Thousand Suns has produced a portable solar generator packaged in a flight-case.
Unclip, fold out and position the solar panel using the fold-out legs and it will charge fully in six hours. The unit can also be charged using a mains charger in about four hours.
EnviroGadget has plenty more information and pictures of this sleek 4.1 kg solution to powering phones and fridges among other things. Mrs Green is also happy to read that the battery is 95% recyclable and has a life of about 10 years.
