TCL T08WQ2S

The TCL T08WQ2S is certified at 400 kWh per year (based on 750 standardized hours), roughly $75 at the national average — though seasonal use means your real bill lands in a few months, not twelve.

The same unit costs $49 a year in North Dakota but $186 in Hawaii — electricity rates, not the appliance, make the difference.
