A quick guide to appliance power consumption


  • Clothes Dryer 2 - 3kW
  • Dishwasher 1800 - 2800W
  • Electric single oven typically 1.8kW
  • Electric double oven could be upto about 4.8kW
  • Heater: 60W tubular heater to 3kW heaters
  • Evaporative cooler (mobile type on castors) 65 to 200W
  • Microwave 800 - 1700W
  • Toaster 800 - 3100W
  • Electric Frying Pan 1200W
  • Iron 1000W
  • Blow Hair Dryer 1000W
  • Larger electric hob and possibly a set of ovens. Peak loads of 12kW would not be unrealistic - although obviously diversity would apply, and that will reduce the typical operating average load considerably.
  • Coffee Maker 800W
  • Vacuum 600 - 1700W

900W is the EU enforced power limit for domestic vacuums now, although older machines of 1800W to 2kW are common. You can go as low as 160w with an upright Oreck. Much lower handheld vacs are of limited use

  • Washing Machine 2 to 2.5kW
  • Fridge/Freezer 60w - 200W

Fridges typically have compressors driven by induction motors, and inrush current on those can be 5 to 9 times normal operating current. Add to that the older ones may have a relatively poor power factor which makes them harder for a generators to drive. A TV should be an "easier" load even if notionally the same power consumption.

  • Television under 300W
  • Computer + Monitor 100 - 400W
  • Blender 350W
  • Electric Blanket 200W
  • Sewing Machine 50-100W
  • Light Bulb 2W to 500W (LED candle lamp to halogen floodlight)
  • Laptop 30W to 90W
  • Shaver 15W

Outdoor Power Tools:

  • Electric Mower 1500W
  • 10" Bench Saw 1500W
  • Weed Eater 500W
  • Hedge Trimmer 450W
  • Belt Sander 380W
  • Drill 200W (old) to 1kW
