Electronic cigarette cartridges work by using a “wick” of sorts. Inside the mouthpiece there is a small plastic casing and inside this small plastic cup is material that absorbs the e-liquid. With prefilled cartridges this wick is already saturated with eliquid. With empty cartridges, it is necessary to fill the cartridge yourself. So why would refilling electronic cigarette cartridges yourself be better?
First, prefilled cartridges must be shipped a long way. In fact most are filled and shipped from China. Although there are rubber plugs in the cartridges, some e-liquid inevitably leaks out into the mouthpiece. Liquid that leaks out is not vaporized and generally ends up in the users mouth. So right from the start, the cartridge may not be 100% full.
Second, you get more vapor with a completely full cartridge. Electronic cigarettes work like this; the atomizer vaporizes the e-liquid closest to it first, i.e. the top of the cartridge. As you vape, the top of the cartridge dries up and the atomizer must work harder to vaporize the e-liquid in the bottom of the cartridge. It is very hard to get a completely dry cartridge without going through many puffs of “off and on” vapor. This can get frustrating to a long time smoker who is use to consistent drags. And although many sellers claim anywhere from 10 to 30 cigarettes per cartridge, we have found this to be exaggerated especially considering the last 60% of the cartridge is poor vapor. To get the best e-smoking experience, keep your cartridge full.
Lastly, refilling your own cartridges is cheaper and more environmentally friendly. We recommend using 5 cartridges for a 15 ml bottle of e-liquid. Using the equivalent in prefilled cartridges would take at least 45 cartridges.
As a downside, filling your own cartridges does take a little more effort. However, we do provide 5 empty cartridges with each kit and with each bottle of e-liquid. These cartridges come with rubber plugs and a small zip lock bag so you can prefill your own to minimize the leakage when traveling. It is still recommended to take your bottle of e-liquid with you because as mentioned above, it is best to keep your cartridges full.
One last note: refilling your own cartridges does not prevent you from getting eliquid into your mouth. This can happen with prefilled or ones you fill yourself (depending on how good you get a refilling). Here are a couple ways to help stop e-liquid from getting into your mouth:
1) Use a toothpick to push the cartridge out of the mouthpiece (shown here) and fill the cartridge while it is outside of the mouthpiece. This will help prevent spillage while refilling.
2) Get a paper towel and blow through the large opening of the mouthpiece onto the paper towel. Any excess eliquid in the mouthpiece will be blown through the small hole onto the paper towel. Please note there is a e-liquid “trap” at the very end of the mouthpiece. You may have to blow extra hard to clean the trap of e-liquid. This methods works for prefilled cartridges or ones you just filled.
