See that there? That’s an outlet with an integrated extension cord that recoils into the wall if it’s not being used. If you need it, the extension cord comes out of the wall with a simple squeeze of the buttons on the side of the plug and then drags out up to 1.5 meters (almost 5 feet).

The socket here is called the Rambler Socket and it was designed by Meysam Movahedi.

I wish every plug had this feature. Soooooo useful!
