Type A Type B · grounded

Standard 120V at 60Hz. Type A is ungrounded (two flat blades); Type B adds a round ground pin. A single-voltage 220–240V appliance brought from Europe or Asia will run at roughly a quarter power or fail to start here — but it will not burn out.

United States outlet FAQ

Can I charge my phone in United States without a converter?

A voltage converter is unnecessary only if your charger’s actual INPUT range covers the local supply and frequency, and its manufacturer permits this use. Confirm the exact outlet, plug fit and any required grounding. A typical charger profile does not verify your model.

Is 120⁠V dangerous for US devices?

United States runs 120V, close to the US 120V, but a shared voltage zone does not prove compatibility. The exact input range must include this voltage and the local frequency.

What plug type does United States use?

United States uses Type A/B sockets at 120⁠V / 60⁠Hz.
