I recently recieved this Flintstone solar charger from Sunferno to review and was pretty pleased with the results. This is one of the lower cost chargers so it kind of is what it is, but for the price it is definaltely worht having a couple of these small solar chargers around.
You can find them on Amazon here: http://www.amazon.com/sunferno-flintstone-smart-solar-charger/dp/B00RG5T9QI/ie=UTF8?m=&keywords=charger+solar
