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

It all depends on three variables. The length of time you run it, the speed the fan is operating at/current draw, ie. low, medium or high, and the cost per kw you are being charged. Based on your 100w it would cost .02 cents a day running for 2 hours if you are being charged .10 cents per kwh (kilo watt hour). Myself we run it for about 8 hours and our kw charge after our 300kw allowance would run us about .08572 cents. For you to pay that .02 cents a day based on my cost of .10715 you would have to run the fan for 1.865 hours or just undr an 1 hour 52 minutes. If my math is right. Cost = kwh x cost per kwHope this helpsRicks It all depends on three variables.

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.

The fan has two speeds. According to the user's manual, it consumes 9 Watts when operating on the low speed. On the high speed, it consumes 12 Watts.

Runs all the time . Not sure about the watts . Very little effect on my electric bill, if that's what worries you .

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

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.

I have a pure sine wave 1000watts,,the fan runs all the time.,2second after i start it the fan comes on..annoying.,what about this .

very low energy use because of the small size of the fan. There are three fan speeds low, med, high. You set the humidity level you are comfortable with. When that level is reached the fan shuts off until the level drops and then it turns on again. We have a 1800 sq ft home and it keeps it at 40% humidity with no noticable spike in power use.

For me it lasts all day...I leave it on. At night before I go to bed, I refill it. I don't run it at its highest fan speed....that may make a difference. I've really found this to be relatively carefree. Let me know if you need anymore info!

It runs fine off a 12v battery. A 2.5x5.5mm plug and cord is included with the unit that plugs into the fan housing. There is no connector on the other end of the cord (all you get is bare + & - wires) but once connected the fan runs at about ~0.6 watts of power max on a 12v battery drawing ~0.05 amps. It would use less that 15 watt hours or just over 1 amp hour of power per day running 24x7. I plug it into my 12v Goal Zero Yeti power pack which charges from a solar panel and it works fine!

The fan should run when the unit is on. Contact the manufacture for specific operation questions.

You can do that , in fact it is a 12 volt fan . It is a very small computer size fan and does not use much electricity ,however over time it will run the battery down . I have a solar panel on my RV that keeps the battery topped off.

Its fine for DIY. Cut 2 sheet metal holes for the ducts and run wire for the low voltage line plus a water line. It was about 4 hours for me, probably 2 hours for a pro. Capacity is hard to judge, I have a 2500 sq ft house in a very dry area (desert) and in mid winter I need to leave the furnace fan "on" to keep the humidity up. If it only runs when the furnace is on, then it can't keep up.

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.

On the fan it says 0.5 amps, 60hz. The quantities are probably the draw when the fan is first turned on. Running the fan is less power, influenced by speed, how hot the fan gets, age, etc. I hope this helps.

the fan just work under high performance (when a large amount of power is required).Don't worry about it..

yes, no problem. It has small blocks, each reprensent a 30 minute period, so if you want 2 hours, just leave 4 consecutive blocks down and it will be on for just 2 hours. Personally I have a fan connected and it's set to run for 1 hour then stop for 30 minutes then 1 hour and stop for 30 mins, etc.

The fan was always running on mine. It came with a giant green sticker with leaves on it, so maybe there's a setting for that I missed, but I don't think so. I ended up selling mine so I can't check.
