(www.engadget.com)
This is a most excellent place for technology news and articles.
Let us know how it works. It sounds pretty cool, but ive been disappointed with battery powered soldering irons.
pinecil can be battery powered too and I've had a good time with mine. granted the battery is either a laptop power bank or a drill battery, but it's still portable enough for me
