About Socket Voltage & Plug Type Quick Reference
Country-level power basics
Each entry lists the country, nominal voltage, frequency, common plug types, and short notes from maintained IEC and world-plug reference sources. It is meant for pre-trip adapter planning, not live electrical inspection.
Search, filter, and share the current view
You can search by country or plug type, narrow the table by region and plug family, and share a link that preserves those query settings. This makes it easier to send the same adapter checklist to travel companions.
Still verify the device and location
Voltage tables cannot guarantee that every outlet, power strip, charger, or appliance is safe. Check your device label, accommodation guidance, airline restrictions, and local adapter quality before plugging in valuable electronics.
FAQ
Common questions and answers about this topic.
What voltage do different countries use?
Most countries use one of two systems - roughly 110-127V at 60Hz (for example North America, Japan, and Taiwan) or roughly 220-240V at 50Hz (most of Europe, Asia, Africa, and Australia). Check the table for the exact country.
Do I need a travel adapter or a voltage converter?
A plug adapter only changes the plug shape; a converter or transformer changes the voltage. If your device is dual-voltage (marked 100-240V), you usually need only a plug adapter. A single-voltage device used on a different system may also need a converter. Always check your device's rating label.
How do I know if my device is dual-voltage?
Look at the label or power brick. A range such as 100-240V ~ 50/60Hz means it works worldwide with just a plug adapter. A single value such as 120V only means it is not dual-voltage.
Does the 50Hz vs 60Hz frequency matter?
For most electronics and chargers, no. Frequency mainly affects devices with motors or mains-driven clocks, and some older appliances. Modern dual-voltage chargers handle both.
How many plug types are there?
There are over a dozen standardized plug types, labeled A through N. The table shows which types each country uses so you can match the right adapter.
What does this socket voltage guide cover?
It lists voltage, frequency, and plug type by country, filterable by region or plug type, so you can check what you need before you travel.
