Hey there. They are basically the same thing. They both have an atomizer which is the device that transfers the electricity to the coil to vaporize the e-
juice. The difference between the 2 is that the Cartomizer is pre-packed with filler material and factory e-
juice where an atomizer looks the same but has only a coil with small wick at the bottom that you drip your own
ejuice into. Cartomizer is what you see on the analog look-a-likes and the atomizer is like the Joyetech 510
