I’m only half kidding. I’m a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.
Not like this solves the issue. 30 watts (under ideal conditions) isn’t much but it’s a start.


Yeah, I think it’s pretty situational. I go to a lot of festivals and travel somewhat often, so it’d be useful for me. I also don’t have a permanent home (some day… <Sigh>)
I did think of stuff like a few days away, but solar takes much more time than that to make sense over more battery.
IIRC it was about a week or so before solar starts to make sense. 2 batteries or 1 battery 1 panel. After a month the panel option gives far more energy, but 3 days the 2 batteries is going to be more.
