These units , or I should say some of these units will act as freezers. Some have a freezer section and a cooler section. They will use more power running the freezer.
I freeze bottles of water or adult juice pouches ( wife likes Dailys Hurricanes) to put in the cooler with the cold drinks. Keeps everything cold and nothing gets messy or wet. When the ice bottle is partially melted the cold water is pretty cold.
I still use a small 6 can cooler even with the refrigerator. Take out what you are going to drink for the next couple hours. Put in additional drinks in the refrigerator to get cold. I cannot get into the refrigerator when driving but can reach the small cooler sitting on the floor in the back seat.
If you look at a truck stop they have small units that if things are cold will keep cold .
I advised on the larger refrigerator that the OP asked about to put cold stuff in as he wanted to minimize his battery draw. The unit he has will make warm drinks cold , even freeze them but uses a lot of battery power. By using shore power to cool the unit and putting cold drinks in , even some frozen plastic bottles of water it will use very little battery to keep everything cold.
He can, if he wanted to, carry a bag of ice and keep it frozen running his unit as a freezer . I know folks who routinely take ice cream .
