Power Consumption Testing


Several years ago, I started wondering just how much electricity various home devices draw. This page contains the raw results of my measurements, using a P3 International Kill A Watt model P4400. All given values reflect the actual wattage at the wall, so they include any losses suffered by power supplies and the like.

  3. Minimum (non-standby) Watts drawn while active (lowest setting, if applicable)
  4. Average Watts drawn under normal use (middle setting, if applicable)
  5. Maximum (non-surge) Watts drawn at peak use (highest setting, if applicable)
  6. No specific model number known
  7. Power use grows steadily over the cooling cycle; L/M/H only affects fan speed
  8. Power use grows as it warms up, reaching the indicated upper limit
