This is my first post on this thread. Im 56 and have been vaping for about 1 1/2 years. I am currently vaping Kayfun lite+, KFL v2 and 3 Russian91% topping both mech mods and Provari. I run the same builds on all of them with great results. I also build my wife's KF mini's this way, she uses Evod type batteries. Both standard and spinners.
28g wire, 7 wraps around a 2mm screw driver wicked with organic cotton. Yes I have tried a lot of different builds and wicking materials, including rayon cotton (to much flavor loss for me). this gives me about a 1.3ohm coil that works great at 3.7v. It's nothing fancy but it gets the job done in spades. It's safe, durable and delivers good vapor and flavor. I rebuild them about once a month and dry burn and re wick about once a week or when ever they seem to need it.
No worries. I dry mine off as best I can with a paper towel then blow the water out of the bottom connection and build, wick, fill and vape. Just blow on them to clear as much water out of them as you can and you should be good to go!!
