I bought my JP30 in about April of 2023 and went on a two week vacation from Washington State down through Oregon, Idaho, Nevada and into Utah where I visited 5 national parks. Being May it didn't get incredibly hot, but there were days the temperature was in the high 80's. I powered the the fridge with a Jackery Explorer 500 which was plugged into a 12V outlet in my car to keep it charged while I drove. I was careful to remember to unplug the Jackery from the car outlet at night so I didn't run my car battery down. I stayed in motels with my dog and brought food into the room from the JP30, so in 14 days I only ate in restaurants or fast food 4 times which in effect paid for the JP30 and then some. The food stayed cold and my sodas were always ice cold even on the hottest days. I had fresh fruit and deli meats and salads, desserts(no ice cream). I usually had 75 to 85 percent power left each morning after about 10 hours being parked. The weather was mostly cool at night because of the high elevations. I never had to worry about ICE (I'm legal). This is one of the best "fun" things I've bought and I've taken it on several trips now. I just bought a Bluetti AC70 battery which is 768 WH and will allow me to go longer without a charge while camping. I'm thinking about making another trip to Nevada to explore more of the state this Spring. Love this refrigerator!
