Vietnam is a mix that catches Americans out. Its sockets commonly accept the flat US Type A pins and the European round Type C and F, so many plugs physically fit. The trap is voltage: Vietnam runs on 220 V, nearly double the US 120 V, so an American device that slots in can still be damaged. Europeans, by contrast, plug in with matching voltage.
| Coming from | Plug adapter | Voltage |
|---|---|---|
| From the United States | Not needed | Check converter |
| From the UK | Adapter needed | Compatible |
| From continental Europe | Not needed | Compatible |
| From Australia / New Zealand | Adapter needed | Compatible |
Plug adapters change the shape only. A "Check converter" flag means the voltage differs from your home country - fine for dual-voltage gear (phones, laptops, cameras marked 100-240 V) but risky for single-voltage appliances like hair dryers and travel kettles.

For dual-voltage devices yes; for single-voltage US appliances no, because Vietnam's 220 V can damage them.
Commonly Types A, C and F, at 220 V / 50 Hz.
Often not - the Type C Europlug fits and the voltage matches.
