Well I have to pedal about 20 minutes to put back in the
75 amp/hr. SLA 12 volt that's 10 watt/hrs. the beauty of
it...like you say very efficient I can almost power it direct
almost....probably could if I had a variable speed drive....
but I'm satisfied the way it is by pedal helping the battery
I can have a cup of coffee in 10 minutes as the voltage to
the coffee maker is higher....higher = faster brew. But it is
really quite causual pedaling....in fact I can sip on the coffee
while I pedal the second 10 minutes of the 20 minute session.
Just hooked up to the battery....battery reading 12.5 and drops to 12
when I turn on the switch coffee maker draws 7.96 amps.
It is a really efficient PMA....I figure 30 watts leisure pedaling
for a cup of coffee ain't bad at all  :)

Economically great advice!

What?
$4 for a coffee at StarBucks?
$2 at McD's?
Income tax?
etc.

To make enough spendable money
to buy a cup of coffee in that time...
a guy would have to make $25 an hour????
LOL

My coffee taste just as good as $4 or $2 coffee maybe better....
Next time you're down this way I'll make you a cup !

....working on a treadmill gen today treadmill motor becomes a
generator if you go faster than cut in speed.....altho I could never
drink coffee while I was walking....
(coffee cup in front just out of reach.....)
