I bought my solar 14 roll from the internet with the vision of charging my laptop off the grid while traveling. After initial test I identified that it was unable to charge my laptop. I contacted Brunton and we arranged to exchange for another. After my second solar roll 14 arrived from Brunton, you can imagine how disappointed I was when testing identified that this solar roll 14 was also unable to charge my laptop. Bottom line is that if you are intend purchasing the solar roll 14 to charge your laptop in the sun (as the product description implies) then be prepared for disappointment. I have had 2 and neither of them have been able to charge a laptop. ..brian
