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.


Electric fire starter. Mesh nodes. Walkie talkies. Small computer with offline Wikipedia and Google maps. GPS may still be working for a while, so that would be useful to charge and use. Portable fans. MP3 player or other entertainment device. Camera. Small power tool batteries…
Yeah, in an apocalypse, a small about of electricity would be a luxury.
30W panel ain’t gonna do that.
Wrong!

Runs on a 5W panel… So yes, a 30W panel can certainly do that.
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?
