Simple electronics question
    #1437429 - 04/07/03 10:13 PM (14 years, 10 months ago)

I have a fan that I want to run from a 9v battery. How can I stop the battery from going flat so quickly?

MushyMay is a fictional character, as a result any information provided by MushyMay is also fictitious.

Get a fan that requires less power to run, or use a 9V ac adapter to run the fan and ditch the battery.

Edit: If you want to get really fancy, you would use pulse width modulation, depending upon your fan of course, to gain more life out of the battery. Do a search on pulse width modulation and brushless DC motor controllers for some insight. My guess is that this is more work than you are wanting.

Just another spore in the wind.
