Countries Where a Typical US Hair Dryer Is Unsafe

In the current PlugVoltage dataset, 34 of 40 tracked destinations produce a hard do-not-use verdict for a typical 120V-only high-watt US hair dryer.

Key finding. A plug adapter is not enough in high-voltage countries. For a typical 120V-only US hair dryer, the safer answer is a dual-voltage travel model, a local appliance, or leaving it at home.

Download the CSV export or cite this report with the visible assumptions above. The result is generated from the deterministic PlugVoltage engine and the country records in the public dataset.

This is device-safety guidance for a typical single-voltage high-watt appliance, not human electrical-safety advice. If your hair dryer label says 100-240V, check that exact label instead of using this generic report.
