The wattage reference chart at right contains examples of what you can power with a portable generator.
Fridge power consumption generator.
Running an appliance on a generator.
More help on determining your power needs approximate starting wattage what is this.
Check the power tags or better yet measure the amperage draw with a clamp on ammeter or home energy monitor like a kill a watt meter.
These figures are approximate representations and the actual power consumption of your appliances may vary substantially from these figures.
In general appliances can be used on an auxiliary power generator gas solar inverter etc as long as it can provide the proper voltage 120v or 240v frequency hertz and can supply enough power to the appliance.
Another aspect that will affect the required size of your generator is whether your fridge also comes with a freezer.
While modern appliances have much lower power consumption around 300 400 watts even while the compressor starts to kick in the older types of fridges are going to need a bigger power supply around 300 1 200 watts.
That is why we have decided to create this list of rough estimates of wattage consumption of most common household appliances that people want to keep running at all costs.
See our section on power management to learn how to use a smaller generator to power more.
We hope these tables charts will help you to better estimate how big and powerful generator you will need as a backup source of power.
