Vietnam outlet plug: socket types, voltage and adapters
Vietnam uses Type A, B, and C plugs and sockets, at 220 V / 50 Hz. If you travel from the US, Canada, UK, or Australia, you need a plug adapter. Some European Type C plugs fit directly, but socket and grounding compatibility can vary. Many modern electronics, including phones and laptops, accept 100-240 V. Check the charger label before plugging it in.

What plug types does Vietnam use?
Vietnam commonly uses Type A, B, and C sockets, at 220 V / 50 Hz. Which type you find often depends on the building's age: older shophouses were typically wired with Type A only, while newer hotels and malls increasingly install universal sockets that accept several plug types without an adapter.
Type A and Type C: what you'll see most
Type A has two flat parallel blades and is used in the US, Canada, and Japan. Type C has two round pins and is common across Europe and many parts of Asia. Some Vietnamese hotels use sockets that accept both A and C without needing to switch adapters.
Type B and grounded sockets
Type B has two round pins plus a third rectangular grounding pin. It is the least common of the three in everyday hotel rooms, but it shows up in newer buildings and on higher-power outlets built to the current national wiring standard, TCVN 6188-1:2007. If a socket has three holes instead of two, it is grounded, which matters for laptop chargers and other three-prong plugs. Do not rely on Type G sockets being available.
Amperage and what trips the breaker
Bring a universal travel adapter covering Type A, B, and C. It costs around 50,000-150,000 VND at airports and convenience stores (checked September 2026). Most Vietnamese household sockets are rated for 10 A at 220 V, with some newer buildings wired to 16 A (TCVN 6188-1:2007). Running a hair dryer, a kettle, and a phone charger off the same power strip in an older guesthouse can trip the circuit breaker. If a room suddenly loses power, check the breaker panel first, often near the door or in a hallway closet, before assuming the whole building or area lost electricity.
Skip assuming one plug type covers the whole trip. Older shophouses and budget guesthouses, especially in areas like Hanoi's Old Quarter, may only have Type A sockets, so a universal adapter is worth the extra weight even when your home plug technically fits some rooms.
What voltage does Vietnam use?
Vietnam's mains supply is 220 V / 50 Hz (Vietnam national technical standard TCVN 7417:2010, confirmed by EVN, checked September 2026). The US, Canada, and Mexico use 120 V / 60 Hz, and Japan uses 100 V / 60 Hz, so check the device label before plugging in.
Why a US, Canada, or Japan charger can be at risk
A device rated for 120 V only can be damaged by a 220 V supply.
Dual-voltage devices: check the label first
Many modern phone chargers, laptop power bricks, and camera chargers are dual-voltage, often rated for 100-240 V, 50/60 Hz. Check the small print on the charger body itself. If it says "100-240 V", you need nothing more than a plug shape adapter. No voltage converter is needed for a device rated for 100-240 V.
Skip guessing based on the plug shape alone. A Type C adapter lets a European charger physically plug in, but the device still needs to accept 220 V, so always check the input rating printed on the charger before assuming it is safe to use.
Do I need an adapter for Vietnam?
It depends on where you travel from. US, UK, and Australian plugs do not fit Vietnamese sockets, so you need an adapter. European and Japanese plugs usually fit directly.
US, UK, and Australia: bring an adapter
US and Canada: Yes. Your Type A plug fits some Vietnam sockets, but many rooms, especially budget guesthouses, only have recessed Type C panels. A universal adapter is the safer choice.
UK and Ireland: Yes. Type G (three rectangular pins) is not a standard Vietnamese plug type. Bring an adapter.
Australia and New Zealand: Yes. Type I (two or three angled blades) does not fit Vietnamese sockets.
EU, Japan, and onward travel in Southeast Asia
EU (Germany, France, Spain, Italy, etc.): Usually no. Type C plugs fit Type C sockets. A universal adapter is still worth carrying in case a room only has Type A outlets.
Japan: Usually no adapter needed for plugs, Type A fits. But Japanese devices rated for 100 V only will need a voltage converter. Check the device label before plugging in.
Continuing to Cambodia, Laos, or Thailand: The same Type A/C adapter that covers Vietnam also works in Cambodia (Type A, C, and G) and Thailand (Type A, C, and the hybrid Type O). Laos uses Type A, B, C, E, and F, so a universal adapter is the safer pick if your route includes Laos.
Both Hanoi and Ho Chi Minh City follow the same electrical standard, socket types and voltage are identical across Vietnam regardless of which city you visit.
Traveling with medical equipment that must stay charged
Most hotel listings on Agoda, Booking.com, or local Vietnamese booking sites do not list socket type. If you are traveling with equipment that must stay charged, a CPAP machine, an insulin cooler, or another medical device, email the property directly to confirm both the plug type and whether backup power is available during an outage.
Skip assuming an EU or Japanese plug means no adapter is ever needed. Type C fits Vietnamese sockets, but Japanese devices rated for 100 V only still need a voltage converter even though the plug shape fits, so the plug matching is not the same as the device being safe to use.
Do I need a voltage converter?
Usually no, if your device supports the local voltage. A voltage converter changes the actual voltage level (e.g. 220 V down to 120 V), while a plug adapter only changes the shape of the connector. They are different products, and almost every modern phone or laptop charger only needs the second one.
Voltage converter vs plug adapter: check the label
Check the label on your charger or power supply. If it reads "Input: 100-240 V ~ 50/60 Hz", it is dual voltage, you only need a suitable plug adapter. Always check the actual input rating on your device rather than guessing from the plug shape.
Devices that actually need a converter
The only devices that commonly require a voltage converter are older single-voltage appliances: hair dryers, electric shavers, and curling irons rated "120 V / 60 Hz only". If you bring one, you need a step-down converter, or buy a local appliance for the trip. Local step-down converters cost roughly 150,000-300,000 VND at Vietnamese electronics shops (checked September 2026).
Power cuts: how common, and what to pack as backup
Power cuts are uncommon in major cities and most 3-star-and-up hotels recover quickly, often with backup power for common areas. Smaller guesthouses and rural homestays are more exposed, especially during the rainy season, when a short outage after heavy rain is more likely. Packing a charged power bank is a cheap backup if you are staying somewhere off the main grid for a night or two.
Skip buying a voltage converter unless you are packing an old single-voltage hair dryer, shaver, or curling iron. Nearly every modern phone, laptop, and camera charger already reads 100-240 V on the label, so a converter you did not need is 150,000-300,000 VND wasted.
Where to buy an adapter in Vietnam
You do not need to bring an adapter from home. Basic universal adapters are sold across Vietnam, from airport arrival halls to neighborhood convenience stores and electronics markets in both Hanoi and Ho Chi Minh City.
Airport arrival halls
Airport arrival halls: Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), and Da Nang airports sell basic universal adapters for around 80,000-150,000 VND, a premium over city prices.
Convenience stores and supermarkets
Convenience stores: Circle K, WinMart+, and GS25 branches stock basic adapters for around 50,000-100,000 VND. Supermarkets: large chains such as Coopmart, WinMart, and Lotte Mart also stock basic adapters and power strips in their electronics aisle.
Hanoi and Ho Chi Minh City electronics districts
Hanoi electronics district: Luong Van Can Street, in the Old Quarter (Hoan Kiem district), has many small shops selling household and travel items, easy to combine with sightseeing. Ho Chi Minh City: Ben Thanh Market (District 1) and the Nhat Tao electronics market (District 10) both sell adapters and power accessories.
Skip paying airport prices if you will be in a city center within a day. Airport adapters run 80,000-150,000 VND, a real premium over the 50,000-100,000 VND a convenience store charges just a few kilometers away.
Pack one power strip instead of multiple adapters
If you travel with a phone, laptop, and camera, a universal travel power strip is more practical than three separate adapters, since everything charges from a single wall socket instead of several.
How the one-adapter setup works
Buy one universal adapter (at the airport or a convenience store), then plug a travel power strip into it. The strip gives you two or three additional sockets, Type A, C, or universal, plus USB-A and USB-C ports.
Check the label for worldwide use
Prices for compact travel power strips vary by brand and features. Look for "Input: 100-240 V" on the label so it works anywhere in the world, not just in Vietnam.
Wattage limits: what not to plug in together
Most compact travel power strips are rated around 500-750 W combined, plenty for phones, cameras, and tablets charging at once, but a full-size laptop charger and a hair dryer together can push past that limit. For more practical things to know before landing, our Vietnam fun facts guide covers currency, transport, tipping customs, and 20 other things that surprise first-time visitors.
Skip plugging a hair dryer into the travel strip; send high-wattage items straight into the wall adapter instead, since the strip's 500-750 W combined rating is lower than you might assume.
Sorting out your adapter is one less thing to worry about on arrival. If you want to see more of the region once you land, our Hanoi and Ha Long Bay tour covers Hanoi's Old Quarter and a day cruise through Ha Long Bay's limestone karsts.
