Zline RFSV-36

Running around the clock, the Zline RFSV-36 uses a certified 569 kWh per year — about $107 at the U.S. average rate, or $8.93 a month, the equivalent of a steady 65-watt draw. Efficiency-wise it's unremarkable in a good way: within 1% of the median certified bottom-freezer refrigerator (rank 771 of 1458). The same unit costs $70 a year in North Dakota but $265 in Hawaii — electricity rates, not the appliance, make the difference.
