DC to DC converter for small electronics

Hey Matt, So I take it you're trying to eliminate a 120 volt wall cord and go straight into the 12 volt connector using the 12 volt system of the house which will be 14.4 or 14.6 at times. 13.7 or 13.2 at others. and 12.8, 12.6 and going lower as the evening progresses until the engine or generator start charging. Sounds like the Victron may be the solution you're looking for. Since this NAS is going to be rattling around in the truck camper, are you going to be using SSD drives? Will your NAS accept smaller 2.5 drives? I have a couple LACIE 4T USB drives RAID capable if desired. It's a much simpler solution than a hardwired NAS unit in the TC and easier to take with you if needed. Probably not as capable though as a true NAS designed to serve several work stations but will easily work for one person/computer. I saw the RV GEEKS on YouTube the other night, released a video on their electronic communication and NAS system. They had a NAS with I recall 6 full sized bays but I don't recall if they plugged into 120 volt or adapted to use 12 volt. They have a huge LION battery system so I suspect they used 120 volt and let the unit make it's own clean power. Hope it works out whatever you end up with.
