Mine stays on all the time unless I am at a motel for the night.
The original model is easily removed IF you are not anal about cable management. It has a 8' power cord and a 8' Ethernet cord. Both of those have to be connected with a 6' power cable and a Ethernet cable (comes with a 20' Ethernet cable). Both have easily disconnected plugs, just have to keep those accessible.
Have not seen the Ultrex model, but if the cable connections are the same, the only difference is the quick disconnect clamp with the original one and three bolts to loosen with the Ultrex version.
I have two 360 power cables on my boat, one for when I use the outboard and the other when I fish electric-only waters. I use two different batteries depending on the waters I fish.
I also use either a 20' Ethernet cable or 2' Ethernet cable depending on if I want to share data between displays.
