Travel Adapter Guide
Different countries use different electrical outlets, and the plug on the end of your charger will not fit most of them. This guide covers what a travel adapter actually does, how to work out which one you need, and the handful of things that genuinely go wrong.
What is a travel adapter?
A travel adapter is a small plug-shaped device that changes the shape of your plug so it fits a foreign socket. It does not change the electricity coming out of the wall. You plug your existing charger into one side, and the other side carries pins that match the sockets at your destination.
That distinction is the one most people get wrong, and it is worth being precise about. An adapter changes the plug shape. A converter changes the voltage. They are different products solving different problems, and buying the wrong one is how devices get destroyed.
For almost everything you travel with, the adapter is all you need. Phones, laptops, tablets and camera chargers are built to run on any mains supply in the world.
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.
Which travel adapter do I need?
Four questions, in this order. They take about a minute and they settle it.
1. Where are you going? Find your destination in the table above and note the plug type. If you are visiting more than one country on the same trip, note all of them, because a single-region adapter will strand you halfway.
2. Does your kit run on 100-240V? Look at the small print on the charger brick itself, not the device. If it reads 100-240V, an adapter is all you need. If it reads 120V only or 230V only, that specific item needs a converter or it needs leaving at home.
3. Is anything earthed or high-powered? If a device has three pins at home, it wants an earth at the other end too. Two-pin adapters cannot provide one. This matters for hair dryers, travel irons and some laptop bricks, and not at all for a phone charger.
4. One trip or many? A single-region adapter is smaller, cheaper and usually better built. A universal adapter is bulkier and has more to go wrong, but it covers everything and you stop thinking about it. If you travel a few times a year to the same region, buy the single-region one.
If the answer to all four is straightforward, one adapter with USB-C will cover the whole trip.
What to Look For
USB-C wattage is the specification that matters, and the one nobody prints on the front of the box. Plenty of adapters advertise USB-C without saying what it delivers. A 5W or 12W port charges a phone slowly and will not meaningfully charge a laptop at all. A modern laptop wants 45W upwards, and many want 65W or more. If you intend to leave the laptop brick at home, check the adapter states USB-C Power Delivery at a wattage your laptop accepts. If it does not state a figure, assume it is low.
Check the current rating. Travel adapters are usually rated somewhere around 6A to 10A, and that ceiling is real. It is comfortably enough for chargers and comfortably not enough for anything that heats.
Earth passthrough. Many compact adapters have no earth path at all, even where the socket provides one. A Europlug-style two-pin adapter will physically fit a German or French socket and leave your device unearthed while doing so. For chargers this is fine. For anything with a metal body or a heating element it is not.
Fuses. A replaceable fuse is a good sign, both because it means the adapter is expected to protect something and because it means one surge does not bin the whole unit.
Beyond that: sockets and USB ports you can use simultaneously, a shell that does not sag out of a loose hotel socket, and a size you will actually pack.
Safety
The adapter is the least dangerous thing in this chain. The mistakes around it are what cause problems.
Do not run heat through one. Hair dryers, travel irons, kettles and straighteners pull far more current than a travel adapter is built for. Hotel hair dryers exist for this reason. If you must bring your own, bring one sold as dual voltage and check the adapter’s rating against it.
Fitting is not the same as earthing. A two-pin plug slots happily into an earthed European socket. The earth simply is not connected. If your device came with three pins, it was given three for a reason.
Voltage is the one that destroys things. Plugging a 120V-only device into a 230V supply will usually end it immediately, and occasionally dramatically. Going the other way, a 230V device on a 120V supply generally just underperforms. Check the brick.
Buy certified, and replace damaged units. Look for CE or UKCA marking. Cracked housings, bent pins and anything that runs hot or smells of warm plastic should go in the bin rather than the suitcase.
Unplug before you leave. Adapters sit loosely in foreign sockets and are the single most forgotten item in hotel rooms, usually still holding a charger.

Frequently Asked Questions
What is a travel adapter?
A travel adapter is a small device that changes the shape of your plug so it fits a socket in another country. It does not change the voltage. Your existing charger plugs into one side, and the other side has pins matching the sockets at your destination. For phones, laptops and cameras, an adapter is normally all you need.
What does a travel adapter actually do?
It reshapes the connection and nothing else. The electricity passing through is whatever the wall supplies, at whatever voltage the country runs. An adapter cannot make a 120V-only device safe on a 230V supply, and it cannot add an earth connection that its own pins do not carry.
Do I need a travel adapter?
If your destination uses a different socket type from home, yes. Check the plug type table above. The only common exceptions are travelling between countries that share a type, such as the UK and Ireland, or much of mainland Europe where Type C and F are interchangeable for two-pin plugs.
Is a travel adapter the same as a charger?
No. A charger converts mains power into the low voltage your device needs, and it is the brick on your cable. An adapter only lets that brick physically fit a foreign socket. Some travel adapters include USB ports, which means they can act as a charger too, but the two jobs are separate.
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.
