Power plugs & voltage in the United States
Do you need an adapter?
Coming from a Type A/B country (e.g. the US)? No adapter needed for the plug shape — the United States shares Type A with home.
Voltage here is compatible with a typical home supply — no converter needed, just the plug shape adapter if applicable.
A universal travel adapter covers the United States's plug type(s) plus most others, so you don't need a different one for every trip.

What plug type is used in the United States?
Type A, B, NEMA 14-30, NEMA 14-50 (Type A is the most common; the others are less common or largely historical).
Do I need a voltage converter for the United States?
No — the voltage is compatible with a typical 120V home supply.
Is a universal adapter enough?
Yes, for shape compatibility — a universal adapter covers the United States's plug type(s). It does not change voltage, so still check whether your specific device needs a converter (see above).
