While looking up a product URL for the SideWinder thread, I ran across the Freeplay FreeCharge Weza. We were just noting how tired your arm gets cranking these wind up devices and I was thinking that a foot-operated charger would be nice. Well, hello, the Weza can be charged using a stepping action, like those foot-operated air pumps. Since I use the StairMaster at the gym on most days, I would hope that I could get some decent power out of it. <img src="/images/graemlins/wink.gif" alt="" />

It's internal battery can also be charged by 110-240V AC or 12-18V DC power sources. For output, the website says it can jump start boat and car motors, as well as power your GPS, handheld radios, and mobile or satellite phones. Hmmm, rather intriguing.

Anyone have any experience with this product?
