Vietnam uses plug types A, C and F at 220 V, 50 Hz. Which US plugs fit, when you need an adapter and why the voltage matters more.
The short answer
Vietnam uses plug types A, B, C, F at 220 V, 50 Hz. US plugs fit, so most US travelers need no adapter.
Vietnam uses a mix of flat-pin (type A) and round-pin (types C and F) sockets at 220 V. Many sockets accept both, so two-prong US plugs fit in most hotels.
Two flat parallel pins, no ground.
Where else type A is usedTwo flat parallel pins plus a round ground pin.
Where else type B is usedTwo round pins, no ground (the Europlug).
Where else type C is usedTwo round pins with ground clips on the sides (Schuko).
Where else type F is used"Converter" applies only to single-voltage devices. Chargers marked 100-240V need an adapter at most.
| Traveling from | Adapter | Voltage converter |
|---|---|---|
| United States or Canada | Not needed | For 120 V-only devices |
| United Kingdom or Ireland | Type C | Not needed |
| Mainland Europe | Not needed | Not needed |
| Australia or New Zealand | Type C | Not needed |
| Japan | Not needed | For 100 V-only devices |
Two-prong US plugs fit most sockets. This adapter covers three-prong plugs and sockets that don't take flat US pins.
Budget Europe adapter with 2 USB ports for Type C outlets
A universal adapter covers types A, C, G and I. It won't fit Switzerland, India or South Africa well.
Works in 150+ countries with 5 USB ports
Often not for two-prong US plugs, but pack a type C adapter for round-pin sockets and three-prong plugs.
220 V at 50 Hz. Devices labelled 100-240V work; 120 V-only devices need a converter.

Taro spent a decade in the music industry as a tour manager, crisscrossing the globe with artists and crews who demanded gear that actually worked. From overnight buses in the American Midwest to bullet trains in Japan, backstage in London to festival grounds across Europe—he's lived out of bags, cases, and carry-ons for years. That experience taught him what separates travel gear that survives the road from stuff that falls apart after one trip. Now he channels that hard-won knowledge into TravelGiftList, helping travelers find products that meet real-world demands.
