I am running off the stock wiring - and yes, 3.6l. The Dometic fridge can since the Jeeps battery levels and shuts off if the the Jeeps battery levels drop to a certain point. Seems like after about 2 days the fridge slows down.
My 37 ARB does the same, monitors the battery levels and will shut itself down if battery gets too low. That said, i have never had to worry about it, even when I did a rim to rim in the grand canyon it sat for 2.5 days, jeep started right up and all food was still cold.
I have the ARB wiring kit out of my JKU, am planning on running it to the aux panel one of these weekends, but until then i'm going to use the factory 12v plug in back.
I'm kinda liking that power supply. Especially since I use a CPAP. This could really re-open some camping opportunities. thanks!Finally put in an order for the ARB 37QT Classic Series II. Dometic, Engel and SnoMaster were the other finalists. I also just ordered the FlexoPower Lithium 444 battery pack, and will run the fridge from there most of the time, and connect the 12V cargo area plug to the FlexoPower to charge that while driving/ wheeling. I wanted the back up power supply to have the option to use it for camp lights, charging electronics, possibly even a small fan or two on summer nights in the tent. Plus I will use the fridge in the Jeep and the family SUV, so having the lithium pack alleviates battery worries for when we tailgate or leave the fridge in the SUV for periods of time. The lithium pack will also be handy for power outages, and provides a starting point if I decide to add a solar panel down the road. I should have ordered these things earlier. I will be shocked if the fridge shows up before the next Jeep camping weekend in 6 days, so it might be one last trip with the cooler.

I haven't run the fridge solely off the power pack for more than 24 hours, but I estimate it will run it for at least 48 hours. I have the Jeep charge the power pack while driving around and we aren't usually stationary for more than about 12-15 hours max.
I just saw your post about the Costway Refrigerator Freezer. I purchased the 54QT about three weeks ago. Needed a second fridge for beer when large family stayed over weekend. I left it plugged into 110 and played with the low/med/high settings and it worked great holding around 55 beers at around 36 degrees all weekend. I moved it to my JLU using the rear DC plug and drove around for a day stopping for errands and it worked perfectly throughout my trip. Now it's sitting on my Sailboat running on the DC plug with no issues. I changed the settings to EVO so as not to drain my batteries and haven't noticed the battery charger working any harder then normal. I couldn't justify the cost of the ARB, Dometic, Engel, etc. I did buy the five year warranty through Amazon for extra protection, that brought total cost to around $535.00. So far I'me very impressed by this unit and it looks identical to the ARB 54 QT unit, just different colors. ARB's thermal bag fits great on it according to other posts I'e read and Jeepers recommend getting the ARB DC charging system with locking capability so the plug doesn't come loose during rough trail use. I hope this helps you out.
Nice. I have been reading a lot of mixed reviews about it. Some people said they were only getting 6 hours max out of it. Been looking at a brand called jackery. Similar price for their 290 and it has about 21ah. Similar solar panel features etc
I agree for sure on the versatility and usually much longer lasting but the weight of these new power packs are much much lighter than 46 pounds. Most are very small lithium 9x5x7in and weighing only 6lbs. I can put that under my seat.
You are right about the danfoss being the key to low consumption, and the big brands use them while some Chinese brands use copies of them. Snomaster, however, doesn't use the danfoss. They use their own. They'll use danfoss compressors in some units that they make for other brands, but they claim theirs is better and they warrant them longer. The LS35, for example, has their compressor and has a 7 year warranty. I think most of their fridges have a 5 year warranty.
