Plugs & Sockets in Vietnam: Which Travel Adapter Do You Need?

What type of plug is used in Vietnam?

Vietnam uses Type A and Type C plugs. Most sockets are hybrids that take both two flat pins (Type A, as in the US) and two round pins (Type C, as in continental Europe). Some add a round earth hole for three-prong Type B plugs, and Type F plugs usually fit the round holes.

Other guides list types A, C, D, F or even G, and here is why they never match. The national standard, TCVN 6190:1999, covers flat and round two-pin plugs, versions of both with a round earth pin, and "multipurpose" sockets that accept them all. Plug charts then add whatever else happens to fit. What matters to you is whether your own plug goes in:

What do wall sockets in Vietnam actually look like?

In my experience, the socket you will use most often, whether in a city hotel, a family homestay or a café, is a simple two-hole hybrid: each hole is a flat slot widened into a circle, so flat and round pins both slide in. Newer buildings often add a round earth hole, and many extension strips sold in Vietnam carry "universal" sockets that take almost any plug. Three things I tell every guest:

• Fit matters more than shape. Slim round Europlug pins can sit loosely in worn sockets, and a heavy charger may slowly slide out. If the connection feels weak, use another socket or a power strip.
• Do not assume the third hole is earthed. In older buildings and many homes it is not connected to anything, so treat every socket as a two-pin, unearthed outlet.
• Never force a plug. If it only goes in with bending or twisting, it is the wrong plug for that socket. Use an adapter.

What type of plugs are used in hotels in Vietnam?

Hotels in Vietnam mostly use the same hybrid sockets that take flat Type A and round Type C plugs. Some hotels, especially newer ones, also have a universal socket or USB charging ports in the room, but budget guesthouses and rural homestays usually have only basic two-pin hybrids, and fewer of them.

Vietnam's hotel rating standard, TCVN 4391:2015, also sets where the sockets go: hotels rated three stars and above must have one at the desk, and four- and five-star hotels one by the bed as well. If your plug is Type G or Type I, my advice is not to plan around the universal socket. There may be only one in the room, often in an awkward spot, and you are unlikely to find one in a village homestay. A small adapter solves the problem for a couple of dollars.

What plug adapter do I need for Vietnam?

You need an adapter only if your plug does not have two flat or two round pins. That means travellers from the UK, Ireland, Singapore, Malaysia, Hong Kong, Australia and New Zealand, anyone with an Indian or Italian three-pin plug, and Americans with three-prong plugs where there is no earth hole.

Are Vietnam plugs the same as in the US?

Partly. Vietnamese sockets take the US two-flat-pin plug (Type A) without an adapter, and some take three-prong Type B plugs too. The real difference is voltage: Vietnam runs on 220V, the US on 120V. Chargers labelled 100-240V are fine; anything rated 110-120V only needs a converter or should stay at home.

If your laptop brick has a three-prong cable, check whether it also came with a short two-pin head that clips onto the brick, and use that. If not, a 3-to-2 prong adapter saves you hunting for a socket with an earth hole in every room. Everything here applies to Canadian plugs too.

Is the Vietnam plug type the same as in Europe?

Mostly yes. The round two-pin Europlug (Type C) fits Vietnamese sockets, and German, Spanish and French plugs (Types F and E) usually go in too, although their wide bodies can struggle with recessed or closely spaced sockets. The voltage (220V against 230V at home) is compatible, so European devices need no converter.

The exception is Italy's three-pins-in-a-line Type L plug, which does not fit. Italian two-pin plugs are fine. Travellers from the UK and Ireland should read the Type G section below.

Is the Vietnam plug type the same as in India?

Partly. Most Indian phone chargers use two round pins (Type C) and fit Vietnamese sockets directly. Three-pin Type D and Type M plugs, common on laptop chargers and larger appliances, do not fit, so pack a small adapter for those. Voltage is not an issue: India runs on 230V and Vietnam on 220V.

Travelling from the UK, Ireland, Singapore, Malaysia or Hong Kong (Type G)

Your three rectangular pins will not go into a standard Vietnamese socket. Some hotels have a universal socket that accepts Type G, but I would not rely on it. What I suggest to UK guests is a compact UK-to-EU adapter (Type G to Type C) rather than a bulky universal block: it fits almost every socket here and costs very little. The voltage is in the same range as at home, so you do not need a converter.

Travelling from Australia or New Zealand (Type I)

Australian and New Zealand plugs, with their two angled flat pins, do not fit Vietnamese sockets, and outside hotels you will rarely find a socket that takes them. Bring an Australia-to-Type C adapter, or buy one after you land: they are sold in convenience stores and electronics shops in every city. Your devices already run on 230V, so no converter is needed.

What voltage and frequency does Vietnam use?

Vietnam uses 220V at 50Hz. Most phone, laptop, camera and tablet chargers are labelled INPUT 100-240V, 50/60Hz and work with just the right plug. Appliances rated 110-120V only, such as many US hair dryers, straighteners and some electric toothbrush chargers, can overheat or burn out on 220V.

Some websites still list "110/220V" or "230V" for Vietnam. The supply you will meet in hotels and homes is 220V, and anything built for 220-240V works normally. Apple, for example, rates its USB power adapters for 100-240V at 50-60Hz. Before you pack, read the small print on each charger or power brick and match it to this checklist:

Do I need a voltage converter or just a plug adapter for Vietnam?

Most travellers only need a plug adapter. An adapter changes the shape of your plug so it fits the socket; it does nothing to the electricity. A converter, or step-down transformer, lowers 220V to 110-120V, and you only need one for devices labelled 110-120V only.

Plug a 120V-only device into a 220V socket and it receives almost twice the voltage it was built for, so heating elements overheat and the device usually fails quickly, sometimes with smoke or a tripped breaker. Small travel converters are meant for low-wattage items, while a hair dryer typically draws 1,000W or more. The 50Hz frequency (60Hz in North America) makes no difference to modern chargers; only some older clocks and motor-driven appliances may run slightly slow.

Can I use my hair dryer in Vietnam?

Only if it is dual voltage or made for 220-240V. Check the label: "100-240V" or a 125V/250V switch means yes; "110V" or "120V" on its own means no. You may not need your own anyway: Vietnam's hotel rating standard requires a hair dryer in every room at three stars and above.

That rule sits in TCVN 4391:2015. According to figures published by the Vietnam National Authority of Tourism in October 2025, the country had 1,133 hotels rated three to five stars at the end of 2024, with 169,089 rooms: about three in every four rooms in Vietnam's star-rated hotels. Budget guesthouses and homestays fall outside that group, so if you are staying in those, a small dual-voltage travel dryer is lighter and cheaper than a heavy transformer.

What type of travel adapter do I need for Vietnam?

For Vietnam alone, a small single adapter that turns your plug into two round pins (Type C) is enough and fits almost every socket. If you will travel on to other countries, a compact universal adapter with USB-C ports is more practical. Americans with three-prong plugs just need a 3-to-2 prong adapter.

None of these change the voltage. Whichever you choose, look for a rating printed on the adapter (250V, 10A is typical) and, on universal models, a built-in fuse.

Plugs in Vietnam and Cambodia, Laos and Thailand: one adapter for the whole trip?

Yes, in most cases. Cambodia, Laos and Thailand run on 230V and, like Vietnam, mostly use hybrid sockets for flat and round two-pin plugs. Cambodia also has some UK-style Type G sockets, so for a multi-country trip a compact universal adapter is the safest single choice.

Forgot your adapter? Where to buy one in Vietnam

Ask at hotel reception first. It costs nothing, and some chains make lending official: Hyatt, for example, lists outlet adapters among the items guests can borrow at participating hotels under its Hyatt Has It programme. If your room has USB charging ports, your cable alone may be enough. Otherwise, adapters are easy to buy in any city or tourist town:

• Convenience stores and supermarkets (Circle K, Co.opmart, WinMart): basic adapters that are fine for phone chargers, and convenience stores stay open late. According to
• (updated April 2026), shop prices typically run 50,000-150,000 VND ($1.90-5.70).
• Electronics chains (Điện Máy Xanh, MediaMart): better quality and a clear rating. As an example, Điện Máy Xanh listed the Điện Quang TV-01 travel adapter at 90,000 VND (about $3.40) on 29 September 2026.
• Markets (Dong Xuan in Hanoi, Ben Thanh in Ho Chi Minh City): the cheapest option, but check the build quality and bargain.
• Airports: the most expensive option. The same Holafly guide puts airport prices at two to three times what an adapter costs online before you travel, so buy here only if you cannot wait.

Prices in US dollars use Vietcombank's selling rate of 26,170 VND to $1 on 29 September 2026.

Need more sockets? Buy a local power strip

Hotel rooms often have only one or two free sockets, and families run out fast. Do what locals do and buy a Lioa power strip: a three-socket model with universal sockets costs around 88,000-115,000 VND ($3.40-4.40) in supermarkets and electrical shops and takes almost any plug. If you travel with a 230V strip from Europe or Australia, a single adapter for that strip charges everything.

Charging on the road: buses, trains, power cuts and flights

In Hanoi, Ho Chi Minh City and Da Nang the power supply is generally reliable. In mountain areas such as Sapa, Ha Giang and Cao Bang, and during storms, short power cuts can happen, so I always suggest keeping a charged power bank in your day bag. Sleeper buses, limousine vans and many overnight trains have USB ports or sockets, but they do not always work and are often shared, so board with your phone and power bank already charged.

Conclusion

Before you pack, check two things: the shape of your plug and the INPUT line on each charger. Two flat or two round pins and 100-240V chargers mean you are ready as you are; anyone else needs one small adapter, and 110V-only hair tools should stay at home.
