Don't see a problem re technical. However if the portable device shuts down at the pedestal, no current to the hard wire device. If pedestal glitch cooks the portable device and you go directly from the pedestal to the hard wire device, it will likely fail as well. Redundant systems are nice to have but you have to pay for them. For me, too many other potential issue headaches to deal with and our Progressive has been reliable for many years..
