Convert 120V to 12V

I Just got a macerator to empty tanks at home and am a bit stumped on powering it. I know I can pull right off the battery but am wanting to run it off my house/shore power. Reasons being I have two tank outlets on my 5th wheel so wiring up to both is a hassle. Also, I mainly bought this thing just to avoid lines at dump stations and so if I use my RV at home I can dump. I may wire up the RV at some point but for now I'm just looking for home use.

Why in the world are you making this so complicated when it's SO simple? :h You haven't told us just which macerator you have but assuming it's a 12 vdc powered FloJet Waste Macerator just connect it to your rig's battery, whether plugged into shore power or not. Since I use my own FloJet frequently for exactly the same purpose I wired switched 12 vdc using 12 gauge zip cord from the battery back to the waste gate location where I installed a standard Bargman connector. If you want to run the macerator in 2 different locations either install a Bargman at each location OR just one midway between the 2 locations and extend the macerator's cable so it will reach either. The FloJet has a 20 amp fuse in the handle switch so 12 gauge is fine - been using mine for years with no issues at all. This is too simple, no need to over complicate it. :R
