→ Check Your Adapter NowThis is one of those questions that sounds simple but has a surprising number of wrong answers on the internet. The answer depends on three things: where you are from, where you are going, and what you are trying to plug in.
This guide gives you a straightforward, destination-by-destination answer — no filler, no guesswork — along with the one thing most articles miss: the difference between needing an adapter and needing a converter.
Adapter vs. Converter: Get This Right First
Most travellers confuse these two, and it can damage your devices if you get it wrong.
- A travel adapter changes the shape of your plug so it fits the socket. It does not change the electricity. If your device can handle the local voltage, an adapter is all you need.
- A voltage converter changes the actual voltage — from 110V to 220V, or vice versa. You only need this if your device is not dual-voltage.
How to check if your device is dual-voltage
Turn your device over or look at the power brick. Find the small text listing electrical specs. If it says something like "100–240V ~ 50–60Hz", it is dual-voltage and works anywhere in the world with just an adapter. This is the case for virtually all phones, laptops, tablets, camera chargers, and most modern travel hair tools.
If it only says "110V" or "120V", it is single-voltage and needs a converter in countries that run on 220–240V (most of the world).
By Destination: Do You Need an Adapter?
Results below are based on your home country's standard plug type. Use the table at the end if your country isn't listed here.
🇬🇧 United Kingdom
The UK uses Type G plugs — three large rectangular pins in a triangular arrangement, at 230V. This plug type is used almost nowhere else in the world (Ireland and Hong Kong are the main exceptions). If you are arriving from the US, Canada, Europe, Australia, Asia, or the Middle East, you need a Type G adapter.
| Coming From | Need Adapter? | Plug Type to Get |
|---|---|---|
| USA / Canada | Yes | Type G |
| Europe (Schuko) | Yes | Type G |
| Australia | Yes | Type G |
| India | Yes | Type G |
| Ireland / Hong Kong | No | — |
🇪🇺 Europe (Continental)
Most of continental Europe uses Type C or Type F plugs — two round pins — at 220–230V. Type C (ungrounded) fits most sockets; Type F (Schuko, with grounding clips) is used in Germany, Austria, Netherlands and others. Most sockets accept both. If you are from the UK, USA, or Australia, you need an adapter.
| Coming From | Need Adapter? | Plug Type to Get |
|---|---|---|
| USA / Canada | Yes | Type C or F |
| UK | Yes | Type C or F |
| Australia | Yes | Type C or F |
| Within Continental Europe | No | — |
| Italy (Type L) | Sometimes | Type C fits most Italian sockets |
🇯🇵 Japan
Japan uses Type A plugs — two flat vertical pins — at 100V. This is the same plug shape as the US and Canada. However, Japan's voltage is 100V, the lowest in the world. Most dual-voltage devices handle this fine (100–240V). The issue is single-voltage devices rated for exactly 120V — these may work poorly or not at all. Check your device label.
| Coming From | Need Adapter? | Voltage Note |
|---|---|---|
| USA / Canada | No adapter | Check device for 100V compatibility |
| UK / Europe | Yes — Type A | Dual-voltage devices fine |
| Australia | Yes — Type A | Dual-voltage devices fine |
| India / Middle East | Yes — Type A | Dual-voltage devices fine |
🇹🇭 Thailand
Thailand is one of the more adapter-friendly countries because its sockets accept Type A (flat two-pin), Type B (flat two-pin + ground), and Type C (round two-pin) — at 220V. This means travellers from the US, Canada, Europe, and much of Asia often don't need an adapter. UK plugs (Type G) will not fit, however.
| Coming From | Need Adapter? |
|---|---|
| USA / Canada | Usually no — but check voltage (220V) |
| Europe (round pins) | Usually no |
| UK | Yes — Type A or C |
| Australia | Yes — Type A or C |
⚠️ US travellers: Thailand runs at 220V. Your US phone charger and laptop (dual-voltage) will work fine. A US hair dryer rated 120V only will not — bring a travel version or a converter.
🇦🇪 UAE (Dubai, Abu Dhabi)
The UAE uses Type G plugs — the same as the UK — at 220–240V. This surprises many travellers, especially Americans who might expect something more similar to nearby countries. If you are from the US, Europe, Australia, or most of Asia, you need a Type G adapter for the UAE.
| Coming From | Need Adapter? |
|---|---|
| USA / Canada | Yes — Type G |
| Europe | Yes — Type G |
| UK / Ireland | No |
| Australia | Yes — Type G |
| India | Usually no — India also uses Type D/G |
🇦🇺 Australia & New Zealand
Australia and New Zealand use Type I plugs — two or three flat angled pins — at 230V. This plug type is also used in China, Argentina, and a few other countries, but is otherwise uncommon. If you are from the US, UK, or Europe, you need a Type I adapter.
| Coming From | Need Adapter? |
|---|---|
| USA / Canada | Yes — Type I |
| UK | Yes — Type I |
| Europe | Yes — Type I |
| China | Usually no |
🇮🇳 India
India primarily uses Type D plugs (three large round pins in a triangular pattern) and Type C, at 230V. Many modern sockets in Indian hotels also accept Type C round-pin European plugs. Travellers from the US or UK may find some sockets work and others don't — a universal adapter is the safest option.

For most travellers, a universal travel adapter covering Type A, C, G, and I is the practical choice. This covers the US, Europe, UK, Japan, Thailand, UAE, Australia, and most of the world with a single device.
What to look for
- USB-C port built in — so you can charge a phone or tablet without a separate charger
- USB-A port — for older devices and accessories
- Safety shutters — particularly important if you travel with children
- Compact form factor — some universal adapters are bulky and block adjacent sockets
- Not a voltage converter (unless you specifically need one) — converter adapters are heavier and more expensive
Devices That Almost Never Need a Converter
These device types are virtually always dual-voltage in 2026 and only need an adapter (never a converter):
- Smartphones and tablets (check: they say 100–240V on the charger)
- Laptops and MacBooks
- Camera battery chargers
- GoPro chargers
- Kindle and e-readers
- Most travel-specific hair dryers and straighteners (look for the "travel" label)
Devices That May Need a Converter
- Older or cheap hair dryers (check the voltage label — single-voltage appliances are common)
- Electric razors and beard trimmers (some older models are single-voltage)
- Medical devices like CPAP machines (some are dual-voltage, some aren't — always verify)
- Some kitchen appliances travellers bring for long-term stays
