means I need to crank just a little bit
means I need to crank just a little bit faster for stable power and there it is
faster for stable power and there it is
faster for stable power and there it is I’m cranking this at about 100 rpm to
I’m cranking this at about 100 rpm to
I’m cranking this at about 100 rpm to develop the 5 volts this phone needs to
develop the 5 volts this phone needs to
develop the 5 volts this phone needs to charge if I crank slower the phone won’t
charge if I crank slower the phone won’t
charge if I crank slower the phone won’t power up and if I crank too fast I risk
power up and if I crank too fast I risk
power up and if I crank too fast I risk damaging it just for the challenge I’m
damaging it just for the challenge I’m
damaging it just for the challenge I’m going to see how long it takes to

in parallel with the system and connecting them to their respective
connecting them to their respective
connecting them to their respective terminals it takes about 15 minutes of
terminals it takes about 15 minutes of
terminals it takes about 15 minutes of cranking and it’s harder to turn the
cranking and it’s harder to turn the
cranking and it’s harder to turn the handle this time because I’m pushing a
handle this time because I’m pushing a
handle this time because I’m pushing a larger electrical current into the
larger electrical current into the
larger electrical current into the battery alright it’s done and a quick
battery alright it’s done and a quick
battery alright it’s done and a quick test on the meter shows that the battery
test on the meter shows that the battery
test on the meter shows that the battery is fully charged
is fully charged
is fully charged well that was educational I tried
well that was educational I tried
well that was educational I tried shorting the system out on my meter you
shorting the system out on my meter you
shorting the system out on my meter you got about 6 volts at 7 amps that’s over
got about 6 volts at 7 amps that’s over
got about 6 volts at 7 amps that’s over 40 watts of power I also tried hooking
40 watts of power I also tried hooking
40 watts of power I also tried hooking up an incandescent flashlight bulb and
up an incandescent flashlight bulb and
up an incandescent flashlight bulb and got it to fully illuminate a white LED
got it to fully illuminate a white LED
got it to fully illuminate a white LED was also tested and it was so bright it

there’s a makeshift electrical generator that you can make in a pinch that will
that you can make in a pinch that will
that you can make in a pinch that will charge batteries illuminate lights and
charge batteries illuminate lights and
charge batteries illuminate lights and generate around 40 watts on human power
generate around 40 watts on human power
generate around 40 watts on human power and it’s free that’s it for now if you
