Just redecorated and refurbished my bedroom come man cave and now I am coming to the detail. hiding or a least tidying up the many cables I have for my TV, PVR, Sound bar and Chromecast and the only one causing me difficulty is the Chromecast power lead, which is a couple of feet short to conceal it with the aforementioned other electronics. I could run an extension from the extension but that defeats the object of having the original extension hidden away now. I do not no if an extension exists for the Chromecast power supply but I doubt it. Or perhaps a PSU with a longer cable? Any suggestions?
