Plugs and Electricity in Vietnam: Sockets, Voltage and Adapters

What to plug in, and what to plug it into

Vietnam is easy to power up. Sockets are mainly Type A and Type C, the supply is 220 V at 50 Hz, and the same standard applies in every region of the country. If you live in continental Europe, your usual plugs will most likely fit. If you come from the United Kingdom or the United States, you need a small adapter. And whatever your origin, the one thing worth checking before you plug anything in is whether the device accepts 220 V.

That is the whole question this page answers. It is deliberately narrow: plugs, voltage, adapters. Clothes, medication and the rest of the suitcase belong to the Vietnam packing list, and the wider preparation is covered in the first-time visitor guide.

What	Vietnam
Socket types	Mainly Type A and Type C
Voltage	220 V
Frequency	50 Hz
Same in north, centre and south?	Yes, one national standard
Continental European plugs	Usually fit
UK and US plugs	Adapter needed

The two socket types, explained

You do not need to know the letters to travel, but they help when you shop for an adapter, because adapters are sold and described by them.

Type A is the two-pin plug with flat, parallel blades. It is the familiar North American shape, and it is also common in Japan. If your phone or laptop charger has two flat prongs, it is a Type A plug.

Type C is the two-pin plug with two round pins, often called the Europlug. It is the shape found on small chargers, shavers and slim power bricks all over Europe, and it is also used in many other regions. A Type C plug is thin and flat-bodied, with no earth pin.

Many sockets in Vietnam are made to accept both shapes, so you will often find one outlet that takes a flat-bladed plug and a round-pinned plug alike. Others take only one. The practical consequence is simple: if your plug is a plain two-pin plug of either kind, there is a good chance it goes straight in. If it has three pins, a bulky square body or an earth contact, it probably does not.

Which visitors need an adapter

The following is a general guide by country of origin. Plugs vary, so look at the actual shape of your own charger rather than relying on the country alone.

Continental Europe

Most continental European plugs fit without an adapter. The slim two-round-pin plug is a Type C and goes in directly. The larger round plug with side earth clips, used in Germany and many neighbours, usually fits as well, because it is built on the same two round pins. The French variant with a hole for an earth pin usually fits too. In practice, a traveller from France, Germany, Italy, Spain or the Netherlands can expect to plug in with no extra equipment.

“Usually” is the honest word. A socket can be recessed, which makes a wide plug body hard to seat, and the odd outlet may be loose or worn. A small, slim charger is the most reliable choice.

The United Kingdom and Ireland

The British three-pin plug does not fit. You need an adapter, and this is the case for every device you want to charge, including laptops, camera chargers and hair tools. Many British travellers are caught out here, because their phones and laptops handle 220 V perfectly well, so the only missing item is the adapter itself.

The United States and Canada

North American two-pin plugs are Type A, so the shape often fits. The grounded three-pin plug, with its round earth pin, does not, and you will need an adapter or a plug-converter for it. Many travellers from the United States therefore carry one adapter anyway, to cover their laptop. The more important question for them is voltage, covered in the next section, because North American mains is a lower voltage and some devices are built only for that.

Australia, New Zealand and elsewhere

Australian and New Zealand plugs, with their angled flat blades, do not match either of the main Vietnamese shapes, so you should bring an adapter. The same goes for any plug that is not a plain two-pin: look at yours, count the pins, and when in doubt, bring a universal adapter.

A simple test at home

Before you leave, take every plug you intend to bring and compare it with these two pictures in your mind: two flat blades, or two thin round pins. If it matches either, you are likely fine. If it matches neither, or has a third pin, add an adapter to the list.

Voltage: the check that actually matters

A plug adapter is a shape change. It does nothing to the electricity. Vietnam’s supply is 220 V, and a device built for a lower voltage that is plugged straight in can be damaged, so this is the part that deserves two minutes of your attention.

Read the label

Every charger and power brick carries a small printed label with the word Input. Look for something like this:

• Input: 100-240 V, 50/60 Hz. This is a wide-range, or “universal”, input. It works in Vietnam with only a plug adapter, where needed.
• Input: 220-240 V. Also fine for Vietnam.
• Input: 120 V only, or a single low voltage with no range. This device is not meant for 220 V. Do not plug it in without a voltage converter.

Most modern electronics for travel are wide-range: phone chargers, tablet chargers, laptop power supplies, camera battery chargers, e-readers, portable speakers and most USB charging bricks. Nearly everyone’s essential electronics fall in that group, which is why most visitors never need anything beyond a plug adapter.

Devices that are often single-voltage

The devices that trip people up are the ones that heat or spin rather than charge:

• hair dryers and straighteners;
• travel irons and steamers;
• electric kettles and immersion heaters;
• some electric razors and trimmers;
• certain appliances bought for home use in another country.

Some of these are dual-voltage and have a small switch or a label that says so. Others are single-voltage. If the label lists only one voltage, check it against 220 V. If it does not match, either leave the item at home, use the one provided by your hotel, or buy a cheap replacement locally.

Why converters are not a first choice

A voltage converter or transformer exists to step 220 V down to 120 V, so that a single-voltage device can run. They are heavy and bulky, and they are rated for a certain wattage; a hair dryer draws far more than a phone charger, so a converter small enough for the suitcase is often too weak for it. For short trips it is almost always easier to travel without that device, or to buy a dual-voltage model.

What about 50 Hz?

The frequency is 50 Hz. Wide-range chargers list “50/60 Hz” and are not affected by the difference. The only gadgets where frequency can matter are older appliances with motors or clocks, which are unlikely to be in your carry-on. If your device label lists 50 Hz or a 50-60 Hz range, you are fine.

Choosing an adapter that will not let you down

One universal adapter versus several small ones

A single universal adapter that covers several plug shapes is the simplest solution, and it is useful on later trips to other countries. A pair of small single-purpose adapters is lighter and often more reliable, since a loose universal may sag out of a socket with a heavy charger attached. If you are travelling with a partner, family or friends, one adapter per person is better than one shared adapter; charging in the evening is a classic crunch point.

Look for USB ports

A compact adapter with built-in USB ports can charge two or three phones from a single outlet, which is the real pinch point in a hotel room with few sockets. Check the rated output on the label, and make sure the adapter is marked for 220 V input, since cheap ones sometimes are not.

A short extension strip

If you carry a laptop, a camera, a phone and a power bank, a small multi-way strip with a single adapter at the end turns one outlet into four. It is heavier than an adapter, but it saves reshuffling cables every night. Be sure it is rated for the voltage, and do not overload it with several high-draw items such as hair tools.

Buy before you travel

You can find adapters in electronics shops and some convenience stores in Vietnamese cities, and some hotels keep a few to lend. But if you land in the evening with a phone at 5 per cent, the least stressful thing is to have your adapter already in your hand luggage. Put it in your carry-on, not your checked bag.

Power banks

A power bank is useful on long travel days, and it works with whichever adapter you use, since it charges through USB. Airlines set rules about carrying power banks, which generally require them to travel in the cabin, not in checked luggage. Check your airline’s guidance before you fly.

The same everywhere in the country

Vietnam stretches roughly 1,650 km from the Chinese border to the Mekong Delta, and the electricity standard is the same along its entire length. The plugs and the voltage that you find in a Hanoi guesthouse are the same as those in a Hoi An homestay or a Ho Chi Minh City hotel. There is no regional variation to plan around, so a single adapter and a single set of chargers will serve you from the north through the centre to the south.

What does vary is how many sockets a given room has, where they are placed, and what types they are. A modern hotel in Hanoi or Ho Chi Minh City is likely to have several outlets, often with a mix of types. A rural homestay, a simple guesthouse or a boat cabin may have fewer. That is not a sign of a different standard; it is simply a smaller building. A short multi-way strip handles the difference.

On the road, on the water, in the mountains

The best habit is simple: top up devices whenever you are at an outlet, rather than waiting until you are low.

• Cruises. Overnight boats on Ha Long and Lan Ha bays offer cabins with sockets, but how many and what type depends on the vessel, so it is sensible to ask the operator beforehand and bring a short strip. On a trip such as an overnight cruise on Lan Ha Bay, you will want your phone and camera fully charged before boarding, because you will spend most of the time on deck rather than at an outlet. The overnight cruise guide explains the format of these trips.
• Mountain homestays. In the northern hills, a homestay is likely to be a simple house with a few sockets for the whole group. If you are walking with a company on a trip like a two-day trek through the Ta Van and Lao Chai rice terraces, bring a power bank and arrive with devices charged, and be prepared to share. The homestays guide goes into what to expect.
• Long days out. On full-day outings, such as a day trip from Hanoi to Ninh Binh, a phone is both your camera and your map, and it drains faster with the screen and mobile data on. A small power bank in the day bag is the answer, not an adapter.
• Trains, buses and cars. Do not count on finding a socket at your seat on every journey. Charge before departure, and keep a power bank in the bag you carry on with you. The getting around Vietnam guide has the transport details.

Phones, data and everything else

Your phone is the device that you will charge most often, so make sure its charger and cable are in order. If you plan to use a local data plan, the eSIM and SIM card guide explains the options. A phone with an eSIM does not need a separate SIM tool, which is one less small item to carry, but it does use the battery more while it searches for a network, so a power bank is useful regardless.

A checklist before you leave

Here is the short version, in the order you should do it.

1. Count your plugs. Lay out every charger you plan to bring.
2. Check the shape. Two flat blades or two round pins fit; three pins, or a different shape, needs an adapter.
3. Read each label. Look for an input of 100-240 V, or at least 220 V.
4. Drop single-voltage items. Leave behind or replace any hair or heating device that is not rated for 220 V.
5. Pack one adapter per traveller. Plus a short strip if you carry many devices.
6. Put the adapter in your hand luggage. So you can charge on arrival.
7. Bring a power bank. In the cabin bag, not the hold.

What this page does not cover

This page is about plugs and voltage only. For what to wear, what to do about the weather, and what else to put in the suitcase, use the packing list guide or the interactive packing list tool. For a broad overview of the practical points that matter before a first trip, the travel essentials tool and the post on things to know before visiting Vietnam are good places to continue.

If you are planning where to sleep, the where to stay in Vietnam guide is the natural next step, and a long day on the Perfume River or the Imperial City, such as a full-day imperial city tour from Da Nang, is one more good reason to start the morning with a full battery.

Plugs and electricity in Vietnam: common questions

What type of plug does Vietnam use?

Sockets are mainly Type A (two flat pins) and Type C (two round pins). Many sockets are built to take both shapes, so a plug of either kind usually goes in.

What is the voltage in Vietnam?

The supply is 220 V at 50 Hz. This is the same in the north, the centre and the south, in cities as well as in the countryside.

Do I need an adapter for Vietnam?

Visitors from continental Europe can usually plug in directly, because their two-pin plugs fit Type C sockets. Visitors from the United Kingdom and the United States should pack an adapter, and so should anyone whose plug has three pins or an unusual shape.

Can I use my American devices in Vietnam?

Only if the device is rated for 220 V. Most phone, laptop and camera chargers are, and say so on the label. Devices marked 120 V only, such as many hair dryers, can be damaged and need a voltage converter or should stay at home.

Will a plug adapter change the voltage?

No. An adapter only changes the shape of the plug so that it fits the socket. It does nothing to the voltage, so the device itself must accept 220 V.

Is the electricity different in Hanoi, Hoi An or Ho Chi Minh City?

No. The standard is national, so the same plugs, voltage and frequency apply in Hanoi, Hoi An, Ho Chi Minh City, Phu Quoc and everywhere in between.

Should I buy an adapter before I travel or in Vietnam?

Buying before you leave is the safer choice, because you can charge your devices on the first night. Adapters are also sold in Vietnamese electronics shops, and some hotels keep a few to lend, but you should not rely on that.
