The cartomizers can be filled a couple of different ways. We have a series of videos that demonstrate how to fill cartomizers. A brand new, blank cartomzier will hold 1mL of e-liquid or about 40 drops from the eyedropper caps.
If you are using our flex-tip cartridge needle you will want to fill this to the 1mL mark. You can fill this with the flex-tip on or with the flex-tip off, but before filling the actual cartomizer be sure to screw the blue flex-tip back into place on the cartridge needle. Take the black rubber mouthpiece off of the cartomizer to expose the fiberfill and the center air tube. Place the flex tip between the fiberfill and the outer wall of the cartomizer and fill while rotating the cartomizer. Make sure not to get any juice down the center tube. Let the cartomizer sit for a minute or two to allow the e-liquid to absorb.
If you’re using the dropper cap that came with the bottle of juice to fill, take the black rubber mouthpiece off the cartomizer to expose the fiberfill and the center air tube. Place about 40 drops of the Smoke Juice on top of the fiberfill, making sure not to get any down the center tube. Start with 20 drops, allowing some time for the e-liquid to absorb. From here, observe the fiberfill, if the top looks dry, add more drops. You will end up with 20-40 drops depending on the size of the drops. Let this sit for a minute or two to allow for the juice to absorb.
Once you have filled the cartomizer and let it sit, take a look at the fiberfill, if it is white and fluffy again a few more drops can be added. You will want the fiberfill to look wet and saturated. Also, you don’t want it too full. You don’t want juice pooling at the top. Place the black rubber mouthpiece back on to the cartomizer and you are ready to start vaping!
