generateor question...2250 watt output

Since gasoline consumption will be the same whether theres 100 watts or 2000 watts, I want to see what the maximum possible I can load on it.

In the last power outage, I had only my deep freeze on it and tv. My fridge is new and has a rating of 6 amps, which would be equiv to 720 watts. My deep freeze is only half the size so it should not pull that much.

I am fairly certain that a 2250 watt generator should cover this. Anyone disagree?

Gasoline use will go up a little with a heavier load, but not a lot.

What you have is a generator designed to cover a typical 15 amp fused circut. 1800 watts, of which about 1500 is useable.

The rating often is the 'startup' load, and not the continous load. Probably rated at 1800 or 2000 continous use?

Anyhow, you should be ok using 15 amps. I'd get nervious going past 18 amps for any amount of time.

You troubles will come when most things are running, and the freezer kicks in - start-up load of a motor can be pretty stiff, and mess you up. Your 6 amp fridge might pull close to 18 amps for a moment as it starts up......

It should be fine running tv, fridge, and freezer. I would suggest not plugging them all in at the same instant so they are starting at the same time. Plug in one and then the other.

Gasoline usage will vary with load, if you look up the specs on a generator they will usually list run time at 100% load, 50% load, etc.

If you want to conserve gasoline, you don't need to run the generator all the time. As long as you are not opening the fridge & freezer, they will stay cold for a few hours. You can run the generator for an hour, then turn it off for two or three hours. This will save considerable gasoline over running the generator constantly.

When I had a genset running my appliances, I simply filled the tank & let it run dry. Took about 2-3 hours, & all the things were plenty cool.

Actually letting the tank "run dry" is very hard on every thing.

As the gen is spittering and sputtering gasping for those last drops of fuel the speed of the gen is up and down-- and so is the voltage
--and so is the generated current. . . . . . . .
By doing that you stand a good chance of smoking items that are plugged in to the gen...........
I have witnessed this happen . . . . .back at the Y2K shindig a friends cheap @ss colemen 5k cost him dearly for doing that.

It is not a good practice to really max out a gen . . . . .
Leave plenty of head room and the gen will last longer.
