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.
That’s one of the half a dozen things you listed lol. You gonna power a computer off a 30W solar panel that realistically will give you about 6W? Power tool batteries?
Sure, a very small one, with a battery. My smartphone will charge off 5W.
I’ve got a mini Dremel that will charge off 5W USB. It ain’t gonna be fast, but it will definitely work.
You’re batting 0/3, still want to keep trying?
Strange how you ignored the example of yours that I specifically pointed out in the comment on just replied to - a pc.
