No, it's no joke. I just experienced a severe power surge that ruined some of my equipment so I bought a UPS to help guard against it happening again. For physical reasons I had to locate the device about six feet from my desktop. The manual that came with the UPS said not to use it with an extension cord. i assume that's because there is a factor that an extension cord adds to the efficiency/non-efficiency of the device. I want to plug my desktop directly into the UPS but the power cord is not long enough. I know a number of devices come with cords of varying lengths, apparently so extension cords do not need to be used. I was wondering if Apple also manufactured longer cords so I didn't have to use an extension cord.
I may not be that bright but I'm not given to posing humorous questions on a serious web site.
