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.
Hmm. So let’s talk resilience; lighting, battery power tools, refrigeration, Mobility (mountain eBikes, with solar recharging would make for great post apocalyptic transportation), and many more things.
