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.
I’m getting solar panels and a battery later this month. It’s mostly to keep the bills cheap and the house green, but power outages are always in the back of my mind. There’s just so many ways they can happen
