Plug shape, voltage, frequency — the four things that decide whether your gear works on this route.
The story behind the route.
Why this specific origin → destination pair has the quirks it does — local context the data alone won't show.
Traveling from United Kingdom to United States of America means crossing more than just time zones. You're entering a completely different electrical ecosystem. The plug situation is straightforward: United Kingdom's Type G and United States of America's Type A/B don't work together. Voltage is where you need to pay attention. 230V in United Kingdom versus 120V in United States of America means you'll need more than just an adapter. Currency: USD – US Dollar. This isn't a route where you want to figure things out at the hotel.

- →Tap water is safe to drink in most areas
- →Check if your hotel has universal outlets in rooms (increasingly common in newer properties)
- →USB ports are everywhere in US hotels. Consider using those for phones/tablets.
- →Hair dryers and curling irons are the most common casualties of voltage mismatches. Check device labels.
What to pack for this route.
One adapter for the plug shape, one converter when voltage bands cross. That covers most of what you need.
A universal adapter covers this route plus 150+ other countries.
Bands differ (230V vs 120V). Hair dryers, curling irons, kettles need a converter — or a dual-voltage replacement.
