An absorbtion fridge when burning propane, or less commonly oil, has a lot to recomend it.
A continual supply of propane or other fuel is required, but the consumption is small and a large propane tank will work the fridge for months.
Although some absorbtion fridges can also be run on electricity, this can not be recomended except briefly in a moving vehicle when propane burning might be unsafe.
An RV type absorbtion fridge if electricly powered can use more KWH a day than a full sized domestic model.
