From Cuba to Vietnam
When travelling from Cuba to Vietnam: Good news: all your Cuba plug types fit in Vietnam. Voltage is different (120V → 230V). Check your charger label; if it doesn’t list 230V you’ll also need a voltage converter. Frequency differs (60Hz → 50Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.

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.
