Finally a use for that useless cold heat battery operated soldering iron that has been gathering dust on your work bench. Uses 4 aa nimh batteries for 4.8 volts,
good for 2 days of vaping. With a 3 ohm carto it vapes like a charm. Please excuse the slow assembly in the how to video. I only had one of these so it was trial and error fix problems as we go. Total parts cost $7.00 (not counting the soldering iron which I got for Christmas) Video link below.
