United States of America to United Kingdom
Traveling from United States of America to United Kingdom? You'll need an adapter, and a voltage converter for the 110V difference.
Need an Adapter?
Yes! Yes, you need a Type A/B to Type G adapter
Need a Voltage Converter?
Yes — 230V can damage single-voltage United States of America devices
🔍 Why This Route Matters
United States of America and United Kingdom couldn't be more different when it comes to power systems, and that matters for every device you pack. United States of America uses Type A/B plugs, while United Kingdom runs on Type G. They're completely incompatible. Where things get tricky: United States of America supplies 120V of power, but United Kingdom delivers 230V. That's enough difference to damage devices without proper conversion. National animal is the British Sign Language. A little preparation goes a long way on this route.
Side-by-Side Comparison ⚡
🎯 What Locals Know (That Tourists Don't)
- ✦Uses 12H time format (e.g., 11:00 PM)
- ✦Temperature measured in Celsius (°C)
- ✦Electrical system uses 230V at 50Hz with Type G plugs
- ✦Tap water safety: drinkable
- ✦Most United Kingdom hotels have a limited number of adapters at the front desk. Ask early.
- ✦Many UK outlets have individual on/off switches. Make sure yours is flipped on.
- ✦Older electric razors and heated styling tools often aren't dual-voltage. Leave them home or buy locally.
What You Need for This Trip 🧳
Plug Adapter
RequiredUnited States of America's Type A/B plugs won't fit United Kingdom's Type G outlets.
Voltage Converter
May Be RequiredUnited Kingdom uses 230V vs United States of America's 120V. Most modern electronics handle this automatically.
Airport & Arrival Tip
LHR is your first stop, and potentially your first charging opportunity. Restaurants and cafes inside the secure area usually have outlets at table seating. Some airports have vending machines with travel essentials including adapters. Worth checking before heading to stores. Taxi rides to the city center take 30-60 minutes. Not enough time for meaningful charging anyway. First day is best for sorting out power issues. You'll be less stressed and more alert.
Packing Advice
Pack both a plug adapter (Type A/B to Type G) AND a voltage converter (120V to 230V). You'll need both. All-in-one adapters with built-in USB charging are worth the investment for frequent travelers. Power banks must go in carry-on luggage (not checked bags). TSA and international rules are strict about this. Bring both USB-A and USB-C cables if you have devices that use different standards. Hair dryers are heavy and voltage-sensitive. Hotels in United Kingdom almost always provide them. Pack adapters in your carry-on. You might need to charge during layovers or if checked luggage is delayed.
Seasonal Considerations
United Kingdom's seasons affect more than just your wardrobe; they impact your device strategy too. **Summer travel:** Longer daylight hours mean more time exploring and less time in your hotel. Power banks essential. **Winter travel:** Cold weather kills battery life quickly. Keep devices close to your body to maintain charge. **Holiday season:** Peak travel times = longer airport waits = more charging opportunities if you're prepared. Whatever the season, arrive with everything fully charged. You can't predict your first day's access to power.
