We have a Nova Kool conversion with the freezer. The compressor is variable speed, If the engine or battery charger are on the compressor will cool the freezer quicker. Normally it draws about 2 amps and uses about 40 ah/day, slightly more if it gets hot out. Our old Cold machine drew 6 amps when running. The freezer is nice for long trips which we rotate freezer packs from the cooler to refreeze them.
