“In New York, the phone was the easy part; I verified the USB-C wall charger accepted 120 V and then dealt with United States’s A · B socket.”

Will my iPhone wall charger work in United States?
For United States, verify the exact iphone equipment instead of relying on a country-level assumption. For an iPhone, start with the wall charger. United States is listed at 120 V / 60 Hz. A USB-C or older USB power adapter marked 100–240V ~ 50/60Hz generally includes that range.
Travelers from 220–240 V regions should not assume a single-voltage charger will accept 120 V; the charger label settles that question before plug shape. Across different accommodations in United States, a tested iphone power setup is easier to repeat.
United States power: A · B · 120 V · 60 Hz
See the United States power plug guide →Which phone plugs need an adapter in United States?
The A · B outlet family answers plug fit for a iphone, not whether it accepts 120 V. United States uses A · B. A North American flat-pin phone charger may fit directly in some A/B destinations, while European, British or Australian plugs often need an adapter there. In New York, the important part is matching the plug on the actual charger—not the connector that goes into the iPhone.

A hotel-room workaround in United States should not replace checking fast-charge cable and protocol before departure. Fast charging depends on the phone, charger and cable working together. For a United States trip, a compact USB-C Power Delivery charger can reduce the number of bricks in the bag, but only if its INPUT includes 120 V and the cable supports the charging setup you expect.
Using a power bank while traveling in United States
Testing the complete iphone setup before United States keeps the travel-power kit simpler. A power bank is useful between New York and Detroit, but it solves a different problem from wall compatibility. Keep the power bank for transit and the voltage-compatible wall charger for overnight charging; check airline battery rules before flying.
EPICKA Universal Travel Adapter — when the iPhone charger plug does not fit United States
Use it for plug shape only after confirming the wall charger accepts 120 V.

Once avoiding unnecessary conversion is confirmed for United States, extra conversion hardware is easier to avoid. There is usually no reason to add a voltage converter to a modern wide-input phone charger. If the charger label already includes 120 V, focus on A · B plug fit and cable condition. If the label is unclear or damaged, replace the charger rather than guessing.
