Travel adapter from Vietnam to United States

✅

No Adapter Needed

You will not need a plug adapter — Vietnam and United States share at least one common plug shape (Type A, Type B). Voltages differ (230 V at home vs 120 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not. The mains frequency is also different (50 Hz vs 60 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
