We have been car camping for years always looking for ice every few days. Tried dry ice but that gets expensive every few days. Picked up the JP30 during the 2023 Amazon Prime sale. I am powering it with a Ecoflow River Pro. Used in in Northern California for two days in 100 degree heat. It kept things at near freezing but it eats way more power than testing it in the garage with a few cans of beverages in it. This size was more than sufficient for two people and three days of camping. Super happy with the unit. Size is perfect for the back of my crew cab truck. I like having the display on top of the cooler. The new bluetooth app is great too. Your at home test and real world experience will be very different if its working in 100 degree temps.
