I'd add lithium batteries to the list. There's no way short of a teardown you can verify what battery vendor, which quality grade and especially which kind of protection circuitry was used - and even if there's analysis videos from youtubers available, there is no guarantee that the manufacturers haven't swapped stuff around during production runs to account for price and availability changes, or that the manufacturer doesn't suffer from supply chain issues.

Granted, established brands can be similarly impacted, but unlike some alphabet-soup dropshipper from Amazon, brands like Anker, Samsung, Apple or the likes have an actual reputation to lose so their incentive to keep safety in mind is way higher (and yes, even they can fail, both Samsung and Apple had their bad battery issues in the past).
