I have one of these https://webcat.cornwelltools.com/JP213123-Cornwell%C2%AE-Cordless-Soldering-Iron-p371692246 as well as a traditional wired soldering iron. While I like the cordless soldering iron's portability and it's fine for solder cups or solder splicing wire, it's not adaptable enough for me to use on a PCB or for micro solder and if I'm honest I'd want a micro solder setup for that anyway. I've owned expensive soldering irons and cheap ones (my current corded model I believe is one of ifixit's), the general problem is that I have too many random tips lying around that I don't know which iron they go to. Some are junk (because the iron broke etc). Some probably could be used interchangeably.

At least with the cordless one the tips are replaceable, and pretty unique in appearance so I know exactly which iron they go to.

The problem with the cordless one is the heat it can generate and the fact that it's not adjustable. The problem with the corded one is that I have to lug a 50' extension cord up to every plane to use it, and often there's not a safe place to put it down while it's hot so I have to prep every solder cup, joint, splice etc and then plug it in and turn it on. I've got stands galore and none of them is the safest.

I'd be willing to try this out just for the sake of the added protections it provides.
