I am about 15 hours in powering a fridge and I am slightly over half use. I was expecting maybe 36hrs but that looks out of the question even in this controlled environment.

22hrs in and the battery has kept the same indicator lights as it did this morning when I woke up. This is a test with AC. I will run another test with DC after.
Enthusiast III
It ended up being 28hrs on AC. Right now it's in the Jeep running off DC and so far seems to be using less juice. Time will tell. I'll probably test it this week more get some concrete numbers and start a separate thread regarding my results.
Enthusiast III
The test for AC was in a controlled environment without opening it up. It is full of drinks that were chilled prior to the test.
Now that it’s in my Jeep it’s DC and still full however it gets used multiple times a day. It’s a more realistic DC test.

40hrs into “real life” test in the Jeep. Still showing all 5 bars of battery life left.

Well I think I might have just found a decent portable power solution without having to go through the hassle of installing a dual battery system in my truck. I like that this is portable too. I can take it away from camp into the woods and run a saw to cut wood or use other power tools to work on upgrading or repairing deer stands. Thanks all who have posted real world results using it, helps a lot when making a decision like this!

Got mine yesterday, much lighter than I thought it would be. Looking forward to using it at Expo West next weekend.
The thing that's bothering me is the customer service. There is a lot of links from reviews out there pointing to products which are supposed to be on the US website and they aren't. I sent an email to them over a week ago asking about solar panels and other products. Haven't heard anything from them.

Smart. I'll keep that in mind.

So with DC and the current New England spring I was easily into 3 days and got an E1 error on my fridge. E1 is low voltage cut off. I went to plug it in tonight to charge and there is plenty of juice so perhaps I need to go to AC after 3 days for my particular fridge as I don’t have a way to turn off the low voltage shutoff. I will run that test next.
Educator I
check if your fridge has different settings for cut off/on, like mine has a low, med, high where it cuts off at different voltages.
these fridges are made for AGM batteries and cut off earlier than we would need for Lithium, wish there was a way to change that.....

It does and I set it to low. Not a huge deal just a small inconvenience and extra step. Battery is all charged up and about to go back in for this next test.

Goal Zero has a Buck/Boost adapter that regulates the output voltage to a constant 12V. The Lithium battery will then control when it shuts off. Kind of expensive at $40 though and it may need to be fitted with a connector compatible with your battery. It wouldn't be hard to make one if you have some experience with electronics.

I changed it up a bit. Test right now is plugged in via DC but I have the usb power input going so I can charge it while I am driving. I have about a 18 minute drive each way to work. So that’s at least 36 minutes of charging each day. Don’t think it will make a huge difference but it’s worth a test.
Educator I
This almost seems like a MUST HAVE deal, my test on DC lasted almost to the minute, 24 hours before the cooler shut off to save the battery and of course the battery is still showing full.....I dont mind the $40 bucks, just got to see if there is a anderson pole to something adapter I can get also....

I have one for my Yeti and it works great. I have only had it a for a month or so though.

I've got two bars left so it should make it through the night putting it at 48hrs with charging while I'm driving. I am going to try AC tomorrow after I get the low voltage cut off from the fridge. Curious to see how much longer I can go with that.
The one thing I've noticed is that a couple times the indicator status was incorrect. It happened on the 2nd test and it happened on this test. I got out to my Jeep checked the battery and it was showing 4 bars, I then started it and it showed 2 bars and it's accurate and staying at two bars now. Not sure how trustworthy that indicator is but we'll see.
Ultimately with in vehicle charging it looks like 48hrs is easy to accomplish in the spring in New England. I am curious to see it in the summer when it's hot and humid out. I'm thinking 24hrs will be hot and humid results.
