Clear answers about international power — instantly.
Every year, travelers fry laptops, ruin hair dryers, and blow fuses because of confusing or contradictory information about international electrical standards. VoltageChecker was built to fix that problem cleanly.
You tell us where you're going and what device you're bringing — we tell you exactly what you need: an adapter, a voltage converter, or nothing at all. No jargon. No guesswork. No buying the wrong thing at the airport.
⚡ Our philosophy: Electrical travel advice should be free, fast, accurate, and easy to understand for everyone — not locked behind a premium subscription or buried in technical manuals.
The tool is especially useful when traveling between regions with different voltage standards — such as North America (110–127V) and Europe, Asia, or Africa (220–240V) — where plugging in the wrong device without preparation can cause permanent damage or a safety hazard.
195+ countries. 16 plug types. Every major standard.
VoltageChecker covers every UN-recognized country plus key territories, providing detailed power compatibility information across six core data points:
Three steps to a clear compatibility verdict.
VoltageChecker is designed to get you a useful answer in under 30 seconds — no account, no technical knowledge required.
Pro tip: The most important thing to check is the voltage label on your actual device — not just the device type. Look for the input rating on the power brick or on the device itself. A label reading "Input: 100–240V ~ 50/60Hz" means your device is dual-voltage and only needs a plug adapter anywhere in the world.
How we maintain and verify our data.
International power standards change rarely — but they do change. Brazil's full transition to the NBR 14136 Type N standard, India's ongoing infrastructure modernization, and incremental IEC harmonization across European countries are all examples of real-world updates that affect our database.
We review and update our country data regularly, cross-referencing multiple authoritative sources to ensure accuracy. Our primary data sources include:
If you notice outdated or incorrect information, please contact us. We review all reports promptly and credit verified corrections to our database.
Independent. Unaffiliated. Built by travelers, for travelers.
VoltageChecker is an independent web project created and maintained by a small team of frequent travelers and web developers who got tired of the same problem: unreliable, outdated, or overly technical information about international power standards scattered across dozens of websites with conflicting advice.
We built the tool we wished existed — one that gives a clear, correct answer in seconds without requiring you to understand electrical engineering or navigate a forum thread from 2014.
⚡ No conflicts of interest: We are not affiliated with any electrical equipment manufacturer, travel gear retailer, or adapter brand. Our compatibility verdicts are based purely on objective electrical specifications, not commercial relationships.
All content on this site — including country data, plug type descriptions, and device guidance — is written and maintained in-house. We do not publish sponsored recommendations, paid placements, or affiliate-driven product reviews.
Please read before relying on this tool.
VoltageChecker provides electrical compatibility information for general travel guidance purposes. We work hard to keep all data current and accurate, but there are important limitations every user should understand.
Important: Electrical infrastructure can vary within countries — particularly in remote areas, older buildings, and rapidly developing regions. Some countries have ongoing transitions between voltage standards that may result in inconsistent outlets within the same city. Always verify the specific outlet voltage at your actual destination before plugging in valuable or irreplaceable equipment.
The following situations require extra caution beyond what this tool can address:
Older buildings in countries undergoing infrastructure modernization may still have legacy wiring or outlets that differ from the current national standard. In some regions — particularly parts of Africa, Southeast Asia, and South America — voltage can fluctuate significantly from the published specification, which may affect sensitive electronics even when nominal compatibility exists.
For high-value equipment, medical devices, or specialized professional electronics, always consult the device manufacturer's official international travel guidance and, where appropriate, a certified electrician in the destination country.
