I have a very lightly used NEBO Pinnacle Solar Power Station I used it only twice, once on a 4 day dip netting trip in Kenai and again when we went to the car launch out in Glacier View. I only charged it once, after my trip to Kenai and it’s still at 83% charged! It is a great machine I just don’t use it as much as I thought I would! And I spent to much money on it for it to just collect dust! So come take it off my hands and put it to better use!
