I gave you the model # XXXXX my original question. It is #ED19AKlLGRl

It did not pass through. Anyway, I would compute for a 1/3 HP compressor which is already higher than the standard 1/4 Hp which could be found on units 20 cubic feet and below.

In 1/3 Hp, the running wattage is 250 watts.
The starting wattage is about 1,750 watts.

In 1/4 Hp compressor, the running wattage is 190 watts
The starting wattage is about 1,300 watts.

If you are going to use a generator, I would suggest to still add a safety factor or 50 percent just to make sure the generator could handle the starting current. Use the standard consumption as the basis.

Can you be more specific about the starting wattage? I am planning on buying a 2000 watt generator and the starting wattage you provide is "about" 1750. That is cutting it very close. Is it possible to be more definitive about the starting wattage..."about" makes me very uncomfortable?

It is because I am not computing the whole fridge which is really very hard to accurately tell. There are still some small parts that consumes electricity which are the condenser fan, the evaporator fan, the electronics in it, etc.

The one that I gave is a rough estimate that is near to the actual power surge.

Anyway, if the unit could start right away, this power would just be drawn for about 1 second. But if the unit can not start right away due to so many reasons, then it would draw that power more than 10 seconds which could hurt your generator if it is just 2000 watts. That is why I am suggesting another 50 percent from the computed amount. So it would be at least 3000 watts.

Anyway, the other extra power that you have could be used in some other appliances once the fridge has already started.

It is always the fridge that is turned on first before the rest of the appliances is turned on.
