What Is the Average Wattage of an Upright Freezer?

According to NV Energy's Appliance Usage Guide, an 18-cubic-foot upright freezer uses an average of 700 watts when set to automatic defrost. This figure is an average based on industry statistics. It may not apply to a specific manufacturer's product and depends on individual operation and appliance size.

An upright freezer set to automatic defrost using 700 watts translates to 1,830 annual kilowatt hours. Kilowatt hours are the units by which utility companies measure and price electricity. To save energy and money, consumers can set an upright freezer to manual defrost, which only uses 540 watts, translating to 1,250 annual kWh.
