In my earlier blogs, I talked about doing a run test video to see how long my cooler would run on my Jackery Explorer 1000 power station without recharging. I posted a video of that test here, on YouTube today.
The idea is to show how long the cooler could keep running in a worse case scenario. Obviously, you want to add charge to your power station whenever you can. This is pretty easy when you are driving, and the power station is charging from your car’s 12v DC outlet, but when stopped and the car isn’t running, you are on battery power alone.
If my campground happens to have a 110v plug at my site, I generally plug in to keep the battery topped off. If not, I plug my solar panel directly into the Jackery (it is the same receptacle where you plug in your 12V DC plug or the plug from the 110v transformer.
We have only had one trip where battery run time has been an issue. Last year, camping at Great Smoky Mountains National Park, we had three straight days of rain and no sunshine at all. I didn’t get any solar charge at all on my Goal Zero Boulder 100 Briefcase Solar Panels. We were in a primitive site with no power, so we had to drive a few hours everyday to keep the Jackery charged. Wasn’t a big deal, because we were driving around anyway, but you get my point.
What I didn’t cover in my test was the differences in temperature settings. I almost always keep the smaller compartment at about 20 degrees to keep things frozen and make ice. It can be set as low as -7 degrees, but that would be a bigger power draw to maintain. The freezer setting obviously draws more power than if I was just using both sides as a refrigerator. In a bind, I could shut off the refrigerator side completely if I absolutely needed to keep things frozen, or set one or both sides at a warmer temp.
My conclusion from this test is that these two components work well together, and that the Jackery Explorer 1000 is large enough to adequately power the 75 Liter Dometic for almost 3 days without being charged. In most circumstances, I would recommend a power source at least this big (1000 kilowatt/hour) for this cooler. If you wanted an even bigger buffer, the Jackery Explorer 1500, introduced last year, would power it for about 4 days.
This was my first video blog and it is pretty basic, but I’ll get better as we go! I hope you found it helpful.
