I don't know diddly about anything from Revolver. The eGo was orginally designed as a battery and cone that works with std. 510 atomizers. As such, anything "510" should work with it. Your refill interval will depend on what sort of cart or carto you put with it. The std. 510 cartridge doesn't hold a lot of
juice -- there are various numbers of drops cited here on the forum for that, and I used to bottom-fill mine with a syringe anyway, so I don't know. There are now eGo-specific atties, carts, and cartos, with varying
juice capacities, which are referred to as "mega" (or, if you're shopping at Wordup, "jumbo"). Most of the info about the eGo is in the 510 model-specific forum, so I suggest looking around there for discussions about the various carts and cartos.
