Hong Kong power outlet

What adapter do I need for Hong Kong?

You will need to use a Type G power adapter for Hong Kong if your plug won't fit in a Hong Kong power outlet.

The type of power adapter, converter or charger that you'll need to use when visiting Hong Kong will all depend on the voltage and type of device that you're trying to charge in a Hong Kong power outlet. If you do not know which voltage your device can use then please read the section about how can you tell if you have a single voltage or dual voltage device first.

  • If you're from America travelling to Hong Kong then you will need to bring a plug adapter to fit a US plug in a Hong Kong power outlet. Because the voltage is different in Hong Kong use a power converter if your device isn't dual voltage and check that it will work with a 50hz power outlet.
  • If your device can run on 220 volts or is dual voltage and the plug fits in a Hong Kong power outlet then you can use it in Hong Kong without needing anything else.
  • If your device can run on 220 volts or is dual voltage but the plug doesn't fit in a Hong Kong power outlet then you'll need to bring a suitable plug adapter for Hong Kong such a Type G power adapter. A plug adapter for Hong Kong (or power adapter) only changes the actual shape of the plug on your device to fit into a plug outlet found in Hong Kong, but won't change the voltage from 220 volts to use with another voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage then you will also need a power converter for Hong Kong to convert the voltage from 220 volts to the correct voltage on your device. You'll still need to pack a suitable plug adapter for Hong Kong if the power converter doesn't have the correct Type G power adapter.
  • If you want to power one or more USB devices such as cellphones or tablets then a USB travel power adapter will be ideal and it should be dual voltage, however make sure that you bring one which includes a Type G power adapter otherwise you'll also need to bring a suitable plug adapter for Hong Kong[3] [AD]
  • Excess use of a mobile phone during a trip to Hong Kong could create an additional drain on the battery, we suggest packing a power bank if you want to keep your mobile phone charged throughout the day whilst visiting an unknown location.

What does a power adapter for a Hong Kong power outlet do?

A power adapter enables visitors travelling from a different country to use their electronic and electrical appliances and devices in Hong Kong by adapting the shape of the power plug from one type to another.

Where to buy a power adapter in Hong Kong

Arriving at an airport

Where to buy a power adapter in Hong Kong

On arrival power adapters could be found in local electrical high street shops and drug stores, but always check the build quality first as safety standards might be different in a foreign country as this is important when dealing with electrical goods. Keep in mind that a shopping trip searching for power adapters in an unknown location might be impractical, especially as this needs to happen quickly before batteries run out.

Hotel receptions could have a power adapter for sale, hire or as a complimentary extra for guests; however, availability is normally limited and a hotel might not have the exact type required for your country. If in doubt, call ahead to the hotel first and request a reservation as it is unlikely that an adapter will be found in your room on arrival.

  • Lacking an in-built power converter will mean it isn't suitable for electrical devices which don't support 220 volts in Hong Kong. [7] [AD]
Travel Power Strips

Power strips have AC and USB sockets

Travel Power Strips

Benefits of a travel power strip

  • Able to power more than one electronic appliance or device at once using just one power outlet.
  • Some models of travel power strips offer voltage conversation for lower wattage electronics. So therefore if the device isn't dual voltage it should still be used with a Hong Kong power outlet by using just a travel power strip. This can make them a cheap lightweight substitute for a dedicated voltage converter.
  • Most power strips also include a number of USB charge ports.
  • Voltage from power grids in certain countries might be tempremental, a power surge can damage your electronics. Some models will include a surge protector, this will protect your device from being overpowered.
  • It could potentially be of use domestically.
  • US and Canadian power strips include Type A, B, D, E/F, G, H, I, L and N plug adapters so should work in Hong Kong.

Disadvantages of a travel power strip

  • Unlike dedicated power converters, the conversion on travel power strips doesn't support high wattage appliances such as hair dryers or clothes irons.
  • Because of the size of a travel power strip it might be unsuitable for hand luggage.
  • A travel power strip might be excessive if you only bring a small number of appliances and devices which need charging. [8] [AD]
Power Plug Adapters

An easy to use Type G plug adapter

Power Plug Adapters

Benefits of a power plug adapter

  • Using a Type G power adapter will be ideal for Hong Kong.
  • Simple to use.
  • Affordable.
  • Light and small.

Disadvantages of a power plug adapter

  • Should you plan on travelling to more than one country you may need to bring along more than one type of power adapter.
  • This adapter only modifies the actual shape of the plug to fit in a Type G Hong Kong power outlet and not the voltage used in Hong Kong. So if your appliance doesn't support a 220 volt power outlet and isn't dual voltage you will still need to pack a voltage converter.
  • 1 plug adapter per device - for each separate appliance you'll also need to use a separate power plug adapter.
  • Your accomodation in Hong Kong may only have one power outlet, therefore you'll only be able to charge a single device at once.
  • You'll also still need to bring a separate USB charger as well if you need to power any USB device. [3] [AD]
Plug Adapter Sets

Plug adapter sets

Plug Adapter Sets

Benefits of a plug adapter set

  • An adapter set works out more cost-effective than purchasing multiple individual plug adapters for multiple trips.
  • Ensures you are covered for every eventuality and not just a Hong Kong power outlet.
  • Suitable if you are travelling to multiple countries.
  • Includes Type A, B, C, D, E/F, G, H, I, J, L, M and N adapters so will operate in Hong Kong.

Disadvantages of a plug adapter set

  • Will involve planning - prior to any trip you will need to choose which adapters to bring in advance, if you don't know every country you'll be visiting you'll need to bring every power adapter type with you.
  • Lots individual adapters to bring.
  • With just a single compatible power adapter working in Hong Kong the remaining power adapters will be redundant and using up space.
  • Not all power adapter types are typically included with the set (especially the less common adapters) - so ensure that your set has one that is compatible in Hong Kong.
  • Only changes the shape of the plug to fit in a Hong Kong power outlet but not the actual voltage. [9] [AD]
Voltage Converters

Larger voltage converters

Voltage Converters

Benefits of a voltage converter

Disadvantages of a voltage converter

  • A power converter only converts the 220 volts from a Hong Kong power outlet and not the actual shape of the plug to slot in a Hong Kong power outlet, therefore you'll still be required to bring the right type of power adapter for Hong Kong.
  • The size and weight of most models of voltage converters makes them too heavy for carrying in hand baggage.
  • Redundant when get back from Hong Kong.
  • Often better value and more practical to bring a dual voltage travel appliance than to buy a more expensive power converter just in order to bring your existing single voltage domestic appliance in Hong Kong.
  • If you are travelling to Hong Kong from America you will require a power converter as the voltage from a Hong Kong power outlet is 220 volts.

Hong Kong power outlets and plug sockets

What plug sockets are used in Hong Kong?

Type G power sockets are used in Hong Kong. You can identify the power outlet by the three rectangular slots forming a triangle pattern for live, neutral and ground. [3] [AD]

What plug sockets are used in Hong Kong?

Do US plugs work in Hong Kong?

No; an American plug won't work in Hong Kong because it can't fit in a Hong Kong power outlet without using a plug adapter. The voltage is different so you will need to use a power converter for Hong Kong if your charger or appliance isn't dual voltage and check that your device is compatible with a 50hz power outlet.

How do I use a 110 volt appliance in Hong Kong?

A step down power converter will allow you to use a 110V or 120V appliance in a Hong Kong power outlet.

Is the voltage in Hong Kong the same as in the US?

The voltage in Hong Kong is 220 volts, whereas Americans use 120 volts. If your American appliance or power charger isn't dual voltage then you will need use a power converter for Hong Kong which allows a 120 volt US appliance to work with a 220 volt outlet.

Is a plug socket in Hong Kong the same as in the US?

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

What is the electrical frequency used in Hong Kong?

The frequency of the alternating current from a Hong Kong power outlet is 50 Hz. [11]

https://en.wikipedia.org/wiki/Mains_electricity_by_country

Is electricity reliable in Hong Kong?

Though stable electrical power can't be guaranteed, electricity in Hong Kong is reliable and there is no pattern of persistent power cuts.

Is there good access to power outlets in Hong Kong?

The population of Hong Kong has excellent access to electrical power throughout the country.

Should I pack a portable charger for Hong Kong?

While power cuts aren't regular and electricity is available to the entire population, travellers are still advised to bring a power bank to recharge their cell phone.

  • During a trip increased reliance on mobile phones for storing itineraries, taking pictures, social networks, sat nav and staying entertained could syphon off 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 adequate power to make an emergency call or being able to use a satellite navigation app to find your way back to accommodation.
  • Using a power bank in Hong Kong eases those concerns as it allows you to keep your smart phone fully powered without needing a wall charger.
  • Use at least a 10,000mAh portable charger which can supply enough energy to power around three full charging cycles whilst a 20,000mAh power bank should keep an average mobile phone charged for around 7 days.
  • As long as your laptop supports USB-C charging then bringing a portable charger for a laptop marked with PD (power delivery) that supplies 20Wh or more can be used to extend the battery life of that laptop in Hong Kong.
  • Please note that some airlines prohibit batteries on an aircraft that supply 100 Wh of power or more and must be kept in hand luggage only so please check ahead with the airline.
  • Consumer power banks aren't strong enough for use with high powered items that generate heat, although a rechargeable hair dryer or rechargeable cordless flat iron can be used for travelling.    [4] [12] [13] [14] [15] [16] [AD]

How well do solar chargers work in Hong Kong?

Solar backpacks are ideal in hot countries

How well do solar chargers work in Hong Kong?

The daylight in Hong Kong should be suitable enough to charge solar power bank dependably, but will need to be exposed to strong daylight in order to produce suitable power for a single charge cycle. It might prove inconvenient to constantly unpack a solar power bank and wait whilst it recharges in sunny spells.

  • Instead, the larger solar panels used on a solar backpack give the backpack the ability to create more power within a shorter period of time and might still generate power when overcast, meaning they should perform well in Hong Kong.
  • Phones that have been directly plugged into a USB charging port of a backpack will trickle charge the power during sunny periods in Hong Kong, but could be inconvenient to have it constantly connected to the bag during the day if it is to be needed frequently. A regular power bank plugged into a solar backpack can be continuously recharged inside the bag during the day, afterwards the phone can be recharged from the power bank without needing the bag.
  • Even though the climate in Hong Kong is suitable for solar, a bag should have a solar cell efficiency of 22% or greater, be able to generate a minimum of 6 watts of energy and includes a compatible power bank of 10,000mAH or greater. Unlike normal firm solar cells, the flexible and durable cells used in solar powered bags are made to survive bending and scratching. They are available in laptop messenger, rucksack and backpack styles which makes them ideal for work, travel and domestic use.  [4] [17] [18] [AD]

Hong Kong 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 Hong Kong?

When travelling with more than just one device and visiting multiple countries then the best travel charger for Hong Kong to buy is a multiple USB adapter which includes compatible plugs like a 4 port USB travel charger.

Because these types of chargers are supplied with interchangeable plugs and can handle 100 volts - 240 volts it makes them ideal for over 100 countries around the world just by switching the supplied plugs over. If your device can support Fast Charge (not all USB devices will) then you will benefit from faster charging times by using one of these travel chargers, plus additional support for certain power hungry devices.

Unlike other adapters this means you can recharge multiple devices at the same time without needing to pack individual power chargers or occupying additional power sockets. Because you are only packing a single lightweight travel charger will also keep the size and weight down, making it perfect to fold up in hand baggage and on hand for recharging your devices at the airport or on your flight. Due to their space saving versatility these types of chargers can be used when back at home so when you’re not travelling they can be used under your bedside table charging multiple phones and tablets without needing an additional plug socket.

We suggest searching for a versatile power charger of this nature at your preferred electronics retailer. The travel charger illustrated below is the universal multi-device USB wall charger which has been successfully tested with multiple USB devices in numerous foreign countries. [6] [AD]

What USB charger do I need for Hong Kong?

Why use a travel USB charger for Hong Kong?

  • Normal travel USB chargers include multiple USB charger ports, this means that you only need to bring a single charger to charge multiple devices. Rather than bring 4 separate power chargers it's now only necessary to pack a single 4 port USB wall charger to power up to 4 individual devices which cuts down on the size and weight of your luggage.
  • Most travel USB power chargers should include interchangeable plug heads for various regions. This is perfect when visiting multiple countries which are likely to use different outlets to Hong Kong.
  • A good USB charger is compact, rugged and lightweight; ideal for rigors of travel instead of than risking packing a domestic charger which might be impossible to replace in Hong Kong.
  • USB chargers can accept the 220 volts used in Hong Kong power outlets plus other voltage standards across the world.
  • There is a possibility that some hotel rooms in Hong Kong might only have one wall outlet, by bringing a travel charger with multiple USB ports means you can share the single wall outlet with family or other traveler instead of having to wait to recharge one device at a time.
  • Because of their versatile nature a travel USB charger takes the worry out of visiting an unknown country as they are guaranteed to work practically anywhere on the planet.
  • Power outlets found in airports are often scant and the demand for charging multiple devices 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 cell phone in Hong Kong could prove to be problematic and costly.
  • Higher priced USB travel chargers should also incorporate a power outlet strip to plug in low wattage devices such as laptops, but be aware these will be unsuitable for high wattage domestic such as hair dryers or clothes irons. Please read the section on using travel appliances with a Hong Kong power outlet for useful guidelines on the most suitable power adapter for using a high wattage appliances with a Hong Kong power outlet.
  • Some tablets and cellphones could pull more than the normal 500 mA (milliamps) supplied by a standard 5 volt USB adapter to charge or provide fast charge. Higher priced USB travel chargers will support fast charging should some of your devices draw extra power.
  • On returning home travel USB power chargers can also be used by recharging multiple cellphones and tablets on an overnight basis using a single power outlet. [6] [AD]

What is the best USB charger for Hong Kong?

A 4 port USB travel charger is the most compact option for travellers from any country wanting to charge devices using USB, however for visitors also wishing to use their domestic plugs the following power strips provide larger but more versatile solutions. All 3 power strips offer surge protection which can be useful for visitors of counties with unstable power supplies. These travel adapters are supplied with interchangeable type C, I and G plugs covering both Hong Kong 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 Hong Kong.

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 perfect for most travellers from around the world visiting Hong Kong. [6] [AD]

Power converters for Hong Kong

What does a power converter for Hong Kong do?

Power converters allow travellers to use a 100, 110 or 120 volt electric device with a 220 volt Hong Kong power outlet.

Also known as: electrical converter, electrical transformer, voltage converter, power transformer or voltage transformer.

What is the difference between a plug adapter and a power converter for Hong Kong?

A cheap, small and lightweight power adapter (or plug adapter) will change the shape of the plug on your device to fit into a power outlet in Hong Kong, but an expensive and bulkier power converter converts the voltage of 220 volts from a Hong Kong power outlet to work with a non-220 volt device. [10] [AD]

Do I need a power converter for Hong Kong?

When travelling to Hong Kong from a different country please double check the device will accept a 220 volt power supply.

  • A step down power converter is needed if you are visiting Hong Kong from a country that uses 100-120 volts and your device or appliance isn't compatible with 220 volts. See our list of world power outlets guide to find out the voltage your country uses.
  • You shouldn't need a power converter if you already own either a 220 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 220 volts run the risk of an electrical fire hazard, blowing a fuse or damage to your device unless a step down power converter is used.
  • You don't need a converter if you are attempting to power a smaller electrical device such as a mobile phone or laptop as these are typically designed for international use and support dual voltage, however always always check the device for dual voltage support prior to your journey.
  • When supplying power to high wattage appliances or generate heat (for example clothes irons or hair dryers) then you will need to use a bulkier higher wattage heavy duty power converter to allow it to be used with a 220 volt Hong Kong power outlet.
  • It will be more cost effective to purchase a robust lightweight dual voltage travel appliance than trying to bring a much heavier power converter to Hong Kong simply to use your existing domestic appliance.
  • For more information read our comprehensive guides on how to use clothes irons, curling wands, hairdryers and hair straighteners in Hong Kong power outlets , along with recommendations on affordable dual voltage alternatives.  [10] [19] [AD]

Will I need a power converter for Hong Kong if I'm visiting from America?

The voltage from a wall outlet in Hong Kong is different to a 110 volt US outlet so please use a step down power converter if your charger or appliance doesn't support dual voltage. [10] [AD]

What converter do I need for Hong Kong?

You need to use a step down power converter to use any 100-120 volt appliance in a 220 volt Hong Kong power outlet. [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 Hong Kong 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 Hong Kong before plugging that into a Hong Kong 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 Hong Kong power outlet. [10] [AD]

What voltage does Hong Kong use?

Hong Kong uses 220 volts in their standard power outlets. [2]

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

Voltage converter

What is the difference between a 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.
What voltage is my device?

Dual voltage hair dryer

What voltage is my device?

The best way to see if your appliance is dual voltage is to check for numbers printed on the existing power adapter, or on the unit itself, normally on the rear of the unit or near to where the power cord plugs into. This location will depend on the make or model of your appliance and could also be written in the instruction manual or on the box.

  • Single voltage devices might say a specific number - such as 240V.
  • Single voltage devices might also have a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 220-240V.
  • Dual voltage devices will typically say a large range separated with a slash - such as 110/240V.

Substantiations

See the power adapter substantions section for more information on how we compared travel adapters.

What type of adapter do you need for Hong Kong?

Which type of adapter will you need to bring to Hong Kong?

The type of power converter which is suitable for Hong Kong is dependant on your requirements. Before deciding the right one to bring we recommend using the following checklist:

What different types of devices do you need to charge?

  • There are 3 different types of electrical items:
    • Low wattage electronic devices that can be plugged into an electrical outlet - for example cameras or laptops.
    • High wattage electrical appliances that can be plugged into an electrical outlet - for example curling irons and hair straighteners.
    • USB electrical devices that can be plugged into a USB port - for example phones.
  • Should you only intend to bring along just USB powered devices then a travel USB wall charger is ideal because you'll only have to bring that single lightweight charger rather than having to pack numerous domestic chargers.
  • A travel power strip is made for powering and converting voltage for many low wattage devices (such as cameras), but unsuitable for high wattage appliances which need voltage conversion and could potentially overload it.
How many devices will you be taking to Hong Kong?

Family may need to power devices too

How many devices will you be taking to Hong Kong?
