Have to say about six months ago I weakened from my severe scepticism and bought a gas powered soldering iron. I'd resisted for many years but soon proved myself wrong. Problem was I've never smoked, so didn't really have much time for matches. So I bought one of these high voltage cigarette lighters, sort of Ronson styled, which you can charge from a bog standard USB port.
Now I've not only got a very good soldering iron (I wouldn't recommend it for PCB work, but for cables … WOW,) but I've got an instant ability to set fire to great public buildings and monuments.
