This is a 100w fan; how does it run on only 2&cent; a day?

It doesn't. I don't know how they got the figure. I guess they assume you run it less then 2 hours a day. I pay $0.11 a kWh so according to my math (and this is quick math) its roughly 1.2 cent a hour to run.

I have 2 of this and 2 of renogy 100w also and I get same output of around 250 at noon, this might just be normal .

My unit was installed to run 24 hours per day year round for ventilation reasons. It runs very quietly. Most of the noise is from the sound of rushing air at the discharge point.

I used a kill-a-watt to measure how much power is used. I'm assuming a worst case scenario of 24hrs a day operation and a power cost of 10 cents per kwh.In the fan high mode, the unit uses 65watts. 65watts x 24hrs=1560 watts /1000= 1.56kwh x .10= 15.6 cents per day1.56kwh x 30=46.8kwh x .10= $4.68 per month46.8kwh x 12=561.6kwh x .10= $56.16 per yearKeep in mind that your unit will probably never run anywhere near 24hrs a day so cost will be lower. Mine ran non-stop for 2-3 days and now it cycles on and off on low to easily maintain 40% humidity for 2100 sqft. For those interested, the unit draws 55 watts on medium, and 45 watts on low.

Not sure if just the fan is on. It's probably very low, I would guess 50-75 watts. This heater is great, I put it on the low heat setting, and keep it next to me when it's cold outside. This way, I can turn down my house heat and save tons of money. I would estimate that on the low heat setting, using this heater every-night, my electric bill only goes up another $15

No, but of course the fan will only run a one speed. And BTW, I'm very happy with this fan. It draws very little power. The pricing is the problem here, I believe I could sell tons of these fans if the price was lowered to about $125...

I really like this fan a lot. It can use two sizes of battery. I have two of the smaller size. The fan runs about an hour on low with the smaller one. I think the correct way to classify the battery is by milli amp hours. The larger this number is the more capacity and longer lasting the battery will be.

The fan only comes on at high demand, when the unit is generating a lot of heat due to the load. I have been using the unit daily in my semi to power my laptop, printer, and charge the phone, and have yet to put enough load on it to engage the fan. I did load it up when I first got it with a soldering gun and a vacuum, and the fan was virtually silent. This inverter does all its supposed to do, and more.

It uses very little energy and is so wonderfully efficient! We have a very low electric bill, and our Vornado runs almost 24 hours a day. I'll never buy any other fan than a Vornado! Love it!

I have not and that is with New England weather. It runs quite a bit. I will say that I have it configured for 750 watts because it is in a small bathroom. Obviously it would be different if it was set at max wattage.

I don't use the fan everyday, so I can't really say.But based on the times that I have used it. I have not seena hugh difference in my electric bill. Hope this helps.

Not noticeably since we were using fewer fans at the same time. We don't run it 24 hours though....

It seems to run so cool for some things that the fan never comes on. I have had the fan come on (which is pretty quiet) occasionally, and it was still running pretty cool. My thought would be that you'll be fine, as long as you have a clear path from the fan area to a good supply of air.

I installed the fan in my crawlspace on Saturday and set the humidistat at 50%. It has run nonstop for 3 straight days.

You do not want to run it with a generator because it is worthless! It is the most worthless item I have ever purchased. You are bettert 0ff operating a fan. It does not perform well.
