(I can’t disagree with you, cause you ain’t wrong. ;) I do probably need to clarify my point though.)
That is exactly my point about the device not being UL rated. More than once, I have needed to add or replace poor ground connections to the chassis of some device, when applicable. If there is a failure point, it’s usually where there were cost savings involved and generally not the charging circuit itself.
Most battery charging ICs have decent fail-safes for bad batteries. It’s just economical to use the same, or similar, generic IC across hundreds of products. (The TP4056 (and clones) is a decent example of wide adoption, but it’s not quite a 1:1 with this particular application.)
Again, it’s just something to look for when inspecting rando devices. To your point, cloned charge regulators may have deleted safeties, so that is a thing.
