From Montenegro to Vietnam
When travelling from Montenegro to Vietnam: Some of your Montenegro plug types fit in Vietnam (C). Bring a compact adapter for the others. Voltage matches at 230V, so a basic plug adapter is enough for most devices. Frequency is the same at 50Hz.

About electricity in Vietnam
Vietnam runs on 230V/50Hz with Type A, B, and C sockets. Most outlets accept either US flat pins or European round pins, so many travellers will not need an adapter at all.
Grid & history
Hydropower provides about a third of Vietnam’s electricity, while coal and gas cover most of the rest. Solar has grown fast since the 2018 feed-in tariff.
Availability
Supply is reliable in cities and tourist areas. The mountainous north and the central highlands can see outages during typhoon season.
Sockets & hotels
Hybrid sockets that accept Type A flat pins and Type C round pins are common, while grounded Type B is less common in older buildings.
Energy mix
Hydro is the largest single source; solar is catching up.
Practical tips
- Most US, European, and Japanese plugs fit Vietnamese sockets directly.
- A small universal A/C adapter covers any odd outlet.
- Voltage is 230V, so US-only hair dryers may overheat.
