Keep in mind that I'm only talking about compressor refrigerators. The solid state, thermoelectric models are INSANELY inefficient.
That seems super high if it's a compressor fridge. As a comparison, a medium boat fridge with a Danfoss compressor runs 3.5a @ 12v, or 42w while running. And in my experience on boats, they run about 20-25% of the time in summer, not full time. Maybe the fridge is rated for that as the startup current? All motors, particularly compressors, have very high current during startup, easily 4x the running current.
This one uses 3.75w for example:

My last boat, a 32 footer, had a fridge that used 4a for about 20-25% of the day. So probably 300wH per day.
