For each team, please bring the flag corresponding to your country as well as a standard pole.
In order to be able to connect your electrical devices to the electrical outlets available at the airports, please bring your EU adapters and your extension cords.

Be sure your devices can support an alternative voltage of 220v/230v without any converter. 

A standard plug like the one in figure a) can be plugged in a French socket (type F). However, for outdoor uses like camping or to power some equipment on the airfield, be sure to have a proper plug adapter like b) (3-wire grounding plug) to ensure a ground connection.
