power cart

This thing is a new take on the street vendors by having a portable stand that a passersby can stop pay a few bucks and get their cell phones or other wireless devices charged. The cart looks pretty simple with a wooden box design but I'm guessing the technical know how comes with the solar panel that is attached along with a crank on the side just in case the sun goes behind a cloud. I'm not sure how you would wire something like this but if you had the spare time it might be a good idea to make if you had some spare time on the weekend. One downside i could see to this is having to stand at the station while your cellphone or device is being charged and depending on how long your device takes to charge what you could do to fill that time. Also if it started to rain or lightning all of a sudden having your device get fried. Also things to take into consideration are, if more people plug in at once does it slow everyone's charge rate. Good idea overall for a street vendor. I have been stuck in public with a dead cellphone before and would have loved to have one of these around.
