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.

Errr I am pretty sure those are currently only in use in prototyping and research, did you mean a different battery technology?
Yeah, I think I meant Sodium-ion
That makes more sense. I'm still skeptical. Sodium ion is being sold as safer than lithium ion, but I just read a paper that shows its still worse than LFP. time will tell
