i would check the pictures of connectors and find out if you have a 510 atomizer connector, if yes, then I would suggest purchasing a 510 atomizer and some cartridges, you will get better flavor and vapor production, making the experience more like a cigarette.
I built a Puck 5 volt box for just a few bucks and it's night and day better than the mini-cig battery, with a Joye 3.2 ohm 510 atomizer. the "carto" or cartomizer that came with the mini-cig was disappointing.
the trick is to reach a certain wattage at the atomizer, to produce enough vapor and also make it warm so the nicotine on the
throat doesn't feel like pepper spray - there is a chart on this site showing how many watts are produced with different atomizer and voltage combinations, started by super user Ralph T and later expanded by Candre12...
I hope she doesn't mind me linking to it, i can't find the post right now...
by trying to get 8-10 watts, or 10-12 watts, you can get a closer simulation to a cigarette, and flavor becomes secondary, but nice.
post back which type you find it to be so others can search for it. thanks, i googled a bit but nothing came up that i could tell from.
