SAPPHIRE SW243SZSS

Running around the clock, the SAPPHIRE SW243SZSS uses a certified 118 kWh per year — about $22 at the U.S. average rate, or $1.80 a month, the equivalent of a steady 13-watt draw. Efficiency-wise it's unremarkable in a good way: within 17% of the median certified compact-cooler refrigerator (rank 35 of 93). The same unit costs $15 a year in Nevada but $62 in Hawaii — electricity rates, not the appliance, make the difference.
