We’ve all had that travel-power moment: You drop your bag at a hotel in New York, reach for the charger before doing anything else, and realize the outlet is not quite what you use at home. If you are traveling from the US or Canada, the outlet may look reassuringly familiar.
If you are coming from the US or Canada, the plug shape is already familiar. That makes the device’s own voltage rating the more useful thing to verify.
Good news — the label usually gives you the answer: check the INPUT range on the charger or appliance you are actually bringing. Many phone and laptop chargers accept 100–240V, which covers the 120 V supply in United States. Then you only need to decide whether your plug physically matches the A/B socket.
“My phone charger fit the A/B socket, so the only thing left to verify was the INPUT range.”

What do power plugs in United States look like?
If you’re searching “what plug does United States use” — the listed standards are Type A and Type B. Type A has two flat parallel pins; Type B has two flat parallel pins plus a round grounding pin. Socket availability can vary by building, so check your accommodation when the destination lists more than one standard.
United States power plugs: Type A and Type B
Do you need a travel adapter for United States?
Here’s the quick physical-fit check:
- From the US or Canada? Your Type A/B plug may fit physically.
- From continental Europe? Your round-pin plug usually needs an adapter for A/B.
- From the UK? A UK Type G plug needs an adapter for A/B.
- From Australia or New Zealand? A Type I plug needs an adapter for A/B.
- Not sure? Compare your plug with the listed A/B socket types. Then check voltage separately.
Buy a Travel Adapter for United States
Already know you need one? A country-specific adapter can be the lightest option for a single trip; a universal adapter can be more convenient for a multi-country itinerary. Hair dryers and other high-power appliances still need a separate voltage check.
For most travelers who need a plug-shape change, compare a universal travel adapter that includes A/B support.

Can I Use My iPhone, MacBook or Hair Dryer in United States?
The safe answer depends on the exact device, not just the country. Check both the INPUT voltage and the plug shape.
iPhone & USB-C chargers in United States
Many modern phone chargers accept 100–240 V, but confirm the INPUT label on your charger. If the voltage is supported, the remaining question is whether its plug fits A/B.
MacBook & laptop chargers in United States
Many laptop power adapters are wide-voltage, but verify the exact charger you own. Plug fit and voltage compatibility are separate checks.
Dyson Airwrap / Supersonic in United States
Dyson hair tools can be region-specific. Check the exact model, the voltage on its label, and the region where it was purchased before using it in United States.
Hair dryer, straightener & curling iron in United States
These appliances are less forgiving than phone chargers. If the label shows 220–240 V only, it is not a match for 120 V. Check wattage as well as voltage.
What Voltage and Frequency Are Used in United States?
United States is listed at 120 V and 60 Hz.
Compare that with the INPUT label on your charger or appliance. A label such as 100–240V usually covers a broad voltage range, but the plug shape still has to match.
High-power appliances deserve extra care because many are single-voltage.
Buy a Voltage Converter for United States — Only if you need it
Not every traveler needs a voltage converter. If your device already supports 120 V, you can usually focus on plug shape.
A converter is worth considering only when the device is not compatible with the local supply. Match the converter to both voltage and wattage requirements.
