This is guest post written by Via, an e-cig enthusiast living in Jacksonville, Florida. How long do cartomizers last? This is the question that I am most frequently asked. The answer is frustrating because there is no straight explanation. Cartomizers Depending on which battery I'm using, I use different types of cartomizers - CoolCarts and WOW carts, tank cartomizers in tanks, and eGo mega cartomizers. I prefer using low resistance cartomizers, usually 1.5ohms in tanks and eGo mega carts  (also 1.5ohms). Every carto has a lifespan of days, weeks or months, depending on how they are used, how often, and the battery they are used on. An automatic battery is easier on a carto than a  manual. The latter tends to shorten the life a little quicker, depending on how long the user holds down the button and how hot the carto gets.  I tend to swap out cartos when they get too hot. I am willing to live with a shorter battery cycle and shorter cart life in exchange for the nice, lush, juicy vapor I get when I use a  low resistance cart.    As you progress in your own vaping adventure, you will learn how your equipment reacts to your own special vaping style.   The beauty of vaping is that no two people have the same experience! Symptoms of a dead carto While vaping you might notice that the vapor is no longer as thick as it was when you started the cart. This is the first sign that something is wrong. First, does your battery need charging? My "first fix" is to swap out the battery.  I have a handful of batteries and several chargers, so I always have a few charging, and several in my "vape bag" fully charged.    When vapor production is weak I change to a fresh batt. If you put a carto, tank or mega on a fresh batt, and still don't get vapor production, the next simple fix is to adjust the post. View this YouTube video: http://youtu.be/HRx8eRZlXVg. If after adjusting the post, I'm still not getting a sizzle then I  know that the cart is really dead. If I still get a bit of sizzle I pop off the top of the cart and look at the filling to see how dry it is. Sometimes it just needs more juice.  If it still looks pretty juicy, it needs to be cleaned. Sometimes it's just clogged with half burnt juice and the wick is covered with debris. You can either clean or toss it. I always choose to clean it. On ECF Rick07 suggests using  a DenTck easy brush, while Lisa 66 recommends GUM Soft Picks to clean out the hole in the middle of the carto.  Rather than bristles, they have little rubber nubs; the brush part is wider at the bottom, come to a point and are flexible. One lasts a long time. When a regular carto starts to taste funny or seem clogged, I take the tip of the brush, push it into the carto from both ends and work it up and down. It will clear the hole and pull out darkened juice that has built up. Just wipe off the tip and reuse.  They help cartos last longer and taste better. Cleaning The last thing you can try is giving the carto a good cleaning.    Miss Gator and I both use a jewelry steam cleaner, which works very well. Or you can watch this YouTube video: http://youtu.be/aeBwmVejNkk. The next step If cleaning the cart doesn't work, you will need to replace the cart.  For help in choosing the right cartomizer, read this article by Morandir: "Technical Info About Replacement Cartos for Tanks".
