Help with understanding the Opus and ITPS

I know these are DC to DC power supplies. Do these have cables that run all the way to the battery, or do they hook into a cigarette lighter? That would be the best setup IMO, simple to do. Also, do they get any larger than 150w?

Opus needs to run to the battery.....I would strongly urge you NOT to run something off of your cig adapter and always run a pos and neg to your battery

More appropriately, run a fused lead wire from your positive battery terminal and bolt the other lead to a ground point near the power supply (any solid metal part of your car).
