Pros: Good battery back up for your devices

Cons: the charging by sun does not work -

Review: I have had two, and neither could charge my phone for more than 5 mins after a day in the sun. Very disappointing. I even took it out to South Africa with me, and still could not charge the internal battery enough to power my phone....I now take it to work, charge it via usb, and use it as a battery back up - not what i bought it for at all...
