To be honest, I use solenoids on all of my installs. You can run high amperage through them with the turn of a key. Since all of the vehicles we build, do not have a Kussmaul Shoreline charging system, we need the entire console to shut down with the vehicle off. There is not a need to have the vehicle off and console powered up. I always use an 80amp continuous solenoid which is more than enough for a fully populated console.Our laptops are powered by a cigar plug so for the constant power needed, it has never drained the battery, but then again, all of our vehicles run throughout the day and never sit longer than 6-8hrs.
