Lets start with the 801 smokeless cigarette atomizer. Which is a big atomizer; The tip is rubbery/plastic and soft. If your going to drip into it using your E-liquid, you should use 6 at the very most. 7 may be over-kill. Drip it on the inside of the atomizer, when finish with this. Place the tip back on, grab your smokeless cigarette battery and attach them, then you can begin to vape. It comes with a standard battery which looks like a magic marker.
Next is the 901. vapor cigarettes are simliar to the 510′s. There normally filled up with polyfill. When you drip it functions in a normal. Drip about 2 drops using your E-juice bottle, unless there brand new then you can only do 3. Be careful though, Many folks argue about the E liquid dripping out of the bottom through the hole.
The 510 seems very small & short. The others have a bit of a longer atomizer & might have a silver or gold line around it. The 510′s have a cart. Some indivuals like to take the filling of the cart out and put about 3-4 drips in and then vape away. These also work with drip tips. There’s many drip tips you can buy where you can just put the drip tip on and you won’t have to take the cart off and you just drip it right into the hole. 901′s & 510′s have the same opening. So if there’s a 901 drip tip. It will fit on a 510 just fine. 801s are extremely wide and won’t work.
Last is the KR808D1 vapor cigarette cartomizer. The KR808D1 is very cheap in price, much cheaper compared to the other electronic cigarettes. The 510s are as long as the KR808D1 and are much less of a hassle and perform just as well. The KR808′s are female connectors & will require some sort of adopter to use them on your vapor cigarette battery.
