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.
Unless your power bank has a built in charge controller, this should also include your power bank. At its core, a power bank is nothing more than a big ass lithium ion (or maybe potassium ion, if it’s newer) battery, just like the one in any other device.
i think you mean sodium ion?
Potassium ion?
You’re saying I can ditch the lemons and power my potato with bananas?
You’re better off using the bananas as nuclear fuel. I hear they’re radioactive
Indeed. They’re all the rage in China right now (I AM NOT A TANKIE). Some are predicting they’re the “next generation” of battery technology.

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