I bought my Casio Exlim specfically for cycling because it fits in my front shirt pocket while on a neck strap. I got the idea from a fellow
Nutter up to this point my main camera had been a Fuji Finepix 2600 that uses AA batteries, but it was bulky and hard to keep at the ready. It did great for "planned" pictures but I wanted something that I could whip out, punch on button and be ready to take pictures. I chose the Casio over several other cameras for a couple of reasons, one was the quick recovery time, another the battery life is out standing. It can take over 400 pictures on a single charge. The down side is the size of the charger base it requires. I plan on buying a second and possibly a 3rd battery pack if the need ever arises. As far as charging stuff I have plopped my butt in a seat a local restaurant an plugged my cellphone into the wall plug near my table while I eat a good lunch. Many of the stop and robs have an outside pay air pump...with a plug in handy

I love the idea of a solar charger and have looked into using my hub generator as a charger. Just haven't needed to go any further with the idea at this point.
