700m power adapter for 240V, airplane, and car

Your 700m power supply is designed for multiple voltages and will switch automatically (you can check with the label on the power supply; it will say 100-240V, etc.) - all you need is the right adapter for the wall socket of the country you are visiting.

 

For use on the plane and in the car, there are converters available so check with your local computer shops.  Dell sells one too.
