Something people may not realize is that it wouldn't be very difficult to rig up an 18650 (or similar) pack of the requisite voltage to make this thing portable without the need to fiddle with butane. "Wired" doesn't have to mean "attached to wall socket." With a pack of 8x Samsung INR18650-25Rs (3.6V 2.4Ah each) you could run this iron for over an hour at max draw, though you'd likely want to add a voltage regulator so you're not feeding 28.8VDC into the iron.
From the "comments" page: http://www.seeedstudio.com/depot/Mini-Soldering-Iron-US-Standard-ShapeBC2-p-2494.html?ref=newInBazaar&ref=banner_depot "Halo Peter, operation voltage can be 12V - 24V, and electric current is 1.4A - 2.7A. But 24v with 2.7A make temperature increased quickly. Yes the power adapter works with 19V and 2.1A."

infowolfeWhy would you want to run all 8 in series? It'd be far better to run two parallel banks of four batteries arranged in series (14.8v, 18650s, or any li-ion battery, are multiples of 1.23v).
As long as you're past nominal voltage, there's no difference between running 12v and 24v. Wattage is wattage.
A single pack of 3 lithium-polymer would probably work fine. Li-poly discharges a bit differently than most other battery types and 11.1v would likely be enough.

AusgeflipptThis device doesn't have a buck or boost transformer inside. It connects your power source directly to the heating coils, so at higher voltages it draws more power and heats up faster. Take a look at the datasheet I linked above.
