List of the Power Consumption of Typical Household Appliances

Last Updated 28th October 2014

Turn that TV off if you're not watching it! It's wasting electrically!

How much electricity is it really wasting?, and would it not be better to switch off the 4 lights in the room?

The best way to compare the cost of running different appliances is to look at their power consumption, which is measure of how much power they use in Watts. The following list points out typical values for the wattage of some devices you would find in your home so that you can compare them.

Appliance Minimum Maximum
100W light bulb 100W 100W
25" colour TV 150W 150W
3" belt sander 1000W 1000W
60W light bulb 60W 60W
9" disc sander 1200W 1200W
Ceiling Fan 10W 50W
Clock radio 1W 2W
Clothes dryer 4000W 4000W
Desktop Computer 50W 150W
Dishwasher 1200W 1500W
Electric Blanket 200W 200W
Electric Kettle 2000W 2000W
Electric Mower 1500W 1500W
Electric Shaver 15W 20W
Fridge / Freezer 150W 400W
Hair Blow dryer 2000W 2500W
Home Air Conditioner 1000W 1000W
Iron 1000W 1000W
Laptop Computer 20W 50W
Lawnmower 1000W 1400W
Microwave 600W 1500W
Oven 2150W 2150W
Power Shower 750W 1050W
Strimmer 300W 500W
Submersible Water Pump 400W 400W
Table Fan 10W 25W
Toaster 800W 1500W
TV (19" colour) 70W 100W
Vacuum Cleaner 200W 700W
Washing Machine 500W 500W
Water Feature 35W 35W

An important point is also to bare in mind the length of time for which the device will be used. For example an electric blanket may be used for 2 hours, but a hair drier for 5 minutes. Therefore the blanket uses 200W * 2 hours = 0.4kWh. The hair drier uses 1KW * 0.0833hours = 0.08333 kWh. So using the blanket costs roughly 5 times as much as the hair drier.

All values reported here are estimates, you should check the appliance labels or literature to find out the correct power consumption.

These are helpful for calculating no. of units consumed by electrical appliances.

Yes, this was helpful in choosing a suitable generator for running a few appliances.

Does not show the COST of electricity. So only useful to kids (school project) who do not PAY for it.

Just bought a generator and this has helped me to identify what I can use at any given time running from the genie. Ian

Hi Judith, I think the measurement given is an average.
By Daft Logic on 23/03/2015
Am I right in thinking fridges are using electricity for only a third of the time they are switched on as they are designed to use a thermostat and stop using electricity when they are cold enough, then go on again? Is the wattage given in the table or, more importantly, on the plate at the back of a fridge for an average hour of fridge operation? Probably everyone knows this but me!
By Judith on 23/03/2015
Thanks, I have updated the Fridge / Freezer stats.
By Daft Logic on 18/03/2015
Fridge/freezer is actually much lower: 80W for a small fridge up to 300W for a single large unit.
