You mean like this one?

While they're quite amazing, they require 24V 3A DC, usually via
transformer. I also have have a nifty butane powered soldering iron from a
company in Japan:

Though, my came with a nice metal case. I actually use it with the hot
blower tip for heat shrink tubing more than for soldering. Really handy
thing.
