So I was thinking about getting some kind of hand crank generator, for those cases where I just need to squeeze out a little more juice from my battery. And I was directed to this thing:
http://www.freeplayenergy.com/index.php?section=products&subsection=freechargeportableIt has a 7.5ahr battery, it excepts solar panels, and has a foot pump generator which can charge the battery or operate equipment between 2 and 3 amps. So I was just wondering if anyone has ever seen one of these in person, and perhaps know how much noise it makes while the foot pedal is being used. I'd like to know if it's a viable option in the section, for squeezing out enough power for an encore (or maybe even a short set).
