Price is per 1 cartomizer
Each Cartomizer contains dual 3.2 ohm coils in parallel giving a total resistance of approximately 1.6 ohms.
These produce great amounts of vapor due to the greater heating area of the dual coils but have less potential to burn due to the higher individual resistance of each coil. (They'll still burn if they run dry, so make sure to refill!)
These hold about 25 drops of e-liquid. New improved filler material is more absorbent.
NOTE: that these are not sutiable for eGo, 510, 901 or mosfet driven type batteries. These are meant to be used with 3.7 volt mods with a switch capable of handling 2 or more amps. Simple testing shows that although these are low resistance, they work wonderfully on 5 and 6 volt devices. Your results may vary and the protection circuits on some batteries at higher voltages may see these as a short and not work.
