I started on 14mg liquid from kingpin using a 510 with a personal charging case. I have had one battery this entire time and one atomizer, have killed neither. I bought the case, auto battery, atomizer, blank carts, and my first batches of eliquid all from kingpin. Their prices are great and they have free shipping. I am now smoking Johnson Creek tennesee cured 18mg RPG and it's my favorite, just ordered 30ml at 11mg as I am trying to taper down. I find the reduced PG from johnsons doesn't irritate my mouth and it's seriously yummy stuff. The only mod I made was to clean out the nasty fibers in my atomizer, works much better now and it's been several days of very regular smoking. I keep my charging case attached to my computer and just put the cig in there when I'm not using it to keep the battery charged. The case is always charging on the computer via USB. Then when I go anywhere I take a little plastic dropping bottle of liquid and a couple spare carts in my case. The case holds two spare carts with thier caps and you can store the atomizer with a cart in it, which I recommend. The case keeps the battery charged all day. I just store the whole thing in the case all the time. I also clean my case, battery, carts, wicks, and atomizer every couple of days with 91% alcohol, which is what I have around. I hear 100% is better, but haven't tried it. 91% works fine for me. I'm just using the standard wick thats comes in the carts. The importiant things with these seems to be regular cleaning, keeping things wet, and keeping things charged. We buy new blank carts in addition to cleaning and reusing carts once in a while. And always sample and order your eliquid before you run out. Unless you live in a cool city, you can't really just go down the street and buy more liquid. Also, I choose lower nic levels becasue I'm a one cig a day social smoker. Now of course I vape all day long becasue it's so much cleaner. I just get my buzz and take a break, no measuing here. I physically smoke way more than I used to, so I'm lowering my nic to 11 so I can keep the buzz and stay at a lower level. I've been cutting the 18 with a no nic sample of the JC original, but I love the tennesee flavor quite a bit. Hope this let's you know that we all do this a little bit differently. Find what works for you for equipment, liquid, and mods and enjoy it your way. I should also note that I just dropped my case with my cig in it in a glass of whisky on the rocks. It's ok, it appears to be fine. Tennesee cured indeed. Get some tweezers, some qtips and a metal or glass cup to clean things and a towel to dry things off. let the alcohol evaporate a bit before you start smoking right away. It doesn't take long to clean them at all for me, but I don't let stuff build up. Hope this helps someone out.
