since you've indicated that you might like a storage battery to go with this, the field opens up considerably. the mfg. of this, claims it will collect 200mah from the solar panel. it's 15 square inches verses 126 square inches unfolded, one tenth the size of the one you linked. the trade off being a modest drop in output. cheaper by quite a lot AND you get 5000ma of storage. both are about .5inch in thickness (folded in the case of the foldable) size was your initial criteria
