There's a known issue with the Lithium version of the Goal Zero units. From what I understand they 12V output on them are unregulated. So you won't/can't run a 12V fridge off the cigarette lighter without a work around. You need to run two adapters that GZ sells, an anderson plug and a 12v regulated converter. This is with all their lithium units, from 400W to the 3000W units. I have the GZ 400W Lithium and tried my Dometic 35L on it and true enough it didn't work via 12vdc. I never went around to get the adapters because I run a dual battery system but just wanted to test it out.

As well from what I understand the GZ 400W Lithium unit, I'm not sure about their other ones, is NOT LiFePO4 if that matters. I've seen some user reports of the GZ 400W Lithium and it seems to power a fridge for around 12-24 hours. Not the best IMO. I assume they probably just run a bunch of 18650 cells in a daisy chain.
A more expensive and better option is the Dometic PLB40. It uses LiFePO4 cells, is regulated, just as small as the GZ400W, has anderson plugs whereas the GZ400W doesn't, and from what I've seen can run a fridge 48-72 hours. The unit was specifically built to run their brand of fridges with the ability to charge electronics as a bonus. I think GZ adopted the opposite purpose, they built their units to charge electronics and people then tried to adapt it to run fridges since they already had them. I've even seen someone trickle charge their house battery off the Dometic after they ran the power down and it gave it enough charge to start after a few hours.

To this date I've found very little use for my GZ 400W Lithium since I already run a dual battery system. It's a nice unit for charging other electronics but if your intention is to run a fridge for a few days I'd look at other options, namely the Dometic PLB40. Too many limitations and work arounds with the Goal Zero units.
