Short answer: No, the eGo-C type B
tanks will not work with the type A cones, you will need to have the new eGo-C type B cylinders and atomizers to use the type B
tanks.
Long answer: The eGo-C has two different atomizer housing styles just like the eGo-T does - the type A atomizer housing is cone shaped on both the eGo-T and eGo-C and the type B atomizer housing is cylinder shaped on both the eGo-T and eGo-C as well. Similar to the eGo-T, the smaller eGo-C type A
tanks require the cone-shaped eGo-C type A atomizer housing and the larger eGo-C type B tanks require the cylinder-shaped eGo-C type B atomizer housing. In other words, there's not just one type of eGo-C atomizer housing, there's two different ones (type A and B) just like there's two different housings for the type A and B eGo-T tanks. (There are photos of the eGo-C type A atomizers, housing and tanks
here on the Joyetech web site and photos of the eGo-C type B atomizers, housing and tanks are
here.)
