My very unscientific experiment with the Jackery Explorer 500 powering the Ironman 65L dual zone.
Fridge parameters: Freezer set to 30F / Fridge set to 34F - both bins completely empty
Exterior temp was 57F @ 17:05 with both bins at 63F mounted inside the truck. Plugged in fridge to DC output of the Jackery with compressor set to max to bring down to set points. Took 36 minutes, and I saw a peak of 52W draw. Jackery was at 96% when temps were reached, then I swapped over to low compressor speed to maintain.
Opened both bins once each just to confirm it “felt cold.”
Jackery looks to be pulling a continuous 2W to keep the DC output alive and power what’s needed for the fridge with the compressor off.
Checked at 9:03 the next morning and battery capacity was at 84%. I’d average exterior temps between then and the morning to be about 45F.
Left it running in the 80 outside all day today and took the 200 for a day trip with the family. Exterior temps were 65F - 70F all day and just checked at exactly 17:05 for a full 24 hour run time (including bringing it down to set temps). It’s at 69% (heh).
Going to keep it running again through the night, but overall, I’m impressed! Both on the Jackery and the power draw from the Ironman 65L dual zone. A bit cooler temps than typical for Florida, but most of my trips are done in NC/GA/TN/SC area, so I don’t think it’s far off for climate for areas and time I use the truck. Also the bins were empty, so no cold stuff to keep the bins cold.
I anticipate this will do just fine. Changing out the factory 12V DC socket to a Blue Sea 1011 to charge up the battery while traveling, but otherwise a simple plug-and-play solution for someone that doesn’t do much more than a long weekend. Big bin for booze. Small bin for grub.
Overall, stoked. Time to put it to the real test.
