homemade laptop charger?
i am trying to build a homemade laptop charger. i plan to build a bunch a wet cell batteries out of mason jars and copper and zinc strips and some catalyst fluid such as salt water. each jar produces around .5 volts. i want to wire a bunch of them together to make a battery to power my laptop. my laptop has the standard AC input and a DC output of 19 volts at 1.58 amps, which is around 30.02 watts. i know that i will need a reducer or a regulator because i cant hook the battery straight to my laptops. where can i find one? i dont want to use a AC to DC inverter because i will need to generate too much energy from the batteries.
Laptops with AC input are rare. Most accept 12-15VDC. You could get that with 30 jars. But how much current can you draw from each jar? I suspect you'll need hundreds to thousands of jars.
