How to read the chart

  • Ranges are real spreads, not errors. Where sources disagree, the range runs from the lowest to the highest figure any of them gives. Lowe's figures are cautious sizing numbers and sit at the top end.
  • Starting watts are the total for the first moment of start up, as the source lists them. "No extra" means the source lists no starting surge, and "Not listed" means none of our sources gives a figure. To add several appliances together, use the generator size calculator.
  • Daily kWh is running watts times the example hours shown, divided by 1,000. The hours are our own example, not a measurement, so scale them to how you use the appliance.
  • Fridges and freezers cycle on and off, so their label kWh beats any watts times hours sum. The fridge runtime calculator takes the label figure directly.
  • For a battery or power station, open the runtime calculator from any row and the matching appliance is added for you where we have a preset.

Frequently asked questions

How many watts does a refrigerator use?

A full size fridge usually runs on about 150 to 400 watts while the compressor is on, and needs a short surge of roughly 800 to 1,200 watts to start, according to Champion. Because it cycles on and off, an ENERGY STAR certified top freezer model uses about 1 kWh a day. Your energy label gives the figure for your model.

Which home appliances use the most watts?

Anything that heats or cools a lot of air or water. In this chart a UK electric shower tops the list at about 9,000 watts, followed by electric dryers, tank water heaters and central air conditioning at several thousand watts each. Lights, routers and chargers use tens of watts.

Why do UK kettles and heaters use more watts than US ones?

UK homes run on about 230 volts and a standard 13 amp plug can supply around 3,000 watts, so kettles and heaters are built to use it. A standard US 120 volt, 15 amp outlet tops out near 1,800 watts, which is why most US space heaters are rated at about 1,500 watts or less.

How do I find the exact wattage of my own appliance?

Look for the rating plate or label, often on the back or underneath. If it lists only amps, Virginia Cooperative Extension suggests multiplying amps by volts to get watts. A plug in energy meter shows what it really draws, which is often less than the label for appliances that cycle.

Sources

Figures were taken from each source on 22 October 2026. They are typical values for planning. Your appliance's rating plate, energy label or a plug in meter always wins.
