Can I Use My Power Bank in United States?
You're good — plug right in.
Your device's voltage range matches this country, and the plug fits. You can use it directly — no adapter or converter needed. As a final check, confirm the voltage range printed on the device label.
The short answer
A power bank's wall charger is dual-voltage (100–240V) — a plug adapter is all you need. Note airline rules: power banks fly in carry-on only, usually under 100Wh (~27,000mAh).
United States runs 120V at 60Hz. 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.
