The Evod Tank is a bottom coil clearomizer tank system that features replaceable atomizer heads. This unique design provides robust vapor production with clean flavor and reduced "wicking" issues. Unlike many other clearomizers currently available, the E-Vod is permanently attached and is filled from the bottom. This two-piece design makes it more efficient than other tanks with replaceable atomizer heads. Also, if the E-Vod atomizer head fails unexpectedly, the atomizer head can easily be replaced without the need to drain the e-juice within the tank. The tank has a capacity of approx. 2ml and 2.4ohm. Note: This Clearomizer is designed to fasten onto the outer cone threads of an Ego battery and features 510 threading.
