The US uses different plug types and voltage than the UK. Here’s what UK travelers need to know.
Featured Product
Plug Types
| Region | Plug Type | Description |
|---|---|---|
| UK | Type G | Three rectangular pins |
| US | Type A | Two flat parallel pins |
| US | Type B | Two flat pins + grounding pin |
UK plugs don’t fit US outlets. You need a plug adapter.
Voltage Difference
- UK: 230V, 50Hz
- US: 120V, 60Hz
This is an important difference. The US uses lower voltage than the UK.
Dual-voltage devices (100-240V): Only need a plug adapter. Check the label on your charger – most phones, laptops, tablets, and camera chargers are dual-voltage.
Single-voltage devices (230V only): Need both a plug adapter AND a voltage converter. This includes many UK hair dryers, curling irons, and older electronics.
What You Need
| Device Type | What You Need |
|---|---|
| Phone/laptop charger | Plug adapter only |
| Electric razor | Usually plug adapter only (check label) |
| Hair dryer | Probably voltage converter + adapter |
| Curling iron | Probably voltage converter + adapter |
Buying Adapters
- Amazon (before travel)
- Electronics stores
- Airport shops
- Many US retailers (Walmart, Target, Best Buy)
Choosing an Adapter
Consider:
- Grounded or ungrounded: 3-pin UK plugs need grounded adapters
- USB ports: Useful for charging phones directly
- Multiple outlets: Handy if you have several devices
- Surge protection: Protects electronics from voltage spikes
Safety Tips
- Check device voltage before plugging in
- Don’t overload adapters with high-wattage devices
- Unplug when not in use
- Use surge protectors for expensive electronics
