Will this work with the Yun?

Today I was surfing the web and I wanted to use a 9 volt dc battery clip with a micro-USB plug adapter cable and use them together to power my Aruino Yun. The only question I have is, will the micro-USB plug adapter cable work with a 3.5 mm dc male plug (the size of the port the Arduino UNO uses)?

no - it needs to be a regulated 5v
