I live in the Desert of Nevada 110 - 115 F. And the fridge performed better then expected (75L), I took it hunting in central Nevada were the temps where somewhat lower 55 - 90 F. I kept my solar generator charged using a 100w panel… we have more than our fair share of sunshine here. I did pick up another 100w panel to give it a little more charge. The fridge never missed a beat! No worries about making ice runs, I couldn’t be happier. Side note: I ordered the fridge before noon it arrived the next day from California. It’s back at home in my garage keeping my drinks cold (average garage temp 105 F). It will travel with me on future trip just because it’s so KICK ASS convent!
