Most modern deep freezers typically draw about 60–100 watts while running, with brief startup spikes around 150–200 watts, and older or very large units can momentarily pull several hundred watts. Over a full day, the average continuous power works out much lower, often in the 20–40 watt range for efficient deep freezers.

Typical wattage ranges

  • Modern household deep freezer (running): about 60–100 watts during active cooling.
  • Startup surge: usually around 150–200 watts for newer units, but older models can spike up to 300–800 watts.
  • Older / less efficient deep freezers: often 100–300 watts while running, with higher surges.

Average power over 24 hours

Because the compressor cycles on and off, the average power over a day is much lower than the running wattage.

  • Measured averages across many deep freezers are around 19–40 watts continuous when spread over 24 hours.
  • This corresponds to roughly 0.5–0.9 kWh per day or about 172–346 kWh per year for modern units.

Quick way to estimate your freezer

To get a closer answer for your specific deep freezer:

  1. Check the label or manual for rated watts or amps × volts (for example, 1.5 A × 120 V ≈ 180 W).
  1. Treat that number as the maximum running power; the true 24‑hour average will likely be a fraction of that (often around one-third to one-quarter for efficient modern models).

Example ballpark numbers

  • Small to mid-size, modern deep freezer: label may say ~150–200 W, but average closer to 30–70 W over 24 hours.
  • Large or older deep freezer: label may be 300–500+ W, with higher spikes and a higher daily average.
