“My laptop brick said 100–240V, so I focused on the wall cable and whether it would fit United States’s A · B outlets.”

Will my laptop charger work on United States’s 120 V supply?
For United States, verify the exact laptop equipment instead of relying on a country-level assumption. A check-in in New York is a good time to separate two questions: whether the plug fits and whether the equipment accepts 120 V. The laptop’s AC adapter should show an INPUT range that includes 120 V and 60 Hz. A label such as 100–240V ~ 50/60Hz normally covers the listed supply.
A charger made only for 220–240 V is not automatically suited to 120 V. Wide-input laptop bricks are common, so checking the label is usually more useful than guessing from the computer brand. Across different accommodations in United States, a tested laptop power setup is easier to repeat.

United States power: A · B · 120 V · 60 Hz
See the United States power plug guide →Will my laptop plug fit United States outlets?
The A · B outlet family answers plug fit for a laptop, not whether it accepts 120 V. United States lists A · B. If the laptop charger’s wall plug does not match, use a plug adapter or a compatible detachable AC lead; neither option changes voltage. In New York, a compact plug solution also keeps a heavy power brick from hanging awkwardly from the wall.

A hotel-room workaround in United States should not replace checking USB-C PD wattage and port sharing before departure. USB-C changes the packing decision but not the electrical rules. A USB-C charger may accept 120 V and still be underpowered for the laptop. Before replacing the original brick for a United States trip, compare USB-C PD wattage, port capability and whether the laptop expects a specific charging profile.
Grounding and detachable laptop cables in United States
Testing the complete laptop setup before United States keeps the travel-power kit simpler. Grounding deserves a separate look when the original laptop adapter uses a grounded cord. A · B describes the local socket family, but hotel and older-building outlet arrangements can vary. If your power brick uses a detachable cable, a country-compatible grounded lead can be cleaner than stacking adapters.

Anker 735 Charger — a compact USB-C option for a United States laptop kit
For a United States laptop setup, this is useful only when its INPUT covers 120 V and its USB-C output meets the computer’s charging requirement; check both before relying on it in New York.

Once a converter-free work setup is confirmed for United States, extra conversion hardware is easier to avoid. For Detroit, the simplest workflow is usually: verify the charger input, solve plug fit, then test the full laptop setup before departure. A voltage converter is normally unnecessary when the laptop adapter already accepts 120 V; adding one creates more bulk without improving a compatible switching power supply.
