I do quite a bit of camping and backpacking, so I would find a portable solar cell to power my smartphone and laptop quite useful. I would like the solar cell to:Have both 19 volt and 12 volt outputHave 2.4 amp USBWeigh less than 10 poundsFold in a way that makes it fit into a backpackCost under $200- this is the maximum I am willing to spend- no budgingI would also appreciate it supporting a 90 watt power cord like this one, as I would rather not buy another adapter.Optional: Have an on-board battery of over 10000 MAh.
Portable solar cell for camping and backpacking?
