I've had no issues with my two launch TiVo Minis. The power cord is snug on both. So they must have changed suppliers or something later on to cause this issue. I can move my units around and the power cord will not accidentally come out. I would certainly be ticked off if it did though. I moved one around recently to make room for an XBOne. I moved it back and forth and the power cord was still connected. Although I did need to eventually disconnect it to move it to a different shelf. But the entire time moving it around and even having it hang vertically, it stayed powered up.
