I've had at least 3 other models of Igloo branded coolers in the past and have loved them all. We normally use a pair of trail mate journeys, so this is about the same volume as what we're used to, but the exterior is much more compact (no wheels or extra exterior parts/compartments) and not needing the ice will help get a lot more packed in. Where we use the trailmate for going camping, this will be used for a multi-week trip with multiple nights in hotels along the way to where we're going.
We're going to be staying about an hour from a grocery store, so having a vehicle refrigerator will help a lot with surviving more days between trips to the store. This will go in the back of our SUV each day and plug into the car for power, moving it to the hotel each night to plug in. I have a battery pack with 220Whr of capacity, but from my tests within my house it won't be enough to leave it running off of this in the car overnight.
I like that this has a good rubber seal and it sucks tight when you try to open it, so no air leaks like a typical cooler. I'd like to see it with a bit thicker of a wall so that it would run a bit more efficiently, though it really doesn't take that much power.
I'm also glad this isn't a thermoelectric cooler, like the ones that were popular in the 1990s. The unit doesn't make much noise, so it won't wake anyone up or keep anyone up in the hotel rooms, at least no more than my snoring.
From using rv refrigerators, I know one thing that will help me keep my food cool is a battery operated fan running inside the cooler to keep the air moving inside.
