Power sockets in Vietnam: plug types, voltage and whether you need an adapter
Vietnam runs on 220–230 V, 50 Hz. Sockets are mostly hybrids that take type A and type C plugs. Travellers from the UK, US or Australia will usually need an adapter; European two-pin plugs usually fit.
Vietnam runs on 220–230 V at 50 Hz. Sockets are mostly hybrids that accept both flat two-pin plugs (type A) and round European plugs (type C). Slim European two-pin plugs usually fit; travellers with UK (type G), Australian (type I) or three-pin US plugs will need an adapter. Most phone and laptop chargers are rated 100–240 V and work without a converter.

What voltage does Vietnam use?
Vietnam uses 220–230 V at 50 Hz — sources quote 220 or 230 V, which makes no practical difference. If you're from a 110–120 V country, check your devices: chargers labelled "100–240 V" work anywhere; anything else needs a voltage converter, not just a plug adapter.
Which plugs fit Vietnamese sockets?
Most Vietnamese sockets are hybrids for flat type A and round type C plugs. European two-pin plugs usually fit; grounded plugs with thick pins (type F) don't fit everywhere, and hotels have a mix of socket types. UK, Australian and three-pin US plugs need an adapter, so pack a universal one.
What standard are sockets in Vietnam?
Household sockets and plugs in Vietnam follow the national standard TCVN 6188, which mirrors the international IEC 60884 and is rated up to 16 A and 250 V. In practice you'll mostly see the hybrid A/C socket in homes, hotels and cafés. See also internet in Vietnam and first days in Nha Trang.
