Can I Fly With This?

What plug + voltage at your destination?

Pick where you're going. We'll tell you the plug type, voltage and frequency — plus any compatibility traps (Japan is 100 V, Brazil varies city-by-city, US appliances burn out on 230 V hairdryers).

Why 'dual voltage' isn't always enough

Plug type, voltage and frequency vary by country, and even devices labelled 100–240 V dual-voltage can fail in surprising places: Japan's 100 V can brown out hair dryers built for the US 120 V, and Brazil has cities on 127 V and others on 220 V depending on the state. Frequency (50 vs 60 Hz) is mostly irrelevant for modern electronics but matters for older motorised appliances (some old clocks, certain shavers). The plug shape is the easy part — adaptors are cheap — but voltage incompatibility can fry expensive gear permanently. Pick your destination to see plug type, voltage, frequency, and the compatibility traps that matter.

⚠️ Some countries (Brazil, Saudi Arabia, the Maldives) use different voltages in different regions or hotels. The summary here covers the most common case; always check the actual outlet voltage in your hotel room before plugging in a non-dual-voltage appliance.
