The Kanger Evod has a bottom coil feeding system. The atomizer heads are replaceable and the tank has a capacity of approximately 2ml. The Evod is eGo Cone threaded and NOT 510 threaded. This means that the clearomizer fastens to the outer threads of an eGo battery.
Bottom coil fed clearomizers provided much less wicking issues since the coil is submersed in liquid almost 100% of the time. This leaves no room for a dry or burnt taste.
The mouthpiece of the EVOD Clearomizer is permanently attached and is filled from the bottom. With this design it is possible to replace coil heads without emptying the tank. If the coil head fails suddenly the coil head base can be easily removed without having to remove any liquid.
When filling the Evod, unscrew the bottom coil head base. Hold the tank upside down and fill with approx. 2ml of eLiquid. With the tank mouthpiece-end down, screw the atomizer head back on. Do not get E-liquid in center hole since this runs directly into the mouth piece and will drain out.
