How to check your hairdryer
Look for the "Input" rating on the plug, power brick or the handle near the cable:
- 100–240V ~ 50/60Hz – works anywhere in the world with a plug adapter.
- A switch marked 120/230 or 110/220 – dual-voltage: set it to match the country before plugging in.
- 220–240V only – fine in the UK and Europe, but not on the USA's 120V supply.
Plugs in the USA
Yes. You'll need a US-style (type A/B) adapter.
- Type A: Two flat parallel pins (no earth)
- Type B: Two flat parallel pins plus a round earth pin

Common questions
Can I use my UK hairdryer in the USA?
Most UK hairdryers are made for 220–240V only. On the 120V supply in the USA they run weak and slow, and converters strong enough for heated appliances are bulky. A dual-voltage travel hairdryer, or the hotel's, is the easy option.
What voltage is the USA?
120V at 60Hz. The UK is 230V at 50Hz.
Do I need a voltage converter for my hairdryer?
Only if it's 220–240V only. A dual-voltage model is a simpler and safer choice than a converter.
