especially when being relied upon in an unknown location. During a trip to Oman increased reliance on smart phones for storing itineraries, taking photographs, sat nav, social networks and playing games could syphon off power excessively. A flat mobile phone battery could possibly leave you stranded without sufficient power to make an emergency call or being able to use GPS to return back to your accommodation. By packing a portable charger [4] for Oman lowers the risk as it allows you to power up your cell phone without needing an Omani power outlet.
  • A typical 10,000mAh portable charger [4] can store enough energy to cover around three full days of mobile phone use whilst a 20,000mAh portable charger [14] should keep a typical mobile phone powered for almost a week depending on the model of phone and usage.
  • If your laptop uses a USB-C charging port then bringing a portable charger for a laptop [15] marked with PD (power delivery) that supplies at least 20Wh can be used to recharge your laptop.
  • Be aware that some airlines prohibit portable chargers on an aircraft that supply 100 Wh of power or more and must be kept in carry-on luggage only.
  • Consumer portable chargers won't work with high powered items that generate heat, but a rechargeable hair dryer [12] or gas hair straighteners [13] are ideal for travelling.
Do solar chargers work in Oman?

Solar backpacks are ideal in hot weather

Do solar chargers work in Oman?

The sunlight in Oman will be suitable enough to recharge solar power bank [17] reliability, but needs to be left in strong sunshine to provide suitable energy for a single charge cycle. It could prove inconvenient to continually unpack a solar power bank and wait for it to recharge in a sunny area.

  • Instead, the bigger durable solar cells found on a solar backpack [16] give the bag the ability to generate more power within a shorter period of time and could still generate some power when overcast, making them ideal for the climate in Oman.
  • A device that has been directly plugged into the USB port of a backpack should trickle charge the power during sunny spells in Oman, however this could be inconvenient to have it continuously connected in the bag during the day should it be needed constantly. Therefore it is recommended to plug a power bank [4] to a solar backpack which can then be constantly recharged during the day, afterwards the phone can be powered up using the power bank without sunshine.
  • Although the sunlight in Oman is strong, a bag should have a solar cell efficiency of 22% or more, can generate a minimum of 6 watts of energy and can be used with a 10,000mAH power bank or stronger. Unlike regular rigid solar cells, the flexible and durable solar cells used in solar powered bags have been made to endure bending and scratches. Solar bags are available in rucksack, backpack and laptop messenger styles which makes them perfect for work, domestic and travel.

Oman 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 Oman?

If travelling to multiple countries the best travel power adapter for Oman to buy is a multiple USB port adapter which includes swappable plugs like a 4 port USB travel charger [7]. There are two types of wall outlets in Oman (types G and C) and using a travel charger like this ensures that you are covered for both types C and G. Because these types of chargers come with interchangeable plugs and can handle from 100 - 240 volts it makes them ideal for multiple countries in Europe, Asia, North America and Africa just by changing the included plugs. If your device is compatible with Fast Charge (note that not all USB devices do) then you will benefit from much quicker charging times with one of these travel adapters, along with additional support for certain power demanding devices. Having a 4 port charger means you can charge more than one device at the same time without needing to bring individual power chargers for your Omani trip or occupying additional power outlets. Only bringing a single travel charger will keep the overall size and weight down, making it ideal to store in hand baggage. Due to their flexibility these types of travel chargers can be used at home as well as abroad so when you're not travelling they can be used overnight charging multiple tablets and phones with only a single wall outlet.

If you travel frequently we recommend buying this type of flexible power charger at your preferred electronics retailer. The power adapter illustrated below is the 4 Port USB Wall Charger [7] which has been tested successfully for recharging multiple USB devices in numerous countries.

What USB charger do I need for Oman?

Why use a travel USB charger for Oman?

  • Normal travel USB chargers include 4 or more USB charger ports, this means that you now only need to bring one charger to charge multiple devices. Rather than bring 4 individual power chargers it becomes only necessary to pack one 4 port USB wall charger to power up to 4 individual devices which cuts down on the weight and size of your luggage.
  • All travel USB power chargers should include interchangeable plug heads for different power outlet types. This is ideal if travelling across different countries which will probably use a different standard to Oman.
  • Good USB travel chargers are compact, rugged and lightweight - ideal for the rigors of travel instead of than risking packing a domestic charger which could be hard to repair in Oman.
  • USB chargers will accept the 240 volt power outlets in Oman along with other voltage standards in other countries.
  • There is a possibility that accommodation or hotel rooms in Oman might only have a single wall outlet, by using a travel charger with multiple USB ports allows you to share the single wall outlet with all your devices instead of having to wait to recharge each device one by one.
  • Because of their flexible nature they take the worry out of visiting any unknown country as they are guaranteed to work almost anywhere around the world.
  • Power outlets found in airports can be scarce and demand for charging multiple devices before a flight can be high, therefore a USB travel charger with multiple ports and the capability to fast charge is perect.
  • The power grid in some countries can be unstable, a travel charger allows for unexpected fluctuations to prevent damage to any devices attached to it. Attempting to repair an overloaded cell phone or tablet in Oman might prove problematic and expensive.
  • More expensive USB travel chargers will also include a power outlet strip to allow you to use low powered devices such as laptops, however these will be unsuitable for high powered domestic such as hair dryers or clothes irons. Please refer to our section on using travel appliances with an Omani power outlet for helpful guidelines and advice on the most suitable power adapter for an Omani power outlet for high wattage appliances.
  • Some mobile phones could pull more than the standard 500 mA produced from a normal 5 volt USB adapter to charge or provide fast charge. Ensure that the USB power adapter can support fast charging should any of your devices need extra power.
  • Travel USB chargers can also be useful back at home by charging multiple mobile phones every night using only a single power outlet.

Power converters for Oman

What is a power converter?

Power converters for Oman allow travellers to use their 100-120 volt electric appliance with a 240 volt Omani 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 Oman?

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 found in Oman, but a more expensive and heavier power converter [18] transforms a 240 volt Omani power outlet to work with a non-240 volt device.

Do I need a power converter for Oman?

When visiting Oman from another country please ensure the device will accept 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 device won't support 240 volts. Read our world power outlets guide to discover which voltage your country uses.
  • You don't need a power converter if you are already using either a single voltage appliance that works with 240 volts or one that is dual voltage.
  • Devices designed to use a lower voltage such as 110 volts and then used in a 240 volt outlet run a risk of an electrical fire hazard, blowing a fuse or damage to your device unless you use a step down power converter [10].
  • You shouldn't need a power converter if you wish to power a smaller electrical device such as a cell phone as these are typically designed for international use and support dual voltage, but you should always check the device for dual voltage support prior to your journey.
  • If powering high wattage appliances or generate heat (such as curling irons or hair straighteners) then you will need to use a bulkier higher wattage heavy duty power converter [19] to allow the appliance to be used with a 240 volt Omani power outlet.
  • Purchasing a smaller lightweight dual voltage travel appliance could be more practical and cost effective than trying to bring a heavier power converter just to use your existing domestic appliance.
  • For more information read these comprehensive travel guides on using curling wands, clothes irons, hair straighteners and blow dryers with an Omani power outlet , along with advice on affordable dual voltage alternatives.

Do I need a power converter for Oman if I'm travelling from the US?

The 240 volts used in a wall outlet in Oman is different to an American supply, therefore please bring a step down power converter [10] if your charger or appliance isn't dual voltage.

What kind of converter do I need for Oman?

In order to use any 100-120 volt appliance in a 240 volt Omani power outlet you need a step down power converter [10].

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 an 240 volt Omani 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 Oman before plugging that into an Omani 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 an 240 volt Omani power outlet.

What voltage is used in Oman?

Oman uses 240 volts in their normal power outlets.

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

Voltage converter

What is the difference between a power 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.
Is my device single voltage or dual voltage?

Single voltage hair straighteners

Is my device single voltage or dual voltage?

The easiest method to see if a device is either single voltage or dual voltage is to look for numbers printed on the power plug, or on the appliance itself, normally near to where the power cord plugs into. The location will vary depending on the make and model of your device, it should also be written in the instruction manual.

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

Key to electrical adapter comparison

  1. Compatible number of countries based on data from the International Electrotechnical Commission World Plugs page (cited November 2018).
  2. Assuming only a single plug adapter from the plug adapter set will be used at any one time in a compatible location.
  3. Depending on if the power strip supports voltage conversion for low wattage items. All travel power strips tested do not convert voltage for high wattage appliances.
  4. Including the device itself, any supplied plug heads and power cords.
  5. Some travel power strips featuring less AC outlets may be small and lightweight enough to be suitable for hand luggage.
  6. Number of items if bringing an entire set of plug adapters for use in multiple locations to cover all eventualities (unless bringing only the necessary single plug adapter).

What type of adapter do you need for Oman?

Deciding which type of electrical adapter you need for Oman

The power converter that is best to bring to Oman depends on your requirements, so before choosing the right adapter to use we recommend reading the following checklist:

What types of devices do you want to charge in Oman?

Make a list of items you need

What types of devices do you want to charge in Oman?

  • There are three different types of electrical devices:
    • Low wattage electrical items that plug into an electrical outlet - for example a laptop.
    • High wattage electrical appliances which can be plugged into a power outlet - for example hair dryers and clothes irons.
    • USB powered electrical devices which connect to a USB port - for example phones.
  • If you only want to bring along just USB powered devices to Oman then you'll find that a travel USB charger is ideal as you'll only have to pack one lightweight charger and leave your domestic chargers at home.
  • Travel power strips are made for providing power and converting voltage for several low wattage devices (such as cameras), but won't work with high wattage appliances that require voltage conversion, potentially damaging the travel power strip.
How many electrical items are you packing for Oman?

How many devices are you taking

How many electrical items are you packing for Oman?

  • List how many electronic you want to bring to Oman (including laptops, phones, tablets, eReaders, clothes irons and hair dryers).
    • Take into account that you might own more electrical items at a later date. Are you thinking about purchasing a new cell phone computer soon?
    • There are a growing amount of smaller rechargeable electronics such as electric shavers which utilise USB charging as a power charging source, the if you have to buy a new device it might use a USB adapter so check that your travel adapter has enough spare ports for these additional devices also.
  • Are you also bringing family along that will need to recharge their iPads too?

Will your devices work with a 240 volt power outlet?

Will you only be charging USB devices in Oman?

  • Should you only plan on packing devices such as phones and tablet computers to use in Oman then we suggest just bringing a travel USB wall charger.
  • If you only use a simple power plug adapter you'll still need to use your domestic USB power charger as well.
How many wall outlets are available in Oman?

How many power outlets will be available

How many wall outlets are available in Oman?

  • Accommodation in Oman may have only a single power outlet on the wall. This could present a problem when charging batteries of multiple items such as tablets, cellphones or laptops overnight because you can only charge one device at a time then need to continually swap after each device has charged.
  • If you want to charge multiple devices at the same time then we suggest bringing a USB wall charger or a travel power strip that are capable of powering multiple USB ports and outlets.

How much can you afford?

  • A basic power adapter starts at $7 which will power only one device in one country (providing that works with 240 volts or is dual voltage) but paying roughly $20 means you can power more than one device at once and you will be able to use them in multiple countries.

Is Oman the only country you plan to visit?

Do you intend to visit anywhere abroad in the future?

How long does it take to get to Oman?

Arriving at an airport

How long does it take to get to Oman?

  • For extended journeys it's worth thinking about bringing a convenient charger which is perfect for airports that works in different power outlet types, one which is light enough to pack in hand luggage and can charge phones and tablets right before an extensive trip.
  • As not all airports have power outlets please think about packing a battery portable charger [4] for recharging on the go. When you land you might need to rely on a cell phone to make calls, messenging, using sat nav to locate a hotel or viewing itineraries; so ensure that your phone will have enough power stored.
Do you bringing just hand luggage?

Are you bringing just hand baggage

Do you bringing just hand luggage?

Would you like to use your charger when returning to America?

Are you visiting other countries with reliable access to electrical power?

  • Power in Oman is stable however if you plan to visit other countries you may need an electrical adapter which will protect your electrical devices. Voltage could sporadically fluctuate in some regions and this might cause damage to your devices, use a power adapter which has surge protection built in such as a travel power strip.
  • Using a portable charger [4] or a solar backpack [16] will prepare you for countries with limited electricity access or any power cuts.
