Charging phones? I'm a fan of sticking with 12V and using a car charger. I installed a pair of 12V outlets inside a cabinet.
I've replaced old in line fuses with in line manual resetting breakers. They are cheap, and no more fuses to worry about. I went manual reset instead of automatic as I would rather know if something trips.
It sure looks like there is another fuse somewhere in your system. I don't know Scamps. On my Trillium
, there was a fuse in the front gaucho cabinet, and a second fuse on the power center. I replaced my old power center (good riddance) and swapped the gaucho in line fuse with a breaker as I mentioned. My new power center has a 40A DC fuse for the battery itself. If that goes and I am dry camping
, I am out of luck (need to get some spares). I also have a fuse (actually in line breaker) on the battery itself.
And if you are trying to run refrigerator
on 12V when dry camping
, forget it. Battery will not last long. Propane
, or a lot of solar
(and sunshine, and extra battery too).
OP was clearly talking about an inverter, but some others have migrated to converter. Inverter: 12V DC in, 120V AC out. Converter: 120V AC in, 12V DC out.
