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.


Doesn’t really make much of a difference which one you get. They all do the same thing and perform more or less the same. I happened to get a good deal on this one as it was only 30 euros so 1€/W though I doubt it’ll do full 30 watts even under ideal conditions. The brand is FlexSolar.
thank you!
