Little portable fan.

[CTyankee]

Upstairs. At my computer, hottest room in the house. And I am cool due to my little blue fan, keeping me cool on two D batteries.

this was my brilliant idea and I found this perfect fan in my supermarket. It is sitting on my desk as I type and I feel fine.

We have central air but upstairs it just doesn't hack it. Glad I invested a few bucks in this fan or I wouldn't be typing this.

1. Fans are the best. Set up a couple blowing air from different directions

and let evaporation take care of the rest. Sounds like your portable fan is the perfect device.

2. It's even better if you use rechargeable batteries.

I use them for an O2Cool fan I keep at my desk. While one set of batteries runs the fan, another set is being charged/recharged.

3. and where do I get them?

4. Hardware stores.

Get NiMh batteries. Nickel Metal Hydride. Get 4 of them and a charger. Could run as much as $50.

They are 1.2 volts as opposed to 1.5 of alkalines, so your fan will run slower. You can't recharge alkalines.

You will have to do the math, if NiMh are for you.

10. She needs D batteries. n/t

16. The alkaline cell voltage will drop below the NiMH cell voltage fairly quickly.

Look at the chart that compares alkaline vs. NiMH discharge curves (voltage):

Especially under heavy loads, the NiMH cell's discharge curve is nearly flat, when compared to that of the alkaline cell.

7. You can get rechargeable batteries in most hardware stores. . .

. . .Ace, True Value, Lowes, Home Depot, Best Buy, Target, etc.

Battery chargers are a little tougher to find - it mostly depends on what size batteries you use.

Your best bet would be an Energizer Recharge Universal Battery Charger, which can acccommodate a variety of battery sizes.

This is the one I use:

Yes, between the charger and the batteries it does cost $$ upfront, but then, you can use them again and again and that means fewer spent batteries going into the garbage after only 1 use. These things really pay for themselves within 1-2 years.

Good luck and good hunting.

9. Thanks for all the good info.

14. Avoid the Energizer NiMH "D" cells, though, unless you want a D cell with the capacity of an AA.

They're rated at 2500 mah. That's typical capacity for an AA cell. A NiMH D cell should be at least 4 times that.

I suspect that Energizer is selling D cells with the guts of AA cells. In any case, they're quite the ripoff.

On edit:
Even if you don't mind the lower capacity of the AA cell in a D cell application, you can buy inexpensive adapters that allow you to use a real AA cell in place of the D cell. Much lower capacity, but could be useful in an pinch.

6. Ya know

if you set that bad boy in a dishpan you could cover the front with a towel and pour water over the top when it's dry and you'll have a nice little swamp cooler...

8. pretty too.

11. Speaking of folding fans, I found these little pop up fans. The work like

those windshield screens and fold up small enough to carry in a pocket or small purse.

I've given them away to family and lady friends and they love them.

12. That was my first thought.

Cha-ching!

13. Get a USB fan...I have 2

They are both USB and/or battery, and you can also plug it into an outlet with a USB adaptor plug.

The fans are available with 2 and 3 speeds. Target, Bed, Bath and Beyond, CVS... They are everywhere for under $15.00

15. I have one in my purse.

When everyone else is sweating bullets, I take out my handy little fan and cool off. (Two D batteries)
