Cigarette lighter not working

[GHunter2]

Hi all

My cigarette lighter in my polo 2005 doesn't seem to be working. I change the fuse and it works for approx 5mins, the new fuse doesn't burn out but the cigarette lighter has no power to it

Does anyone know what could be wrong?

I use sat nav and compressor through it
Thanks

Anyone any ideas? Is there any way of removing the cigarette lighter?
