[QUOTE=robw;57790]I have now amassed a collection of e-cigs, liquids and have been finding problems and solutions. So I figured I would share what I have learned.

2. Blow it out. At the end of the day, take your atomizer off and blow it with you mouth from the end that the battery attaches to. This will free trapped liquid. You can blow it onto a paper towel, you will be amazed of the gunk that comes out from just one day of use. I find this method makes the next days usage feel like a new atomizer.

Is that what makes my cartridges look brown when starting to vape?

3. Over charge the new batteries. If it says 4 hours, go 12. If it says 6 hours go 12, if it says 8 hours go 12. if it says 12 hours go 12. In other words go 12.

My batteries haven't been lasting as long since I let them charge longer. ??? The longer time doesn't harm them?

4. Light draws. I used to draw hard and draw often. I would end up topping off and replacing batteries really often. I also noticed the vapor was less and I could taste a bitter oil on the tip of my tounge.
I started experimenting with light draws. On all e-cigs including the pipe and screwdriver, all you need is a light draw. On a auto cig, just draw hard enough so the light comes on. On a manual switch draw as light as you possibly can.
The reason I think light draws seem to provide more kick as well as more vapor is because the vapor is created under the mesh in the atomizer. When you draw hard the vapor is coming out of the mesh with un vaporized liquid. With a lighter draw, only the vapor comes out, the unvaporized liquids viscosity keeps it in the atomizer mesh. Also the vapor it self is leaving the mesh slower, so it is hotter. A hotter vapor means more of the molecules have been vaporized, and less chance you are bringing liquid into your mouth. I taste the flavors mixed in to flavored liquids more when I use a slower draw.

Can't seem to make this work for me. NJOY pen style.

5. I would not recomend allowing the cleaning cycle.

How do I know it's cleaning. Is that when the atomizer get really warm and the light blinks? It doesn't seem to blink very long though.
