Travel Power Compatibility Checker
Select a device, destination, and label voltage; the checker separates plug fit, voltage mismatch, and high-watt risk.
Examples this checker handles
| Scenario | Input assumption | Destination data | Result |
|---|---|---|---|
| Hair Dryer in Italy | Typical US 120V-only dryer | 230V / 50Hz · Type L/F/C | Do not plug this in Frequency mismatch (device 60Hz vs grid 50Hz): motor speed or timing may change. Check the manufacturer instructions. |
| MacBook Pro Charger (USB-C Power Adapter) in Japan | 100-240V charger brick | 100V / 50/60Hz · Type A/B | Conditional compatibility Dual-voltage electronics are voltage-safe; plug fit still matters. |
| Curling Iron in Brazil | Label not confirmed | 127V / 60Hz · Type N/C | Check your device label first Brazil uses BOTH 127V and 220V depending on the city. Confirm the exact local voltage before plugging in. |
What the verdicts mean
| Verdict | What it means |
|---|---|
| Conditional compatibility | Confirm the actual label, frequency, plug and required grounding. |
| Plug adapter needed | Voltage support is conditional on your exact label; check the adapter's earth connection. |
| Voltage converter needed | Your device runs on one voltage that doesn't match your destination. |
| Adapter + voltage converter needed | The voltage doesn't match and the plug shape is different. |
| Do not plug this in | Do not connect this device to incompatible voltage. A plug adapter cannot correct it. For high-power heating, PlugVoltage recommends a suitably rated local appliance or a manufacturer-approved travel model instead of travel conversion. |
| Check your device label first | One line on your device decides the answer. Here's where to find it. |
| Not enough information | Tell us your destination for an exact verdict. |
Why voltage matters more than the plug
A plug adapter only changes the shape of your plug. It does not change the voltage. A 120V-only device on a 230V outlet can overheat or catch fire — which is why we check your device's voltage, not just the socket.
