I recently purchased the Solar 15W. The first time I exposed it to sun the red LED on the IQ circuit board illuminated and appeared to start charging the attached device. The second time I exposed it to the sun, the red LED no longer illuminated and it does not appear to be providing a current for charging any longer. I can not find any instructions to reset the IQ circuit board. Is there a fix for this problem or do I need to return it for repairs / replacement?
Thanks in advance for any response.
