Before you pack
Check a device plug and power label for your destination
Compare a device's plug type, input voltage range and frequency with a sourced country reference. Learn when a plug adapter differs from a voltage converter.
Choose the countries where the device plug comes from and where you will use it. Then enter the voltage and frequency printed on the device or its power supply. This checker uses a limited country reference list and flags what you should verify; it cannot certify a device or socket.
Do not guess missing label values. A travel plug adapter changes the plug shape; it does not change voltage or frequency. A voltage converter or transformer is a separate product and may be unsuitable for some devices. Check the appliance, adapter/converter ratings, grounding and manufacturer instructions before use.
How to read the result
The voltage check compares the destination's listed nominal supply value with the input range you entered from the device label. The frequency check flags a difference for manufacturer review; this page cannot determine whether a motor, clock or other device tolerates it. The plug-type check compares type labels only. It does not model partial compatibility, grounding, socket condition, regional variation, accommodation wiring or adapter quality.
Countries can have multiple socket types or local variations. Check your accommodation and the exact product label, and never force a plug. If voltage or frequency compatibility is uncertain, ask the device manufacturer or a qualified electrician.
Sources, reference dates and limits
- World Standards: Plug, socket & voltage by country (country reference table; page last updated 7 Sep 2025; checked 3 Nov 2026). This is a secondary reference and notes regional/multiple socket variation.
- Electrical Safety First: Using electricals overseas (check supply voltage, frequency and socket type; dual-voltage label example; checked 3 Nov 2026).
- Electrical Safety First: Travel adaptors (adaptors do not convert voltage or frequency; power rating and grounding cautions; checked 3 Nov 2026).
Country values shown in the selector are a screening reference, not a guarantee for every building or outlet. The checker works locally in your browser and does not send the countries or device details anywhere.
For costs for different countries on one trip, use the trip budget planner and currency worksheet. If your itinerary includes a connection, compare scheduled times with the connection-time planner.
How it works
Choose the device plug's country and your destination, select the plug type printed or shown for the device, and enter its voltage and frequency label. Verify the actual outlet and manufacturer requirements before connecting it.
Good to know
Does a travel plug adapter convert voltage or frequency?
No. Electrical Safety First says a travel adapter changes the plug connection but does not convert voltage or frequency. Check the device input label against the destination supply and use only equipment approved for the device's power and grounding needs.
What if the device label voltage range does not include the destination reference?
Do not rely on a plug adapter. Ask the device manufacturer whether a correctly rated voltage converter or transformer is suitable; some devices are not suitable for converters.
Does a matching plug type guarantee that the device is safe to use?
No. Type labels do not establish physical fit, grounding, outlet condition, power rating or local variation. Confirm the exact device and socket, and do not force a plug.
Are the country reference values universal for every building?
No. The list is a limited planning reference. Countries can have multiple socket types and regional variation; check your accommodation and the device manufacturer's instructions.
