Travel Adapter: Complete Guide
What you need to know about travel adapters, plug types, and voltage when traveling abroad.
What is a travel adapter?
A travel adapter is a device that lets you connect your electronics to wall outlets that use a different power plug shape. Countries use different power plug types (Type A, B, C, F, G, etc.), so an adapter simply changes the physical connection—it does not change the voltage.
See our power plug types by country list to find which power plug type your destination uses.
When do you need one?
You need a travel adapter when the power plug type in your destination country differs from your home country. For example, travelers from the US (Type A/B) need an adapter in Europe (Type C/F) or the UK (Type G). See our power plug types by country for a full list.
You may also need a voltage converter if your device does not support the destination voltage (e.g. 110V vs 220V). Most modern laptops, phones, and cameras are dual voltage (100-240V) and only need a power plug adapter.
Adapter vs converter
- Adapter: Changes the plug shape. Required when the outlet has a different physical design.
- Converter: Changes the voltage. Required when your device does not support the destination voltage (e.g. 220V to 110V).
Most travelers only need a plug adapter for dual-voltage devices. Check your device label for "INPUT: 100-240V" to confirm.
Universal travel adapters
If you visit multiple countries, a universal travel adapter that includes several power plug configurations (e.g. Type A, B, C, F, G) can work in 150+ countries. Check which power plug types your destinations use on our power plug types by country page.
Where to buy
Travel adapters are sold at airports, electronics stores, online retailers (e.g. Amazon, Best Buy), and travel shops. For better selection and prices, buy before your trip.
Quick tips
Check your device
Look for "INPUT: 100-240V" on the power supply. If you see this, your device is dual voltage and only needs a plug adapter.
High-wattage appliances
Hair dryers and straighteners often are not dual voltage. Consider buying local versions or using hotel-provided appliances.
Frequently Asked Questions
Do I need a travel adapter?
It depends on your origin and destination. If the power plug types or voltage differ, you may need an adapter and sometimes a voltage converter. Use our travel compatibility tool to check.
What's the difference between an adapter and a converter?
An adapter changes the physical plug shape so your device fits the outlet. A converter changes the voltage (e.g. 220V to 110V). Most travelers only need an adapter for dual-voltage devices (100-240V).
What is a voltage converter?
A voltage converter transforms electrical voltage from one standard to another (e.g. 220V to 110V). You need one when your device does not support the destination voltage. Most laptops and phone chargers are dual voltage and only need a power plug adapter.
What is a power adapter?
A power adapter (or travel adapter) is a device that lets you plug your electronics into outlets with a different plug shape. It does not change voltage—it only adapts the physical connection.
Adapter or adaptor—which is correct?
Both are correct. "Adapter" is common in US English; "adaptor" is often used in UK English. They refer to the same device.
What adapter do I need for UK to US (or US to UK / EU to UK)?
UK uses Type G plugs; US uses Type A/B; most of Europe uses Type C/F. Use our travel compatibility tool: select your origin and destination to see if you need an adapter and which type.
Can I use a Type C power plug in a Type F socket?
Yes. Type C (Europlug) power plugs fit into Type F (Schuko) sockets used in Germany and much of Europe. You may need an adapter when traveling from a country that uses Type A/B (e.g. US) or Type G (UK) to Europe.
Type A vs Type B: what's the difference?
Both are used in North America and Japan. Type A has two flat pins; Type B adds a round grounding pin. Type B is safer for grounded devices. Many sockets accept both.
