Will your plug work
when you get there?
Check the adapter and electrical supply for your trip. Start with your home country, your destination and the Input label on your charger or device.
Plug adapter & voltage checker
A plug adapter and a voltage converter do different jobs.
An adapter changes the plug shape.
It does not change voltage or frequency. Choose one that fits the actual socket, preserves any required earth connection and is rated for your device.
The device label decides the voltage.
A device marked 100–240 V can accept those voltages. A single-voltage appliance may not. For a mismatch, use a suitable local appliance or ask the manufacturer about an appropriately rated converter.
Check the actual socket and local supply before plugging in. Country figures are nominal and buildings can differ. Take particular care with hair dryers, straighteners, kettles and other high-power appliances; a travel adapter is not a voltage converter.
