What size generator should I get for my freezer and refrigerator?
Unfortunately, there is no one-size-fits-all answer to what size generator you should get for your freezer and refrigerator. Instead, you want to select a generator size based on the size of the refrigerator and freezer combo. You can easily figure out the needed wattage by calculating the total starting watts.
How much wattage does a freezer generator use?
In general, most freezers have a running wattage between 300 and 800 Watts, while the starting wattage can be 2-3 times more. A 3,500 Watt generator has enough capacity to handle a freezer with a starting wattage of up to 2,900W and a running wattage of up to 700 Watts, which is enough to power most household freezers.
How much power does a generator use for a chest freezer?
This inrush current may be ~5x (or more) of the standard running power. So, depending on the specific freezer, this might equate to approximately 600 to 1,200 watts for generator loading. One of my portable gas generators is a small 2,000-watt Yamaha/Inverter, and it WILL run a chest freezer, even with the startup watts, no problem.
