Dave, it seems to draw about 40 watts on
Eco mode. So the
solar panel might go a long ways towards keeping it alive. From my reading it runs about 30% of the time at 40 watts and the rest at about 8 watts or something like that.
My
Scamp has a 100ah LiFeO4 battery. I have a 100w
solar panel which I haven't yet hooked up. So I suspect I will be just fine boon-docking when I get the chance.
I also built a little battery box with 16AH of LiFePO4 (about 200wh) and all kinds of connectors. Mostly I use it for charging phones and tablets and to run a portable air compressor for my truck and trailer
tires. With the connectors I put on the box I could also power this
fridge for another day or so. Mostly I'll just use a 12v socket in the
Scamp or a 12v socket in my tractor.
