Harbor Freight and Home Depot offers a Jackery 400, which doesn't appear on Jackery's website. While I can assemble a comparable portable system it would consist of heavy objects connected by cords which is risky in mobile use. Does anyone have experience with it, particularly when charged from solar panels?

I'm not sure I buy into all the hype.  1st off Lithium Iron batteries are much safer if slightly less power dense than Lithium Ion batteries. A modicum of common sense should keep you more than safe.  I am currently running a 36V LiFEPo for a trolling motor.
If you want to lean into all of that Will Prouse has a fairly extensive library of videos on YouTube tearing into various batteries and battery assembly.  I think he is more focused on home power banks and server rack batteries, but there is a tremendous amount of practical knowledge there.  I don't recall if Will has torn into the portable power pack market to the same degree, but its worth a look see.
With most of these the cells are the same or similar (more powerful cells are becoming common).  The difference are in assembly quality, the BMS, and the quality of your inverter.
