A quick scan of the specs tells me that this is, yet another, under-powered, over-hyped wanna-be-"green" failure.
The solar panel, under IDEAL conditions produces only 15W. "10-20 hours" to fully charge the battery (4point font: IF all 10-20 of those hours are in full noon day Sun.) Where is it high noon 24/7? Ah... perhaps this is useful in polar orbit. Here on Earth, outside the tropics, I can't imagine anyone would find this functional. Also, the USB port has a maximum output of 0.5A! That won't even charge an iPhone, and doesn't even come close to the 2A required for an iPad, or many other USB charged devices.
A nice idea, but an epic fail for solar power, yet again.
Well, maybe in an emergency situation where all you need is enough power for a radio and LED flashlight, this would suffice.

I am well experienced with this kind of power device. There are things you must adhere to and follow precisely to get any useful life out of it. This uses a Lead/Acid type of battery and does not work like a Nicad or Ni-MH battery. Maintenance is mandatory:
1. Once the battery has a full charge remove any charging device. This type of battery will hold 95% of its charge for a year! Keep it off the charger. These chargers are not regulated and will overcharge and boil the battery to death in as soon as 6 months. 12v lead/ acid batteries must float at 13.6 volts max.
2. Once this device is used it should be recharged shortly after. If it is run down low it must be recharged immediately. THESE BATTERIES CANNOT BE LEFT DISCHARGED FOR A LONG PERIOD OF TIME. They should be recharged as soon as possible... 6-8 hours max.
Although novel, my thoughts of the solar panel thing would be okay if the manufacturer put a voltage regulator circuit on the panel to limit the voltage to 13.5 - 13.8 volts. I did it to mine and power my shed out in the corner of my yard this way.
