TechwareLabs published a review of the Solio H1000 Hybrid Solar Charge.

Quote from the review: "You are stranded in the desert, forest, or on the road and need to make a call and find that your cell phone is dead. Just after you finish cursing your god of choice you remember you have the Solio H1000, plug it in and a short while later your phone is usable once again.
This is the concept behind the Solio H1000, a hybrid charger that is billed as a flexible solar charger that will restore life to lifeless cell phones and other USB charged devices. We test the Solio and bring you the fact and the fiction."
