Our Double EVOD Premium Kits are an amazing value. Each kit contains 2 EVOD Tanks, 2 EVOD batteries, 2 spare atomizers, a USB charger, a wall charger, an e-liquid dispensing bottle, and an instruction manual. The EVOD is a newer version of an eGo-style electronic cigarette which also uses 510 threads, but with an activation button on the battery that is larger and more recessed than an eGo-style battery. The EVOD Tank is a BCC (bottom changeable coil) cartomizer, with its atomizer located on the bottom of the cartomizer so that the heating coil stays saturated with e-liquid, thus preventing the burnt taste experienced with many other e-cigarettes and cartomizers. The EVOD Tank holds approximately 1.6ml of your favorite e-liquid and has a slotted window which enables the vaper to see how much liquid is in the cartomizer. The EVOD’s atomizer/coil can be replaced easily and without any hassle. Available in Black, Blue, Pink, Purple and Stainless Steel.
