How Many Watts Does a Refrigerator Use? (and How to Measure Yours Exactly)

Quick Answer

A refrigerator draws roughly 100 to 400 watts while the compressor is actually running — but it doesn’t run all the time, so the number that matters is not watts. It’s kilowatt-hours per day: typically 1 to 2 kWh/day for a modern full-size fridge, 2 to 3 or more for older or oversized units. Because the compressor cycles, a fridge’s “watts” change minute to minute and no single reading predicts a bill. The meaningful measurement is cumulative energy — from a $15-30 plug-in meter, or a free one from many public libraries.

Which Smart Plug Measures Energy Usage? (And Which Just Switch On and Off)

Quick Answer

Look for the words “energy monitoring” in the product name or spec sheet — that is the feature that makes a smart plug a meter. A plug that measures energy contains a metering chip that reports live watts and cumulative kilowatt-hours to its app. The Kasa KP115, the Tapo P110M, and the Emporia Smart Plug all do this, and their spec sheets say so explicitly.[1][2][3] The widely sold basic class — Kasa’s HS103 and similar mini plugs — switches power on and off with no metering chip: the app shows on/off and schedules but never a wattage reading. The two kinds often sell within a few dollars of each other.
