Someone: "you can't power a 5v fan with a single AAA battery."

 

Me: "hold my beer."

    interesting. i could use this to make a desk fan out of the wrecked PSU fan i have lying around. but i dont thing it wont make any air move with the blade design intended to do close range cooling.

    @Tech_Dreamer What I'm doing isn't the most practical. 

    I mostly did it to prove some idiot who thought that they knew what they are talking about wrong. 

     

    Typical AAA or AA batteries run at around 1.6v.  What I'm doing is wiring that one AAA battery to a boost converter which in layman's terms converters watts to volts. 

     

    However AAA batteries have horrible wattage potential and real low watt hours.  You're better off using a AA or even better running two AAs in series, that will give you 3.2v to work with, needing less wattage to be converted and thus greatly increasing battery life. 

     

    If you have a non functional laptop and you are brave, you can extract lithium cells which would be ideal since you can recharge them with the appropriate charger circuit.
