FWIW I just put in an order for one of these so I don't have any basis for a review, but has anyone checked out the JOOS Orange solar charger? It appears to be a hardened solar charger with better capabilities than the norm. http://solarjoos.com/. Its available online and at local rei.com. I'll post a review after I've had a chance to use it for a while. My plan as usual is to deploy it as my charger when the power is out.
