How much life in average do you get when using at 11~12 watts, and what atties do you use?
I've only done 10w which the atty last me only a week. But that atty wasn't in a very good condition to start with.
Right now I'm using the Ikenvape HV 306 atty. This particular one measures 3.1 ohm and I'm set to 6.1v (5.9 under load). Some of those volts are being drained by the voltage indicator (i think), but I'm
assuming that most are getting to the atty. That should put me in the 12watt range. I've used other brands too, don't know which ones sorry, but mostly the IKV. I haven't popped one of them yet (since I've started on vv in June) so can't tell you of life expectancy yet

- But I have switched them out between LR, SR and HV. I'd say that between the atties I'm using consistently they've each gotten at least 6 weeks of use and still going.
I always remove the wick (don't like the taste), keep them super wet (juicy), and when the taste starts to go (1-2 weeks) I clean them with ISO alcohol using a syringe until it drips in an unobstructed stream from the hole (ew, sounds gross), rinse with water, blow out and air dry overnight at least.
I'm psyched, but also kinda bummed. They are lasting so long that I haven't bought the newer model IKV atties (like i06 or stealth) since I still have several of the older version's to go! My favorite atty is the 306 - just seems warmer with stronger flavor than the rest - I guess since I'm vaping closer to the coil ;-). I've only recently discovered the cannon drip tip and it improved the 306 for me, better draw and somehow more flavorful - have no clue why it seemed to affect the flavor???
