The USA uses Type A and B sockets at 120V. Here's which adapter you need, and which UK devices won't work without a converter.
You need a US adapter (Type A or B, with flat pins). The USA uses 120V, so check each device's label: most phone and laptop chargers are fine, but many UK hair dryers and straighteners aren't.
Type A and Type B
120V, 60Hz
The USA uses Type A and Type B sockets, with two flat parallel pins (Type B adds a round earth pin). Your adapter needs flat US-style pins.
Possibly. The USA runs on 120V at 60Hz, roughly half the UK's voltage. An adapter changes the plug shape, not the voltage.
Check the label on each charger or appliance. If it says 100–240V, it will work in the USA with just an adapter. Most phone, tablet, camera and laptop chargers are like this.
If it only says 230V or 220–240V, it isn't designed for US voltage. This is common with UK hair dryers, straighteners and curling tongs. Rather than buying a heavy converter, most people use the hotel hair dryer or buy a dual-voltage styling tool.
MyTravelPal Pro Universal Travel Adaptor
Covers the USA as well as Europe, with USB ports so you can charge several devices from one socket. It adapts the plug, not the voltage.
Charge through USB where possible. USB charging works the same everywhere, so it avoids any voltage worries.
Take a power bank for theme park days. Tickets, ride reservations and payments often depend on your phone.
INIU 10,000mAh 45W Power Bank
Compact, fast USB-C charging and enough capacity for a full day out without becoming a brick in your bag.
Only if the label says they're dual voltage (100–240V). Otherwise they won't work properly and could be damaged.
Almost certainly. Check for 100–240V on the plug. Most modern phone chargers are dual voltage.
Yes. Every US state uses the same Type A and B sockets.
