Vietnam runs on 220V at 50Hz, and the wall sockets are a mix of flat-pin and round-pin designs. For most travellers the fix is a cheap universal adapter, but a few devices (hair dryers, travel kettles, some shavers) can be damaged if they are built for 110-120V only. This guide covers the plug types you will meet, how to check your gear, and where to buy an adapter if you forget one. Details are as of 2026.
Plug types and voltage at a glance
| Item | Vietnam standard |
|---|---|
| Voltage | 220V |
| Frequency | 50Hz |
| Plug types | A (two flat pins), C (two round pins), F (two round pins with side earth clips) |
| Typical socket | Multi-standard, accepts flat or round pins |
Type A is the same two-flat-pin plug used in the US and Japan. Type C is the thin two-round-pin βEuroplugβ used across continental Europe. Type F (Schuko) turns up in newer hotels, serviced apartments and condos. Because so many outlets are multi-standard, a US or European plug often fits without help, but the fit can be loose, especially with Type A plugs that have one wider pin.
Which plug do you need to bring?
- US, Canada, Japan (Type A/B): two-pin Type A plugs usually fit directly. Three-pin Type B plugs need an adapter, or a cheater plug that removes the earth pin.
- Continental Europe (Type C/F): Type C fits the round-pin sockets. Check chunky Type F plugs, which sometimes will not sit fully in older recessed outlets.
- UK and Ireland (Type G), Australia and New Zealand (Type I), China (Type I/A): you need an adapter. A universal model with a built-in cover for all four pin patterns is the simplest option.
- Singapore and Malaysia (Type G): adapter required.
We recommend a universal adapter with a fuse and at least one built-in USB-C port, so a single socket charges a phone and a laptop together. Packing a compact three-way extension strip helps when your room has only one working outlet.
Voltage: when you need a converter
Look at the small print on the charger or the device label. If it reads βINPUT: 100-240V, 50/60Hzβ, it is dual-voltage and works in Vietnam with only a plug adapter. This covers nearly all phone chargers, laptops, tablets, camera battery chargers, e-readers and power banks.
Single-voltage items rated 110-120V are the risk. Plugged into 220V without a converter they can overheat, blow a fuse or burn out. Typical examples are older hair dryers, curling irons, electric shavers and beard trimmers. Our advice is to leave these at home, buy a dual-voltage travel version, or buy a cheap one in Vietnam. A frequency mismatch (60Hz to 50Hz) matters mainly for devices with motors or clocks.
Travel kettles and immersion heaters draw a lot of power, and plug-in converters for them are heavy and unreliable. Most hotels supply a kettle, so skip packing one.
Power in hotels, hostels and homestays
Mid-range and upmarket hotels in Hanoi, Ho Chi Minh City and Da Nang usually provide several sockets plus bedside USB ports. Older guesthouses, mountain homestays and some hostel dorms may have one outlet per room, sometimes located far from the bed. In dorms, a short extension lead (about 1.5 m) makes a real difference, and a long phone cable is just as handy.
In Sapa, Ha Giang and other northern mountain areas, homestays may switch off the generator or reduce supply overnight, and mains power can drop during storms. Charge your devices and power banks whenever you reach a plugged-in room. Our Hanoi to Sapa train vs bus guide covers the overnight journey where a power bank is most useful, since sleeper trains and buses have limited charging points.
For remote workers, our Vietnam internet connectivity guide explains how to keep a laptop running during outages, and a local data plan from our Vietnam eSIM guide is a good backup when cafe Wi-Fi fails. If you want it active on arrival, get an eSIM for Vietnam before you fly.
Power cuts and surge protection
Scheduled load-shedding hit parts of northern Vietnam during the 2023 heatwave, and brief outages can still happen in summer or after typhoons. Cities generally have reliable supply. A small surge-protecting adapter is cheap insurance for laptops, and a charged power bank covers short outages. Never charge a phone or laptop through a damp socket, a hazard in humid beach towns during the rainy season.
Where to buy an adapter in Vietnam
If you forget one, universal adapters and extension strips cost roughly 30,000 to 100,000 VND at electronics and phone shops in any city. Large chains such as The Gioi Di Dong and Dien May Xanh stock them, along with phone cables and power banks. Prices are as of 2026 and vary by shop. Bring a few dollarsβ worth of change, since small shops may not accept cards.
Packing checklist
- One universal adapter with USB ports.
- Dual-voltage chargers for phone, camera and laptop.
- A compact extension strip for hotel rooms and dorms.
- A 10,000 mAh or larger power bank (carry it in hand luggage, not checked).
- A short USB-C or Lightning cable, plus a long spare.
