I hope it's on the way, but I don't think the Pioneer Na is yet a sign of this revolution. This detailed review didn't leave me in a hurry to go get one, anyway:

Actually came across this video independently a couple of days ago, and having never come across this gentleman before it was enough to convince me that his analysis is of negligible value of the "beg the conclusion" variety.

To wit, in his review he-

-dismisses environmental concerns with Li

-dismisses safety concerns with Li

-dismissed geopolitical concerns with Li availability. Something something "environmentalists!" (shakes fist at clouds) like with the environmental concerns.

-dismisses economic advances of Na

And then the overwhelming focus of his review is that if you deep freeze the battery, it charges slowly. This becomes the foundation of his criticism. Only firstly it's a self solving issue -- the battery warms as it charges -- but in most situations the battery will be in a heated (or will be self-heating) scenario and at an ideal temperature.

I'm no Na booster, and it seems like an incremental improvement in various dimensions for certain scenarios, but that video adds extraordinarily little value to the space.

I disagree with your conclusion about the video even as I think Na is an incremental improvement. I think the video hits solidly on why the Bluetti Na Pro product is not yet a good overall product. I still think it's promising (and I think the reviewer does too). I can see why you think he's dismissing environmental/safety/geopolitical concerns. But I don't think so; I think he's simply taking the perspective of what's the best product for someone who needs to live with this as a primary power pack that they use. Obviously, someone could weigh the concerns that you mention higher than the functionality of the power pack. But reviewing it in the context of performance doesn't equate to a dismissal of those, IMO.
