as the computer is not a great distance from the battery bank, I hate to turn dc to ac and then back to dc through the "brick". I am interested in the 12v/120v power pack as a solution as I am not running wires around a house. It's a cargo van. I have not found the unit you refer to. I do respect the concerns of others who would be more likely to route current for long distances. Can you give me references or keywords that will help me find the type of unit you mention? My searches keep bringing me inverters. Thank you for your feedback if you find time and for the feedback you have already provided!!!
