12V outlets always-on hack

[ohmman]

Well, we had to return sooner than planned because smoke blew in from the Dixie fire and blanketed the entire region. Extremely disappointing, but I can at least provide positive news about the 240Wh power station. That battery bank, combined with a 100W flexible solar panel I had laying around, easily powered my cooler all night and day. This was despite the fact that we had a campsite with limited sun (about 4 hours a day). I also used the battery pack to pump up my inflatable paddleboard, so it's not a one trick pony.

I think I am likely to abandon my Tesla 12V project considering how simple and flexible this solution is. I probably would have preferred a slightly larger capacity unit, but since I was tight on time, I got what I did. If someone else is thinking about it, a ~500Wh unit should easily cover a pre-chilled electric cooler for about 48-60h without charging.

curious......what is the power draw on your cooler? I have a Jackery 300w battery pack with I used as a trial on my ACO Power cooler......the power draw on the battery is ~45w.....for cry from 48-60 hours....thanks

300Wh, I’m assuming you mean?

Your math, without a solar input, is 300Wh / 45W * 3/h = 20 hours.

I think I probably misspoke when I posted that three years ago. I likely was thinking about including the solar panel in the equation with the 500Wh pack.

no sweat....I put my Jackery with 69% in trunk last night....cooler was at 32F.....set temps 35F.....cooloer was full of sodas and water and other things.....this morning at 10:00am, Jachery was at 23%.....69-23=46 used. 46 used / 8 hrs = 5.65w per hrs...not too bad...I have s Jackery Pro 3000, Jackery Pro 2000 and Anker 767 along with 6-200w solar panels and a 100w panel for my other Anker EverFrost cooler.....I think I have enough power, but I was not sure of the cooler and it draw...I have learned that you must pre-cool prior to going on short trips.....longer trips should tale care of itself cooling wise becasue of the distance....local grocery trip requires pre-cooling.....
