It's not the worst thing in the world and the cloudy solar production might even be a bit better than other 45w set ups. But no idea what solar controller they are using. They are not all created equal.
If you could buy that locally vs. having to pay extra to ship something else it may not be bad. The flexibility in output voltages is interesting. It is big enough to charge an iPad or 2 at the output of the bigger Apple charger, if the USB is set up to output more than half an amp.
What would you like to do with solar? Just get your feet wet, or maintain some batteries that are not near a charger?
