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 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
current sodium ion tech is great for stationary use and for cold climates. beyond that, lithium ion will be more useful
