U-Line UHFZ124-BS01B

Running around the clock, the U-Line UHFZ124-BS01B uses a certified 390 kWh per year — about $72 at the U.S. average rate, or $5.96 a month, the equivalent of a steady 45-watt draw. It sits near the bottom of the certified table — using 57% more than the median compact freezer (rank 128 of 134) — so the state you live in matters more than usual. The same unit costs $51 a year in Nevada but $206 in Hawaii — electricity rates, not the appliance, make the difference.
