I bought a portable butane iron from Radioshack like 18 years ago. It's packed away somewhere but I use it when I need to solder big stuff like 10awg+ wires or just don't have electric where I'm working like when working on cars and such.

That’s the one that stopped working 🤷
Ah crap that ones my backup! Uh I guess I'd have to break out the acetylene, good looking nail, and some vice grips. XD
