Now that you mention it, it doesn't seem all that loud for a 2-stroke. Not quite like the old Yamaha 350 2-stroke twin with chambers...

They now have a large fan that is getting great reviews. Link is below.

I see as 139.00. That's not a bad price for a large hybrid fan.

I guess they were charging $100 for the battery.

Buy the cheap one and then get a 2 battery pack plus the charger and still be cheaper than the expensive one with only one battery and no charger.

Sizing generators based on load is a great way to save fuel. Keeping a large generator going full time when you only need it for a few hours a day means that you are spending fuel just to run the generator and not to power your loads.
Consider how many people spend their free time in the summer on a golf course, in a bass boat, at the beach, when the temps are close to one hundred degrees, but then say that they have to have AC when they get home.
If you have a couple fans, can cook with gas, and don't use your AC you could probably get buy with a small generator that burns very little fuel.

What about taking something like this apart and adding longer wires https://www.amazon.com/Solar-Powered...51806598&psc=1

You will have the fan any time the sun is shining.

Their is also the fantastic fan. It is supposed to be the most efficient 12 volt roof fan for campers.

USB fan, a $20 SLA battery for an alarm backup, a universal handlebar mount motorcycle USB bank. I've run one of the USB fans overnight that way with a 7ah battery.

IF YOU keep your eyes open and check Craigs List you can find Coleman 1800watt Powermates for fairly cheap, under $200.
I have one that is now going on 30 years old. Has been all over North America providing power in weather -40 to 100.
In all that time I have had it repaired..ONCE for a leaking gasket.

I use it to power the house in summer when we lose power . For things like water pump, frig, freezer I have bigger gens.

I like them so much I saw a great deal on one and bought it just because. I keep expecting the old one to die.. but it keeps on going so the "new" one may never be run much in my lifetime.
They burn about a gallon over 6-7 hours, so pretty economical.

Or pass on the Ryobi junk.

Dewalt DCB1800 Invertor w/batteries to run the 110v equipment you already own. Dewalt Flexvolt is an awesome line of equipment.

The batteries in those things are small which is why you only got 45 minutes out of it.

All you need is a deep-cycle RV battery and a 500 watt inverter to run the box fan you already have.

Battery $100, inverter $30 from Amazon.

https://www.amazon.com/BESTEK-Invert...XPHZK09&sr=8-3

If the box fan has no fancy remote control and electronic speed controls the modified sine wave inverter should work fine.

Charge the battery with the car battery charger you already have. - before the power goes out -

===

You can spend big bucks for SLA (sealed lead acid) or AGM (absorbent glass mat) in the 35 amp-hour range but a relatively cheap group 27 RV battery will do just fine and will run your fan longer.

Although they don't rate them in Amp-hours the typical flooded Group 27 battery has about 90 Amp-hours capacity.

Just get fans that run directly off 12 volts DC. Eliminates the conversion losses, greatly extending run time.

You can buy a 16 inch (or 12 inch) automotive 12v radiator fan for under $30 including shipping on ebay. They will blow your hat off. I have 3 of them. Get a 12v dimmer switch ($2) and you can still move a lot of air at less than half speed and I know they will run all day on a charged battery.

Better get a solar panel.... fuel would not be available in many emergencies. Even if there is fuel in the ground, it takes electricity to get it out of the tanks.

By the way.... just a few feet below everyone reading this in North America is 68 degree temperatures or lower (north of I-10) I'm lucky enough to have a spring. The water temperature is 68 and when I run it through a small ac radiator the fan will pull off the cool. I was cooling my off grid motorhome like this.... from 95 outside to 80 inside. It was under a shed too. That may not sound like much but the government says we should set our summer thermostats to 82 degrees in the summer. (Newsweek)

There are better fans for circulating air around a space, than a 20 box fan.
Box fans work in windows, for purging air in or out of a space.
For circulation around a room I am pleased with this Honeywell fan that is quiet, and it projects air further than a box fan, and uses less power.

The world runs on AC power, not 12 volts DC.

There's a good reason why Edison lost out to Westinghouse.

When I need to stay cool at night. I hook up my 1000wt inverter to my deep cycle 12vt battery and plug in my 12" el cheapo osc fan and I'm good for several hours on low. Can't say exactly, I always end up shutting it off as it cools down.
During the day. Harbor Freight solar, same battery and inverter.

That's true in regards to the world, but often a single small demand is better served with DC

Walmart has the O2Cool fans that run on a 12 volt wall wart or a set of D cells. The one I have draws about 480ma on High and less than half that on Low. I have a 12 volt 12AH AGM battery (from a UPS) that can run that fan on low for 24 hours. I can charge the battery with a solar panel or from the "Wait until daylight" solar-charged generator I designed and built (story for another post).

A small inverter hooked to your car will do the trick in a pinch. Just let the car idle.

I've had to do this after a hurricane. It does work well.

An idling car will use some fuel and I make no claims it's efficient. However, if you shut off the car's AC and blower, it won't be horrible. A modern 4 cylinder car will use about 0.13 to 0.18 gallons per hour idling with no load. Not much more running your fan.

There are only a few generators that will use less, the Honda EU1000 comes to mind.

Attach that to a battery and an inverter and you can run it as long as you have fuel to recharge the battery.
