Power Port Solar Question

Nice write-up on the web page for the Solar Power Port. One important, not-so-little piece of info is missing, tho. The second thing any experienced hiker or backpacker will wish to know. How much does it weigh? Backpackers, especially, will want to know this. So do I.

Thanks!
