What adapter do I need for Hong Kong?

You will need to use a Type G plug adapter [3] 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 plug adapter [3]. 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 plug 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 plug adapter otherwise you'll also need to bring a suitable plug adapter for Hong Kong.
  • 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 [4] if you want to keep your mobile phone charged throughout the day whilst visiting an unknown location.

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

What plug sockets are used in Hong Kong?

The type of power socket used in Hong Kong is type G. You can identify the power outlet by the three holes forming a triangle shape for live, neutral and earth.

What plug sockets are used in Hong Kong?

Do US plugs work in Hong Kong?

No - a US plug won't work in Hong Kong because it won't fit in a Hong Kong power outlet without using a power adapter. Also, the voltage is 220 volts therefore use a power converter for Hong Kong if your device or appliance isn't dual voltage and check that your appliance will work 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 appliance in Hong Kong.

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

The voltage in Hong Kong is 220 volts, however 120 volts is used in the US. If your US appliance or power charger won't handle dual voltage then you will need to use a suitable power converter for a Hong Kong power outlet which can change the voltage from a 220-240 volt power outlet to 120 volts.

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.

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 [4] 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 [4] which can supply enough energy to power around three full charging cycles whilst a 20,000mAh power bank [14] 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 [15] 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 [12] or gas hair straighteners [13] can be used for travelling.

How well do solar chargers work in Hong Kong?

Solar backpacks are ideal in hot weather

How well do solar chargers work in Hong Kong?

The daylight in Hong Kong should be suitable enough to charge solar power bank [17] 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 [16] 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 [4] 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.

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 [6].

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 4 Port USB Wall Charger [6] which has been successfully tested with multiple USB devices in numerous foreign countries.

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.

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 [18] converts the voltage of 220 volts from a Hong Kong power outlet to work with a non-220 volt device.

Do I need a power converter for Hong Kong?

If visiting Hong Kong from a different country please check the device can be used with a 220 volt power supply.

  • A step down power converter [10] is needed if you are visiting Hong Kong from a country that uses 100-120 volts and your device or appliance is incompatible with 220 volts. Read our list of world power outlets guide to see which voltage is used in your country.
  • You don't need a power converter if you already own either a single voltage appliance that works with 220 volts or one that is dual voltage.
  • Typically, electrical devices designed for a lower voltage (such as 120 volts) and then used with 220 volts run a risk of an electrical fire hazard, a blown fuse or damage to your device unless a step down power converter [10] is used.
  • You won't need a power converter if you wish to charge a smaller electrical device such as a tablet as these are normally designed for international use and support dual voltage, however you should always check the device for dual voltage support first.
  • For supplying power to high wattage appliances or generate heat (for example clothes irons or hair dryers) then you will need to use a much larger higher wattage heavy duty power converter [19] which allows the appliance 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 bringing a heavier high wattage power converter to Hong Kong simply to use your existing domestic appliance.
  • Read these comprehensive guides on how to use curling irons, clothes irons, hair dryers and hair straighteners in Hong Kong power outlets , along with recommendations on some affordable dual voltage alternatives.

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

The 220 volts from a power outlet in Hong Kong is different to a 110 volt US outlet, therefore you need to use a step down power converter [10] if your charger or appliance doesn't support dual voltage.

What converter do I need for Hong Kong?

To use any 100, 110 or 120 volt appliance with a 220 volt Hong Kong power outlet you will need to buy a step down power converter [10].

How to convert 220 volts to 110 volts

  1. Use a step down power converter [10] 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.

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?

One method to see if your appliance is either single or dual voltage is to check for numbers printed on the supplied charger, or on the device itself, normally near to where the power cord sits. This location will depend on the make or model of your device but should also be written in the instruction manual or on the box.

  • Single voltage devices might have a specific number - such as 120V.
  • 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 say a larger voltage range separated with a slash - such as 110/240V.

  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 Hong Kong?

Which type of electrical adapter to bring to Hong Kong

The type of power converter or plug adapter that is best to use in Hong Kong will depend on various requirements. Before choosing which adapter to use we suggest using this checklist:

What are the types of electrical items do you want to use with a Hong Kong power outlet?

Make a list of items to bring

What are the types of electrical items do you want to use with a Hong Kong power outlet?

  • There are three different types of electrical devices or appliances:
    • Low wattage electrical items which plug into a power outlet - for example a laptop.
    • High wattage appliances which plug into an electrical outlet - for example clothes irons or hair dryers.
    • 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 Hong Kong then a simple travel USB charger is perfect as you will only need to bring one charger with appropriate charging cables rather than packing multiple domestic chargers.
  • Travel power strips are perfect for providing power and voltage conversion for several low wattage devices of any voltage, but won't work with high wattage appliances (such as hair irons) which require voltage conversion, potentially overloading the power strip.
How many devices will you be taking to Hong Kong?

Family need to power electronics too

How many devices will you be taking to Hong Kong?

  • Try adding up how many items you intended on bringing with you to Hong Kong (such as tablets, laptops, cell phones, eReaders, hair dryers or clothes irons).
    • Remember to allow for more electrical devices at a later date. Do you intend on purchasing a new laptop computer soon?
    • There is an increasing amount of rechargeable electronics such as electric shavers that utilise a USB port as a power source. The if you buy a new device it might need a USB adapter so remember to ensure your travel adapter has enough spare ports to support these too.
  • Are you bringing family to Hong Kong that will need to charge their iPads?

  • Accommodation might only offer a single wall outlet. This will be a problem if charging batteries of multiple devices such as tablets, phones or laptops overnight as you can only recharge a single device at a time then need to keep swapping after each device has charged.
  • If you wish to charge more than one device simultaneously then look to packing a travel power strip or travel USB wall charger that can power multiple USB ports and power outlets.

How much can you afford?

  • A cheap power adapter starts at $7 which will charge one device from a Hong Kong power outlet (providing that works with 220 volts or it is dual voltage), but investing in around $20 means you can charge multiple devices at once and be able to use them in various different countries.

  • For long journeys think about bringing an appropriate charger which is ideal for airports that can be used with different power outlet types, one which is small enough to pack in carry-on luggage and can be used to top up tablets and phones.
  • As not all flights actually have power outlets for customers please consider bringing a battery portable charger [4] which will recharge on the go. After arriving you may need to use a phone to make a call, sending emails , using sat nav or viewing your itinerary; ensure that your phone has enough charge remaining.

  • Electricty in Hong Kong is generally stable however if you want to go to other countries you may need a power adapter which will protect your appliances. The power will often fluctuate in some areas which might possibly cause damage to your devices, you will need to use a power adapter which offers built in surge protection such as a travel power strip.
  • You can prepare for power cuts and countries with limited electrical coverage by using a solar backpack [16] or portable charger [4].
