Different countries use different electrical outlets. A travel adapter lets you plug your devices into foreign sockets. This guide covers plug types, voltage, and what to look for in an adapter.
Adapter vs Converter
Travel adapter: Changes the plug shape so it fits the socket. Does NOT convert voltage.
Voltage converter: Changes the electrical voltage. Rarely needed for modern electronics.
Most phone chargers, laptops, and camera chargers are “dual voltage” (100-240V) and only need an adapter, not a converter. Check the label on your charger – if it says “100-240V” you’re fine with just an adapter.
Common Plug Types
Type A/B (Americas, Japan): Two flat pins (A) or two flat plus ground pin (B). 120V.
Type C (Europlug): Two round pins. Used across Europe (except UK), South America, and Asia. 220-240V.
Type G (UK): Three rectangular pins. Used in UK, Ireland, Malaysia, Singapore. 230V.
Type I (Australia): Two angled flat pins plus ground. Used in Australia, New Zealand, China. 230V.
Plug Types by Country
| Country | Plug Type | Voltage |
|---|---|---|
| USA/Canada | A, B | 120V |
| UK/Ireland | G | 230V |
| Most of Europe | C, F | 230V |
| France/Belgium | C, E | 230V |
| Australia/NZ | I | 230V |
| Japan | A, B | 100V |
| China | A, C, I | 220V |
| India | C, D, M | 230V |
| Thailand | A, B, C | 220V |
| Brazil | C, N | 127/220V |
| South Africa | C, M, N | 230V |
Some countries use multiple plug types. Hotels sometimes have “universal” outlets that accept several types.
What to Look For
USB ports: Adapters with USB-A and USB-C ports let you charge phones and tablets directly without needing your charger’s plug.
Multiple outlets: Some adapters have both a socket for your plug and USB ports.
Universal adapters: Work in multiple regions. Good for frequent travellers but bulkier than single-region adapters.
Surge protection: Protects devices from power spikes.
Compact size: Easier to pack.
Safety
- Don’t overload adapters with high-power appliances (hair dryers, kettles)
- Check your device’s voltage compatibility before plugging in
- Look for adapters with safety certifications (CE, FCC)
- Don’t use damaged adapters

Frequently Asked Questions
What is the difference between a travel adapter and a voltage converter?
A travel adapter only changes the plug shape to fit foreign sockets. A voltage converter changes the electrical voltage. Most modern electronics are dual-voltage (100-240V) and only need an adapter, not a converter.
Do I need a voltage converter for international travel?
Probably not. Check the label on your charger – if it says “100-240V” you only need a travel adapter. Voltage converters are typically only needed for older electronics or single-voltage hair appliances marked “120V only.”
What plug type do I need for Europe?
Most of Europe uses Type C (two round pins) and Type F (two round pins with grounding clips). Exceptions include UK/Ireland (Type G), Switzerland (Type J), and Italy (Type L which also accepts Type C).
Will my US electronics work in Europe?
US electronics rated for 100-240V (most phones, laptops, cameras) work fine with just a plug adapter. Single-voltage devices rated only for 120V need a voltage converter or you should use dual-voltage alternatives.
What is a universal travel adapter?
A universal travel adapter has multiple plug configurations that work in different regions (EU, UK, US, Australia). They’re ideal for frequent travelers visiting multiple countries but are bulkier than single-region adapters.
Should I buy a travel adapter with USB ports?
Yes, adapters with USB-A and USB-C ports are very convenient. They let you charge phones and tablets directly without needing your charger’s plug, and many can charge multiple devices simultaneously.
